Enhancement of loading capacity of distribution system through distributed generator placement considering techno-economic benefits with load growth  

Science Journals Connector (OSTI)

Abstract Load growth in a system is a natural phenomenon. With the increase in load demand, system power loss and voltage drop increases. Distributed generators (DGs) are one of the best solutions to cope up with the load growth if they are allocated appropriately in the distribution system. In this work, optimal size and location of multiple \\{DGs\\} are found to cater the incremental load on the system and minimization of power loss without violating system constraints. For this a predetermined annual load growth up to five years is considered with voltage regulation as a constraint. The particle swarm optimization with constriction factor approach is applied to determine the optimum size and location with multiple DGs. To see the effect of load growth on system, 33-node IEEE standard test case is considered. It is observed that with the penetration of multiple number of \\{DGs\\} in distribution system, there is great improvement in several distribution system parameters. Moreover, the loading capacity of distribution system is enhanced through DG placement and its techno-economic benefits are also established.

Methods for Analyzing the Benefits and Costs of Distributed Photovoltaic Generation to the U.S. Electric Utility System  

SciTech Connect

This report outlines the methods, data, and tools that could be used at different levels of sophistication and effort to estimate the benefits and costs of DGPV. In so doing, we identify the gaps in current benefit-cost-analysis methods, which we hope will inform the ongoing research agenda in this area. The focus of this report is primarily on benefits and costs from the utility or electricity generation system perspective. It is intended to provide useful background information to utility and regulatory decision makers and their staff, who are often being asked to use or evaluate estimates of the benefits and cost of DGPV in regulatory proceedings. Understanding the technical rigor of the range of methods and how they might need to evolve as DGPV becomes a more significant contributor of energy to the electricity system will help them be better consumers of this type of information. This report is also intended to provide information to utilities, policy makers, PV technology developers, and other stakeholders, which might help them maximize the benefits and minimize the costs of integrating DGPV into a changing electricity system.

Optimization of catalyst system reaps economic benefits  

SciTech Connect

Champlin Refining and Chemicals Inc. is learning to optimize its catalyst systems for hydrotreating Venezuelan gas oils through a program of research, pilot plant testing, and commercial unit operation. The economic results of this project have been evaluated, and the benefits are most evident in improvements in product yields and qualities. The project has involved six commercial test runs, to date (Runs 10-15), with a seventh run planned. A summary of the different types of catalyst systems used in the test runs, and the catalyst philosophy that developed is given. Runs 10 and 11 used standard CoMo and NiMo catalysts for heavy gas oils hydrotreating. These catalysts had small pore sizes and suffered high deactivation rates because of metals contamination. When it was discovered that metals contamination was a problem, catalyst options were reviewed.

Development of an Integrated Distribution Management System  

SciTech Connect

This final report details the components, functionality, costs, schedule and benefits of developing an Integrated Distribution Management System (IDMS) for power distribution system operation. The Distribution Automation (DA) and Supervisory Control and Data Acquisition (SCADA) systems used by electric power companies to manage the distribution of electric power to retail energy consumers are vital components of the Nations critical infrastructure. Providing electricity is an essential public service and a disruption in that service, if not quickly restored, could threaten the public safety and the Nations economic security. Our Nations economic prosperity and quality of life have long depended on the essential services that utilities provide; therefore, it is necessary to ensure that electric utilities are able to conduct their operations safely and efficiently. A fully integrated technology of applications is needed to link various remote sensing, communications and control devices with other information tools that help guide Power Distribution Operations personnel. A fully implemented IDMS will provide this, a seamlessly integrated set of applications to raise electric system operating intelligence. IDMS will enhance DA and SCADA through integration of applications such as Geographic Information Systems, Outage Management Systems, Switching Management and Analysis, Operator Training Simulator, and other Advanced Applications, including unbalanced load flow and fault isolation/service restoration. These apps are capable of utilizing and obtaining information from appropriately installed DER, and by integrating disparate systems, the Distribution Operators will benefit from advanced capabilities when analyzing, controlling and operating the electric system.

Energy and reliability benefits of wind energy conversion systems  

Science Journals Connector (OSTI)

The electrical energy production and reliability benefits of a wind energy conversion system (WECS) at a specific site depend on many factors, including the statistical characteristics of the site wind speed and the design characteristics of the wind turbine generator (WTG) itself, particularly the cut-in, rated and cut-out wind speed parameters. In general, the higher the degree of the wind site matching with a WECS is, the more are the energy and reliability benefits. An electrical energy production and reliability benefit index designated as the Equivalent Capacity Ratio (ECR) is introduced in this paper. This index can be used to indicate the electrical energy production, the annual equivalent utilization time and the credit of a WECS, and quantify the degree of wind site matching with a WECS. The equivalent capacity of a WECS is modeled as the expected value of the power output random variable with the probability density function of the site wind speed. The analytical formulation of the ECR is based on a mathematical derivation with high accuracy. Twelve WTG types and two test systems are used to demonstrate the effectiveness of the proposed model. The results show that the ECR provides a useful index for a WTG to evaluate the energy production and the relative reliability performance in a power system, and can be used to assist in the determination of the optimal WTG type for a specific wind site.

Strategy Guideline: Compact Air Distribution Systems  

SciTech Connect

This Strategy Guideline discusses the benefits and challenges of using a compact air distribution system to handle the reduced loads and reduced air volume needed to condition the space within an energy efficient home. Traditional systems sized by 'rule of thumb' (i.e., 1 ton of cooling per 400 ft2 of floor space) that 'wash' the exterior walls with conditioned air from floor registers cannot provide appropriate air mixing and moisture removal in low-load homes. A compact air distribution system locates the HVAC equipment centrally with shorter ducts run to interior walls, and ceiling supply outlets throw the air toward the exterior walls along the ceiling plane; alternatively, high sidewall supply outlets throw the air toward the exterior walls. Potential drawbacks include resistance from installing contractors or code officials who are unfamiliar with compact air distribution systems, as well as a lack of availability of low-cost high sidewall or ceiling supply outlets to meet the low air volumes with good throw characteristics. The decision criteria for a compact air distribution system must be determined early in the whole-house design process, considering both supply and return air design. However, careful installation of a compact air distribution system can result in lower material costs from smaller equipment, shorter duct runs, and fewer outlets; increased installation efficiencies, including ease of fitting the system into conditioned space; lower loads on a better balanced HVAC system, and overall improved energy efficiency of the home.

NETL: Gasification Systems - Evaluation of the Benefits of Advanced Dry  

NLE Websites -- All DOE Office Websites (Extended Search)

Feed Systems Feed Systems Evaluation of the Benefits of Advanced Dry Feed System for Low Rank Coal Project Number: DE-FE0007902 General Electric Company (GE) is evaluating and demonstrating the benefits of novel dry feed technologies to effectively, reliably, and economically provide feeding of low-cost, low-rank coals into commercial Integrated Gasification Combined Cycle (IGCC) systems. GE is completing comparative techno-economic studies of two IGCC power plant cases, one without and one with advanced dry feed technologies. A common basis of design is being developed so that overall assumptions and methodologies are common in the two cases for both technical and economic areas. The baseline case, without advanced dry feed technologies, will use operational data from the Eastman Chemical Company Kingsport gasification facility in combination with DOE/NETL's Cost and Performance Baseline Low-Rank Coal to Electricity IGCC study for both cost and performance comparisons. Advanced dry feed technologies, based upon the Posimetric® pump currently under development by GE, will be developed to match the proposed plant conditions and configuration, and will be analyzed to provide comparative performance and cost information to the baseline plant case. The scope of this analysis will cover the feed system from the raw coal silo up to, and including, the gasifier injector. Test data from previous and current testing will be summarized in a report to support the assumptions used to evaluate the advanced technologies and the potential value for future applications. This study focuses primarily on IGCC systems with 90 percent carbon capture, utilization, and storage (CCUS), but the dry feed system will be applicable to all IGCC power generating plants, as well as other industries requiring pressurized syngas.

Cost/benefit analysis for video security systems  

SciTech Connect

Dr. Don Hush and Scott Chapman, in conjunction with the Electrical and Computer Engineering Department of the University of New Mexico (UNM), have been contracted by Los Alamos National Laboratories to perform research in the area of high security video analysis. The first phase of this research, presented in this report, is a cost/benefit analysis of various approaches to the problem in question. This discussion begins with a description of three architectures that have been used as solutions to the problem of high security surveillance. An overview of the relative merits and weaknesses of each of the proposed systems is included. These descriptions are followed directly by a discussion of the criteria chosen in evaluating the systems and the techniques used to perform the comparisons. The results are then given in graphical and tabular form, and their implications discussed. The project to this point has involved assessing hardware and software issues in image acquisition, processing and change detection. Future work is to leave these questions behind to consider the issues of change analysis - particularly the detection of human motion - and alarm decision criteria. The criteria for analysis in this report include: cost; speed; tradeoff issues in moving primative operations from software to hardware; real time operation considerations; change image resolution; and computational requirements.

Transportation system benefits of early deployment of a 75-ton multipurpose canister system  

SciTech Connect

In 1993 the US Civilian Radioactive Waste Management System (CRWMS) began developing two multipurpose canister (MPC) systems to provide a standardized method for interim storage and transportation of spent nuclear fuel (SNF) at commercial nuclear power plants. One is a 75-ton concept with an estimated payload of about 6 metric tons (t) of SNF, and the other is a 125-ton concept with an estimated payload of nearly 11 t of SNF. These payloads are two to three times the payloads of the largest currently certified US rail transport casks, the IF-300. Although is it recognized that a fully developed 125-ton MPC system is likely to provide a greater cost benefit, and radiation exposure benefit than the lower-capacity 75-ton MPC, the authors of this paper suggest that development and deployment of the 75-ton MPC prior to developing and deploying a 125-ton MPC is a desirable strategy. Reasons that support this are discussed in this paper.

SciTech Connect

This paper proposes a control method to regulate voltages in 3 phase unbalanced electrical distribution systems. A constrained optimization problem to minimize voltage deviations and maximize distributed energy resource (DER) active power output is solved by harmony search algorithm. IEEE 13 Bus Distribution Test System was modified to test three different cases: a) only voltage regulator controlled system b) only DER controlled system and c) both voltage regulator and DER controlled system. The simulation results show that systems with both voltage regulators and DER control provide better voltage profile.

Factor Influencing Logistics Service Providers Efficiency in Urban Distribution Systems  

Science Journals Connector (OSTI)

Abstract The increased urbanization and the awareness of freight transportation impacts have stressed the importance of City Logistics (CL) as a comprehensive approach aimed at mitigating the negative effects of distribution activities without penalizing social, cultural, and economic issues. In this context, a crucial role is played by logistics service providers (LSPs). This paper proposes an empirical analysis on the operational factors determining the level of efficiency of a LSP. This study represents an attempt to develop a panel of operational variables supporting the efficiency of the urban distribution system of LSPs. The potential benefits are both economic and environmental.

Targeting DSM for transmission and distributions benefits: A case study of PG E's Delta District  

SciTech Connect

This study describes the results of evaluating the impact of a variety of DSM programs on the capacity expansion plan of an actual distribution planning area in Pacific Gas and Electric Company's service territory. The study makes use of a number of new techniques to develop area specific marginal costs, loads and DSM load impacts. The detailed data is used to develop an integrated least-cost distribution plan for the area. The integrated plan is approximately 30 percent less expansive than the unintegrated distribution expansion plan. PG E is among a number of utilities that are now beginning to work on increasing the cost-effectiveness of DSM programs with the use of integrated T D planning. Most of these utilities are experiencing higher T D costs relative to their costs of generation.

Prognostic Health Monitoring System: Component Selection Based on Risk Criteria and Economic Benefit Assessment  

SciTech Connect

Prognostic health monitoring (PHM) is a proactive approach to monitor the ability of structures, systems, and components (SSCs) to withstand structural, thermal, and chemical loadings over the SSCs planned service lifespans. The current efforts to extend the operational license lifetime of the aging fleet of U.S. nuclear power plants from 40 to 60 years and beyond can benefit from a systematic application of PHM technology. Implementing a PHM system would strengthen the safety of nuclear power plants, reduce plant outage time, and reduce operation and maintenance costs. However, a nuclear power plant has thousands of SSCs, so implementing a PHM system that covers all SSCs requires careful planning and prioritization. This paper therefore focuses on a component selection that is based on the analysis of a component's failure probability, risk, and cost. Ultimately, the decision on component selection depend on the overall economical benefits arising from safety and operational considerations associated with implementing the PHM system.

Community Earth System Models (CESM) is one of US's leading earth system modeling systems, which has over decades of development history and embraced by large, active user communities. In this paper, we first review the history of CESM software development and layout the general objectives of performance analysis. Then we present an offline global community land model simulation within the CESM framework to demonstrate the procedure of runtime tracing of CESM using the Vampir toolset. Finally, we explain the benefits of runtime tracing to the general earth system modeling community. We hope those considerations can also be beneficial to many other modeling research programs involving legacy high-performance computing applications.

Reliability improvement of distribution systems using SSVR  

Science Journals Connector (OSTI)

This paper presents a reliability assessment algorithm for distribution systems using a Static Series Voltage Regulator (SSVR). Furthermore, this algorithm considers the effects of Distributed Generation (DG) units, alternative sources, system reconfiguration, load shedding and load adding on distribution system reliability indices. In this algorithm, load points are classified into 8 types and separated restoration times are considered for each class. Comparative studies are conducted to investigate the impacts of DG and alternative source unavailability on the distribution system reliability. For reliability assessment, the customer-oriented reliability indices such as SAIFI, SAIDI, CAIDI ASUI and also load- and energy-oriented indices such as ENS and AENS are evaluated. The effectiveness of the proposed algorithm is examined on the two standard distribution systems consisting of 33 and 69 nodes. The best location of the SSVR in distribution systems is determined based on different reliability indices, separately. Results show that the proposed algorithm is efficient for large-scale radial distribution systems and can accommodate the effects of fault isolation and load restoration.

Distributed Delays Stabilize Ecological Feedback Systems  

Science Journals Connector (OSTI)

We consider the effect of distributed delays in predator-prey models and ecological food webs. Whereas the occurrence of delays in population dynamics is usually regarded a destabilizing factor leading to the extinction of species, we here demonstrate complementarily that delay distributions yield larger stability regimes than single delays. Food webs with distributed delays closely resemble nondelayed systems in terms of ecological stability measures. Thus, we state that dependence of dynamics on multiple instances in the past is an important, but so far underestimated, factor for stability in dynamical systems.

Economic benefits of an economizer system: Energy savings and reduced sick leave  

SciTech Connect

This study estimated the health, energy, and economic benefits of an economizer ventilation control system that increases outside air supply during mild weather to save energy. A model of the influence of ventilation rate on airborne transmission of respiratory illnesses was used to extend the limited data relating ventilation rate with illness and sick leave. An energy simulation model calculated ventilation rates and energy use versus time for an office building in Washington, D.C. with fixed minimum outdoor air supply rates, with and without an economizer. Sick leave rates were estimated with the disease transmission model. In the modeled 72-person office building, our analyses indicate that the economizer reduces energy costs by approximately $2000 and, in addition, reduces sick leave. The annual financial benefit of the decrease in sick leave is estimated to be between $6,000 and $16,000. This modeling suggests that economizers are much more cost effective than currently recognized.

Thermal distribution systems in commercial buildings  

NLE Websites -- All DOE Office Websites (Extended Search)

Thermal distribution systems in commercial buildings Thermal distribution systems in commercial buildings Title Thermal distribution systems in commercial buildings Publication Type Journal Article LBNL Report Number LBNL-51860 Year of Publication 2003 Authors Diamond, Richard C., Craig P. Wray, Darryl J. Dickerhoff, Nance Matson, and Duo Wang Start Page Chapter Abstract Previous research suggests that HVAC thermal distribution systems in commercial buildings suffer from thermal losses, such as those caused by duct air leakage and poor duct location. Due to a lack of metrics and data showing the potentially large energy savings from reducing these losses, the California building industry has mostly overlooked energy efficiency improvements in this area. The purpose of this project is to obtain the technical knowledge needed to properly measure and understand the energy efficiency of these systems. This project has three specific objectives: to develop metrics and diagnostics for determining system efficiencies, to develop design and retrofit information that the building industry can use to improve these systems, and to determine the energy impacts associated with duct leakage airflows in an existing large commercial building. The primary outcome of this project is the confirmation that duct leakage airflows can significantly impact energy use in large commercial buildings: our measurements indicate that adding 15% duct leakage at operating conditions leads to an increase in fan power of about 25 to 35%. This finding is consistent with impacts of increased duct leakage airflows on fan power that have been predicted by previous simulations. Other project outcomes include the definition of a new metric for distribution system efficiency, the demonstration of a reliable test for determining duct leakage airflows, and the development of new techniques for duct sealing. We expect that the project outcomes will lead to new requirements for commercial thermal distribution system efficiency in future revisions of California's Title 24.

Energy information systems (EIS): Technology costs, benefit, and best practice uses  

SciTech Connect

Energy information systems are the web-based software, data acquisition hardware, and communication systems used to store, analyze, and display building energy data. They often include analysis methods such as baselining, benchmarking, load profiling, and energy anomaly detection. This report documents a large-scale assessment of energy information system (EIS) uses, costs, and energy benefits, based on a series of focused case study investigations that are synthesized into generalizable findings. The overall objective is to provide organizational decision makers with the information they need to make informed choices as to whether or not to invest in an EIS--a promising technology that can enable up to 20 percent site energy savings, quick payback, and persistent low-energy performance when implemented as part of best-practice energy management programs.

Can distributed generation offer substantial benefits in a Northeastern American context? A case study of small-scale renewable technologies using a life cycle methodology  

Science Journals Connector (OSTI)

Renewable distributed electricity generation can play a significant role in meeting today's energy policy goals, such as reducing greenhouse gas emissions, improving energy security, while adding supply to meet increasing energy demand. However, the exact potential benefits are still a matter of debate. The objective of this study is to evaluate the life cycle implications (environmental, economic and energy) of distributed generation (DG) technologies. A complementary objective is to compare the life cycle implications of DG technologies with the centralized electricity production representing the Northeastern American context. Environmental and energy implications are modeled according to the recommendations in the ISO 14040 standard and this, using different indicators: Human Health; Ecosystem Quality; Climate Change; Resources and Non-Renewable Energy Payback Ratio. Distinctly, economic implications are modeled using conventional life cycle costing. DG technologies include two types of grid-connected photovoltaic panels (3kWp mono-crystalline and poly-crystalline) and three types of micro-wind turbines (1, 10 and 30kW) modeled for average, below average and above average climatic conditions in the province of Quebec (Canada). A sensitivity analysis was also performed using different scenarios of centralized energy systems based on average and marginal (short- and long-term) technology approaches. Results show the following. First, climatic conditions (i.e., geographic location) have a significant effect on the results for the environmental, economic and energy indicators. More specifically, it was shown that the 30kW micro-wind turbine is the best technology for above average conditions, while 3kWp poly-crystalline photovoltaic panels are preferable for below average conditions. Second, the assessed DG technologies do not show benefits in comparison to the centralized Quebec grid mix (average technology approach). On the other hand, the 30kW micro-wind turbine shows a potential benefit as long as the Northeastern American electricity market is considered (i.e., oil and coal centralized technologies are affected for the short- and long-term marginal scenarios, respectively). Photovoltaic panels could also become more competitive if the acquisition cost decreased. In conclusion, DG utilization will represent an improvement over centralized electricity production in a Northeastern American context, with respect to the environmental, energy and economic indicators assessed, and under the appropriate conditions discussed (i.e., geographical locations and affected centralized electricity production scenarios).

Performance benefits of telerobotics and teleoperation - enhancements for an arm-based tank waste retrieval system  

SciTech Connect

This report evaluates telerobotic and teleoperational arm-based retrieval systems that require advanced robotic controls. These systems will be deployed in waste retrieval activities in Hanford`s Single Shell Tanks (SSTs). The report assumes that arm-based, retrieval systems will combine a teleoperational arm and control system enhanced by a number of advanced and telerobotic controls. The report describes many possible enhancements, spanning the full range of the control spectrum with the potential for technical maturation. The enhancements considered present a variety of choices and factors including: the enhancements to be included in the actual control system, safety, detailed task analyses, human factors, cost-benefit ratios, and availability and maturity of technology. Because the actual system will be designed by an offsite vendor, the procurement specifications must have the flexibility to allow bidders to propose a broad range of ideas, yet build in enough restrictions to filter out infeasible and undesirable approaches. At the same time they must allow selection of a technically promising proposal. Based on a preliminary analysis of the waste retrieval task, and considering factors such as operator limitations and the current state of robotics technology, the authors recommend a set of enhancements that will (1) allow the system to complete its waste retrieval mission, and (2) enable future upgrades in response to changing mission needs and technological advances.

Laser spark distribution and ignition system  

DOE Patents (OSTI)

A laser spark distribution and ignition system that reduces the high power optical requirements for use in a laser ignition and distribution system allowing for the use of optical fibers for delivering the low peak energy pumping pulses to a laser amplifier or laser oscillator. An optical distributor distributes and delivers optical pumping energy from an optical pumping source to multiple combustion chambers incorporating laser oscillators or laser amplifiers for inducing a laser spark within a combustion chamber. The optical distributor preferably includes a single rotating mirror or lens which deflects the optical pumping energy from the axis of rotation and into a plurality of distinct optical fibers each connected to a respective laser media or amplifier coupled to an associated combustion chamber. The laser spark generators preferably produce a high peak power laser spark, from a single low power pulse. The laser spark distribution and ignition system has application in natural gas fueled reciprocating engines, turbine combustors, explosives and laser induced breakdown spectroscopy diagnostic sensors.

Distributed computer controls for accelerator systems  

SciTech Connect

A distributed control system has been designed and installed at the Lawrence Livermore National Laboratory Multi-user Tandem Facility using an extremely modular approach in hardware and software. The two tiered, geographically organized design allowed total system implementation with four months with a computer and instrumentation cost of approximately $100K. Since the system structure is modular, application to a variety of facilities is possible. Such a system allows rethinking and operational style of the facilities, making possible highly reproducible and unattended operation. The impact of industry standards, i.e., UNIX, CAMAC, and IEEE-802.3, and the use of a graphics-oriented controls software suite allowed the efficient implementation of the system. The definition, design, implementation, operation and total system performance will be discussed. 3 refs.

Cost Benefit Energy Analysis of the Building Envelope Systems with Ener-Habitat  

Science Journals Connector (OSTI)

Abstract During the last decade, housing construction in Mexico has increased dramatically, despite the economic and financial crises, it is one of the main drivers of the Mexican economy; the government has supported programs to develop social housing in order to assist low-income families. This type of initiatives has allowed low-income people to own a place to live, but it has also promoted the spread of housing developments with house models of similar characteristics in the very diverse geographical and climatic zones of Mexico. Even though some of the dwellings have few differences depending on the region they belong to, they do not reflect climatic adaptations. The correct selection of the envelope materials is one of the first and most effective passive strategy that must be considered in the design of a housing. However, just selecting the materials by knowing their thermal properties is not enough to make an appropriate decision about the construction system. For this reason, we need a tool like Ener-Habitat, which allows a quick assessment of thermal and energy performance of a building system consisting of several layers, through the time-dependent calculation of heat transfer, suitable for high thermal mass materials, such as those generally used in Mexico and the climates of Mexico with high solar radiation and large temperature swing during the day. The study propose a method to analyze the cost and energy benefit of building systems, and as example analyzes some walls building systems, in a hot-dry climate city of Mexico, during the air conditioning season. This tool allows, at early stages of architectural design, quick assessments for decision taking on the building systems choice, in relation with better energy performance. Ener-Habitat was created by researchers from six academic institutions in Mexico and was funded by the National Council for Science and Technology and the Ministry of Energy of Mexico.

The work documented in this report represents another step in the ongoing investigation of innovative and potentially attractive value propositions for electricity storage by the United States Department of Energy (DOE) and Sandia National Laboratories (SNL) Energy Storage Systems (ESS) Program. This study uses updated cost and performance information for modular energy storage (MES) developed for this study to evaluate four prospective value propositions for MES. The four potentially attractive value propositions are defined by a combination of well-known benefits that are associated with electricity generation, delivery, and use. The value propositions evaluated are: (1) transportable MES for electric utility transmission and distribution (T&D) equipment upgrade deferral and for improving local power quality, each in alternating years, (2) improving local power quality only, in all years, (3) electric utility T&D deferral in year 1, followed by electricity price arbitrage in following years; plus a generation capacity credit in all years, and (4) electric utility end-user cost management during times when peak and critical peak pricing prevail.

Distributed Robust Power System State Estimation  

E-Print Network (OSTI)

Deregulation of energy markets, penetration of renewables, advanced metering capabilities, and the urge for situational awareness, all call for system-wide power system state estimation (PSSE). Implementing a centralized estimator though is practically infeasible due to the complexity scale of an interconnection, the communication bottleneck in real-time monitoring, regional disclosure policies, and reliability issues. In this context, distributed PSSE methods are treated here under a unified and systematic framework. A novel algorithm is developed based on the alternating direction method of multipliers. It leverages existing PSSE solvers, respects privacy policies, exhibits low communication load, and its convergence to the centralized estimates is guaranteed even in the absence of local observability. Beyond the conventional least-squares based PSSE, the decentralized framework accommodates a robust state estimator. By exploiting interesting links to the compressive sampling advances, the latter jointly es...

Optimal planning of distributed generation systems in distribution system: A review  

Science Journals Connector (OSTI)

This paper attempts to present the state of art of research work carried out on the optimal planning of distributed generation (DG) systems under different aspects. There are number of important issues to be considered while carrying out studies related to the planning and operational aspects of DG. The planning of the electric system with the presence of DG requires the definition of several factors, such as: the best technology to be used, the number and the capacity of the units, the best location, the type of network connection, etc. The impact of DG in system operating characteristics, such as electric losses, voltage profile, stability and reliability needs to be appropriately evaluated. For that reason, the use of an optimization method capable of indicating the best solution for a given distribution network can be very useful for the system planning engineer, when dealing with the increase of DG penetration that is happening nowadays. The selection of the best places for installation and the preferable size of the DG units in large distribution systems is a complex combinatorial optimization problem. This paper aims at providing a review of the relevant aspects related to DG and its impact that DG might have on the operation of distributed networks. This paper covers the review of basics of DG, DG definition, current status of DG technologies, potential advantages and disadvantages, review for optimal placement of DG systems, optimizations techniques/methodologies used in optimal planning of DG in distribution systems. An attempt has been made to judge that which methodologies/techniques are suitable for optimal placement of DG systems based on the available literature and detail comparison(s) of each one.

The final phase of the tubular SOFC development program will focus on the development and demonstration of pressurized solid oxide fuel cell (PSOFC)/gas turbine (GT) combined cycle power systems for distributed power applications. The commercial PSOFC/GT product line will cover the power range 200 kWe to 50 MWe, and the electrical efficiency for these systems will range from 60 to 75% (net AC/LHV CH4), the highest of any known fossil fueled power generation technology. The first demonstration of a pressurized solid oxide fuel cell/gas turbine combined cycle will be a proof-of-concept 250 kWe PSOFC/MTG power system consisting of a single 200 kWe PSOFC module and a 50 kWe microturbine generator (MTG). The second demonstration of this combined cycle will be 1.3 MWe fully packaged, commercial prototype PSOFC/GT power system consisting of two 500 kWe PSOFC modules and a 300 kWe gas turbine.

Performance and Economic Analysis of Distributed Power Electronics in Photovoltaic Systems  

SciTech Connect

Distributed electronics like micro-inverters and DC-DC converters can help recover mismatch and shading losses in photovoltaic (PV) systems. Under partially shaded conditions, the use of distributed electronics can recover between 15-40% of annual performance loss or more, depending on the system configuration and type of device used. Additional value-added features may also increase the benefit of using per-panel distributed electronics, including increased safety, reduced system design constraints and added monitoring and diagnostics. The economics of these devices will also become more favorable as production volume increases, and integration within the solar panel?s junction box reduces part count and installation time. Some potential liabilities of per-panel devices include increased PV system cost, additional points of failure, and an insertion loss that may or may not offset performance gains under particular mismatch conditions.

Scoping Studies to Evaluate the Benefits of an Advanced Dry Feed System on the Use of Low-Rank Coal  

SciTech Connect

The purpose of this project was to evaluate the ability of advanced low rank coal gasification technology to cause a significant reduction in the COE for IGCC power plants with 90% carbon capture and sequestration compared with the COE for similarly configured IGCC plants using conventional low rank coal gasification technology. GEs advanced low rank coal gasification technology uses the Posimetric Feed System, a new dry coal feed system based on GEs proprietary Posimetric Feeder. In order to demonstrate the performance and economic benefits of the Posimetric Feeder in lowering the cost of low rank coal-fired IGCC power with carbon capture, two case studies were completed. In the Base Case, the gasifier was fed a dilute slurry of Montana Rosebud PRB coal using GEs conventional slurry feed system. In the Advanced Technology Case, the slurry feed system was replaced with the Posimetric Feed system. The process configurations of both cases were kept the same, to the extent possible, in order to highlight the benefit of substituting the Posimetric Feed System for the slurry feed system.

Distributed Sensor Coordination for Advanced Energy Systems  

SciTech Connect

The ability to collect key system level information is critical to the safe, efficient and reli- able operation of advanced energy systems. With recent advances in sensor development, it is now possible to push some level of decision making directly to computationally sophisticated sensors, rather than wait for data to arrive to a massive centralized location before a decision is made. This type of approach relies on networked sensors (called agents from here on) to actively collect and process data, and provide key control deci- sions to significantly improve both the quality/relevance of the collected data and the as- sociating decision making. The technological bottlenecks for such sensor networks stem from a lack of mathematics and algorithms to manage the systems, rather than difficulties associated with building and deploying them. Indeed, traditional sensor coordination strategies do not provide adequate solutions for this problem. Passive data collection methods (e.g., large sensor webs) can scale to large systems, but are generally not suited to highly dynamic environments, such as ad- vanced energy systems, where crucial decisions may need to be reached quickly and lo- cally. Approaches based on local decisions on the other hand cannot guarantee that each agent performing its task (maximize an agent objective) will lead to good network wide solution (maximize a network objective) without invoking cumbersome coordination rou- tines. There is currently a lack of algorithms that will enable self-organization and blend the efficiency of local decision making with the system level guarantees of global decision making, particularly when the systems operate in dynamic and stochastic environments. In this work we addressed this critical gap and provided a comprehensive solution to the problem of sensor coordination to ensure the safe, reliable, and robust operation of advanced energy systems. The differentiating aspect of the proposed work is in shift- ing the focus towards what to observe rather than how to observe in large sensor networks, allowing the agents to actively determine both the structure of the network and the relevance of the information they are seeking to collect. In addition to providing an implicit coordination mechanism, this approach allows the system to be reconfigured in response to changing needs (e.g., sudden external events requiring new responses) or changing sensor network characteristics (e.g., sudden changes to plant condition). Outcome Summary: All milestones associated with this project have been completed. In particular, private sensor objective functions were developed which are aligned with the global objective function, sensor effectiveness has been improved by using sensor teams, system efficiency has been improved by 30% using difference evaluation func- tions, we have demonstrated system reconfigurability for 20% changes in system con- ditions, we have demonstrated extreme scalability of our proposed algorithm, we have demonstrated that sensor networks can overcome disruptions of up to 20% in network conditions, and have demonstrated system reconfigurability to 20% changes in system conditions in hardware-based simulations. This final report summarizes how each of these milestones was achieved, and gives insight into future research possibilities past the work which has been completed. The following publications support these milestones [6, 8, 9, 10, 16, 18, 19].

A distributed data storage and processing framework for next-generation residential distribution systems  

Science Journals Connector (OSTI)

Abstract As the number of smart meters/sensors increases to more than hundreds of thousands, it is rather intuitive that the state-of-the-art centralized information processing architecture will no longer be sustainable under such a big data explosion. Hence, an innovative data management system is urgently needed to facilitate the real-world deployment of a future residential distribution system. In this paper, we investigate a radically different approach through distributed software agents to translate the legacy centralized data storage and processing scheme to a completely distributed cyber-physical architecture. We further substantiate the proposed distributed data storage and processing framework on a proof-of-concept testbed using a cluster of low-cost and credit-card-sized single-board computers. Finally, we evaluate the proposed distributed framework and proof-of-concept testbed with a comprehensive set of performance measures.

Residential hot water distribution systems: Roundtablesession  

SciTech Connect

Residential building practice currently ignores the lossesof energy and water caused by the poor design of hot water systems. Theselosses include: combustion and standby losses from water heaters, thewaste of water (and energy) while waiting for hot water to get to thepoint of use; the wasted heat as water cools down in the distributionsystem after a draw; heat losses from recirculation systems and thediscarded warmth of waste water as it runs down the drain. Severaltechnologies are available that save energy (and water) by reducing theselosses or by passively recovering heat from wastewater streams and othersources. Energy savings from some individual technologies are reported tobe as much as 30 percent. Savings calculations of prototype systemsincluding bundles of technologies have been reported above 50 percent.This roundtable session will describe the current practices, summarizethe results of past and ongoing studies, discuss ways to think about hotwater system efficiency, and point to areas of future study. We will alsorecommend further steps to reduce unnecessary losses from hot waterdistribution systems.

Towards understanding the benefits and challenges of Smart/Micro-Grid for electricity supply system in Nigeria  

Science Journals Connector (OSTI)

Abstract The poor state of electricity supply system in Nigeria is threatening the welfare and security of life and properties of millions of individuals with adverse economic consequences for the country. The inadequacy of the national grid, especially the inability of the electricity generation capacity to match increasing demand in the country has led to increasing agitation for increased penetration of renewable energy sources (RESs) into the electricity supply mix. While great attention has been focused on the potential of \\{RESs\\} for electricity generation in the country, little or no attention has been given to the application of Smart/Micro-Grid (SM-G) technologies to the ageing Nigeria grid infrastructures and electrification of the rural areas. The aim of this paper is to bring into focus the benefits and challenges of enabling SM-G in the electricity supply system in Nigeria. SM-G will bring benefits to the electricity stakeholders in form of improvements in reliability, efficiency, economics, environment, security and safety. The paper gives an overview and reviews the current state of the electricity supply system in the country. It discusses the SM-G concepts and associated technologies, and highlights how they can help address the electricity problems in the country. The challenges of applying these concepts in Nigeria context are also discussed. Enabling SM-G in the country will not only lead to improvement in the quality, efficiency and reliability of the electricity grid, but also promote the provision of electricity supply to the remote rural areas using RESs.

This report describes the development of the design of an advanced dry feed system that was carried out under Task 4.0 of Cooperative Agreement DE-FE0007902 with the US DOE, Scoping Studies to Evaluate the Benefits of an Advanced Dry Feed System on the use of Low- Rank Coal. The resulting design will be used for the advanced technology IGCC case with 90% carbon capture for sequestration to be developed under Task 5.0 of the same agreement. The scope of work covered coal preparation and feeding up through the gasifier injector. Subcomponents have been broken down into feed preparation (including grinding and drying), low pressure conveyance, pressurization, high pressure conveyance, and injection. Pressurization of the coal feed is done using Posimetric1 Feeders sized for the application. In addition, a secondary feed system is described for preparing and feeding slag additive and recycle fines to the gasifier injector. This report includes information on the basis for the design, requirements for down selection of the key technologies used, the down selection methodology and the final, down selected design for the Posimetric Feed System, or PFS.

Advanced islanding detection utilized in distribution systems with DFIG  

Science Journals Connector (OSTI)

Abstract The penetration of distributed generation (DG) in electrical power systems is rapidly increasing these days and more attention is drawn to maintain a healthy distribution system. Islanding operation of \\{DGs\\} is one of the biggest challenges to the distribution system stability. Fast and accurate islanding detection can avoid the possibility of damages to the \\{DGs\\} when they are un-intentionally reconnected to the grid and also provide useful information to the protection and automation design of the stand alone operated system. Rate of change of frequency (ROCOF) method is one of the most commonly employed anti-islanding protection techniques, it offers fast detection and easy implementation. However, it is often easily affected by the system disturbance and might not able to detect the islanding situation if the power imbalance between the DG and the load is small. This paper investigates an inter-lock method which can improve the performance of rate of change of frequency (ROCOF) by applying system impedance estimation. It was found that this new method can help in verifying the ROCOF relay islanding detection and avoiding false operations of ROCOF in a grid connected distribution system which has large load variations. The proposed method was verified using the experimental testing results derived from both an experimental testing model which includes an 8kW Double Feed Induction Generator (DFIG) and a 9MW DFIG simulation system.

Performance of thermal distribution systems in large commercial buildings Performance of thermal distribution systems in large commercial buildings Title Performance of thermal distribution systems in large commercial buildings Publication Type Journal Article LBNL Report Number LBNL-44331 Year of Publication 2002 Authors Xu, Tengfang T., François Rémi Carrié, Darryl J. Dickerhoff, William J. Fisk, Jennifer A. McWilliams, Duo Wang, and Mark P. Modera Journal Energy and Buildings Volume 34 Start Page Chapter Pagination 215-226 Abstract This paper presents major findings of a field study on the performance of five thermal distribution systems in four large commercial buildings. The five systems studied are typical single-duct or dual-duct constant air volume (CAV) systems and variable air volume (VAV) systems, each of which serves an office building or a retail building with floor area over 2,000 m2. The air leakage from ducts are reported in terms of effective leakage area (ELA) at 25 Pa reference pressure, the ASHRAE-defined duct leakage class, and air leakage ratios. The specific ELAs ranged from 0.7 to 12.9 cm2 per m2 of duct surface area, and from 0.1 to 7.7 cm2 per square meter of floor area served. The leakage classes ranged from 34 to 757 for the five systems and systems sections tested. The air leakage ratios are estimated to be up to one-third of the fan- supplied airflow in the constant-air-volume systems. The specific ELAs and leakage classes indicate that air leakage in large commercial duct systems varies significantly from system to system, and from system section to system section even within the same thermal distribution system. The duct systems measured are much leakier than the ductwork specified as "unsealed ducts" by ASHRAE. Energy losses from supply ducts by conduction (including convection and radiation) are found to be significant, on the scale similar to the losses induced by air leakage in the duct systems. The energy losses induced by leakage and conduction suggest that there are significant energy-savings potentials from duct-sealing and insulation practice in large commercial buildings

A Simulation Model for Evaluating Distributed Systems Dependability  

E-Print Network (OSTI)

In this paper we present a new simulation model designed to evaluate the dependability in distributed systems. This model extends the MONARC simulation model with new capabilities for capturing reliability, safety, availability, security, and maintainability requirements. The model has been implemented as an extension of the multithreaded, process oriented simulator MONARC, which allows the realistic simulation of a wide-range of distributed system technologies, with respect to their specific components and characteristics. The extended simulation model includes the necessary components to inject various failure events, and provides the mechanisms to evaluate different strategies for replication, redundancy procedures, and security enforcement mechanisms, as well. The results obtained in simulation experiments presented in this paper probe that the use of discrete-event simulators, such as MONARC, in the design and development of distributed systems is appealing due to their efficiency and scalability.

Global Environmental Benefits Global Environmental Benefits Gasification Systems Global Environmental Benefits Environmental performance for future energy production systems is a much greater factor as emission standards tighten in the United States and worldwide. The outstanding environmental performance of gasification systems makes it an excellent technology for the clean production of electricity and other products. In addition, the reduction of CO2 emissions is one of the major challenges facing industry in response to global climate change. Other countries with coal reserves might potentially import technologies developed in the United States to enable low-cost gasification with carbon capture and EOR or sequestration. Not only will this benefit the U.S. gasification technology industry, but it will also result in a global environmental benefit through more affordable control of greenhouse gases (GHGs). See the U.S. Environmental Protection Agency (EPA) link below for a summary of the impact of fossil fuels without carbon capture on CO2 emissions, on the GHG contributions of different countries, and of the projected impact of developing countries to 2030:

Onsite Distributed Generation Systems For Laboratories, Laboratories for the 21st Century: Best Practices (Brochure)  

SciTech Connect

This guide provides general information on implementing onsite distributed generation systems in laboratory environments. Specific technology applications, general performance information, and cost data are provided to educate and encourage laboratory energy managers to consider onsite power generation or combined heat and power (CHP) systems for their facilities. After conducting an initial screening, energy managers are encouraged to conduct a detailed feasibility study with actual cost and performance data for technologies that look promising. Onsite distributed generation systems are small, modular, decentralized, grid-connected, or off-grid energy systems. These systems are located at or near the place where the energy is used. These systems are also known as distributed energy or distributed power systems. DG technologies are generally considered those that produce less than 20 megawatts (MW) of power. A number of technologies can be applied as effective onsite DG systems, including: (1) Diesel, natural gas, and dual-fuel reciprocating engines; (2) Combustion turbines and steam turbines; (3) Fuel cells; (4) Biomass heating; (5) Biomass combined heat and power; (6) Photovoltaics; and (7) Wind turbines. These systems can provide a number of potential benefits to an individual laboratory facility or campus, including: (1) High-quality, reliable, and potentially dispatchable power; (2) Low-cost energy and long-term utility cost assurance, especially where electricity and/or fuel costs are high; (3) Significantly reduced greenhouse gas (GHG) emissions. Typical CHP plants reduce onsite GHG by 40 to 60 percent; (4) Peak demand shaving where demand costs are high; (5) CHP where thermal energy can be used in addition to electricity; (6) The ability to meet standby power needs, especially where utility-supplied power is interrupted frequently or for long periods and where standby power is required for safety or emergencies; and (7) Use for standalone or off-grid systems where extending the grid is too expensive or impractical. Because they are installed close to the load, DG systems avoid some of the disadvantages of large, central power plants, such as transmission and distribution losses over long electric lines.

Commercial thermal distribution systems, Final report for CIEE/CEC  

SciTech Connect

According to the California Energy Commission (CEC 1998a), California commercial buildings account for 35% of statewide electricity consumption, and 16% of statewide gas consumption. Space conditioning accounts for roughly 16,000 GWh of electricity and 800 million therms of natural gas annually, and the vast majority of this space conditioning energy passes through thermal distribution systems in these buildings. In addition, 8600 GWh per year is consumed by fans and pumps in commercial buildings, most of which is used to move the thermal energy through these systems. Research work at Lawrence Berkeley National Laboratory (LBNL) has been ongoing over the past five years to investigate the energy efficiency of these thermal distribution systems, and to explore possibilities for improving that energy efficiency. Based upon that work, annual savings estimates of 1 kWh/ft{sup 2} for light commercial buildings, and 1-2 kWh/ft{sup 2} in large commercial buildings have been developed for the particular aspects of thermal distribution system performance being addressed by this project. Those savings estimates, combined with a distribution of the building stock based upon an extensive stock characterization study (Modera et al. 1999a), and technical penetration estimates, translate into statewide saving potentials of 2000 GWh/year and 75 million thermal/year, as well as an electricity peak reduction potential of 0.7 GW. The overall goal of this research program is to provide new technology and application knowledge that will allow the design, construction, and energy services industries to reduce the energy waste associated with thermal distribution systems in California commercial buildings. The specific goals of the LBNL efforts over the past year were: (1) to advance the state of knowledge about system performance and energy losses in commercial-building thermal distribution systems; (2) to evaluate the potential of reducing thermal losses through duct sealing, duct insulation, and improved equipment sizing; and (3) to develop and evaluate innovative techniques applicable to large buildings for sealing ducts and encapsulating internal duct insulation. In the UCB fan project, the goals were: (1) to develop a protocol for testing, analyzing and diagnosing problems in large commercial building built-up air handling systems, and (2) to develop low-cost measurement techniques to improve short term monitoring practices. To meet our stated goals and objectives, this project: (1) continued to investigate and characterize the performance of thermal distribution systems in commercial buildings; (2) performed energy analyses and evaluation for duct-performance improvements for both small and large commercial buildings; (3) developed aerosol injection technologies for both duct sealing and liner encapsulation in commercial buildings; and (4) designed energy-related diagnostic protocols based on short term measurement and used a benchmarking database to compare subject systems with other measured systems for certain performance metrics. This year's efforts consisted of the following distinct tasks: performing characterization measurements for five light commercial building systems and five large-commercial-building systems; analyzing the potential for including duct performance in California's Energy Efficiency Standards for Residential and Non-Residential Buildings (Title 24), including performing energy and equipment sizing analyses of air distribution systems using DOE 2.1E for non-residential buildings; conducting laboratory experiments, field experiments, and modeling of new aerosol injection technologies concepts for sealing and coating, including field testing aerosol-based sealing in two large commercial buildings; improving low-cost fan monitoring techniques measurements, and disseminating fan tools by working with energy practitioners directly where possible and publishing the results of this research and the tools developed on a web-site.

Implementation of non-intrusive energy saving estimation for Volt/VAr control of smart distribution system  

Science Journals Connector (OSTI)

Abstract There has been a growing interest among power distribution utilities to explore smart grid technologies to improve the operational efficiency and reliability. As electricity distribution grid is evolving to become smart, energy demand reduction is one of the goals for the distribution utilities. In order to obtain this goal, utilities need to commit significant financial resources. Therefore, it became important to assess the benefit of new technologies such as Volt/VAr control (VVC). To compute the energy savings due to VVC implementation, existing algorithms are intrusive, and generally require altering the distribution system control settings and operating points, which is undesirable for system operator. On the other hand, these may require large amount of historical data. In this paper, implementation of a new non-intrusive energy saving estimation algorithm has been presented for integrated Volt/VAr control by Avista Utilities in Northwest USA. Developed algorithm utilizes measurements from smart distribution system. Develop algorithm allows studying the energy saving in long term as it requires no change in control settings of actual distribution system. Satisfactory results have been obtained and validated against field data from experiments on real feeders by Avista Utilities.

The Fermilab CMTF cryogenic distribution remote control system  

SciTech Connect

The Cryomodule Test Facility (CMTF) is able to provide the necessary test bed for measuring the performance of Superconducting Radio Frequency (SRF) cavities in a cryomodule (CM). The CMTF have seven 300 KW screw compressors, two liquid helium refrigerators, and two Cryomodule Test Stands (CMTS). CMTS1 is designed for 1.3 GHz cryomodule operating in a pulsed mode (PM) and CMTS2 is for cryomodule operating in Half-Wave (HW) and Continuous Wave (CW) mode. Based on the design requirement, each subsystem has to be far away from each other and be placed in distant locations. Therefore choosing Siemens Process Control System 7-400, DL205 PLC, Synoptic and Fermilab ACNET are the ideal choices for CMTF cryogenic distribution real-time remote control system. This paper presents a method which has been successfully used by many Fermilab distribution cryogenic real-time remote control systems.

Science Journals Connector (OSTI)

In this paper quantitative impact of automatic switches on the reliability of power distribution systems is studied. Based on the characteristics of the studied system's topology, the reliability model is developed for the implementation of Monte Carlo simulation. Reliability indices on each load have been computed to obtain an overall reliability assessment of the system, and the sensitivity of the reliability indices to the location of automatic switches is also studied. Simulation results are used to illustrate the validity of the approach and are compared with the historical reliability records.

Interconnecting PV on New York City's Secondary Network Distribution System  

SciTech Connect

The U.S. Department of Energy (DOE) has teamed with cities across the country through the Solar America Cities (SAC) partnership program to help reduce barriers and accelerate implementation of solar energy. The New York City SAC team is a partnership between the City University of New York (CUNY), the New York City Mayor s Office of Long-term Planning and Sustainability, and the New York City Economic Development Corporation (NYCEDC).The New York City SAC team is working with DOE s National Renewable Energy Laboratory (NREL) and Con Edison, the local utility, to develop a roadmap for photovoltaic (PV) installations in the five boroughs. The city set a goal to increase its installed PV capacity from1.1 MW in 2005 to 8.1 MW by 2015 (the maximum allowed in 2005). A key barrier to reaching this goal, however, is the complexity of the interconnection process with the local utility. Unique challenges are associated with connecting distributed PV systems to secondary network distribution systems (simplified to ???¢????????networks???¢??????? in this report). Although most areas of the country use simpler radial distribution systems to distribute electricity, larger metropolitan areas like New York City typically use networks to increase reliability in large load centers. Unlike the radial distribution system, where each customer receives power through a single line, a network uses a grid of interconnected lines to deliver power to each customer through several parallel circuits and sources. This redundancy improves reliability, but it also requires more complicated coordination and protection schemes that can be disrupted by energy exported from distributed PV systems. Currently, Con Edison studies each potential PV system in New York City to evaluate the system s impact on the network, but this is time consuming for utility engineers and may delay the customer s project or add cost for larger installations. City leaders would like to streamline this process to facilitate faster, simpler, and less expensive distributed PV system interconnections. To assess ways to improve the interconnection process, NREL conducted a four-part study with support from DOE. The NREL team then compiled the final reports from each study into this report. In Section 1???¢????????PV Deployment Analysis for New York City???¢????????we analyze the technical potential for rooftop PV systems in the city. This analysis evaluates potential PV power production in ten Con Edison networks of various locations and building densities (ranging from high density apartments to lower density single family homes). Next, we compare the potential power production to network loads to determine where and when PV generation is most likely to exceed network load and disrupt network protection schemes. The results of this analysis may assist Con Edison in evaluating future PV interconnection applications and in planning future network protection system upgrades. This analysis may also assist other utilities interconnecting PV systems to networks by defining a method for assessing the technical potential of PV in the network and its impact on network loads. Section 2???¢????????A Briefing for Policy Makers on Connecting PV to a Network Grid???¢????????presents an overview intended for nontechnical stakeholders. This section describes the issues associated with interconnecting PV systems to networks, along with possible solutions.

The design of a distributed image processing and dissemination system  

SciTech Connect

The design and implementation of a distributed image processing and dissemination system was undertaken and accomplished as part of a prototype communication and intelligence (CI) system, the contingency support system (CSS), which is intended to support contingency operations of the Tactical Air Command. The system consists of six (6) Sun 3/180C workstations with integrated ITEX image processors and three (3) 3/50 diskless workstations located at four (4) system nodes (INEL, base, and mobiles). All 3/180C workstations are capable of image system server functions where as the 3/50s are image system clients only. Distribution is accomplished via both local and wide area networks using standard Defense Data Network (DDN) protocols (i.e., TCP/IP, et al.) and Defense Satellite Communication Systems (DSCS) compatible SHF Transportable Satellite Earth Terminals (TSET). Image applications utilize Sun's Remote Procedure Call (RPC) to facilitate the image system client and server relationships. The system provides functions to acquire, display, annotate, process, transfer, and manage images via an icon, panel, and menu oriented Sunview{trademark} based user interface. Image spatial resolution is 512 {times} 480 with 8-bits/pixel black and white and 12/24 bits/pixel color depending on system configuration. Compression is used during various image display and transmission functions to reduce the dynamic range of image data of 12/6/3/2 bits/pixel depending on the application. Image acquisition is accomplished in real-time or near-real-time by special purpose Itex image hardware. As a result all image displays are highly interactive with attention given to subsecond response time. 3 refs., 7 figs.

Parallel Breadth-First Search on Distributed Memory Systems  

SciTech Connect

Data-intensive, graph-based computations are pervasive in several scientific applications, and are known to to be quite challenging to implement on distributed memory systems. In this work, we explore the design space of parallel algorithms for Breadth-First Search (BFS), a key subroutine in several graph algorithms. We present two highly-tuned par- allel approaches for BFS on large parallel systems: a level-synchronous strategy that relies on a simple vertex-based partitioning of the graph, and a two-dimensional sparse matrix- partitioning-based approach that mitigates parallel commu- nication overhead. For both approaches, we also present hybrid versions with intra-node multithreading. Our novel hybrid two-dimensional algorithm reduces communication times by up to a factor of 3.5, relative to a common vertex based approach. Our experimental study identifies execu- tion regimes in which these approaches will be competitive, and we demonstrate extremely high performance on lead- ing distributed-memory parallel systems. For instance, for a 40,000-core parallel execution on Hopper, an AMD Magny- Cours based system, we achieve a BFS performance rate of 17.8 billion edge visits per second on an undirected graph of 4.3 billion vertices and 68.7 billion edges with skewed degree distribution.

Depositional systems distribution of the lower Oligocene Vicksburg Formation, TX  

SciTech Connect

The lower Oligocene Vicksburg Formation of Texas is situated between the upper Eocene Jackson Group and the upper Oligocene Frio Formation. The paleogeography of the Texas Gulf coastal plain during the early Oligocene is typical of a progradational passive continental margin. However, a detailed regional depositional systems analysis of stratigraphic units, such as the Vicksburg, within a mature petroleum basin can yield results beneficial in both exploration and development. Stratigraphic plays are determined from the distribution of depositional systems, and reservoir characteristics are heavily influenced by conditions of sedimentation. Two primary depocenters (and exploration fairways) of the Texas Vicksburg were the Houston Embayment and the Rio Grande Embayment; they were separated by a deep-rooted structural nose in central Texas: the San Marcos arch. Within the embayments, deltaic depositional systems merged along strike with barrier/strand plain systems. Updip, fluvial systems traversed coastal plain units. On the seaward edge of the paralic systems, sand and mud deposits prograded across, and built up over, the relict Jackson shelf and shelf margin. Contemporaneous growth faulting controlled deltaic depositional patterns in the Rio Grande Embayment and, to a lesser degree, in the Houston Embayment. A barrier/strand plain system within an interdeltaic coastal bight extended across the northern flank of the San Marcos arch. Several minor wave-dominated delta complexes were interspersed within this regional setting. The southern flank of the arch was influenced by the fluvial systems of the Rio Grande Embayment that established another wave-dominated delta. Deposition of the Vicksburg progradational paralic sediments was initiated seaward of the Jackson coastal position. A brief, minor transgression interrupted the progradational pattern during middle Vicksburg deposition.

Differential evolution applied for reliability optimization of radial distribution systems  

Science Journals Connector (OSTI)

This paper describes a methodology for reliability enhancement of radial distribution system by determining optimal values of repair times and failure rates of each section. Penalty cost functions have been constructed as function of failure rates and repair times. Constraints on customer and energy based indices, i.e. SAIFI, SAIDI, CAIDI and AENS have been considered. The problem has been decomposed in two stages. One stage determines the optimum failure rates and second stage optimizes repair times satisfying constraints. A population based approach, i.e. differential evolution (DE) has been used as optimization technique. The algorithm has been implemented on a sample test system. Results obtained have been compared with those obtained using particle swarm optimization (PSO) and co-ordinated aggregation based particle swarm optimization techniques (CAPSO).

SciTech Connect

To prevent voltage decrease of distribution systems, the principle and fundamental characteristics of a solid-state current limiter using GTO thyristors were investigated. Basic components of the apparatus were a fast solid-state switch and a current limiting impedance of low resistance in parallel with the switch. Experimental results of the test current limiter showed the fault current was limited successfully, regardless of DC component size. The time from detection of fault current was limited successfully, regardless of DC component size. The time from detection of fault occurrence to interruption of the fault current by the solid-state switch was 40 [mu]s. This time was very short in comparison with that before the fault current reached a large value. Thermal rise of the solid-state switch for conduction was solved by a self-cooling apparatus using a non-combustible cooling liquid. The results indicated that the solid-state current limiter was a valuable protecting device for high fault current distribution systems.

A new HBMO algorithm for multiobjective daily Volt/Var control in distribution systems considering Distributed Generators  

Science Journals Connector (OSTI)

In recent years, Distributed Generators (DGs) connected to the distribution network have received increasing attention. The connection of enormous \\{DGs\\} into existing distribution network changes the operation of distribution systems. Because of the small X/R ratio and radial structure of distribution systems, \\{DGs\\} affect the daily Volt/Var control. This paper presents a new algorithm for multiobjective daily Volt/Var control in distribution systems including Distributed Generators (DGs). The objectives are costs of energy generation by \\{DGs\\} and distribution companies, electrical energy losses and the voltage deviations for the next day. A new optimization algorithm based on a Chaotic Improved Honey Bee Mating Optimization (CIHBMO) is proposed to determine the active power values of DGs, reactive power values of capacitors and tap positions of transformers for the next day. Since objectives are not the same, a fuzzy system is used to calculate the best solution. The plausibility of the proposed algorithm is demonstrated and its performance is compared with other methods on a 69-bus distribution feeder. Simulation results illustrate that the proposed algorithm has better outperforms the other algorithms.

Installation of PV systems in GreeceReliability improvement in the transmission and distribution system  

Science Journals Connector (OSTI)

Photovoltaic (PV) power systems are becoming one of the most developing investment areas in the field of Renewable Energy Sources (RES). A statement of the status quo of PV power systems in Greece, and their contribution towards the improvement of power system reliability, is the scope of the present paper. Siting and installation of PV power systems is performed according to a recent Greek law, along with environmental and geographical constraints. Meteorological data are computed, formulated and imported to appropriate software in order to simulate the PV units and generate their power output. Data for unserved loads, resulting from load shedding during peak hours, are compared to the above estimated power production. Assuming that a proportion of the eventually unsupplied power could be provided by the accessed power generation of the PV units, the reliability of both transmission and distribution system is improved. The impact on the transmission system is shown by an improvement of LOLP and LOEP indices, whereas peak shaving for the Interconnected Greek Transmission System (IGTS) is also illustrated. For the distribution system the impact is quantified using the distribution system reliability indices SAIDI, SAIFI, and CAIDI. Finally, the resulting improvement is also expressed in financial terms.

Distributed digital real-time control system for TCV tokamak  

Science Journals Connector (OSTI)

Abstract A new digital feedback control system (named the SCD Systme de Contrle Distribu) has been developed, integrated and used successfully to control TCV (Tokamak Configuration Variable) plasmas. The system is designed to be modular, distributed, and scalable, accommodating hundreds of diagnostic inputs and actuator outputs. With many more inputs and outputs available than previously possible, it offers the possibility to design advanced control algorithms with better knowledge of the plasma state and to coherently control all TCV actuators, including poloidal field (PF) coils, gas valves, the gyrotron powers and launcher angles of the electron cyclotron heating and current drive system (ECRH/ECCD) together with diagnostic triggering signals. The system consists of multiple nodes; each is a customised Linux desktop or embedded PC which may have local ADC and DAC cards. Each node is also connected to a memory network (reflective memory) providing a reliable, deterministic method of sharing memory between all nodes. Control algorithms are programmed as block diagrams in Matlab-Simulink providing a powerful environment for modelling and control design. The C code is generated automatically from the Simulink block diagram and compiled, with the Simulink Embedded Coder (SEC, formerly Real-Time Workshop Embedded Coder), into a Linux shared library (.so file) and distributed to target nodes in the discharge preparation phase. During the TCV discharge, an application on each node is executed that dynamically loads the shared library at runtime. In order to obtain reliable and reproducible real time execution of the algorithm, all interrupts to the CPU on each node are suspended just before firing the shot and re-enabled afterwards. Since installation, the new digital control system has been used for a multitude of plasma control applications, ranging from basic experiments of coil current and density control to advanced experiments of MHD (magnetohydrodynamics) and plasma profile control, as well as real-time plasma transport simulations. Recently, a real-time version of a plasma equilibrium reconstruction code was developed and implemented, providing the future possibility to control the plasma shape and profiles directly during the discharge evolution. This paper presents the architecture of the new control system, its integration into the TCV plant and a sample of control applications used for TCV plasma discharges.

Log Summarization and Anomaly Detection for TroubleshootingDistributed Systems  

SciTech Connect

Today's system monitoring tools are capable of detectingsystem failures such as host failures, OS errors, and network partitionsin near-real time. Unfortunately, the same cannot yet be said of theend-to-end distributed softwarestack. Any given action, for example,reliably transferring a directory of files, can involve a wide range ofcomplex and interrelated actions across multiple pieces of software:checking user certificates and permissions, getting details for allfiles, performing third-party transfers, understanding re-try policydecisions, etc. We present an infrastructure for troubleshooting complexmiddleware, a general purpose technique for configurable logsummarization, and an anomaly detection technique that works in near-realtime on running Grid middleware. We present results gathered using thisinfrastructure from instrumented Grid middleware and applications runningon the Emulab testbed. From these results, we analyze the effectivenessof several algorithms at accurately detecting a variety of performanceanomalies.

ALBL: an adaptive load balancing algorithm for distributed web systems  

Science Journals Connector (OSTI)

This paper presents an adaptive load balancing algorithm (ALBL) for cluster-based web systems. The balancing policy is based on two criteria: HTTP process time and network delay. The former describes web server ability to process a forthcoming request, while the latter tries to estimate network conditions. Periodic criteria calculations are performed by agents at the web switch and the weight estimation process is transparent to web servers enhancing therefore distributed system's scalability. We put to test our implementation against known blind selection balancing algorithms used at web-farms such as: Round Robin, stateful ones such as Least Connections and adaptive ones such as Least Load. We also put to test performance and scalability of previous algorithms. From our testbed scenario results we show that ALBL algorithm outperforms stateless and stateful algorithms and also presents significant performance gains towards adaptive algorithms. We also show that our algorithm scales well as the number of balancing servers and web cluster's requests rate increases. We also pinpoint ALBL algorithm ability to predict network conditions and web servers load without the use of feedback information obtained by web servers but frequent service and network probes towards web servers issued by the web switch.

Cybersecurity through Real-Time Distributed Control Systems  

SciTech Connect

Critical infrastructure sites and facilities are becoming increasingly dependent on interconnected physical and cyber-based real-time distributed control systems (RTDCSs). A mounting cybersecurity threat results from the nature of these ubiquitous and sometimes unrestrained communications interconnections. Much work is under way in numerous organizations to characterize the cyber threat, determine means to minimize risk, and develop mitigation strategies to address potential consequences. While it seems natural that a simple application of cyber-protection methods derived from corporate business information technology (IT) domain would lead to an acceptable solution, the reality is that the characteristics of RTDCSs make many of those methods inadequate and unsatisfactory or even harmful. A solution lies in developing a defense-in-depth approach that ranges from protection at communications interconnect levels ultimately to the control system s functional characteristics that are designed to maintain control in the face of malicious intrusion. This paper summarizes the nature of RTDCSs from a cybersecurity perspec tive and discusses issues, vulnerabilities, candidate mitigation approaches, and metrics.

Linac cryogenic distribution system maintenance and upgrades at JLab  

SciTech Connect

The Central Helium Liquefier (CHL) distribution system to the CEBAF and FEL linacs at Jefferson Lab (JLab) experienced a planned warm up during the late summer and fall of 2012 for the first time after its commissioning in 1991. Various maintenance and modifications were performed to support high beam availability to the experimental users, meet 10 CFR 851 requirements for pressure systems, address operational issues, and prepare the cryogenic interfaces for the high-gradient cryomodules needed for the 12 GeV upgrade. Cryogenic maintenance and installation work had to be coordinated with other activities in the linacs and compete for manpower from other department installation activities. With less than a quarter of the gas storage capacity available to handle the boil-off from the more than 40 cryomodules, 35,000 Nm{sup 3} of helium was re-liquefied and shipped to a vendor via a liquid tanker trailer. Nearly 200 u-tubes had to be removed and stored while seals were replaced on related equipment such as vacuum pump outs, bayonet isolation and process valves.

Low-Cost Hydrogen Distributed Production System Development  

SciTech Connect

H{sub 2}Gen, with the support of the Department of Energy, successfully designed, built and field-tested two steam methane reformers with 578 kg/day capacity, which has now become a standard commercial product serving customers in the specialty metals and PV manufacturing businesses. We demonstrated that this reformer/PSA system, when combined with compression, storage and dispensing (CSD) equipment could produce hydrogen that is already cost-competitive with gasoline per mile driven in a conventional (non-hybrid) vehicle. We further showed that mass producing this 578 kg/day system in quantities of just 100 units would reduce hydrogen cost per mile approximately 13% below the cost of untaxed gasoline per mile used in a hybrid electric vehicle. If mass produced in quantities of 500 units, hydrogen cost per mile in a FCEV would be 20% below the cost of untaxed gasoline in an HEV in the 2015-2020 time period using EIA fuel cost projections for natural gas and untaxed gasoline, and 45% below the cost of untaxed gasoline in a conventional car. This 20% to 45% reduction in fuel cost per mile would accrue even though hydrogen from this 578 kg/day system would cost approximately $4.14/kg, well above the DOE hydrogen cost targets of $2.50/kg by 2010 and $2.00/kg by 2015. We also estimated the cost of a larger, 1,500 kg/day SMR/PSA fueling system based on engineering cost scaling factors derived from the two H{sub 2}Gen products, a commercial 115 kg/day system and the 578 kg/day system developed under this DOE contract. This proposed system could support 200 to 250 cars per day, similar to a medium gasoline station. We estimate that the cost per mile from this larger 1,500 kg/day hydrogen fueling system would be 26% to 40% below the cost per mile of untaxed gasoline in an HEV and ICV respectively, even without any mass production cost reductions. In quantities of 500 units, we are projecting per mile cost reductions between 45% (vs. HEVs) and 62% (vs ICVs), with hydrogen costing approximately $2.87/kg, still above the DOE's 2010 $2.50/kg target. We also began laboratory testing of reforming ethanol, which we showed is currently the least expensive approach to making renewable hydrogen. Extended testing of neat ethanol in micro-reactors was successful, and we also were able to reform E-85 acquired from a local fueling station for 2,700 hours, although some modifications were required to handle the 15% gasoline present in E-85. We began initial tests of a catalyst-coated wall reformer tube that showed some promise in reducing the propensity to coke with E-85. These coated-wall tests ran for 350 hours. Additional resources would be required to commercialize an ethanol reformer operating on E-85, but there is no market for such a product at this time, so this ethanol reformer project was moth-balled pending future government or industry support. The two main objectives of this project were: (1) to design, build and test a steam methane reformer and pressure swing adsorption system that, if scaled up and mass produced, could potentially meet the DOE 2015 cost and efficiency targets for on-site distributed hydrogen generation, and (2) to demonstrate the efficacy of a low-cost renewable hydrogen generation system based on reforming ethanol to hydrogen at the fueling station.

IMPACTS OF REFRIGERANTLINE LENGTH ON SYSTEM EFFICIENCY IN RESIDENTIAL HEATING AND COOLING SYSTEMS USING REFRIGERANT DISTRIBUTION.  

SciTech Connect

The effects on system efficiency of excess refrigerant line length are calculated for an idealized residential heating and cooling system. By excess line length is meant refrigerant tubing in excess of the 25 R provided for in standard equipment efficiency test methods. The purpose of the calculation is to provide input for a proposed method for evaluating refrigerant distribution system efficiency. A refrigerant distribution system uses refrigerant (instead of ducts or pipes) to carry heat and/or cooling effect from the equipment to the spaces in the building in which it is used. Such systems would include so-called mini-splits as well as more conventional split systems that for one reason or another have the indoor and outdoor coils separated by more than 25 ft. This report performs first-order calculations of the effects on system efficiency, in both the heating and cooling modes, of pressure drops within the refrigerant lines and of heat transfer between the refrigerant lines and the space surrounding them.

Distributed generation capabilities of the national energy modeling system  

SciTech Connect

This report describes Berkeley Lab's exploration of how the National Energy Modeling System (NEMS) models distributed generation (DG) and presents possible approaches for improving how DG is modeled. The on-site electric generation capability has been available since the AEO2000 version of NEMS. Berkeley Lab has previously completed research on distributed energy resources (DER) adoption at individual sites and has developed a DER Customer Adoption Model called DER-CAM. Given interest in this area, Berkeley Lab set out to understand how NEMS models small-scale on-site generation to assess how adequately DG is treated in NEMS, and to propose improvements or alternatives. The goal is to determine how well NEMS models the factors influencing DG adoption and to consider alternatives to the current approach. Most small-scale DG adoption takes place in the residential and commercial modules of NEMS. Investment in DG ultimately offsets purchases of electricity, which also eliminates the losses associated with transmission and distribution (T&D). If the DG technology that is chosen is photovoltaics (PV), NEMS assumes renewable energy consumption replaces the energy input to electric generators. If the DG technology is fuel consuming, consumption of fuel in the electric utility sector is replaced by residential or commercial fuel consumption. The waste heat generated from thermal technologies can be used to offset the water heating and space heating energy uses, but there is no thermally activated cooling capability. This study consists of a review of model documentation and a paper by EIA staff, a series of sensitivity runs performed by Berkeley Lab that exercise selected DG parameters in the AEO2002 version of NEMS, and a scoping effort of possible enhancements and alternatives to NEMS current DG capabilities. In general, the treatment of DG in NEMS is rudimentary. The penetration of DG is determined by an economic cash-flow analysis that determines adoption based on the n umber of years to a positive cash flow. Some important technologies, e.g. thermally activated cooling, are absent, and ceilings on DG adoption are determined by some what arbitrary caps on the number of buildings that can adopt DG. These caps are particularly severe for existing buildings, where the maximum penetration for any one technology is 0.25 percent. On the other hand, competition among technologies is not fully considered, and this may result in double-counting for certain applications. A series of sensitivity runs show greater penetration with net metering enhancements and aggressive tax credits and a more limited response to lowered DG technology costs. Discussion of alternatives to the current code is presented in Section 4. Alternatives or improvements to how DG is modeled in NEMS cover three basic areas: expanding on the existing total market for DG both by changing existing parameters in NEMS and by adding new capabilities, such as for missing technologies; enhancing the cash flow analysis but incorporating aspects of DG economics that are not currently represented, e.g. complex tariffs; and using an external geographic information system (GIS) driven analysis that can better and more intuitively identify niche markets.

Optimized Operation Strategies for PV Storages Systems Yield Limitations, Optimized Battery Configuration and the Benefit of a Perfect Forecast  

Science Journals Connector (OSTI)

Abstract Decreasing feed in tariffs and system prices combined with an increase of electricity tariffs supports the trend to install PV storage systems in private households. In the past years several investigations and field trials have shown, that these systems can increase the self consumption of PV-power and support the self sufficiency of private households [1], [2], [3], [4], [5], [6]. These systems also have a positive influence on the low-voltage grid [7], [8]. In recent years several investigations have been done to determine the optimal system configuration. They focus on the storage and PV generator size [9] or the applied storage technology [10]. In general, the mode of operation follows a simple regime: If PV production is larger than the actual consumption, PV power is stored. If the local consumption is higher than the actual PV production, stored power is used as long as available. Only slight modifications have been done, to map the price and efficiency effects of power electronics [11], [12]. Therefore, the results are limited to a single mode of operation. In this presentation, we derive a mathematical framework, which allows the calculation of the upper performance limit for a specific household and storage system, without any assumption on the operation strategy. We apply these analysis to a large set of German households and compare the upper performance limit for two different storage system designs: A system with relative short lifetime and small capacity on the one hand and another with a long lifetime and larger capacity

Impact of dispersed solar and wind systems on electric distribution planning and operation  

SciTech Connect

Small-scale dispersed solar photovoltaic and wind generation (DSW) will affect the generation, transmission, and distribution systems of an electric utility. This study examines the technical and economic impacts of dispersing DSW devices within the distribution system. Dispersed intermittent generation is included. Effects of DSW devices on capital investments, reliability, operating and maintenance costs, protection requirements, and communication and control requirements are examined. A DSW operation model is developed to help determine the dependable capacity of fluctuating solar photovoltaic and wind generation as part of the distribution planning process. Specific case studies using distribution system data and renewable resource data for Southern California Edison Company and Consumers Power Company are analyzed to gain insights into the effects of interconnecting DSW devices. The DSW devices were found to offer some distribution investment savings, depending on their availability during peak loads. For a summer-peaking utility, for example, dispersing photovoltaic systems is more likely to defer distribution capital investments than dispersing wind systems. Dispersing storage devices to increase DSW's dependable capacity for distribution systems needs is not economically attractive. Substation placement of DSW and storage devices is found to be more cost effective than feeder or customer placement. Examination of the effects of DSW on distribution system operation showed that small customer-owned DSW devices are not likely to disrupt present time-current distribution protection coordination. Present maintenance work procedures, are adequate to ensure workmen's safety. Regulating voltages within appropriate limits will become more complex with intermittent generation along the distribution feeders.

Integrated operation of electric vehicles and renewable generation in a smart distribution system  

Science Journals Connector (OSTI)

Abstract Distribution system complexity is increasing mainly due to technological innovation, renewable Distributed Generation (DG) and responsive loads. This complexity makes difficult the monitoring, control and operation of distribution networks for Distribution System Operators (DSOs). In order to cope with this complexity, a novel method for the integrated operational planning of a distribution system is presented in this paper. The method introduces the figure of the aggregator, conceived as an intermediate agent between end-users and DSOs. In the proposed method, energy and reserve scheduling is carried out by both aggregators and DSO. Moreover, Electric Vehicles (EVs) are considered as responsive loads that can participate in ancillary service programs by providing reserve to the system. The efficiency of the proposed method is evaluated on an 84-bus distribution test system. Simulation results show that the integrated scheduling of \\{EVs\\} and renewable generators can mitigate the negative effects related to the uncertainty of renewable generation.

A Queueing Based Scheduling Approach to Plug-In Electric Vehicle Dispatch in Distribution Systems  

E-Print Network (OSTI)

Large-scale integration of plug-in electric vehicles (PEV) in power systems can cause severe issues to the existing distribution system, such as branch congestions and significant voltage drops. As a consequence, smart charging strategies are crucial for the secure and reliable operation of the power system. This paper tries to achieve high penetration level of PEVs with the existing distribution system infrastructure by proposing a smart charging algorithm that can optimally utilize the distribution system capacity. Specifically, the paper proposes a max-weight PEV dispatch algorithm to control the PEV charging rates, subject to power system physical limits. The proposed max-weight PEV dispatch algorithm is proved to be throughput optimal under very mild assumptions on the stochastic dynamics in the system. This suggests that the costly distribution system infrastructure upgrade can be avoided, or failing that, at least successfully deferred. The proposed PEV dispatch algorithm is particularly attractive in ...

Design of an advanced electric power distribution systems using seeker optimization algorithm  

Science Journals Connector (OSTI)

Abstract The power distribution network design problem has a growing impact on secure and economical operation of distribution power system. This issue is well known as a non-linear, multi-modal and multi-objective optimization problem where global optimization techniques are required in order to avoid local minima. In this study, a new approach using seeker optimization algorithm (SOA) is proposed for distribution system planning problem with simultaneous placement of automatic reclosers (RAs), considering total system economic cost, overall system reliability, system power losses and voltage deviations as an objective functions. Normally, conventional power distribution systems (CPDS) are radial in nature and momentary fault in the system causes large area of the grid to be blacked out, which leads to huge load interruptions. Reliable distribution system minimize this effect by allowing faults to clear themselves by protection device operations such as automatic reclosers (RAs) and quickly restores the power through system reconfiguration by minimizing the loads affected. Thus, in order to prevent the system from momentary faults, simultaneous placement of \\{RAs\\} has been also done which leads to a design of an advanced power distribution system (APDS). Thus, the reliability issues are of major importance for effective planning of an APDS. For evaluation of reliability measure, the contingency-load-loss index (CLLI) is assessed in this paper, which is independent of the failure rate and fault repair duration of the feeder branches. The performance of the proposed algorithm is extensively assessed and comparisons are made with Particle Swarm Optimization (PSOs), Genetic Algorithm (GA) and graph theoretical approach (GTA) applied on the 54 and 100-bus primary power distribution systems. The simulation results show that the proposed approach performed better than the other listed algorithms and can be efficiently used for the optimal design of an advanced power distribution system.

Effects of long-term straw incorporation on the net global warming potential and the net economic benefit in a ricewheat cropping system in China  

Science Journals Connector (OSTI)

Abstract Straw incorporation has multiple effects on greenhouse gas emissions and soil productivity. However, few studies have comprehensively evaluated the effects of long-term straw incorporation. An ongoing long-term straw incorporation experiment in a ricewheat cropping system in China was established in 1990 and was used in the present study to evaluate the net global warming potential (NGWP) and the net economic benefit (NEB) of the straw return. The following four field treatments were included: a control (CK); N, P and K fertilization (NPK); fertilization plus a moderate rate of straw application (NPKS1); and fertilization plus a high rate of straw application (NPKS2). We calculated the increase in the soil organic carbon (SOC) and the straw-induced emissions of CH4 and N2O, which were expressed as the global warming potential (GWP) in units of CO2-equivalent (CO2-eq) at the 100-year scale. The straw-induced NEB was defined as the difference between the economic income, which was calculated by multiplying the increase in straw-induced crop grain yield by the grain price, and the economic loss was computed by multiplying the increase in straw-induced CO2-eq emissions by the carbon price. The results showed that long-term straw incorporation significantly increased the CH4 emissions and the topsoil SOC density. The GWP of the straw-induced CH4 emissions was 3.213.92 times that of the straw-induced SOC sequestration rate, suggesting that long-term direct straw incorporation in the ricewheat systems worsens rather than mitigates the climate change. Additionally, continuous straw incorporation slightly enhanced the rice and wheat grain yields, contributing to the production of the NEB. We determined that under the current carbon price, ranging from 2.55 to 31.71 EUR per ton CO2-eq, the direct straw incorporation will produce a positive NEB, ranging from 156 to 658 RMBha?1year?1, if the grain yield prices do not fluctuate, which does not provide a significant incentive for farmers to change from their traditional direct straw incorporation pattern. Considering the other benefits that the straw application produced, such as improving soil fertility and the water retention capacity, we recommend that the government should establish an incentive for ecological compensation to encourage farmers to implement proper straw incorporation, such as composting straw under aerobic conditions before application.

This paper presents a novel approach for optimal electric distribution system expansion planning (OEDSEP) using a hybrid energy hub concept. The proposed method uses an energy hub model to explore the impacts of energy carrier systems on OEDSEP procedure. This algorithm decomposes the OEDSEP problem into three subproblems to achieve an optimal expansion planning of a system in which the investment and operational costs are minimized, while the reliability of the system is maximized. The algorithm was successfully tested in the present research for an urban distribution system.

Evaluating Domestic Hot Water Distribution System Options With Validated Analysis Models  

SciTech Connect

A developing body of work is forming that collects data on domestic hot water consumption, water use behaviors, and energy efficiency of various distribution systems. A full distribution system developed in TRNSYS has been validated using field monitoring data and then exercised in a number of climates to understand climate impact on performance. This study builds upon previous analysis modelling work to evaluate differing distribution systems and the sensitivities of water heating energy and water use efficiency to variations of climate, load, distribution type, insulation and compact plumbing practices. Overall 124 different TRNSYS models were simulated. Of the configurations evaluated, distribution losses account for 13-29% of the total water heating energy use and water use efficiency ranges from 11-22%. The base case, an uninsulated trunk and branch system sees the most improvement in energy consumption by insulating and locating the water heater central to all fixtures. Demand recirculation systems are not projected to provide significant energy savings and in some cases increase energy consumption. Water use is most efficient with demand recirculation systems, followed by the insulated trunk and branch system with a central water heater. Compact plumbing practices and insulation have the most impact on energy consumption (2-6% for insulation and 3-4% per 10 gallons of enclosed volume reduced). The results of this work are useful in informing future development of water heating best practices guides as well as more accurate (and simulation time efficient) distribution models for annual whole house simulation programs.

Locoregional Failure in Early-Stage Breast Cancer Patients Treated With Radical Mastectomy and Adjuvant Systemic Therapy: Which Patients Benefit From Postmastectomy Irradiation?  

SciTech Connect

Purpose: To assess the locoregional failure in patients with Stage I-II breast cancer treated with radical mastectomy and to evaluate whether a subset of these patients might be at sufficiently high risk of locoregional recurrence (LRR) to benefit from postmastectomy irradiation (PMRT). Methods and Materials: Stage I-II breast cancer patients (n = 150) treated with radical mastectomy without adjuvant irradiation between 1999 and 2005 were analyzed. The pattern of LRR was reported. Kaplan-Meier analysis was used to calculate rates of LRR, and Cox proportional hazards methods were used to evaluate potential risk factors. Results: Median follow-up was 75 months. Mean patient age was 56 years. One-hundred forty-three (95%) patients received adjuvant systemic therapy: 85 (57%) hormonal therapy alone, 14 (9%) chemotherapy alone, and 44 (29%) both chemotherapy and hormonal therapy. Statistically significant factors associated with increased risk of LRR were premenopausal status (p = 0.004), estrogen receptor negative cancer (p = 0.02), pathologic grade 3 (p = 0.02), and lymphovascular invasion (p = 0.001). T and N stage were not associated with increased risk of regional recurrence. The 5-year LRR rate for patients with zero or one, two, three, and four risk factors was 1%, 10.3%, 24.2%, and 75%, respectively. Conclusions: A subset of patients with early-stage breast cancer is at high risk of LRR, and therefore PMRT might be beneficial.

Scalable Distributed Automation System: Scalable Real-time Decentralized Volt/VAR Control  

SciTech Connect

GENI Project: Caltech is developing a distributed automation system that allows distributed generatorssolar panels, wind farms, thermal co-generation systemsto effectively manage their own power. To date, the main stumbling block for distributed automation systems has been the inability to develop software that can handle more than 100,000 distributed generators and be implemented in real time. Caltechs software could allow millions of generators to self-manage through local sensing, computation, and communication. Taken together, localized algorithms can support certain global objectives, such as maintaining the balance of energy supply and demand, regulating voltage and frequency, and minimizing cost. An automated, grid-wide power control system would ease the integration of renewable energy sources like solar power into the grid by quickly transmitting power when it is created, eliminating the energy loss associated with the lack of renewable energy storage capacity of the grid.

Distributed monitoring system for electric-motor-driven compressors  

SciTech Connect

Personnel in the Instrumentation and Controls Division at the Oak Ridge National Laboratory, in association with the United States Enrichment corporation (USEC), the Navy, and various Department of Energy sponsors, have been involved in the development and application of motor-current signature analysis (CSA) for several years. In that time CSA has proven to not only be useful for manually applied periodic monitoring of electrically driven equipment but it has also been demonstrated to be well suited for dedicated monitoring systems in industrial settings. Recent work has resulted in the development and installation of a system that can monitor up to 640 motor and compressor stages for various aerodynamic conditions in the gas compressors and electrical problems in the drive motors. This report describes a demonstration of that technology installed on 80 stages at each of the two USEC uranium enrichment plants.

Distributed generation with photovoltaic systems: A utility perspective  

SciTech Connect

Today PV power systems are already cost-effective and commonly employed in a wide range of remote applications such as electricity supply to isolated users and small communities; water pumping and desalination; powering of service equipment such as radio repeaters; pipelines and well-heads cathodic protection. PV systems can easily cover a broad range of power requirements, allowing them to take advantage of new niche markets as they develop. Besides such applications a ``non-power'', low performance, consumer market also exists (watches, calculators, gadgets) that has already reached a stable growth condition. In the last decade, an increase has been experienced of about three times in the amount of module shipments (103 MW expected in 1997), a more balanced regional manufacturer share has developed, crystalline technology has maintained its lead, and a more market-oriented application share has appeared (at present most applications are for stand-alone).

Siddiqui Conference Name 7th IEEE Vehicle Power and Propulsion Conference Date Published 09/2011 Publisher LBNL Conference Location Chicago, IL Keywords electricity markets and policy group, energy analysis and environmental impacts department Abstract Connecting electric storage technologies to smartgrids will have substantial implications in building energy systems. Local storage will enable demand response. Mobile storage devices in electric vehicles (EVs) are in direct competition with conventional stationary sources at the building. EVs will change the financial as well as environmental attractiveness of on-site generation (e.g. PV, or fuel cells). In order to examine the impact of EVs on building energy costs and CO2 emissions in 2020, a distributed-energy-resources adoption problem is formulated as a mixed-integer linear program with minimization of annual building energy costs or CO2 emissions. The mixed-integer linear program is applied to a set of 139 different commercial buildings in California and example results as well as the aggregated economic and environmental benefits are reported. The research shows that considering second life of EV batteries might be very beneficial for commercial buildings.

Biofouling of groundwater distribution systems by Thiothrix spp.  

SciTech Connect

Thiothrix spp., sulfide oxidizing filamentous bacteria, were found to be the main bacterial component of aquatic biofilms causing biofouling in selected municipal water storage tanks, private wells, and drip irrigation systems in Florida. The water originated from the upper Floridan aquifer and associated aquifers in Central and North Florida. Samples were examined where visible biofilms had a white, slimy, filamentous appearance indicative of Thiothrix spp. The detection of Thiothrix spp. was confirmed by enzyme-liked immunosorbent assay (ELISA). These observations confirm that these bacteria and associated extracellular material play an important role in formation of biofilms, which in turn may induce physical changes leading to significant biofouling. These studies suggest that Thiothrix spp.-associated biofouling occurs at an interface where reduced sulfide-containing water contacts aerated water and a surface or substrate is available for attachment.

Practical stability assessment of distributed synchronous generators under variations in the system equilibrium conditions  

Science Journals Connector (OSTI)

Abstract This paper proposes a method to assess the practical stability of power distribution systems with synchronous generators subject to changes in the system equilibrium conditions due to fast varying loads. The concept of practical stability deals with two known state-space regions ?1 (which contains all the initial conditions reflecting the perturbations at which the system is subject during its operation) and ?2 (which represents the operating security region of the power distribution system) satisfying ?1??2. The practical stability problem and the focus of this paper is to determine under which conditions the system trajectories will be confined into a security region of operation for a certain time interval of interest, as the equilibrium point of the model changes. This study was carried out using a mathematical model of the distribution system with synchronous generators in the form of a switched affine system. This proposed model is capable of describing the system behavior over a certain period within which changes on the equilibrium conditions of the system can occur. Sufficient conditions for the power distribution system with synchronous generators described as a switched affine system to be practically stable with respect to its operating security region ?2 are given in the form of matrix inequalities constraints. The results, obtained for the model of a cogeneration plant of 10MW added to a distribution network constituted by a feeder and six buses, show that the less stringent properties of the concept of practical stability can be very well-suited to the security analysis of power systems subjected to frequent variations in the load level.

Feasibility study and roadmap to improve residential hot water distribution systems  

SciTech Connect

Residential building practice currently ignores the losses of energy and water caused by the poor design of hot water systems. These losses include: the waste of water while waiting for hot water to get to the point of use; the wasted heat as water cools down in the distribution system after a draw; and the energy to reheat water that was already heated once before. A feasibility study and an action plan for a proposed research project involving residential hot water distribution systems is being developed. The feasibility study will use past work to estimate of hot water and energy loses caused by current hot water distribution systems in residences. Proposed research project, or roadmap, will develop recommendations for improvements to residential hot water distribution systems. The roadmap addresses the technical obstacles and gaps in our knowledge that prevent water and energy reductions and market adoption of water- and energy-efficient technologies. The initial results of the feasibility study are presented here along with a discussion of a roadmap to improve the efficiency of residential hot water distribution systems.

A study of pressure losses in residential air distribution systems  

SciTech Connect

An experimental study was conducted to evaluate the pressure drop characteristics of residential duct system components that are either not available or not thoroughly (sometimes incorrectly) described in existing duct design literature. The tests were designed to imitate cases normally found in typical residential and light commercial installations. The study included three different sizes of flexible ducts, under different compression configurations, splitter boxes, supply boots, and a fresh air intake hood. The experimental tests conformed to ASHRAE Standard 120P--''Methods of Testing to Determine Flow Resistance of HVAC Air Ducts and Fittings''. The flexible duct study covered compressibility and bending effects on the total pressure drop, and the results showed that the available published references tend to underestimate the effects of compression in flexible ducts that can increase pressure drops by up to a factor of nine. The supply boots were tested under different configurations including a setup where a flexible duct elbow connection was considered as an integral part of the supply boot. The supply boots results showed that diffusers can increase the pressure drop by up to a factor of two in exit fittings, and the installation configuration can increase the pressure drop by up to a factor of five. The results showed that it is crucial for designers and contractors to be aware of the compressibility effects of the flexible duct, and the installation of supply boots and diffusers.

Towards a Centralized Scheduling Framework for Communication Flows in Distributed Systems  

E-Print Network (OSTI)

The overall performance of a distributed system is highly dependent on the communication efficiency of the system. Although network resources (links, bandwidth) are becoming increasingly more available, the communication performance of data transfers involving large volumes of data does not necessarily improve at the same rate. This is due to the inefficient usage of the available network resources. A solution to this problem consists of data transfer scheduling techniques, which manage and allocate the network resources in an efficient manner. In this paper we present several online and offline data transfer optimization techniques, in the context of a centrally controlled distributed system.

Investigation of assimilable organic carbon (AOC) and bacterial regrowth in drinking water distribution system  

Science Journals Connector (OSTI)

This paper investigated the variation of assimilable organic carbon (AOC) concentrations in water from several typical water treatment plants and distribution systems in a northern city of China. It is concluded from this study that: (1) The AOC in most of the product water of the studied water treatment plants and the water from the associated distribution systems could not meet the biostability criteria of 50100?g/L. (2) Only 4% of the measured AOC concentrations were less than 100?g/L. However, about half of the measured AOC values were less than 200?g/L. (3) Better source water quality resulted in lower AOC concentrations. (4) The variation of AOC concentrations in distribution systems was affected by chlorine oxidation and bacterial activity: the former resulted in an increase of AOC value while the latter led to a reduction in AOC. (5) The variation of AOC concentration followed different patterns in different distribution systems or different seasons due to their respective operational characteristics.

Harmonic effects of solar geomagnetically induced currents on the electrical distribution system in nuclear power plants  

SciTech Connect

Most previous analysis on the effects of geomagnetically induced currents (GIC) on electric utility systems has steady-state phenomena, with the main interest in the generator step-up transformer and the off-site power system. This paper begins to investigate the possible effects that a GIC event might have on the power plant itself, by examining the harmonic distortion that could exist at various voltage levels in the on-site distribution system.

Research on Optimal Operation Method of Large Scale Urban Water Distribution System  

Science Journals Connector (OSTI)

Abstract In consideration of using fewer decision variables in building least cost pumping operation optimal, the two-phase optimal method is used as the frame. By abstracting pump stations into high level reservoirs, the water distribution system hydraulic model can be modified into a modality, which can be used in first optimal phase of two-phase optimal method. And by building on feasible pump combination database, a new optimal method in the second optimal phase will be proposed. And the proposed new method in the second optimal phase will be embedded into the first optimal phase, so that the problem of results discordant in different phases of two-phase optimal method will be solved. By introducing new concept and improving present optimal method, a more practical optimal operation method of water distribution system (WDS) will be established. By applying to a large scale water distribution system, the practicability of proposed method has been evaluated.

Quasi-parallel network applications in real-time distribution management system  

Science Journals Connector (OSTI)

In modern distribution management systems (DMSs), the real-time calculation of the network's state plays an important role for the operation of the network. High sophisticated algorithms for the estimation and calculation of the system's state like distribution system state estimation (DSSE), distribution system power and short circuit calculations (DSPF and SCC), voltage var control (VVC) and others must operate in a real-time environment, supplying subsequently running functions with reliable input data. Closed-loop requirements also increase the requirements concerning performance, availability and robustness. In this paper, an implementation of the sequence control of different DMS-network applications is presented. This proposed real-time scheduler takes advantage of CPU-cores inside of a modern computer system: by passing subtasks to different CPU-cores, the overall performance is significantly increased. The scheduling process is analysed in detail taking the nature of a distribution system into consideration. The presentation is finalised with a report about the gain of performance for the state estimation process.

On September 26--29, 1988, Hughes Associates, Inc., Fire Protection Engineers, accompanied by Rocky Flats Fire Department engineers and suppression personnel, conducted water flow tests at the Rocky Flats plant site. Thirty-seven flows from various points throughout the plant site were taken on the existing domestic supply/fire main installation to assure comprehensive and thorough representation of the Rocky Flats water distribution system capability. The analysis was completed in four phases which are described, together with a summary of general conclusions and recommendations.

Impact of Distributed Wind on Bulk Power System Operations in ISO-NE: Preprint  

SciTech Connect

The work presented in this paper aims to study the impact of a range of penetration levels of distributed wind on the operation of the electric power system at the transmission level. This paper presents a case study on the power system in Independent System Operator New England. It is analyzed using PLEXOS, a commercial power system simulation tool. The results show that increasing the integration of distributed wind reduces total variable electricity generation costs, coal- and gas-fired electricity generation, electricity imports, and CO2 emissions, and increases wind curtailment. The variability and uncertainty of wind power also increases the start-up and shutdown costs and ramping of most conventional power plants.

Anode-cathode power distribution systems and methods of using the same for electrochemical reduction  

DOE Patents (OSTI)

Power distribution systems are useable in electrolytic reduction systems and include several cathode and anode assembly electrical contacts that permit flexible modular assembly numbers and placement in standardized connection configurations. Electrical contacts may be arranged at any position where assembly contact is desired. Electrical power may be provided via power cables attached to seating assemblies of the electrical contacts. Cathode and anode assembly electrical contacts may provide electrical power at any desired levels. Pairs of anode and cathode assembly electrical contacts may provide equal and opposite electrical power; different cathode assembly electrical contacts may provide different levels of electrical power to a same or different modular cathode assembly. Electrical systems may be used with an electrolyte container into which the modular cathode and anode assemblies extend and are supported above, with the modular cathode and anode assemblies mechanically and electrically connecting to the respective contacts in power distribution systems.

An integrated technique for fault location and section identification in distribution systems  

Science Journals Connector (OSTI)

Abstract This paper proposes an integrated impedance and transient-based formulation for fault location in distribution systems. The technique uses an extended apparent impedance analysis in order to estimate the fault distance, taking into account the unbalanced operation, intermediate loads, laterals, and time-varying load profile of distribution systems. The fault distance information is used in calculating characteristic frequencies associated to each possible fault location. A transient analysis is proposed to evaluate the spectral content of the fault-generated traveling wave, thus identifying its most significant frequency components. Based on the timefrequency correlation it is possible to eliminate the multiple estimates obtained from the impedance-based method, thus resulting in a single fault location. Aiming to verify the application of the proposed methodology, simulations were carried out in the ATP/EMTP Software considering a real distribution feeder with 3472 buses.

Integrated Computing, Communication, and Distributed Control of Deregulated Electric Power Systems  

SciTech Connect

Restructuring of the electricity market has affected all aspects of the power industry from generation to transmission, distribution, and consumption. Transmission circuits, in particular, are stressed often exceeding their stability limits because of the difficulty in building new transmission lines due to environmental concerns and financial risk. Deregulation has resulted in the need for tighter control strategies to maintain reliability even in the event of considerable structural changes, such as loss of a large generating unit or a transmission line, and changes in loading conditions due to the continuously varying power consumption. Our research efforts under the DOE EPSCoR Grant focused on Integrated Computing, Communication and Distributed Control of Deregulated Electric Power Systems. This research is applicable to operating and controlling modern electric energy systems. The controls developed by APERC provide for a more efficient, economical, reliable, and secure operation of these systems. Under this program, we developed distributed control algorithms suitable for large-scale geographically dispersed power systems and also economic tools to evaluate their effectiveness and impact on power markets. Progress was made in the development of distributed intelligent control agents for reliable and automated operation of integrated electric power systems. The methodologies employed combine information technology, control and communication, agent technology, and power systems engineering in the development of intelligent control agents for reliable and automated operation of integrated electric power systems. In the event of scheduled load changes or unforeseen disturbances, the power system is expected to minimize the effects and costs of disturbances and to maintain critical infrastructure operational.

This project is focused on modeling, quantifying, and mitigating the impacts of large utility-scale PV systems (generally 1-5 MW in size) that are interconnected to the distribution system. This report discusses the concerns utilities have when interconnecting large PV systems that interconnect using PV inverters (a specific application of frequency converters). Additionally, a number of capabilities of PV inverters are described that could be implemented to mitigate the distribution system-level impacts of high-penetration PV integration. Finally, the main issues that need to be addressed to ease the interconnection of large PV systems to the distribution system are presented.

INTELLIGENT MONITORING SYSTEM WITH HIGH TEMPERATURE DISTRIBUTED FIBEROPTIC SENSOR FOR POWER PLANT COMBUSTION PROCESSES  

SciTech Connect

The objective of the proposed work is to develop an intelligent distributed fiber optical sensor system for real-time monitoring of high temperature in a boiler furnace in power plants. Of particular interest is the estimation of spatial and temporal distributions of high temperatures within a boiler furnace, which will be essential in assessing and controlling the mechanisms that form and remove pollutants at the source, such as NOx. The basic approach in developing the proposed sensor system is three fold: (1) development of high temperature distributed fiber optical sensor capable of measuring temperatures greater than 2000 C degree with spatial resolution of less than 1 cm; (2) development of distributed parameter system (DPS) models to map the three-dimensional (3D) temperature distribution for the furnace; and (3) development of an intelligent monitoring system for real-time monitoring of the 3D boiler temperature distribution. Under Task 1, the efforts focused on developing an innovative high temperature distributed fiber optic sensor by fabricating in-fiber gratings in single crystal sapphire fibers. So far, our major accomplishments include: Successfully grown alumina cladding layers on single crystal sapphire fibers, successfully fabricated in-fiber gratings in single crystal sapphire fibers, and successfully developed a high temperature distributed fiber optic sensor. Under Task 2, the emphasis has been on putting into place a computational capability for simulation of combustors. A PC workstation was acquired with dual Xeon processors and sufficient memory to support 3-D calculations. An existing license for Fluent software was expanded to include two PC processes, where the existing license was for a Unix workstation. Under Task 3, intelligent state estimation theory is being developed which will map the set of 1D (located judiciously within a 3D environment) measurement data into a 3D temperature profile. This theory presents a semigroup-based approach to the design and training of a system type neural network which performs function extrapolation. The assumption of the semigroup property suffices to guarantee the existence of a generic mathematical architecture and operation which is explicit enough to support the direct design and training of a neural network.
