Facility Microgrids  

Science Conference Proceedings (OSTI)

Microgrids are receiving a considerable interest from the power industry, partly because their business and technical structure shows promise as a means of taking full advantage of distributed generation. This report investigates three issues associated with facility microgrids: (1) Multiple-distributed generation facility microgrids' unintentional islanding protection, (2) Facility microgrids' response to bulk grid disturbances, and (3) Facility microgrids' intentional islanding.

Assessment of the Economic Potential of Microgrids for Reactive Power Supply  

DOE Green Energy (OSTI)

As power generation from variable distributed energy resources (DER) grows, energy flows in the network are changing, increasing the requirements for ancillary services, including voltage support. With the appropriate power converter, DER can provide ancillary services such as frequency control and voltage support. This paper outlines the economic potential of DERs coordinated in a microgrid to provide reactive power and voltage support at its point of common coupling. The DER Customer Adoption Model assesses the costs of providing reactive power, given local utility rules. Depending on the installed DER, the cost minimizing solution for supplying reactive power locally is chosen. Costs include the variable cost of the additional losses and the investment cost of appropriately over-sizing converters or purchasing capacitors. A case study of a large health care building in San Francisco is used to evaluate different revenue possibilities of creating an incentive for microgrids to provide reactive power.

Value and Technology Assessment to Enhance the Business Case for the CERTS Microgrid  

SciTech Connect

The CERTS Microgrid concept is an advanced approach for enabling integration of, in principle, an unlimited quantity of distributed energy resources into the electricity grid. A key feature of a microgrid, is its ability, during a utility grid disturbance, to separate and isolate itself from the utility seamlessly with no disruption to the loads within the microgrid (including no reduction in power quality). Then, when the utility grid returns to normal, the microgrid automatically resynchronizes and reconnects itself to the grid, in an equally seamless fashion. What is unique about the CERTS Microgrid is that it can provide this technically challenging functionality without extensive (i.e., expensive) custom engineering. In addition, the design of the CERTS Microgrid also provides high system reliability and great flexibility in the placement of distributed generation within the microgrid. The CERTS Microgrid offers these functionalities at much lower costs than traditional approaches by incorporating peer-to-peer and plug-and-play concepts for each component within the Microgrid. The predecessor to the current project involved the construction of and completion of initial testing using the world's first, full-scale, inverter-based, distributed generation test bed. The project demonstrated three advanced techniques, collectively referred to as the CERTS Microgrid concept, which collectively significantly reduce the level of custom field engineering needed to operate microgrids consisting of small generating sources. The techniques are: (1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation; (2) an approach to electrical protection within the microgrid that does not depend on high fault currents; and (3) a method for microgrid control that achieves voltage and frequency stability under both grid and islanded conditions without requiring high-speed communications. The work conducted in this phase of RD&D on the CERTS Microgrid Concept builds upon this base of technical accomplishments to prioritize, develop, and then demonstrate technology enhancements to further enhance the business case for microgrids. That is, having demonstrated the technical feasibility of microgrid functions, RD&D optimization efforts are now needed to accelerate commercial deployment. The current phase is a contribution to these efforts. This project involved seven distinct analysis, bench-, and full-scale testing tasks. The first five tasks were described in the original proposal submitted and awarded through DOE's solicitation. Two additional tasks were added to address issues that had been identified in the earlier, first phase of testing.

Shape of the microgrid  

Science Conference Proceedings (OSTI)

Restrictions on expansion of traditional centralized generating and delivery systems may be becoming so tight in the industrialized countries that they cannot reasonably be expected meet future electricity demand growth at acceptable cost. Meanwhile, technological advances, notably improved power electronics that permit grid interconnection of asynchronous generation sources, is tilting the economics of power generation back towards smaller scales, thereby reversing a century long trend towards the central control paradigm. Special power quality requirements or opportunities for combined heat and power applications make on-site generation an even more attractive option for customers. The existence of a significant amount of electricity sources dispersed throughout the low voltage distribution system could create a power system quite different to the one we are familiar with and creating it offers significant research and engineering challenges. Moreover, the electrical and economic relationships between customers and the distribution utility and among customers may take forms quite distinct from those we know today. For example, rather than devices being individually interconnected in parallel with the grid, they may be grouped with loads in a semi-autonomous neighborhood that could be termed a microgrid. A microgrid is a cluster of small (by the standards of current power systems, e.g. microgrid concept is the notion of a flexible, yet controllable electronic interface between the microgrid and the familiar wider power system, or macrogrid. This interface essentially isolates the two sides electrically; and yet connects them economically by allowing delivery and receipt of electrical energy and ancillary services (EE&AS) at the interface. From the customer side of the interface, the microgrid should appear as an autonomous power system meeting the power quality and reliability requirements of the customer. Such issues as local voltage, reliability, losses and quality of power should be those that support the customers' objectives. From the macrogrid side, however, the microgrid should appear as a legitimate entity akin to current interconnected generators or loads. A key distinction between microgrids and our familiar arrangements is the expanded role of electricity endusers in determining the pattern of development of the overall power system, which must not only accommodate purchases and sales of EE&AS to and from established markets but also contractual agreements between microgrids. Fundamentally, the characteristics and capabilities of the microgrid will be determined by its internal requirements together with the technical, economic, and regulatory opportunities and constraints it faces, and not by established objectives for capacity expansion and reliability of the macrogrid. The goal of Consortium for Electric Reliability Technology Solutions (CERTS) work underway at the Berkeley Lab is to anticipate possible patterns of microgrid development that can help focus research efforts on the key technical problems that must be solved to enable microgrid deployment.

Microgrid Testing  

Science Conference Proceedings (OSTI)

With the publication of IEEE 1574.4 Guide for Design, Operation, and Integration of Distributed Resource Island Systems with Electric Power Systems, there is an increasing amount of attention on not only the design and operations of microgrids, but also on the proper operation and testing of these systems. This standard provides alternative approaches and good practices for the design, operation, and integration of microgrids. This includes the ability to separate from and reconnect to part of the utility grid while providing power to the islanded power system. This presentation addresses the industry need to develop standardized testing and evaluation procedures for microgrids in order to assure quality operation in the grid connected and islanded modes of operation.

Distributed energy resources including distributed generation and distributed storage are sources of energy located near local loads and can provide a variety of benefits including improved reliability if they are properly operated in the electrical distribution system. Microgrids are systems that have at least one distributed energy resource and associated loads and can form intentional islands in the electrical distribution systems. This paper gives an overview of the microgrid operation. Microgrid testing experiences from different counties was also provided.

Microgrid: A Conceptual Solution  

E-Print Network (OSTI)

Abstract — Application of individual distributed generators can cause as many problems as it may solve. A better way to realize the emerging potential of distributed generation is to take a system approach which views generation and associated loads as a subsystem or a “microgrid”. During disturbances, the generation and corresponding loads can separate from the distribution system to isolate the microgrid’s load from the disturbance (providing UPS services) without harming the transmission grid’s integrity. This ability to island generation and loads together has a potential to provide a higher local reliability than that provided by the power system as a whole. In this model it is also critical to be able to use the waste heat by placing the sources near the heat load. This implies that a unit can be placed at any point on the electrical system as required by the location of the heat load.

Status of Overseas Microgrid Programs:Microgrid Research Activities in the U.S.  

Science Conference Proceedings (OSTI)

Research on microgrids in the U.S. has taken a somewhat different path than parallel efforts in Japan and Europe, and this distinction is often noted in international research forums. In general, reliability and power quality in North America is poor compared to other developed countries. For example, in the U.S., the average annual expected outage duration is a few hours, whereas in Japan, it is only a few minutes. Power quality problems in the U.S. are both large scale, such as the August 2003 blackout, and local, such as damaging voltage sags. Meeting the increasingly demanding requirements of a modern digital economy would then seem to offer a more daunting challenge for the U.S. than elsewhere, and certainly, concern that the existing power delivery system will prove inadequate for future gourmet requirements has been a motivating driver of U.S. research. This objective tends to translate into a desire for microgrids to seamlessly island when grid power is interrupted or its quality is inadequate, and to (also seamlessly) reconnect when normal service has been restored. In a sense, the microgrid is perceived as acting as an uninterruptible power supply (UPS), and sometimes even as a competitor to existing UPS options. Nonetheless, this difference is often over-stated, and the other threads that motivate microgrid research also exist in the U.S., e.g. the desire to expand renewable generation and the need to increase the efficiency of fossil-fired generation by the useful local application of waste heat in combined heat and power (CHP) systems, Further, over time, the differences are blurring as concerns about climate change increasingly dominate objectives worldwide. This article describes the CERTS Microgrid, which is almost certainly the best known U.S. example, and also briefly mentions some other U.S. microgrid research.

CERTS Microgrid Laboratory Test Bed  

Science Conference Proceedings (OSTI)

The objective of the CERTS Microgrid Test Bed project was to enhance the ease of integrating energy sources into a microgrid. The project accomplished this objective by developing and demonstrating three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of generating sources less than 100kW. The techniques comprising the CERTS Microgrid concept are: 1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation, islanding the microgrid's load from a disturbance, thereby maintaining a higher level of service, without impacting the integrity of the utility's electrical power grid; 2) an approach to electrical protection within a limited source microgrid that does not depend on high fault currents; and 3) a method for microgrid control that achieves voltage and frequency stability under islanded conditions without requiring high-speed communications between sources. These techniques were demonstrated at a full-scale test bed built near Columbus, Ohio and operated by American Electric Power. The testing fully confirmed earlier research that had been conducted initially through analytical simulations, then through laboratory emulations,and finally through factory acceptance testing of individual microgrid components. The islanding and resychronization method met all Institute of Electrical and Electronics Engineers Standard 1547 and power quality requirements. The electrical protection system was able to distinguish between normal and faulted operation. The controls were found to be robust under all conditions, including difficult motor starts and high impedance faults. The results from these tests are expected to lead to additional testing of enhancements to the basic techniques at the test bed to improve the business case for microgrid technologies, as well to field demonstrations involving microgrids that involve one or more of the CERTS Microgrid concepts. Future planned microgrid work involves unattended continuous operation of the microgrid for 30 to 60 days to determine how utility faults impact the operation of the microgrid and to gage the power quality and reliability improvements offered by microgrids.

A system for controlling a microgrid includes microgrid assets and a tieline for coupling the microgrid to a bulk grid; and a tieline controller coupled to the tieline. At least one of the microgrid assets comprises a different type of asset than another one of the microgrid assets. The tieline controller is configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, bulk grid conditions, or combinations thereof.

Microgrid cyber security reference architecture.  

SciTech Connect

This document describes a microgrid cyber security reference architecture. First, we present a high-level concept of operations for a microgrid, including operational modes, necessary power actors, and the communication protocols typically employed. We then describe our motivation for designing a secure microgrid; in particular, we provide general network and industrial control system (ICS)-speci c vulnerabilities, a threat model, information assurance compliance concerns, and design criteria for a microgrid control system network. Our design approach addresses these concerns by segmenting the microgrid control system network into enclaves, grouping enclaves into functional domains, and describing actor communication using data exchange attributes. We describe cyber actors that can help mitigate potential vulnerabilities, in addition to performance bene ts and vulnerability mitigation that may be realized using this reference architecture. To illustrate our design approach, we present a notional a microgrid control system network implementation, including types of communica- tion occurring on that network, example data exchange attributes for actors in the network, an example of how the network can be segmented to create enclaves and functional domains, and how cyber actors can be used to enforce network segmentation and provide the neces- sary level of security. Finally, we describe areas of focus for the further development of the reference architecture.

Energy manager design for microgrids  

Science Conference Proceedings (OSTI)

On-site energy production, known as distributed energy resources (DER), offers consumers many benefits, such as bill savings and predictability, improved system efficiency, improved reliability, control over power quality, and in many cases, greener electricity. Additionally, DER systems can benefit electric utilities by reducing congestion on the grid, reducing the need for new generation and transmission capacity, and offering ancillary services such as voltage support and emergency demand response. Local aggregations of distributed energy resources (DER) that may include active control of on-site end-use energy devices can be called microgrids. Microgrids require control to ensure safe operation and to make dispatch decisions that achieve system objectives such as cost minimization, reliability, efficiency and emissions requirements, while abiding by system constraints and regulatory rules. This control is performed by an energy manager (EM). Preferably, an EM will achieve operation reasonably close to the attainable optimum, it will do this by means robust to deviations from expected conditions, and it will not itself incur insupportable capital or operation and maintenance costs. Also, microgrids can include supervision over end-uses, such as curtailing or rescheduling certain loads. By viewing a unified microgrid as a system of supply and demand, rather than simply a system of on-site generation devices, the benefits of integrated supply and demand control can be exploited, such as economic savings and improved system energy efficiency.

Advanced concepts for controlling energy surety microgrids.  

Science Conference Proceedings (OSTI)

Today, researchers, engineers, and policy makers are seeking ways to meet the world's growing demand for energy while addressing critical issues such as energy security, reliability, and sustainability. Many believe that distributed generators operating within a microgrid have the potential to address most of these issues. Sandia National Laboratories has developed a concept called energy surety in which five of these 'surety elements' are simultaneously considered: energy security, reliability, sustainability, safety, and cost-effectiveness. The surety methodology leads to a new microgrid design that we call an energy surety microgrid (ESM). This paper discusses the unique control requirement needed to produce a microgrid system that has high levels of surety, describes the control system from the most fundamental level through a real-world example, and discusses our ideas and concepts for a complete system.

CERTS Microgrid Laboratory Test Bed - PIER Final Project Report  

Science Conference Proceedings (OSTI)

The objective of the CERTS Microgrid Laboratory Test Bed project was to enhance the ease of integrating small energy sources into a microgrid. The project accomplished this objective by developing and demonstrating three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of small generating sources. The techniques comprising the CERTS Microgrid concept are: 1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation; 2) an approach to electrical protection within the microgrid that does not depend on high fault currents; and 3) a method for microgrid control that achieves voltage and frequency stability under islanded conditions without requiring high-speed communications. The techniques were demonstrated at a full-scale test bed built near Columbus, Ohio and operated by American Electric Power. The testing fully confirmed earlier research that had been conducted initially through analytical simulations, then through laboratory emulations, and finally through factory acceptance testing of individual microgrid components. The islanding and resychronization method met all Institute of Electrical and Electronics Engineers 1547 and power quality requirements. The electrical protections system was able to distinguish between normal and faulted operation. The controls were found to be robust and under all conditions, including difficult motor starts. The results from these test are expected to lead to additional testing of enhancements to the basic techniques at the test bed to improve the business case for microgrid technologies, as well to field demonstrations involving microgrids that involve one or mroe of the CERTS Microgrid concepts.

Microgrids and Heterogeneous Power Quality and Reliability  

Science Conference Proceedings (OSTI)

This paper describes two stylized alternative visions of how the power system might evolve to meet future requirements for the high quality electricity service that modern digital economies demand, a supergrids paradigm and a dispersed paradigm. Some of the economics of the dispersed vision are explored, and perspectives are presented on both the choice of homogeneous universal power quality upstream in the electricity supply chain and on the extremely heterogeneous requirements of end-use loads. It is argued that meeting the demanding requirements of sensitive loads by local provision of high quality power may be more cost effective than increasing the quality of universal homogeneous supply upstream in the legacy grid. Finally, the potential role of microgrids in delivering heterogeneous power quality is demonstrated by reference to two ongoing microgrid tests in the U.S. and Japan.

While the long-term natural gas generation cost is stochastc, we initially assume that the microgrid may purchase electricity at a fixed retail rate from its utility. Using the real options approach, we find natural gas generation cost thresholds that trigger DG investment. Furthermore, the consideration of operational flexibility by the microgrid accelerates DG investment, while the option to disconnect entirely from the utility is not attractive. By allowing the electricity price to be stochastic, we next determine an

Distributed Generation Investment by a Microgrid under Uncertainty  

Science Conference Proceedings (OSTI)

This paper examines a California-based microgrid?s decision to invest in a distributed generation (DG) unit fuelled by natural gas. While the long-term natural gas generation cost is stochastic, we initially assume that the microgrid may purchase electricity at a fixed retail rate from its utility. Using the real options approach, we find a natural gas generation cost threshold that triggers DG investment. Furthermore, the consideration of operational flexibility by the microgrid increases DG investment, while the option to disconnect from the utility is not attractive. By allowing the electricity price to be stochastic, we next determine an investment threshold boundary and find that high electricity price volatility relative to that of natural gas generation cost delays investment while simultaneously increasing the value of the investment. We conclude by using this result to find the implicit option value of the DG unit when two sources of uncertainty exist.

Effect of Heat and Electricity Storage and Reliability on Microgrid Viability: A Study of Commercial Buildings in California and New York States  

Science Conference Proceedings (OSTI)

Berkeley Lab has for several years been developing methods for selection of optimal microgrid systems, especially for commercial building applications, and applying these methods in the Distributed Energy Resources Customer Adoption Model (DER-CAM). This project began with 3 major goals: (1) to conduct detailed analysis to find the optimal equipment combination for microgrids at a few promising commercial building hosts in the two favorable markets of California and New York, (2) to extend the analysis capability of DER-CAM to include both heat and electricity storage, and (3) to make an initial effort towards adding consideration of power quality and reliability (PQR) to the capabilities of DER-CAM. All of these objectives have been pursued via analysis of the attractiveness of a Consortium for Electric Reliability Technology Solutions (CERTS) Microgrid consisting of multiple nameplate 100 kW Tecogen Premium Power Modules (CM-100). This unit consists of an asynchronous inverter-based variable speed internal combustion engine genset with combined heat and power (CHP) and power surge capability. The essence of CERTS Microgrid technology is that smarts added to the on-board power electronics of any microgrid device enables stable and safe islanded operation without the need for complex fast supervisory controls. This approach allows plug and play development of a microgrid that can potentially provide high PQR with a minimum of specialized site-specific engineering. A notable feature of the CM-100 is its time-limited surge rating of 125 kW, and DER-CAM capability to model this feature was also a necessary model enhancement.

PSCAD/EMTDC-Based Modeling and Analysis of a Microgrid with Renewable Energy Sources  

E-Print Network (OSTI)

Microgrid is a relatively new concept which has gained significant attention recently due to the increasing penetration of distributed energy sources. It brings many benefits to the traditional distribution system. Couples of microgrid testbeds in the forms of either hardware facilities or software simulation systems have been developed to study microgrid issues in many institutes throughout the world. In the work presented in this thesis, a microgrid system model in PSCAD/EMTDC was developed. The proposed microgrid system includes fundamental power system component models, two renewable energy source models (wind and solar) and one energy storage source model. Different case studies were conducted. The results from the simulation case studies showed that the proposed microgrid system in PSCAD had satisfactory performance under different scenarios with renewable energy sources. The proposed microgrid system model can be used for further research on microgrid issues.

International physical protection self-assessment tool for chemical facilities.  

SciTech Connect

This report is the final report for Laboratory Directed Research and Development (LDRD) Project No.130746, International Physical Protection Self-Assessment Tool for Chemical Facilities. The goal of the project was to develop an exportable, low-cost, computer-based risk assessment tool for small to medium size chemical facilities. The tool would assist facilities in improving their physical protection posture, while protecting their proprietary information. In FY2009, the project team proposed a comprehensive evaluation of safety and security regulations in the target geographical area, Southeast Asia. This approach was later modified and the team worked instead on developing a methodology for identifying potential targets at chemical facilities. Milestones proposed for FY2010 included characterizing the international/regional regulatory framework, finalizing the target identification and consequence analysis methodology, and developing, reviewing, and piloting the software tool. The project team accomplished the initial goal of developing potential target categories for chemical facilities; however, the additional milestones proposed for FY2010 were not pursued and the LDRD funding therefore was redirected.

Distributed Generation Investment by a Microgrid UnderUncertainty  

Science Conference Proceedings (OSTI)

This paper examines a California-based microgrid s decision to invest in a distributed generation (DG) unit that operates on natural gas. While the long-term natural gas generation cost is stochastic, we initially assume that the microgrid may purchase electricity at a fixed retail rate from its utility. Using the real options approach, we find natural gas generating cost thresholds that trigger DG investment. Furthermore, the consideration of operational flexibility by the microgrid accelerates DG investment, while the option to disconnect entirely from the utility is not attractive. By allowing the electricity price to be stochastic, we next determine an investment threshold boundary and find that high electricity price volatility relative to that of natural gas generating cost delays investment while simultaneously increasing the value of the investment. We conclude by using this result to find the implicit option value of the DG unit.

This paper describes two stylized alternative visions inpopular currencyof how the power system might evolve to meet futurerequirements for the high quality electricity service that modern digitaleconomies demand, a supergrids paradigm and a dispersed paradigm. Some ofthe economics of the dispersed vision are explored. Economic perspectivesare presented on both the choice of homogeneous universal power qualityupstream in the electricity supply, and also on the extremelyheterogeneous require-ments of end-use loads. Finally, the potential roleof microgrids in delivering heterogeneous power quality is demonstratedby reference to two ongoing microgrid tests in the U.S. andJapan.

International DSM and DSM program evaluation: An INDEEP assessment  

Science Conference Proceedings (OSTI)

This paper discusses the current level of demand-side management (DSM) occurring in selected European countries and reviews the availability of information on DSM programs and program evaluation. Next, thirteen European DSM programs are compared by examining such factors as: motivations for program implementation, marketing methods, participation rates, total energy savings, and program costs. The transfer of DSM program results and experiences found in these case studies is also discussed, as well as the lessons learned during the design, implementation, and evaluation of these programs. This paper represents a preliminary assessment of the state of DSM and DSM program evaluation in Europe. The findings from this work also represent the first steps in a joint international effort to compile and analyze the measured results of energy efficiency programs in a consistent and comprehensive fashion. The authors find that these programs represent cost-effective resources: the cost of energy saved by the programs ranged from a low of 0.0005 ECUs/kWh (0.01 {cents}/kWh) to a high of 0.077 ECUs/kWh (9.7 {cents}/kWh), with an average cost of 0.027 ECUs/kWh (3.3 {cents}/kWh). Weighted by energy savings, the average cost of energy saved by the programs was 0.014 ECUs/kWh (1.8 {cents}/kWh).

A microgrid with wireless communication links for microgrid control has been designed and developed. The complete simulation model has been developed in MatLab SimuLink with seamless integration of the power subsystem and the communication subsystem. Unlike the conventional co-simulators that usually glue two existing simulators together by creating an interface, which has a steep learning curve, the proposed simulator is a compact single-unit model. Detailed modeling of the power subsystem and communication system is presented as well as the microgrid control architecture and strategies. The impact of different communication system performances on microgrid control has been studied and evaluated in the proposed simulator.

Micro-Grids for Colonias (TX)  

Science Conference Proceedings (OSTI)

This report describes the results of the final implementation and testing of a hybrid micro-grid system designed for off-grid applications in underserved Colonias along the Texas/Mexico border. The project is a federally funded follow-on to a project funded by the Texas State Energy Conservation Office in 2007 that developed and demonstrated initial prototype hybrid generation systems consisting of a proprietary energy storage technology, high efficiency charging and inverting systems, photovoltaic cells, a wind turbine, and bio-diesel generators. This combination of technologies provided continuous power to dwellings that are not grid connected, with a significant savings in fuel by allowing power generation at highly efficient operating conditions. The objective of this project was to complete development of the prototype systems and to finalize and engineering design; to install and operate the systems in the intended environment, and to evaluate the technical and economic effectiveness of the systems. The objectives of this project were met. This report documents the final design that was achieved and includes the engineering design documents for the system. The system operated as designed, with the system availability limited by maintenance requirements of the diesel gensets. Overall, the system achieved a 96% availability over the operation of the three deployed systems. Capital costs of the systems were dependent upon both the size of the generation system and the scope of the distribution grid, but, in this instance, the systems averaged $0.72/kWh delivered. This cost would decrease significantly as utilization of the system increased. The system with the highest utilization achieved a capitol cost amortized value of $0.34/kWh produced. The average amortized fuel and maintenance cost was $0.48/kWh which was dependent upon the amount of maintenance required by the diesel generator. Economically, the system is difficult to justify as an alternative to grid power. However, the operational costs are reasonable if grid power is unavailable, e.g. in a remote area or in a disaster recovery situation. In fact, avoided fuel costs for the smaller of the systems in use during this project would have a payback of the capital costs of that system in 2.3 years, far short of the effective system life.

Introduction to Distributed Generation and the CERTS Microgrid Introduction to Distributed Generation and the CERTS Microgrid Speaker(s): Chris Marnay Date: December 3, 2002 - 12:00pm Location: Bldg. 90 Seminar Host/Point of Contact: Kristina LaCommare This is a first in a series of at least 5 seminars around the winter break to survey Distributed Energy Resources (DER) research questions and various Berkeley capabilities available to address them. The electricity industry in industrialized countries may be about to reverse a century long trend towards ever larger scale, ever more centrally controlled power systems. The emergence of technologies that are competitive at small scales, close to loads, in large part because of the opportunities created to capture waste heat and locally control power quality might signal a radical

Microgrids and Heterogeneous Security, Quality, Reliability, and Availability  

E-Print Network (OSTI)

Abstract--This paper describes two stylized alternative visions in popular currency of how the power system might evolve to meet future requirements for the high quality electricity service that modern digital economies demand, a supergrids paradigm and a dispersed paradigm. Some of the economics of the dispersed vision are explored. Economic perspectives are presented on both the choice of homogeneous universal power quality upstream in the electricity supply, and also on the extremely heterogeneous requirements of end-use loads. Finally, the potential role of microgrids in delivering heterogeneous power quality is demonstrated by reference to two ongoing microgrid tests in the U.S. and Japan. • Index Terms--cogeneration, dispersed storage and generation, power quality, power system economics I.

Distributed control for optimal reactive power compensation in smart microgrids  

E-Print Network (OSTI)

We consider the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid. We first propose an approximate model for the power distribution network, which allows us to cast the problem into the class of convex quadratic, linearly constrained, optimization problems. We also show how this model provides the tools for a distributed approach, in which agents have a partial knowledge of the problem parameters and state, and can only perform local measurements. Then, we design a randomized, gossip-like optimization algorithm, providing conditions for convergence together with an analytic characterization of the convergence speed. The analysis shows that the best performance can be achieved when we command cooperation among agents that are neighbors in the smart microgrid topology. Numerical simulations are included to validate the proposed model and to confirm the analytic results about the performance of the proposed algorithm.

Microgrids in the Evolving Electricity Generation and DeliveryInfrastructure  

Science Conference Proceedings (OSTI)

The legacy paradigm for electricity service in most of the electrified world today is based on the centralized generation-transmission-distribution infrastructure that evolved under a regulated environment. More recently, a quest for effective economic investments, responsive markets, and sensitivity to the availability of resources, has led to various degrees of deregulation and unbundling of services. In this context, a new paradigm is emerging wherein electricity generation is intimately embedded with the load in microgrids. Development and decay of the familiar macrogrid is discussed. Three salient features of microgrids are examined to suggest that cohabitation of micro and macro grids is desirable, and that overall energy efficiency can be increased, while power is delivered to loads at appropriate levels of quality.

Siddiqui, Chris Marnay, Nicholas DeForest, Ana Barbosa-Póvoa, and Paulo Ferrão Journal Journal of Electric Power Systems Research Volume 103 Pagination 61-69 Date Published 06/2013 Abstract This paper describes the introduction of stochastic linear programming into Operations DER-CAM, a tool used to obtain optimal operating schedules for a given microgrid under local economic and environmental conditions. This application follows previous work on optimal scheduling of a lithium-iron-phosphate battery given the output uncertainty of a 1 MW molten carbonate fuel cell. Both are in the Santa Rita Jail microgrid, located in Dublin, California. This fuel cell has proven unreliable, partially justifying the consideration of storage options. Several stochastic DER-CAM runs are executed to compare different scenarios to values obtained by a deterministic approach. Results indicate that using a stochastic approach provides a conservative yet more lucrative battery schedule. Lower expected energy bills result, given fuel cell outages, in potential savings exceeding 6%.

A Green Prison: The Santa Rita Jail Campus Microgrid  

Science Conference Proceedings (OSTI)

A large microgrid project is nearing completion at Alameda County’s twenty-two-year-old 45 ha 4,000-inmate Santa Rita Jail, about 70 km east of San Francisco. Often described as a green prison, it has a considerable installed base of distributed energy resources (DER) including an eight-year old 1.2 MW PV array, a five-year old 1 MW fuel cell with heat recovery, and considerable efficiency investments. A current US$14 M expansion adds a 2 MW-4 MWh Li-ion battery, a static disconnect switch, and various controls upgrades. During grid blackouts, or when conditions favor it, the Jail can now disconnect from the grid and operate as an island, using the on-site resources described together with its back-up diesel generators. In other words, the Santa Rita Jail is a true microgrid, or ?grid, because it fills both requirements, i.e. it is a locally controlled system, and it can operate both grid connected and islanded. The battery’s electronics includes Consortium for Electric Reliability Technology (CERTS) Microgrid technology. This enables the battery to maintain energy balance using droops without need for a fast control system.

SciTech Connect

This study assesses the technical, environmental and economic factors affecting the application of the High Temperature Gas-Cooled Thermal Reactor (HTR) to: synthetic fuel production; and displacement of fossil fuels in other industrial and chemical processes. Synthetic fuel application considered include coal gasification, direct coal liquefaction, oil shale processing, and the upgrading of syncrude to motor fuel. A wide range of other industrial heat applications was also considered, with emphasis on the use of the closed-loop thermochemical energy pipeline to supply heat to dispersed industrial users. In this application syngas (H/sub 2/ +CO/sub 2/) is produced at the central station HTR by steam reforming and the gas is piped to individual methanators where typically 1000/sup 0/F steam is generated at the industrial user sites. The products of methanation (CH/sub 4/ + H/sub 2/O) are piped back to the reformer at the central station HTR.

The CERTS microgrid and the future of the macrogrid  

Science Conference Proceedings (OSTI)

The blackouts of summer 2003 underscored the dependence of western economies on reliable supply of electricity with tight tolerances of quality. While demand for electricity continues to grow, expansion of the traditional electricity supply system is constrained and is unlikely to keep pace with the growing thirst western economies have for electricity. Furthermore, no compelling case has been made that perpetual improvement in the overall power quality and reliability (PQR) delivered is possible or desirable. An alternative path to providing for sensitive loads is to provide for generation close to them. This would alleviate the pressure for endless improvement in grid PQR and might allow the establishment of a sounder economically based level of universal grid service. Providing for loads by means of local power generation is becoming increasingly competitive with central station generation for a number of reasons, four key ones being non-technical constraints on expansion of the grid, improvements in small scale technologies, opportunities for CHP application, and the ubiquitous nature of sensitive loads in advanced economies. Along with these new technologies, concepts for operating them partially under local control in microgrids are emerging, the CERTS Microgrid being one example. It has been demonstrated in simulation, and a laboratory test of a three microturbine system is planned for early 2005, to be followed by a field demonstration. A systemic energy analysis of a southern California naval base building demonstrates a current economic on-site power opportunity.

Integration& Operation of a Microgrid at Santa Rita Jail  

DOE Green Energy (OSTI)

Santa Rita Jail is a 4,500 inmate facility located in Dublin CA, approximately 40 miles (65 km) east of San Francisco. Over the past decade, a series of Distributed Energy Resources (DER) installations and efficiency measures have been undertaken to transform the 3MW facility into a"Green Jail". These include a 1.2MW rated rooftop PV system installed in 2002, a 1MW molten carbonate fuel cell with CHP, and retrofits to lighting and HVAC systems to reduce peak loads. With the upcoming installation of a large-scale battery and fast static disconnect switch, Santa Rita Jail will become a true microgrid, with full CERTS Microgrid functionality. Consequently, the jail will be able to seamlessly disconnect from the grid and operate as an island in the event of a disturbance, reconnecting again once the disturbance has dissipated. The extent to which that jail is capable of islanding is principally dependant on the energy capacity of the battery-one focus of this investigation. Also presented here are overviews of the DER currently installed at the jail, as well as the value it provides by offsetting the purchase of electricity under the current Pacific Gas& Electric (PG&E) tariff.

Microgrids are small power systems that can operate independently of the bulk power system. They are composed of one or more distributed resources (DR) and electrical loads that are interconnected by a distribution system. Most of today's microgrids are fairly simple in design, consisting of a single generator supplying a dedicated load or of multiple identical generating units ganged to operate much like a single unit. This report addresses technical issues involved when dissimilar generators are used.

International Conference on Climate Change Adaptation Assessments: Conference summary and statement  

SciTech Connect

The International Conference on Climate Change Adaptation Assessments was held in St. Petersburg, Russian Federation, from May 22--25, 1995. Sponsored by the Russian Federal Service for Hydrometeorology and Environmental Monitoring, the US Country Studies Program, and the directorate General for International Cooperation of the Netherlands Government, it was the first international conference focusing exclusively on adaptation to climate change. More than 100 people from 29 countries on five continents participated. The conference primarily addressed measures to anticipate the potential effects of climate change to minimize negative effects and take advantage of any positive effects. The focus was on what governments, institutions, and individuals can do to prepare for climate change. The conference dealt with two major topics: What adaptation options are most effective and efficient in anticipating climate change and what methods should be used to assess the effectiveness and efficiency of adaptation options. Brief summaries are given from the following sessions on agriculture; Water resources; coastal resources; ecosystems and forests; fisheries; human settlements; water and agriculture; and the panel session on international adaptation in national communications and other development plans and needs for technical assistance.

Integration of distributed energy resources. The CERTS Microgrid Concept  

DOE Green Energy (OSTI)

Evolutionary changes in the regulatory and operational climate of traditional electric utilities and the emergence of smaller generating systems such as microturbines have opened new opportunities for on-site power generation by electricity users. In this context, distributed energy resources (DER)--small power generators typically located at users' sites where the energy (both electric and thermal) they generate is used--have emerged as a promising option to meet growing customer needs for electric power with an emphasis on reliability and power quality. The portfolio of DER includes generators, energy storage, load control, and, for certain classes of systems, advanced power electronic interfaces between the generators and the bulk power provider. This white paper proposes that the significant potential of smaller DER to meet customers' and utilities' needs can be best captured by organizing these resources into MicroGrids.

Optimization and Control of Cooling Microgrids for Data Centers  

E-Print Network (OSTI)

Abstract — Reliable operation of today’s data centers requires a tremendous amount of electricity to power both the IT equipment and the supporting cooling facilities. As much as half of total data center electricity consumption can be attributed to the cooling systems required to maintain the thermal status of IT equipment. In order to lower the electricity usage of the cooling system and hence reduce the data center environmental footprint, alternative cooling resources, such as water and air-side economizers, are being exploited to supplement or replace the traditional chilled water based cooling schemes. The various cooling resource options, together with the mechanisms to distribute and deliver the cooling resource to IT equipment racks, constitute a cooling microgrid. In this paper, we present a holistic perspective for the optimization and control of the data

Design and Performance of Solar Decathlon 2011 High-Penetration Microgrid: Preprint  

DOE Green Energy (OSTI)

The U.S. Department of Energy Solar Decathlon challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. The Solar Decathlon 2011 was held in Washington, D.C., from September 23 to October 2, 2011 . A high-penetration microgrid was designed, installed, and operated for the Solar Decathlon 2011 to grid-connect 19 highly energy-efficient, solar-powered competition houses to a single utility connection point. The capacity penetration of this microgrid (defined as maximum PV generation divided by maximum system load over a two-week period) was 74% based on 1-minute averaged data. Temporary, ground-laid conductors and electrical distribution equipment were installed to grid-connect the Solar Decathlon village, which included the houses as well as other electrical loads used by the event organizers. While 16 of the houses were connected to the 60 Hz microgrid, three houses from Belgium, China, and New Zealand were supplied with 50 Hz power. The design of the microgrid, including the connection of the houses powered by 50 Hz and a standby diesel generator, is discussed in this paper. In addition to the utility-supplied net energy meters at each house, a microgrid monitoring system was installed to measure and record energy consumption and PV energy production at 1-second intervals at each house. Bidirectional electronic voltage regulators were installed for groups of competition houses, which held the service voltage at each house to acceptable levels. The design and successful performance of this high-penetration microgrid is presented from the house, microgrid operator, and utility perspectives.

A Framework for the Evaluation of the Cost and Benefits of Microgrids  

DOE Green Energy (OSTI)

A Microgrid is recognized as an innovative technology to help integrate renewables into distribution systems and to provide additional benefits to a variety of stakeholders, such as offsetting infrastructure investments and improving the reliability of the local system. However, these systems require additional investments for control infrastructure, and as such, additional costs and the anticipated benefits need to be quantified in order to determine whether the investment is economically feasible. This paper proposes a methodology for systematizing and representing benefits and their interrelationships based on the UML Use Case paradigm, which allows complex systems to be represented in a concise, elegant format. This methodology is demonstrated by determining the economic feasibility of a Microgrid and Distributed Generation installed on a typical Canadian rural distribution system model as a case study. The study attempts to minimize the cost of energy served to the community, considering the fixed costs associated with Microgrids and Distributed Generation, and suggests benefits to a variety of stakeholders.

Control Strategies for Distributed Energy Resources to Maximize the Use of Wind Power in Rural Microgrids  

Science Conference Proceedings (OSTI)

The focus of this paper is to design control strategies for distributed energy resources (DERs) to maximize the use of wind power in a rural microgrid. In such a system, it may be economical to harness wind power to reduce the consumption of fossil fuels for electricity production. In this work, we develop control strategies for DERs, including diesel generators, energy storage and demand response, to achieve high penetration of wind energy in a rural microgrid. Combinations of centralized (direct control) and decentralized (autonomous response) control strategies are investigated. Detailed dynamic models for a rural microgrid are built to conduct simulations. The system response to large disturbances and frequency regulation are tested. It is shown that optimal control coordination of DERs can be achieved to maintain system frequency while maximizing wind power usage and reducing the wear and tear on fossil fueled generators.

Game Theoretic Approach for Elastic and Inelastic Demand Management in Microgrid  

E-Print Network (OSTI)

Smart grid, which consists of many small microgrids, leads to a more stable and secure grid. In this paper, we proposed a game theoretic approach using a novel combinational pricing signal for the demand side management in a microgrid. We classified the appliance in a smart grid into appliance with elastic energy demand and appliance with inelastic appliance. We use game-theoretic approach to analyze the interaction between the microgrid operator and end users as well as among end users themself. We formulate the problem as a single leader, multiple followers Stackelberg game. An unique Stackelberg-Nash equilibrium is derived under two-fold pricing at first and then extended to case of uniform pricing scheme. 1

Smart Energy Management and Control for Fuel Cell Based Micro-Grid Connected Neighborhoods  

DOE Green Energy (OSTI)

Fuel cell power generation promises to be an efficient, pollution-free, reliable power source in both large scale and small scale, remote applications. DOE formed the Solid State Energy Conversion Alliance with the intention of breaking one of the last barriers remaining for cost effective fuel cell power generation. The Alliance’s goal is to produce a core solid-state fuel cell module at a cost of no more than $400 per kilowatt and ready for commercial application by 2010. With their inherently high, 60-70% conversion efficiencies, significantly reduced carbon dioxide emissions, and negligible emissions of other pollutants, fuel cells will be the obvious choice for a broad variety of commercial and residential applications when their cost effectiveness is improved. In a research program funded by the Department of Energy, the research team has been investigating smart fuel cell-operated residential micro-grid communities. This research has focused on using smart control systems in conjunction with fuel cell power plants, with the goal to reduce energy consumption, reduce demand peaks and still meet the energy requirements of any household in a micro-grid community environment. In Phases I and II, a SEMaC was developed and extended to a micro-grid community. In addition, an optimal configuration was determined for a single fuel cell power plant supplying power to a ten-home micro-grid community. In Phase III, the plan is to expand this work to fuel cell based micro-grid connected neighborhoods (mini-grid). The economic implications of hydrogen cogeneration will be investigated. These efforts are consistent with DOE’s mission to decentralize domestic electric power generation and to accelerate the onset of the hydrogen economy. A major challenge facing the routine implementation and use of a fuel cell based mini-grid is the varying electrical demand of the individual micro-grids, and, therefore, analyzing these issues is vital. Efforts are needed to determine the most appropriate means of implementing micro-grids and the costs and processes involved with their extended operation. With the development and availability of fuel cell based stand-alone power plants, an electrical mini-grid, encompassing several connected residential neighborhoods, has become a viable concept. A primary objective of this project is to define the parameters of an economically efficient fuel cell based mini-grid. Since pure hydrogen is not economically available in sufficient quantities at the present time, the use of reforming technology to produce and store excess hydrogen will also be investigated. From a broader perspective, the factors that bear upon the feasibility of fuel cell based micro-grid connected neighborhoods are similar to those pertaining to the electrification of a small town with a localized power generating station containing several conventional generating units. In the conventional case, the town or locality would also be connected to the larger grid system of the utility company. Therefore, in the case of the fuel cell based micro-grid connected neighborhoods, this option should also be available. The objectives of this research project are: To demonstrate that smart energy management of a fuel cell based micro-grid connected neighborhood can be efficient and cost-effective;To define the most economical micro-grid configuration; and, To determine how residential micro-grid connected fuel cell(s) can contribute to America's hydrogen energy future.

Analysis of electric vehicle interconnection with commercial building microgrids  

Science Conference Proceedings (OSTI)

The outline of this presentation is: (1) global concept of microgrid and electric vehicle (EV) modeling; (2) Lawrence Berkeley National Laboratory's Distributed Energy Resources Customer Adoption Model (DER-CAM); (3) presentation summary - how does the number of EVs connected to the building change with different optimization goals (cost versus CO{sub 2}); (3) ongoing EV modeling for California: the California commercial end-use survey (CEUS) database, objective: 138 different typical building - EV connections and benefits; (4) detailed analysis for healthcare facility: optimal EV connection at a healthcare facility in southern California; and (5) conclusions. Conclusions are: (1) EV Charging/discharging pattern mainly depends on the objective of the building (cost versus CO{sub 2}); (2) performed optimization runs show that stationary batteries are more attractive than mobile storage when putting more focus on CO{sub 2} emissions. Why? Stationary storage is available 24 hours a day for energy management - more effective; (3) stationary storage will be charged by PV, mobile only marginally; (4) results will depend on the considered region and tariff - final work will show the results for 138 different buildings in nine different climate zones and three major utility service territories.

Internal cycle modeling and environmental assessment of multiple cycle consumer products  

Science Conference Proceedings (OSTI)

Highlights: Black-Right-Pointing-Pointer Dynamic flow models are presented for remanufactured, reused or recycled products. Black-Right-Pointing-Pointer Early loss and stochastic return are included for fast and slow cycling products. Black-Right-Pointing-Pointer The reuse-to-input flow ratio (Internal Cycle Factor, ICF) is determined. Black-Right-Pointing-Pointer The cycle rate, which is increasing with the ICF, monitors eco-performance. Black-Right-Pointing-Pointer Early internal cycle losses diminish the ICF, the cycle rate and performance. - Abstract: Dynamic annual flow models incorporating consumer discard and usage loss and featuring deterministic and stochastic end-of-cycle (EOC) return by the consumer are developed for reused or remanufactured products (multiple cycle products, MCPs), including fast and slow cycling, short and long-lived products. It is shown that internal flows (reuse and overall consumption) increase proportionally to the dimensionless internal cycle factor (ICF) which is related to environmental impact reduction factors. The combined reuse/recycle (or cycle) rate is shown capable for shortcut, albeit effective, monitoring of environmental performance in terms of waste production, virgin material extraction and manufacturing impacts of all MCPs, a task, which physical variables (lifetime, cycling frequency, mean or total number of return trips) and conventional rates, via which environmental policy has been officially implemented (e.g. recycling rate) cannot accomplish. The cycle rate is shown to be an increasing (hyperbolic) function of ICF. The impact of the stochastic EOC return characteristics on total reuse and consumption flows, as well as on eco-performance, is assessed: symmetric EOC return has a small, positive effect on performance compared to deterministic, while early shifted EOC return is more beneficial. In order to be efficient, environmental policy should set higher minimum reuse targets for higher trippage MCPs. The results may serve for monitoring, flow accounting and comparative eco-assessment of MCPs. They may be useful in identifying reachable and efficient reuse/recycle targets for consumer products and in planning return via appropriate labelling and digital coding for enhancing environmental performance, while satisfying consumer demand.

Effects of a carbon tax on microgrid combined heat and power adoption  

Science Conference Proceedings (OSTI)

This paper describes the economically optimal adoption and operation of distributed energy resources (DER) by a hypothetical California microgrid consisting of a group of commercial buildings over an historic test year, 1999. The optimization is conducted using a customer adoption model (DER-CAM) developed at Berkeley Lab and implemented in the General Algebraic Modeling System (GAMS). A microgrid is a semiautonomous grouping of electricity and heat loads interconnected to the existing utility grid (macrogrid) but able to island from it. The microgrid minimizes the cost of meeting its energy requirements (consisting of both electricity and heat loads) by optimizing the installation and operation of DER technologies while purchasing residual energy from the local combined natural gas and electricity utility. The available DER technologies are small-scale generators (microgrid is allowed to install CHP-enabled DER technologies, its carbon emissions are mitigated more than without CHP, demonstrating the potential benefits of small-scale CHP technology for climate change mitigation. Reciprocating engines with heat recovery and/or absorption cooling tend to be attractive technologies for the mild southern California climate, but the carbon mitigation tends to be modest compared to purchasing utility electricity because of the predominance of relatively clean central station generation in California.

Effects of a carbon tax on microgrid combined heat and power adoption

This paper describes the economically optimal adoption and operation of distributed energy resources (DER) by a hypothetical California microgrid consisting of a group of commercial buildings over an historic test year, 1999. The optimization is conducted using a customer adoption model (DER-CAM) developed at Berkeley Lab and implemented in the General Algebraic Modeling System (GAMS). A microgrid is a semiautonomous grouping of electricity and heat loads interconnected to the existing utility grid (macrogrid) but able to island from it. The microgrid minimizes the cost of meeting its energy requirements (consisting of both electricity and heat loads) by optimizing the installation and operation of DER technologies while purchasing residual energy from the local combined natural gas and electricity utility. The available DER technologies are small-scale generators (< 500 kW), such as reciprocating engines, microturbines, and fuel cells, with or without combined heat and power (CHP) equipment, such as water and space heating and/or absorption cooling. By introducing a tax on carbon emissions, it is shown that if the microgrid is allowed to install CHP-enabled DER technologies, its carbon emissions are mitigated more than without CHP, demonstrating the potential benefits of small-scale CHP technology for climate change mitigation. Reciprocating engines with heat recovery and/or absorption cooling tend to be attractive technologies for the mild southern California climate, but the carbon mitigation tends to be modest compared to purchasing utility electricity because of the predominance of relatively clean central station generation in California.

Vehicle to Micro-Grid: Leveraging Existing Assets for Reliable Energy Management (Poster)  

DOE Green Energy (OSTI)

Fort Carson, a United States Army installation located south of Colorado Springs, Colorado, is seeking to be a net-zero energy facility. As part of this initiative, the base will be constructing a micro-grid that ties to various forms of renewable energy. To reduce petroleum consumption, Fort Carson is considering grid-connected vehicles (GCVs) such as pure electric trucks to replace some of its on-base truck fleet. As the availability and affordability of distributed renewable energy generation options increase, so will the GCV options (currently, three all-electric trucks are available on the GSA schedule). The presence of GCVs on-base opens up the possibility to utilize these vehicles to provide stability to the base micro-grid. This poster summarizes work to estimate the potential impacts of three electric vehicle grid interactions between the electric truck fleet and the Fort Carson micro-grid: 1) full-power charging without management, 2) full-power charging capability controlled by the local grid authority, and 3) full-power charge and discharge capability controlled by the local grid authority. We found that even at relatively small adoption rates, the control of electric vehicle charging at Fort Carson will aid in regulation of variable renewable generation loads and help stabilize the micro-grid.

A Micro-Grid Simulator Tool (SGridSim) using Effective Node-to-Node Complex Impedance (EN2NCI) Models  

SciTech Connect

This paper presents a micro-grid simulator tool useful for implementing and testing multi-agent controllers (SGridSim). As a common engineering practice it is important to have a tool that simplifies the modeling of the salient features of a desired system. In electric micro-grids, these salient features are the voltage and power distributions within the micro-grid. Current simplified electric power grid simulator tools such as PowerWorld, PowerSim, Gridlab, etc, model only the power distribution features of a desired micro-grid. Other power grid simulators such as Simulink, Modelica, etc, use detailed modeling to accommodate the voltage distribution features. This paper presents a SGridSim micro-grid simulator tool that simplifies the modeling of both the voltage and power distribution features in a desired micro-grid. The SGridSim tool accomplishes this simplified modeling by using Effective Node-to-Node Complex Impedance (EN2NCI) models of components that typically make-up a micro-grid. The term EN2NCI models means that the impedance based components of a micro-grid are modeled as single impedances tied between their respective voltage nodes on the micro-grid. Hence the benefit of the presented SGridSim tool are 1) simulation of a micro-grid is performed strictly in the complex-domain; 2) faster simulation of a micro-grid by avoiding the simulation of detailed transients. An example micro-grid model was built using the SGridSim tool and tested to simulate both the voltage and power distribution features with a total absolute relative error of less than 6%.

The MicroGrid: a Scientific Tool for Modeling Computational Grids  

E-Print Network (OSTI)

The complexity and dynamic nature of the Internet (and the emerging Computational Grid) demand that middleware and applications adapt to the changes in configuration and availability of resources. However, to the best of our knowledge there are no simulation tools which support systematic exploration of dynamic Grid software (or Grid resource) behavior. We describe our vision and initial efforts to build tools to meet these needs. Our MicroGrid simulation tools enable Globus applications to be run in arbitrary virtual grid resource environments, enabling broad experimentation. We describe the design of these tools, and their validation on microbench marks, the NAS parallel benchmarks, and an entire Grid application. These validation experiments show that the MicroGrid can match actual experiments within a few percent (2% to 4%).

Added Value of Reliability to a Microgrid: Simulations of Three California Buildings  

Science Conference Proceedings (OSTI)

The Distributed Energy Resources Customer Adoption Model is used to estimate the value an Oakland nursing home, a Riverside high school, and a Sunnyvale data center would need to put on higher electricity service reliability for them to adopt a Consortium for Electric Reliability Technology Solutions Microgrid (CM) based on economics alone. A fraction of each building's load is deemed critical based on its mission, and the added cost of CM capability to meet it added to on-site generation options. The three sites are analyzed with various resources available as microgrid components. Results show that the value placed on higher reliability often does not have to be significant for CM to appear attractive, about 25 $/kWcdota and up, but the carbon footprint consequences are mixed because storage is often used to shift cheaper off-peak electricity to use during afternoon hours in competition with the solar sources.

The MicroGrid: Using Emulation to Predict Application Performance in Diverse Grid Network Environments  

E-Print Network (OSTI)

Improvements in networking and middleware technology are enabling large-scale grids that aggregate resources over wide-area networks to support applications at unprecedented levels of scale and performance. Unfortunately, existing middleware and tools can not in general inform a user as to the suitability of a given grid topology for a specific grid application. Instead, users generally develop ad hoc performance models for mapping their applications to resource and network topologies. Because application behavior alone is complex, and resource and network behavior further complicate the picture, users are typically reduced to nearly blind experimentation to discover how to deploy their application in the new grid environment. Only after the fact can a user discovers if the match was a good one. Further, even after finding a desirable configuration, there is no basis on which to determine if a much better configuration exists. We present a richer methodology for evaluating grid software and diverse grid environments based on the MicroGrid grid emulator. With the MicroGrid, users, grid researchers, or grid operators can define and emulate arbitrary collections of resources and networks. This allows study of an existing grid testbed under controlled conditions or even to study the efficacy of higher performance environments than are available today. Further, the MicroGrid supports direct execution of grid applications unchanged. These application can be written with MPI, C, C++, Perl, and/or Python and use the Globus middleware. This enables detailed and accurate study of application behavior.

Online energy generation scheduling for microgrids with intermittent energy sources and cogeneration. arXiv preprint arXiv:1211.4473  

E-Print Network (OSTI)

Microgrids represent an emerging paradigm of future electric power systems that can utilize both distributed and centralized generations. Two recent trends in microgrids are the integration of local renewable energy sources (such as wind farms) and the use of co-generation (i.e., to supply both electricity and heat). However, these trends also bring unprecedented challenges to the design of intelligent control strategies for microgrids. Traditional generation scheduling paradigms rely on perfect prediction of future electricity supply and demand. They are no longer applicable to microgrids with unpredictable renewable energy supply and with co-generation (that needs to consider both electricity and heat demand). In this paper, we study online algorithms for the microgrid generation scheduling problem with intermittent

Tank waste remediation system retrieval and disposal mission readiness-to-proceed responses to internal independent assessment  

SciTech Connect

The US Department of Energy (DOE) is planning to make critical decisions during fiscal year (FY) 1998 regarding privatization contracts for the treatment of Hanford tank waste. Specifically, DOE, Richland Operations Office (RL), will make decisions related to proceeding with Phase 1 Privatization. In support of these decisions, the management and integration (M+I) contractor must be able to meet the requirements to support the Phase 1 privatization contractors. As part of the assessment of the Tank Waste Retrieval (TWR) Readiness-To-Proceed (RTP), an independent review of their process and products was required by the RL letter of August 8, 1997. The Independent Review Team reviewed the adequacy of the planning that has been done by the M+I contractor to validate that, if the plans are carried out, there is reasonable assurance of success. Overall, the RTP Independent Review Team concluded that, if the planning by the M+I contractor team is carried out with adequate funding, there is reasonable assurance that the M+I contractor will be able to deliver waste to the privatization contractor for the duration of Phase 1. This conclusion was based on addressing the recommendations contained in the Independent Review Team`s Final Report and in the individual Criteria and Review Approach (CRA) forms completed during the assessment. The purpose of this report is to formally document the independent assessment and the RTP team responses to the Independent Review Team recommendations. It also provides closure logics for selected recommendations from a Lockheed Martin Hanford Corporation (LMHC) internal assessment of the Technical Basis Review (TBR) packages. This report contains the RTP recommendation closure process (Section 2.0); the closure tables (Section 3.0) which provide traceability between each review team recommendation and its corresponding Project Hanford Management Contract closure logic; and two attachments that formally document the Independent Review Team Final Report and the Internal Assessment Final Report.

Assessment of PWR Steam Generator modelling in RELAP5/MOD2. International Agreement Report  

SciTech Connect

An assessment of Steam Generator (SG) modelling in the PWR thermal-hydraulic code RELAP5/MOD2 is presented. The assessment is based on a review of code assessment calculations performed in the UK and elsewhere, detailed calculations against a series of commissioning tests carried out on the Wolf Creek PWR and analytical investigations of the phenomena involved in normal and abnormal SG operation. A number of modelling deficiencies are identified and their implications for PWR safety analysis are discussed -- including methods for compensating for the deficiencies through changes to the input deck. Consideration is also given as to whether the deficiencies will still be present in the successor code RELAP5/MOD3.

Probabilistic accident consequence uncertainty analysis -- Uncertainty assessment for internal dosimetry. Volume 2: Appendices  

Science Conference Proceedings (OSTI)

The development of two new probabilistic accident consequence codes, MACCS and COSYMA, was completed in 1990. These codes estimate the consequence from the accidental releases of radiological material from hypothesized accidents at nuclear installations. In 1991, the US Nuclear Regulatory Commission and the Commission of the European Communities began cosponsoring a joint uncertainty analysis of the two codes. The ultimate objective of this joint effort was to systematically develop credible and traceable uncertainty distributions for the respective code input variables. A formal expert judgment elicitation and evaluation process was identified as the best technology available for developing a library of uncertainty distributions for these consequence parameters. This report focuses on the results of the study to develop distribution for variables related to the MACCS and COSYMA internal dosimetry models. This volume contains appendices that include (1) a summary of the MACCS and COSYMA consequence codes, (2) the elicitation questionnaires and case structures, (3) the rationales and results for the panel on internal dosimetry, (4) short biographies of the experts, and (5) the aggregated results of their responses.

A preliminary assessment of Steam Generator (SG) modelling in the PWR thermal-hydraulic code RELAP5/MOD3 is presented. The study is based on calculations against a series of steady-state commissioning tests carried out on the Wolf Creek PWR over a range of load conditions. Data from the tests are used to assess the modelling of primary to secondary side heat transfer and, in particular, to examine the effect of reverting to the standard form of the Chen heat transfer correlation in place of the modified form applied in RELAP5/MOD2. Comparisons between the two versions of the code are also used to show how the new interphase drag model in RELAP5/MOD3 affects the calculation of SG liquid inventory and the void fraction profile in the riser.

The Lisbon new international airport: The story of a decision-making process and the role of Strategic Environmental Assessment  

SciTech Connect

This is the brief story of a decision process and the role of Strategic Environmental Assessment in government political decision-making. Following a prolonged, and agitated, decision process, initiated in the 1960s, the Government of Portugal in 2005 took the final decision to build the new international airport of Lisbon at the controversial location of Ota, 40 km north of Lisbon. The detailed project design and EIA were started. However this decision would change in 2007 due to the challenge raised by a private sponsored study that identified an alternative location for the airport at Campo de Tiro de Alcochete (CTA). This new site, which had never been considered as an option before, appeared to avoid many of the problems that caused public controversy at the Ota site. The Government, pressured by this challenge, promoted a strategic comparative assessment between the two sites. The result of this study was the choice of CTA as the preferred location. This paper discusses this radical change in the decision from a socio-political perspective. It will highlight the relevance of Strategic Environmental Assessment (SEA), and the strategic and constructive approach it enables in mega-project decision-making.

Health impact assessment: A comparison of 45 local, national, and international guidelines  

SciTech Connect

This article provides a comparison of health impact assessment (HIA) guidelines from around the world and for multiple geographic scales. We identify commonalities and differences within HIA guides to discuss the plausibility of consensus guidelines and to inform guideline development. The practice of HIA has grown over the last two decades with a concurrent growth of HIA guides. This study expands on earlier review work and includes guides published since 2007 (Mindell, Boltong and Forde, 2008). From April 2010 to October 2011, 45 HIA guides were identified through an internet search and review of previous research. Common characteristics, key features, and the HIA process were analyzed. The 45 documents recommended similar but not identical processes for conducting HIAs. These analyses suggest that guidelines for HIAs are similar in many areas of the world and that new HIA practitioners can use these findings to inform their approach. Further discussion is needed to determine if the approaches established in these guidelines are followed and if one set of common guidelines could be written for use in numerous countries and regions. - Highlights: Black-Right-Pointing-Pointer We analyze 45 health impact assessment (HIA) guidelines worldwide. Black-Right-Pointing-Pointer We examine similarities and unique attributes of each guideline. Black-Right-Pointing-Pointer We discuss the advantages and disadvantages of developing consensus guidelines.

Assessing Foundation Insulation Strategies for the 2012 International Energy Conservation Code in Cold Climate New Home Construction  

SciTech Connect

While the International Energy Conservation Code 2012 (IECC 2012) has been adopted at a national level, only two cold climate states have adopted it as their new home energy code. Understanding the resistance to adoption is important in assisting more states accept the code and engage deep energy strategies nationwide. This three-part assessment by the NorthernSTAR Building America Partnership was focused on foundation insulation R-values for cold climates and the design, construction, and performance implications. In Part 1 a literature review and attendance at stakeholder meetings held in Minnesota were used to assess general stakeholder interest and concerns regarding proposed code changes. Part 2 includes drawings of robust foundation insulation systems that were presented at one Minnesota stakeholder meeting to address critical issues and concerns for adopting best practice strategies. In Part 3 a sampling of builders participated in a telephone interview to gain baseline knowledge on insulation systems used to meet the current energy code and how the same builders propose to meet the new proposed code.

Decoding the `Nature Encoded' Messages for Distributed Energy Generation Control in Microgrid  

E-Print Network (OSTI)

The communication for the control of distributed energy generation (DEG) in microgrid is discussed. Due to the requirement of realtime transmission, weak or no explicit channel coding is used for the message of system state. To protect the reliability of the uncoded or weakly encoded messages, the system dynamics are considered as a `nature encoding' similar to convolution code, due to its redundancy in time. For systems with or without explicit channel coding, two decoding procedures based on Kalman filtering and Pearl's Belief Propagation, in a similar manner to Turbo processing in traditional data communication systems, are proposed. Numerical simulations have demonstrated the validity of the schemes, using a linear model of electric generator dynamic system.

On-chip COMA cache-coherence protocol for microgrids of microthreaded cores  

E-Print Network (OSTI)

This paper describes an on-chip COMA cache coherency protocol to support the microthread model of concurrent program composition. The model gives a sound basis for building multi-core computers as it captures concurrency, abstracts communication and identifies resources, such as processor groups explicitly and where mapping and scheduling is performed dynamically. The result is a model where binary compatibility is guaranteed over arbitrary numbers of cores and where backward binary compatibility is also assured. We present the design of a memory system with relaxed synchronisation and consistency constraints that matches the characteristics of this model. We exploit an on-chip COMA organisation, which provides a flexible and transparent partitioning between processors and memory. This paper describes the coherency protocol and consistency model and describes work undertaken on the validation of the model and the development of a co-simulator to the Microgrid CMP emulator. 1

Enhanced photocatalytic activity of Ag microgrid connected TiO{sub 2} nanocrystalline films  

SciTech Connect

One reason for the high degree of photogenerated carrier recombination was found to be the charge accumulation caused by the uneven reaction area on the photocatalyst surface. The authors connected TiO{sub 2} nanoparticles with conducting Ag microgrid. Obvious photocatalytic activity improvement (81%) over the pure TiO{sub 2} was observed, which is attributed to the electron-hole pairs separation by the metal-semiconductor contact and the large specific area of metal grid, which increased the O{sub 2} absorption and transported the electrons to the sites needed for the deoxidize reactions. This structure lowers the electron accumulation on the particles and improves the utilization ratio of the photoexcited carriers.

Effects of a carbon tax on combined heat and power adoption by a microgrid  

DOE Green Energy (OSTI)

This paper describes the economically optimal adoption and operation of distributed energy resources (DER) by a hypothetical California microgrid ((mu)Grid) consisting of a group of commercial buildings over an historic test year, 1999. The optimization is conducted using a customer adoption model (DER-CAM) developed at Berkeley Lab and implemented in the General Algebraic Modeling System (GAMS). A (mu)Grid is a semiautonomous grouping of electricity and heat loads interconnected to the existing utility grid (macrogrid) but able to island from it. The (mu)Grid minimizes the cost of meeting its energy requirements (consisting of both electricity and heat loads) by optimizing the installation and operation of DER technologies while purchasing residual energy from the local combined natural gas and electricity utility. The available DER technologies are small-scale generators (< 500 kW), such as reciprocating engines, microturbines, and fuel cells, with or without CHP equipment, such as water- and space-heating and/or absorption cooling. By introducing a tax on carbon emissions, it is shown that if the (mu)Grid is allowed to install CHP-enabled DER technologies, its carbon emissions are mitigated more than without CHP, demonstrating the potential benefits of small-scale CHP technology for climate change mitigation. Reciprocating engines with heat recovery and/or absorption cooling tend to be attractive technologies for the mild southern California climate, but the carbon mitigation tends to be modest compared to purchasing utility electricity because of the predominance of relatively clean generation in California.

Microgrids: An emerging paradigm for meeting building electricityand heat requirements efficiently and with appropriate energyquality  

Science Conference Proceedings (OSTI)

The first major paradigm shift in electricity generation,delivery, and control is emerging in the developed world, notably Europe,North America, and Japan. This shift will move electricity supply awayfrom the highly centralised universal service quality model with which weare familiar today towards a more dispersed system with heterogeneousqualities of service. One element of dispersed control is the clusteringof sources and sinks into semi-autonomous mu grids (microgrids).Research, development, demonstration, and deployment (RD3) of mu gridsare advancing rapidly on at least three continents, and significantdemonstrations are currently in progress. This paradigm shift will resultin more electricity generation close to end-uses, often involvingcombined heat and power application for building heating and cooling,increased local integration of renewables, and the possible provision ofheterogeneous qualities of electrical service to match the requirementsof various end-uses. In Europe, mu grid RD3 is entering its third majorround under the 7th European Commission Framework Programme; in the U.S.,one specific mu grid concept is undergoing rigorous laboratory testing,and in Japan, where the most activity exists, four major publiclysponsored and two privately sponsored demonstrations are in progress.This evolution poses new challenges to the way buildings are designed,built, and operated. Traditional building energy supply systems willbecome much more complex in at least three ways: 1. one cannot simplyassume gas arrives at the gas meter, electricity at its meter, and thetwo systems are virtually independent of one another; rather, energyconversion, heat recovery and use, and renewable energy harvesting mayall be taking place simultaneously within the building energy system; 2.the structure of energy flows in the building must accommodate multipleenergy processes in a manner that permits high overall efficiency; and 3.multiple qualities of electricity may be supplied to various buildingfunctions.

Assessment of CCFL model of RELAP5/MOD3 against simple vertical tubes and rod bundle tests. International Agreement Report  

SciTech Connect

The CCFL model used in RELAP5/MOD3 version 5m5 has been assessed against simple vertical tubes and bundle tests performed at a facility of Korea Atomic Energy Research Institute. The effect of changes in tube diameter and nodalization of tube section were investigated. The roles of interfacial drags on the flooding characteristics are discussed. Differences between the calculation and the experiment are also discussed. A comparison between model assessment results and the test data showed that the calculated value lay well on the experimental flooding curve specified by user, but the pressure jump before onset of flooding was not calculated.

Use of international data sets to evaluate and validate pathway assessment models applicable to exposure and dose reconstruction at DOE facilities. Progress report, March--May 1994  

Science Conference Proceedings (OSTI)

The project described in this report was the result of a Memorandum of Cooperation between the US and the former-USSR following the accident at the Chernobyl Nuclear Power Plant Unit 4. A joint program was established to improve the safety of nuclear power plants and to understand the implications of environmental releases. The task of Working Group 7 was ``to develop jointly methods to project rapidly the health effects of any future nuclear reactor accident.`` The current objective of this project is to evaluate and validate pathway-assessment models applicable to exposure and dose reconstruction at DOE facilities through use of international data sets. This project incorporates data used for the prediction of radionuclide transfer through agricultural and aquatic systems to humans. It also includes participation in two multinational studies, BIOMOVS (Biospheric Model Validation Study) with the Swedish National Institute for Radiation Protection and VAMP (Validation of Model Predictions) with the International Atomic Energy Agency, that address testing the performance of models of radionuclide transport through foodchains. In the future, this project will be considered separately from the Chernobyl Studies Project and the essential activities of former Task 7.1D will be folded within the broader umbrella of the BIOMOVS and VAMP projects. The Working Group Leader of Task 7.1D will continue to provide oversight for this project.

The Added Economic and Environmental Value of Solar Thermal Systems in Microgrids with CombinedHeat and Power  

Science Conference Proceedings (OSTI)

The addition of solar thermal and heat storage systems can improve the economic, as well as environmental attraction of micro-generation systems, e.g. fuel cells with or without combined heat and power (CHP) and contribute to enhanced CO2 reduction. However, the interactions between solar thermal collection and storage systems and CHP systems can be complex, depending on the tariff structure, load profile, etc. In order to examine the impact of solar thermal and heat storage on CO2 emissions and annual energy costs, a microgrid's distributed energy resources (DER) adoption problem is formulated as a mixed-integer linear program. The objective is minimization of annual energy costs. This paper focuses on analysis of the optimal interaction of solar thermal systems, which can be used for domestic hot water, space heating and/or cooling, and micro-CHP systems in the California service territory of San Diego Gas and Electric (SDG&E). Contrary to typical expectations, our results indicate that despite the high solar radiation in southern California, fossil based CHP units are dominant, even with forecast 2020 technology and costs. A CO2 pricing scheme would be needed to incent installation of combined solar thermal absorption chiller systems, and no heat storage systems are adopted. This research also shows that photovoltaic (PV) arrays are favored by CO2 pricing more than solar thermal adoption.

Effect of Heat and Electricity Storage and Reliability on Microgrid Viability:A Study of Commercial Buildings in California and New York States  

Science Conference Proceedings (OSTI)

In past work, Berkeley Lab has developed the Distributed Energy Resources Customer Adoption Model (DER-CAM). Given end-use energy details for a facility, a description of its economic environment and a menu of available equipment, DER-CAM finds the optimal investment portfolio and its operating schedule which together minimize the cost of meeting site service, e.g., cooling, heating, requirements. Past studies have considered combined heat and power (CHP) technologies. Methods and software have been developed to solve this problem, finding optimal solutions which take simultaneity into account. This project aims to extend on those prior capabilities in two key dimensions. In this research storage technologies have been added as well as power quality and reliability (PQR) features that provide the ability to value the additional indirect reliability benefit derived from Consortium for Electricity Reliability Technology Solutions (CERTS) Microgrid capability. This project is intended to determine how attractive on-site generation becomes to a medium-sized commercial site if economical storage (both electrical and thermal), CHP opportunities, and PQR benefits are provided in addition to avoiding electricity purchases. On-site electrical storage, generators, and the ability to seamlessly connect and disconnect from utility service would provide the facility with ride-through capability for minor grid disturbances. Three building types in both California and New York are assumed to have a share of their sensitive electrical load separable. Providing enhanced service to this load fraction has an unknown value to the facility, which is estimated analytically. In summary, this project began with 3 major goals: (1) to conduct detailed analysis to find the optimal equipment combination for microgrids at a few promising commercial building hosts in the two favorable markets of California and New York; (2) to extend the analysis capability of DER-CAM to include both heat and electricity storage; and (3) to make an initial effort towards adding consideration of PQR into the capabilities of DER-CAM.

Internalizing the externalities of solar technology: Methodologies for incorporating externalities in the assessment of policy options and technology assessments of solar energy initiatives and R and D programs using Brookhaven models  

DOE Green Energy (OSTI)

Internalizing the costs for implementing solar energy may never be, the author says. In the meantime, budget allocation decisions must be made. It is the purpose of this paper to identify capabilities currently in existence at BNL that help to provide answers to the value of increasing the contribution of solar energy. This paper presents several alternative approaches. BNL models that are useful for the economic measurement of energy related environmental damage are NEDS/REPS1 NEDS/REPS; ESNS; PRESTO; and optimization models (M-RESOM, BECOM, SOGEPH, BESOM, DESOM/TESOM/MARICAL). The approaches suggested would be much more useful if they were evaluated by certain criteria. This is the goal of most systems research on internalizing externalities. The methods described provide quantitative measures for the following criteria, although no single method provides all of them: the residuals produced with and without solar; the impact of residuals on life, property, ecosystems, and ambience; the intergenerational effects; the effect of oil imports on security; the depletion of non-renewable resources; the quantification (as far as possible) of externalities; and the appropriate level of aggregration. In most cases in this paper, examples are given. The most common criteria is that the energy demands must be driven by an economic model that in turn is driven by an energy model that produces the energy prices and the fuel mix. Solar technology implementation is particularly dependent on relative prices, economic activity, and energy demand. (MCW)

Relevance of international research facilities to international stability  

Science Conference Proceedings (OSTI)

International Facilities have played an important play in expanding and keeping open a dialogue between east and west. The advent of glasnost has dramatically reduced inhibitions on communications and opened new opportunities for international facilities to facilitate the understanding and appreciation of common goals and common threats. This is accomplished through frank discussions in which real problems are identified and assessed while fictitious ones are laid to rest.

Derivation of a chemical-specific adjustment factor (CSAF) for use in the assessment of risk from chronic exposure to ethylene glycol: Application of international programme for chemical safety guidelines  

SciTech Connect

The International Programme for Chemical Safety (IPCS) has developed a set of guidelines ('the Guidance') for the establishment of Chemical-Specific Adjustment Factors (CSAFs) for in the assessment of toxicity risk to the human population as a result of chemical exposure. The development of case studies is encouraged in the Guidance document and comments on them have been encouraged by the IPCS. One provision in the Guidance is for the determination of CSAFs based on human data. We present a case study of the use of the Guidance for the determination of the CSAF for ethylene glycol (EG) primarily utilizing clinically obtained data. The most relevant endpoint for this analysis was deemed to be acute renal injury. These data were applied based on an assessment of the known pharmaco/toxico-kinetic properties of EG. Because of the lack of both bioaccumulation of EG and reports of chronic or progressive renal injury from EG, it was concluded that the most appropriate model of chronic exposure is one of repeated acute episodes. The most relevant exposure metric was determined to be plasma glycolate concentration. Based on a prospective human study of EG-poisoned patients, the NOAEL for glycolate was found to be 10.1 mM. This value is similar to that obtained from animal data. The application of the Guidelines to this data resulted in a CSAF of 10.24, corresponding to a daily EG dose of 43.7 mg/kg/day. In 2000, Health Canada (HC) produced an animal data-based analysis of the maximum tolerated dose of EG. The results of our analysis are compared with those of HC, and the strengths and weaknesses of these two data types related to EG are discussed.

International Clean Energy Coalition  

Science Conference Proceedings (OSTI)

In 2003, the National Association of Regulatory Utility Commissioners (NARUC) and National Energy Technology Laboratories (NETL) collaboratively established the International Clean Energy Coalition (ICEC). The coalition consisting of energy policy-makers, technologists, and financial institutions was designed to assist developing countries in forming and supporting local approaches to greenhouse gas mitigation within the energy sector. ICEC's work focused on capacity building and clean energy deployment in countries that rely heavily on fossil-based electric generation. Under ICEC, the coalition formed a steering committee consisting of NARUC members and held a series of meetings to develop and manage the workplan and define successful outcomes for the projects. ICEC identified India as a target country for their work and completed a country assessment that helped ICEC build a framework for discussion with Indian energy decisionmakers including two follow-on in-country workshops. As of the conclusion of the project in 2010, ICEC had also conducted outreach activities conducted during United Nations Framework Convention on Climate Change (UNFCCC) Ninth Conference of Parties (COP 9) and COP 10. The broad goal of this project was to develop a coalition of decision-makers, technologists, and financial institutions to assist developing countries in implementing affordable, effective and resource appropriate technology and policy strategies to mitigate greenhouse gas emissions. Project goals were met through international forums, a country assessment, and in-country workshops. This project focused on countries that rely heavily on fossil-based electric generation.

Alternative fuels assessment: The international experience  

DOE Green Energy (OSTI)

As part of this analysis, Lawrence Berkeley Laboratory (LBL) has conducted a review of the experience with alternative transport fuels outside the US. The purpose of this review is to better understand what kinds of policies and programs other countries have instituted, and what the response by consumers and the private sector has been. While the experience in other countries grows out of their unique resource, economic, and institutional conditions, it is possible to draw lessons that are useful for evaluating options to develop a flexible-fuel transportation system in the US. The programs of other countries also affect US policy and planning related to alternative fuel supplies and vehicle and conversion technology. 4 figs., 7 tabs.

Announcement Before an audit begins, we distribute an announcement letter to those who will serve as our primary audit contacts. The letter briefly outlines the preliminary audit objectives, and the general audit process. Planning Planning is the first phase of the audit. During planning, we review policies and procedures in order to gain an understanding of how work is accomplished. We typically conduct several transaction walk-throughs by tracing transactions from beginning to end. Policies, procedures, walk-throughs, and discussions with personnel enable us to identify controls and assess associated risks.

The International Energy Outlook 1998 (IEO98) presents an assessment by the Energy Information Administration (EIA) of the outlook for international energy markets through 2020. Projections in IEO98 are displaced according to six basic country groupings. The industrialized region includes projections for four individual countries -- the United States, Canada, Mexico, and Japan -- along with the subgroups Western Europe and Australasia (defined as Australia, New Zealand, and the US Territories). The developing countries are represented by four separate regional subgroups: developing Asia, Africa, Middle East, and Central and South America. China and India are represented in developing Asia. New to this year`s report, country-level projections are provided for Brazil -- which is represented in Central and South America. Eastern Europe and the former Soviet Union (EE/FSU) are considered as a separate country grouping. The report begins with a review of world trends in energy demand. Regional consumption projections for oil, natural gas, coal, nuclear power, and renewable energy (hydroelectricity, geothermal, wind, solar, and other renewables) are presented in five fuel chapters, with a review of the current status of each fuel on a worldwide basis. Summary tables of the IEO98 projections for world energy consumption, carbon emissions, oil production, and nuclear power generating capacity are provided in Appendix A. 88 figs., 77 tabs.
