The term "green power" is used to define power generated from renewable energy sources, such as wind and solar power, geothermal, hydropower and various forms of biomass. Green power marketing has the potential to expand domestic markets for renewable energy technologies by fostering greater availability of renewable electric service options in retail markets. Although renewable energy development has traditionally been limited by cost considerations, customer choice allows consumer preferences for cleaner energy sources to be reflected in market transactions. In survey after survey, customers have expressed a preference and willingness to pay more, if necessary, for cleaner energy sources. You can find more information about purchase options on our "Buying Green Power" page.

Switching power supply  

DOE Patents (OSTI)

The invention is a repratable capacitor charging, switching power supply. A ferrite transformer steps up a dc input. The transformer primary is in a full bridge configuration utilizing power MOSFETs as the bridge switches. The transformer secondary is fed into a high voltage, full wave rectifier whose output is connected directly to the energy storage capacitor. The transformer is designed to provide adequate leakage inductance to limit capacitor current. The MOSFETs are switched to the variable frequency from 20 to 50 kHz to charge a capacitor from 0.6 kV. The peak current in a transformer primary and secondary is controlled by increasing the pulse width as the capacitor charges. A digital ripple counter counts pulses and after a preselected desired number is reached an up-counter is clocked.

Switching power pulse system  

DOE Patents (OSTI)

A switching system for delivering pulses of power from a source to a load using a storage capacitor charged through a rectifier, and maintained charged to a reference voltage level by a transistor switch and voltage comparator. A thyristor is triggered to discharge the storage capacitor through a saturable reactor and fractional turn saturable transformer having a secondary to primary turn ratio N of n:l/n = n[sup 2]. The saturable reactor functions as a soaker'' while the thyristor reaches saturation, and then switches to a low impedance state. The saturable transformer functions as a switching transformer with high impedance while a load coupling capacitor charges, and then switches to a low impedance state to dump the charge of the storage capacitor into the load through the coupling capacitor. The transformer is comprised of a multilayer core having two secondary windings tightly wound and connected in parallel to add their output voltage and reduce output inductance, and a number of single turn windings connected in parallel at nodes for the primary winding, each single turn winding linking a different one of the layers of the multilayer core. The load may be comprised of a resistive beampipe for a linear particle accelerator and capacitance of a pulse forming network. To hold off discharge of the capacitance until it is fully charged, a saturable core is provided around the resistive beampipe to isolate the beampipe from the capacitance until it is fully charged. 5 figs.

First DOE/EPRI Green Pricing Workshop First DOE/EPRI Green Pricing Workshop April 11-12, 1996 Golden, Colorado Prepared by Blair G. Swezey, National Renewable Energy Laboratory Terry M. Peterson, Electric Power Research Institute I. Overview Green pricing is an evolving utility service that responds to utility customers' preferences for electricity derived from renewable energy sources such as solar, wind, or biomass. Under green pricing, utilities offer customers a voluntary program or service to support electricity generated from renewable energy systems. Customers are asked to pay a rate premium, which is meant to cover the costs that the utility incurs above those paid today for electricity from conventional fuels. Utilities are considering green pricing as a way to build customer loyalty, deploy popular renewable technologies, expand business lines and expertise, and improve understanding of customer response to unbundled pricing and services.

Green Power Network: Government Purchasing  

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

Government Purchasing Government Purchasing Community Choice Aggregation Disclosure Policies Green Power Policies Net Metering Policies Government Purchasing A number of governments, at both the federal, state, and local level, have established targets or goals for the amount of green power that their facilities should use. At the federal level, the Energy Policy Act of 2005 requires that federal government purchase 3% renewable energy in fiscal years 2007-2009, 5% in fiscal years 2010-2012, and 7.5% in fiscal year 2013 and thereafter. In January 2007, Executive Order 13423 established that at least half of the mandated renewable energy come from generation built after January 1, 1999. State governments, including Connecticut, Illinois, Indiana, Maine, Maryland, Massachusetts, New York, Pennsylvania, and Wisconsin, have committed to purchasing green power.

Isolated and soft-switched power converter  

DOE Patents (OSTI)

An isolated and soft-switched power converter is used for DC/DC and DC/DC/AC power conversion. The power converter includes two resonant tank circuits coupled back-to-back through an isolation transformer. Each resonant tank circuit includes a pair of resonant capacitors connected in series as a resonant leg, a pair of tank capacitors connected in series as a tank leg, and a pair of switching devices with anti-parallel clamping diodes coupled in series as resonant switches and clamping devices for the resonant leg. The power converter is well suited for DC/DC and DC/DC/AC power conversion applications in which high-voltage isolation, DC to DC voltage boost, bidirectional power flow, and a minimal number of conventional switching components are important design objectives. For example, the power converter is especially well suited to electric vehicle applications and load-side electric generation and storage systems, and other applications in which these objectives are important. The power converter may be used for many different applications, including electric vehicles, hybrid combustion/electric vehicles, fuel-cell powered vehicles with low-voltage starting, remote power sources utilizing low-voltage DC power sources, such as photovoltaics and others, electric power backup systems, and load-side electric storage and generation systems.

M.Nagrial, Switched reluctance generator for wind power applications  

E-Print Network (OSTI)

AbstractGreen house effect has becomes a serious concern in many countries due to the increase consumption of the fossil fuel. There have been many studies to find an alternative power source. Wind energy found to be one of the most useful solutions to help in overcoming the air pollution and global. There is no agreed solution to conversion of wind energy to electrical energy. In this paper, the advantages of using a Switched Reluctance Generator (SRG) for wind energy applications. The theoretical study of the self excitation of a SRG and the determination of the variable parameters in a SRG design are discussed. The design parameters for the maximum power output of the SRG are computed using Matlab simulation. The designs of the circuit to control the variable parameters in a SRG to provide the maximum power output are also discussed.

The role of public policy in emerging green power markets: An analysis of marketer preferences  

SciTech Connect

Green power marketing has been heralded by some as a means to create a private market for renewable energy that is driven by customer demand for green products. This report challenges the premise--sometimes proffered in debates over green markets--that profitable, sizable, credible markets for green products will evolve naturally without supportive public policies. Relying primarily on surveys and interviews of US green power marketers, the article examines the role of specific regulatory and legislative policies in enabling the green market, and searches for those policies that are believed by marketers to be the most conducive or detrimental to the expansion of the green market. The authors find that marketers: (1) believe that profitable green power markets will only develop if a solid foundation of supportive policies exists; (2) believe that establishing overall price competition and encouraging customer switching are the top priorities; (3) are somewhat leery of government-sponsored or mandated public information programs; and (4) oppose three specific renewable energy policies that are frequently advocated by renewable energy enthusiasts, but that may have negative impacts on the green marketers' profitability. The stated preferences of green marketers shed light on ways to foster renewables by means of the green market. Because the interests of marketers do not coincide perfectly with those of society, however, the study also recognizes other normative perspectives and highlights policy tensions at the heart of current debates related to green markets. By examining these conflicts, they identify three key policy questions that should direct future research: (1) to what extent should price competition and customer switching be encouraged at the expense of cost shifting; (2) what requirements should be imposed to ensure credibility in green products and marketing; and (3) how should the green power market and broader renewable energy policies interact?

Voluntary Green Power Market Forecast through 2015  

SciTech Connect

Various factors influence the development of the voluntary 'green' power market--the market in which consumers purchase or produce power from non-polluting, renewable energy sources. These factors include climate policies, renewable portfolio standards (RPS), renewable energy prices, consumers' interest in purchasing green power, and utilities' interest in promoting existing programs and in offering new green options. This report presents estimates of voluntary market demand for green power through 2015 that were made using historical data and three scenarios: low-growth, high-growth, and negative-policy impacts. The resulting forecast projects the total voluntary demand for renewable energy in 2015 to range from 63 million MWh annually in the low case scenario to 157 million MWh annually in the high case scenario, representing an approximately 2.5-fold difference. The negative-policy impacts scenario reflects a market size of 24 million MWh. Several key uncertainties affect the results of this forecast, including uncertainties related to growth assumptions, the impacts that policy may have on the market, the price and competitiveness of renewable generation, and the level of interest that utilities have in offering and promoting green power products.

Transistorized power switch and base drive circuit therefore  

DOE Green Energy (OSTI)

A high power switching circuit is disclosed which utilizes a four-terminal Darlington transistor block to improve switching speed, particularly in rapid turn-off. Two independent reverse drive currents are utilized during turn-off in order to expel the minority carriers of the Darlington pair at their own charge sweep-out rate. The reverse drive current may be provided by a current transformer, the secondary of which is tapped to the base terminal of the power stage of the Darlington block. In one application, the switching circuit is used in each power switching element in a chopper-inverter drive of an electric vehicle propulsion system.

High Power Microwave Switch Employing Electron Beam Triggering  

Science Conference Proceedings (OSTI)

A new type of switch for modulation of the Q-factor of a multi-mode storage resonator in a high-power active microwave pulse compressor is described. The operating principle of the switch is based on a sharp increase in the TE{sub 02{yields}}TE{sub 01} coupling coefficient, when an electron beam is injected into the switch cavity. The switch was tested at low power level in a compressor operated at X-band. A power gain of 19-20 in the compressed pulse with pulse duration of 40-50 ns was achieved. The proposed switch shows good prospects for use in high-power active pulse compressors.

Green Power: Make Your Plug-in Vehicle Even Greener Green Power: Make Your Plug-in Vehicle Even Greener Your plug-in hybrid or all-electric vehicle can help reduce oil dependence. It can also reduce emissions of greenhouse gases (GHGs) that lead to climate change if the electricity you use is produced by renewable energy. Even if most of the electricity in your area is generated by coal or other fossil fuels, you may be able to purchase green power for your vehicle. What Is Green Power? Green Power is electricity generated wholly or in part from renewable energy sources, such as wind and solar power, geothermal, hydropower, and various forms of biomass. The actual electricity delivered to your outlet may not be green, but your purchase of green power ensures that the power company generates that amount of power from renewable energy or purchases it from another provider

DC switching regulated power supply for driving an inductive load  

DOE Patents (OSTI)

A power supply for driving an inductive load current from a dc power supply hrough a regulator circuit including a bridge arrangement of diodes and switching transistors controlled by a servo controller which regulates switching in response to the load current to maintain a selected load current. First and second opposite legs of the bridge are formed by first and second parallel-connected transistor arrays, respectively, while the third and fourth legs of the bridge are formed by appropriately connected first and second parallel connected diode arrays, respectively. The regulator may be operated in three "stages" or modes: (1) For current runup in the load, both first and second transistor switch arrays are turned "on" and current is supplied to the load through both transistor arrays. (2) When load current reaches the desired level, the first switch is turned "off", and load current "flywheels" through the second switch array and the fourth leg diode array connecting the second switch array in series with the load. Current is maintained by alternating between modes 1 and 2 at a suitable duty cycle and switching rate set by the controller. (3) Rapid current rundown is accomplished by turning both switch arrays "off", allowing load current to be dumped back into the source through the third and fourth diode arrays connecting the source in series opposition with the load to recover energy from the inductive load. The three operating states are controlled automatically by the controller.

Selling green power in California: Product, industry, and market trends  

SciTech Connect

As one of the first US stages to open its doors to retail electric competition, California offers an important opportunity to assess the effectiveness of green power marketing as a mechanism for supporting renewable energy. This report is an interim assessment of key green power product, industry, and market trends in California. The report identifies and analyzes: the potential size of the green power market in California; the companies participating in the green power market; the green power products being offered and their prices; the impact of the green market on renewable generators and the environment; and the influence of several public policies and non-governmental programs on the market for green power. Data used in this paper have been collected, in large part, from surveys and interviews with green power marketers that took place between December 1997 and April 1998. There remain legitimate concerns over the viability of green power marketing to support significant quantities of renewable energy and provide large environmental gains, and it is far too early to assess the overall strength of customer demand for renewable energy. A critical finding of this report is that, because of the high cost of acquiring and servicing residential customers and the low utility default service price, green power marketing affords new energy service providers one of the only viable entrees to California`s residential marketplace.

Community Choice Aggregation (CCA) Community Choice Aggregation (CCA) Community choice aggregation (CCA) is a state policy that enables local governments to aggregate electricity demand within their jurisdictions in order to procure alternative energy supplies while maintaining the existing electricity provider for transmission and distribution services. Many states passed CCA laws as part of electric restructuring legislation in the late 1990s and early 2000s. States that have passed CCA laws include California (2002), Illinois (2009), Massachusetts (1997), New Jersey (2003), Ohio (1999), and Rhode Island (1997). There are many reasons that a community may choose to develop a CCA, including the option to purchase more green power, reduce electricity cost, and provide power from more local sources.

ABSTRACT The advent of electric utility deregulation has created a market for green power; electricity generated in whole or in part from renewable resources. Green power satisfies both the environmental yearnings of its purchasers and the need of its sellers to differentiate their product offerings. While green power has captured a significant percentage of those residential and small commercial customers that have left their host utility, the percentage of all eligible customers in competitive markets that have chosen green power is still very small. This paper examines the development of competitive markets for green power in four states that have deregulated their electric utilities - California, Pennsylvania, New Jersey, and Massachusetts.

Zero-switching-loss inverters for high-power applications  

SciTech Connect

The development of zero-switching-loss inverters has attracted much interest for industrial applications. The resonant dc link inverter (RDCLI) provides a simple and robust approach for realizing switching frequencies >20 kHz in multi-kilowatt systems but impresses substantial voltage stress (-- 2.5 supply voltage) across the devices. Two alternate topologies for realizing zero switching losses in high-power converters are proposed. The actively clamped resonant dc-link inverter (ACRLI) uses the concept of a lossless active clamp to restrict voltage stresses to only 1.3-1.5 supply voltage (V/sub s/) while maintaining a mode of operation similar to the RDCLI. For applications demanding substantially superior spectral performance, the resonant pole inverter (RPI), also called the quasi-resonant current mode inverter (QRCMI), is proposed as a viable topology. Detailed analysis, simulation, and experimental results are presented to verify operation principles of both power converters.

Active high-power RF switch and pulse compression system  

DOE Patents (OSTI)

A high-power RF switching device employs a semiconductor wafer positioned in the third port of a three-port RF device. A controllable source of directed energy, such as a suitable laser or electron beam, is aimed at the semiconductor material. When the source is turned on, the energy incident on the wafer induces an electron-hole plasma layer on the wafer, changing the wafer's dielectric constant, turning the third port into a termination for incident RF signals, and. causing all incident RF signals to be reflected from the surface of the wafer. The propagation constant of RF signals through port 3, therefore, can be changed by controlling the beam. By making the RF coupling to the third port as small as necessary, one can reduce the peak electric field on the unexcited silicon surface for any level of input power from port 1, thereby reducing risk of damaging the wafer by RF with high peak power. The switch is useful to the construction of an improved pulse compression system to boost the peak power of microwave tubes driving linear accelerators. In this application, the high-power RF switch is placed at the coupling iris between the charging waveguide and the resonant storage line of a pulse compression system. This optically controlled high power RF pulse compression system can handle hundreds of Megawatts of power at X-band.

A high average power electro-optic switch using KTP  

SciTech Connect

High damage threshold, high thermal conductivity, and small thermo-optic coefficients make KTiOPO{sub 4} (KTP) an attractive material for use in a high average power Q-switch. However, electro-chromic damage and refractive index homogeneity have prevented the utilization of KTP in such a device in the past. This work shows that electro-chromic damage is effectively suppressed using capacitive coupling, and a KTP crystal can be Q-switched for 1.5 {times} 10{sup 9} shots without any detectable electro-chromic damage. In addition, KTP with the high uniformity and large aperture size needed for a KTP electro-optic Q-switch can be obtained from flux crystals grown at constant temperature. A thermally compensated, dual crystal KTP Q-switch, which successfully produced 50 mJ pulses with a pulse width of 8 ns (FWHM), has been constructed. In addition, in off-line testing the Q-switch showed less than 7% depolarization at an average power loading of 3.2 kW/cm{sup 2}.

Ferroelectric opening switches for large-scale pulsed power drivers.  

DOE Green Energy (OSTI)

Fast electrical energy storage or Voltage-Driven Technology (VDT) has dominated fast, high-voltage pulsed power systems for the past six decades. Fast magnetic energy storage or Current-Driven Technology (CDT) is characterized by 10,000 X higher energy density than VDT and has a great number of other substantial advantages, but it has all but been neglected for all of these decades. The uniform explanation for neglect of CDT technology is invariably that the industry has never been able to make an effective opening switch, which is essential for the use of CDT. Most approaches to opening switches have involved plasma of one sort or another. On a large scale, gaseous plasmas have been used as a conductor to bridge the switch electrodes that provides an opening function when the current wave front propagates through to the output end of the plasma and fully magnetizes the plasma - this is called a Plasma Opening Switch (POS). Opening can be triggered in a POS using a magnetic field to push the plasma out of the A-K gap - this is called a Magnetically Controlled Plasma Opening Switch (MCPOS). On a small scale, depletion of electron plasmas in semiconductor devices is used to affect opening switch behavior, but these devices are relatively low voltage and low current compared to the hundreds of kilo-volts and tens of kilo-amperes of interest to pulsed power. This work is an investigation into an entirely new approach to opening switch technology that utilizes new materials in new ways. The new materials are Ferroelectrics and using them as an opening switch is a stark contrast to their traditional applications in optics and transducer applications. Emphasis is on use of high performance ferroelectrics with the objective of developing an opening switch that would be suitable for large scale pulsed power applications. Over the course of exploring this new ground, we have discovered new behaviors and properties of these materials that were here to fore unknown. Some of these unexpected discoveries have lead to new research directions to address challenges.

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

Community Renewable Energy Development Community Renewable Energy Development Community renewable energy development can take many forms, including offering a community renewable energy program, developing a community green power challenge, or developing local renewable projects. Some communities are installing renewable energy on local government facilities. For example, the City of Boulder installed a biomass burner to heat its county jail. Other local governments are installing solar on school buildings or community centers. For more information, see examples of state and local governments that have installed on-site renewable energy systems. Community Renewable Energy Programs Community renewable energy programs allow customers to purchase a share of a renewable system developed in the local community and receive the benefits of the energy that is produced by their share. For example, the Holy Cross Energy solar project in El Jebel, Colorado is an 80 kilowatt (kW) photovoltaic system supported by 18 community participants that purchase shares at an upfront cost of $3.15 per watt ($3,150 per kW) and then receive a credit on their bill each month at a rate of $0.11 per kilowatt-hour.

The 4X6 network: A new power switching scheme  

SciTech Connect

This paper describes a new power delivery switching concept which is patented in the USA and Canada. The basic network has 4 nodes and 6 branches and so is called a 4 x 6 switching network. For larger substations, it has substantial advantages over the traditional double breaker, breaker and one-half, and breaker and one-third: up to 40% fewer breakers; higher reliability; and reduced station area in some cases. For some applications, it can provide lower short-circuit levels and bus ampacity ratings thorugh the judicious use of normally open circuit breakers. The concept is applicable to all types of conventional switchgear including SF6.

E-beam high voltage switching power supply  

DOE Patents (OSTI)

A high power, solid state power supply is described for producing a controllable, constant high voltage output under varying and arcing loads suitable for powering an electron beam gun or other ion source. The present power supply is most useful for outputs in a range of about 100-400 kW or more. The power supply is comprised of a plurality of discrete switching type dc-dc converter modules, each comprising a voltage regulator, an inductor, an inverter for producing a high frequency square wave current of alternating polarity, an improved inverter voltage clamping circuit, a step up transformer, and an output rectifier for producing a dc voltage at the output of each module. The inputs to the converter modules are fed from a common dc rectifier/filter and are linked together in parallel through decoupling networks to suppress high frequency input interactions. The outputs of the converter modules are linked together in series and connected to the input of the transmission line to the load through a decoupling and line matching network. The dc-dc converter modules are phase activated such that for n modules, each module is activated equally 360.degree./n out of phase with respect to a successive module. The phased activation of the converter modules, combined with the square current waveforms out of the step up transformers, allows the power supply to operate with greatly reduced output capacitance values which minimizes the stored energy available for discharge into an electron beam gun or the like during arcing. The present power supply also provides dynamic response to varying loads by controlling the voltage regulator duty cycle using simulated voltage feedback signals and voltage feedback loops. Circuitry is also provided for sensing incipient arc currents reflected at the output of the power supply and for simultaneously decoupling the power supply circuitry from the arcing load.

A high-power switch-mode dc power supply for dynamic loads  

SciTech Connect

High-voltage dc power supplies are often required to operate with highly dynamic loads, such as arcs. A switch-mode dc power supply can offer significant advantages over conventional thyristor-based dc power supplies under such conditions. It can quickly turn off the supply to extinguish the arc, and it can quickly recover after the arc. It has a relatively small output filter capacitance, which results in small stored energy available to the arc. A 400-kW, 50-kV switch-mode dc power supply for an electron-beam gun that exploits these advantages was designed and tested. It uses four 100-kW, current-source-type dc-dc converters with inputs in parallel and outputs in series. The dc-dc converters operate at 20 kHz in the voltage regulator part and 10 kHz in the inverter, transformer, and output rectifier part of the circuit. Insulated gate bipolar transistors (IGBTs) are used as the power switches. Special techniques are used to protect the power supply and load against arcs and hard shorts. The power supply has an efficiency of 93%, an output voltage ripple of 1%, and fast dynamic response. In addition, it is nearly one-third the size of conventional power supplies.

Efficient Switches for Solar Power Conversion: Four Quadrant GaN Switch Enabled Three Phase Grid-Tied Microinverters  

Science Conference Proceedings (OSTI)

Solar ADEPT Project: Transphorm is developing power switches for new types of inverters that improve the efficiency and reliability of converting energy from solar panels into useable electricity for the grid. Transistors act as fast switches and control the electrical energy that flows in an electrical circuit. Turning a transistor off opens the circuit and stops the flow of electrical current; turning it on closes the circuit and allows electrical current to flow. In this way a transistor can be used to convert DC from a solar panel into AC for use in a home. Transphorms transistors will enable a single semiconductor device to switch electrical currents at high-voltage in both directionsmaking the inverter more compact and reliable. Transphorm is using Gallium Nitride (GaN) as a semiconductor material in its transistors instead of silicon, which is used in most conventional transistors, because GaN transistors have lower losses at higher voltages and switching frequencies.

Stabilizing control of parallel AC-DC power transmission systems by approximate switching curve  

SciTech Connect

A method to improve the transient stability of bulk power transmission system is presented. The method stabilizes the control of parallel ac-dc transmission systems using an approximate switching curve. The optimal switching curve is approximated by a power series and the resulting switching curve is determined independent of type and duration of faults that occur to the system. In addition, coefficients of the switching curve can be calculated on a off-line basis which allows use of simple on-line algebraic calculations in emergency conditions.

A low-power circuit for piezoelectric vibration control by synchronized switching on voltage sources  

E-Print Network (OSTI)

In the paper, a vibration damping system powered by harvested energy with implementation of the so-called SSDV (synchronized switch damping on voltage source) technique is designed and investigated. In the semi-passive approach, the piezoelectric element is intermittently switched from open-circuit to specific impedance synchronously with the structural vibration. Due to this switching procedure, a phase difference appears between the strain induced by vibration and the resulting voltage, thus creating energy dissipation. By supplying the energy collected from the piezoelectric materials to the switching circuit, a new low-power device using the SSDV technique is proposed. Compared with the original self-powered SSDI (synchronized switch damping on inductor), such a device can significantly improve its performance of vibration control. Its effectiveness in the single-mode resonant damping of a composite beam is validated by the experimental results.

Combined flux compression and plasma opening switch on the Saturn pulsed power generator  

E-Print Network (OSTI)

A wire-array flux-compression cartridge installed on Sandia's Saturn pulsed power generator doubled the current into a 3-nH load to 6 MA and halved its rise time to 100 ns. The current into the load, however, was unexpectedly delayed by almost 1 microsecond. Estimates of a plasma flow switch acting as a long-conduction-time opening switch are consistent with key features of the power compression. The results suggest that microsecond-conduction-time plasma flow switches can be combined with flux compression both to amplify currents and to sharpen pulse rise times in pulsed power drivers.

New single-switch three-phase high power factor rectifiers using multi-resonant zero current switching  

E-Print Network (OSTI)

Abstract A new family of single-switch three-phase highpower-factor rectifiers, which have continuous input and output currents, is introduced. By using a multiresonant scheme, the transistor operates with zero-current switching (ZCS), and the diodes operate with zero-voltage switching (ZVS). These multiresonant rectifiers with a single transistor are capable of drawing a higher quality input-current waveform at nearly unity power factor and lower stresses than quasi-resonant rectifiers. Buck-type converters are used for the power stage, and, hence, the output voltage is lower than the input voltage. Moreover, these rectifiers have a wide load range and low stresses on semiconductor devices. From the analysis, normalized characteristics of the rectifier are derived. The design and breadboard implementation of the rectifier delivering 147 V? at 6 kW from a 30 240-V???@vvA input is described. The total harmonic distortion (THD) of the line current is less than 5%, and the system efficiency is about 94% at the full load.

Implications of Carbon Regulation for Green Power Markets  

Science Conference Proceedings (OSTI)

This paper examines the potential effects that emerging mandatory carbon markets have for voluntary markets for renewable energy, or green power markets. In an era of carbon regulation, green power markets will continue to play an important role because many consumers may be interested in supporting renewable energy development beyond what is supported through mandates or other types of policy support. The paper examines the extent to which GHG benefits motivate consumers to make voluntary renewable energy purchases and summarizes key issues emerging as a result of these overlapping markets, such as the implications of carbon regulation for renewable energy marketing claims, the demand for and price of renewable energy certificates (RECs), and the use of RECs in multiple markets (disaggregation of attributes). It describes carbon regulation programs under development in the Northeast and California, and how these might affect renewable energy markets in these regions, as well as the potential interaction between voluntary renewable energy markets and voluntary carbon markets, such as the Chicago Climate Exchange (CCX). It also briefly summarizes the experience in the European Union, where carbon is already regulated. Finally, the paper presents policy options for policymakers and regulators to consider in designing carbon policies to enable carbon markets and voluntary renewable energy markets to work together.

Design and testing of high power, repetitively pulsed solid-state closing switches  

DOE Green Energy (OSTI)

Repetitively pulsed closing switches are often required in high-power physics experiments. Traditionally, ignitrons have been used for these applications. There are reasons why ignitrons have undesirable features, such as the high trigger current which causes electromagnetic interference, the arc instability and environmental concern with the mercury used in the switches. With the development of ever increasing power rating of solid-state switches, in particular thyristors, the designer has the tools to replace ignitrons with solid-state devices. Using as an example a recently designed and tested 10 kV, 80 kA high-power switch, the design philosophy for repetitively pulsed switches is developed. The parameters which impose the greatest challenge on the device, such as di/dt, temperature rise and reverse blocking voltage are investigated with respect to their capability when operating in the pulsed mode. Starting with the available device data sheet information and published results of the dependency of the number of life cycles as a function of the device temperature, it is shown how the overload capability of a device for short term pulsed applications can be exploited. The detailed design of a 2 Hz, 10{sup 8} cycle, 12.5 kV, 80 kA, 3 ms switch, with a short circuit capability of 250 kA, is presented. The paper concludes with a short summary about device limits in voltage, current amplitude and pulse length ratings for repetitively pulsed switches using available thyristors.

Fuel cell power supply with oxidant and fuel gas switching  

DOE Patents (OSTI)

This invention relates to a fuel cell vehicular power plant. Fuel for the fuel stack is supplied by a hydrocarbon (methanol) catalytic cracking reactor and CO shift reactor. A water electrolysis subsystem is associated with the stack. During low power operation part of the fuel cell power is used to electrolyze water with hydrogen and oxygen electrolysis products being stored in pressure vessels. During peak power intervals, viz, during acceleration or start-up, pure oxygen and pure hydrogen from the pressure vessel are supplied as the reaction gases to the cathodes and anodes in place of air and methanol reformate. This allows the fuel cell stack to be sized for normal low power/air operation but with a peak power capacity several times greater than that for normal operation.

The authors present the design and a proof of principle experimental results of an optically controlled high power rf pulse compression system. The design should, in principle, handle few hundreds of Megawatts of power at X-band. The system is based on the switched resonant delay line theory. It employs resonant delay lines as a means of storing rf energy. The coupling to the lines is optimized for maximum energy storage during the charging phase. To discharge the lines, a high power microwave switch increases the coupling to the lines just before the start of the output pulse. The high power microwave switch, required for this system, is realized using optical excitation of an electron-hole plasma layer on the surface of a pure silicon wafer. The switch is designed to operate in the TE{sub 01} mode in a circular waveguide to avoid the edge effects present at the interface between the silicon wafer and the supporting waveguide; thus, enhancing its power handling capability.

Green Power Marketing in the United States: A Status Report (Eighth Edition)  

SciTech Connect

Voluntary consumer decisions to purchase electricity supplied by renewable energy sources represent a powerful market support mechanism for renewable energy development. Beginning in the early 1990s, a small number of U.S. utilities began offering "green power" options to their customers. Since then, these products have become more prevalent, both from utilities and in states that have introduced competition into their retail electricity markets. Today, more than 50% of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. This report provides an overview of green power marketing activity in the United States. The first section provides an overview of green power markets, consumer response, and recent industry trends. The second section provides brief descriptions of utility green pricing programs. The third section describes companies that actively market green power in competitive markets and those that market renewable energy certificates nationally or regionally. The final section provides information on a select number of large, nonresidential green power purchasers, including businesses, universities, and government agencies.

FERROELECTRIC SWITCH FOR A HIGH-POWER Ka-BAND ACTIVE PULSE COMPRESSOR  

Science Conference Proceedings (OSTI)

Results are presented for design of a high-power microwave switch for operation at 34.3 GHz, intended for use in an active RF pulse compressor. The active element in the switch is a ring of ferroelectric material, whose dielectric constant can be rapidly changed by application of a high-voltage pulse. As envisioned, two of these switches would be built into a pair of delay lines, as in SLED-II at SLAC, so as to allow 30-MW ?s-length Ka-band pulses to be compressed in time by a factor-of-9 and multiplied in amplitude to generate 200 MW peak power pulses. Such high-power pulses could be used for testing and evaluation of high-gradient mm-wave accelerator structures, for example. Evaluation of the switch design was carried out with an X-band (11.43 GHz) prototype, built to incorporate all the features required for the Ka-band version.

Green Power Marketing in the United States: A Status Report (2008 Data)  

Science Conference Proceedings (OSTI)

Voluntary consumer decisions to buy electricity supplied from renewable energy sources represent a powerful market support mechanism for renewable energy development. In the early 1990s, a small number of U.S. utilities began offering 'green power' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from renewable energy marketers operating in states that have introduced competition into their retail electricity markets or offering renewable energy certificates (RECs) online. Today, more than half of all U.S. electricity customers have an option to purchase some type of green power product directly from a retail electricity provider, while all consumers have the option to purchase RECs. This report documents green power marketing activities and trends in the United States including utility green pricing programs offered in regulated electricity markets; green power marketing activity in competitive electricity markets, as well as green power sold to voluntary purchasers in the form of RECs; and renewable energy sold as greenhouse gas offsets in the United States. These sections are followed by a discussion of key market trends and issues. The final section offers conclusions and observations.

Customer Customer Choice and Green Power Marketing: A Critical Review and Analysis of Experience to Date Ryan Wiser, Lawrence Berkeley National Laboratory Mark Bolinger, Lawrence Berkeley National Laboratory Edward Holt, Ed Holt & Associates, Inc. ABSTRACT This article explores whether and to what extent individuals are willing to voluntarily pay a premium for products that provide public environmental benefits. In particular, we critically review and analyze the status and impacts of U.S. green power marketing to date. Green power marketing-the business of selling electricity products distinguished by their environmental attributes-seeks to develop a private market for renewable energy driven by consumer demand for green products. Debate has centered on the ability of such a market to provide a significant level of support for renewable energy sources. This paper examines

From Packet to Power Switching: Digital Direct Load Scheduling  

E-Print Network (OSTI)

At present, the power grid has tight control over its dispatchable generation capacity but a very coarse control on the demand. Energy consumers are shielded from making price-aware decisions, which degrades the efficiency of the market. This state of affairs tends to favor fossil fuel generation over renewable sources. Because of the technological difficulties of storing electric energy, the quest for mechanisms that would make the demand for electricity controllable on a day-to-day basis is gaining prominence. The goal of this paper is to provide one such mechanisms, which we call Digital Direct Load Scheduling (DDLS). DDLS is a direct load control mechanism in which we unbundle individual requests for energy and digitize them so that they can be automatically scheduled in a cellular architecture. Specifically, rather than storing energy or interrupting the job of appliances, we choose to hold requests for energy in queues and optimize the service time of individual appliances belonging to a broad class whi...

Certificate-Based Approach to Marketing Green Power and Constructing New Wind Energy Facilities: Preprint  

DOE Green Energy (OSTI)

The availability of wind energy certificates in Pennsylvania's retail electricity market has made a critical difference in the economic feasibility of developing 140 MW of new wind energy projects in the region. Certificates offer important benefits to both green power suppliers and buyers by reducing transaction barriers and thus lowering the cost of renewable energy. Buyers also benefit through the increased flexibility offered by certificate products. The experience described in this paper offers important insights for selling green power certificates and achieving new wind energy development in other areas of the country.

On-site Renewable Energy Systems On-site Renewable Energy Systems For consumers or organizations wishing to install on-site renewable energy systems, there are a variety of options available, including electricity generating systems and thermal systems that can displace electricity or fossil fuel use. Solar photovoltaics convert sunlight directly into electricity. Solar hot water systems use the sun's energy to heat water. Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce electricity. Geothermal heat pumps use the constant temperature of the upper 10 feet of the Earth to heat and cool buildings. Fuel cells produce electricity from hydrogen and oxygen and can be powered by a number of sources, including renewables. Biomass power systems use biomass feedstocks such as wood waste or methane from animal waste or other sources to generate electricity. Biomass resources can also be used in direct heat and combined heat and power applications.

The Development of the Electrically Controlled High Power RF Switch and Its Application to Active RF Pulse Compression Systems  

SciTech Connect

In the past decades, there has been increasing interest in pulsed high power RF sources for building high-gradient high-energy particle accelerators. Passive RF pulse compression systems have been used in many applications to match the available RF sources to the loads requiring higher RF power but a shorter pulse. Theoretically, an active RF pulse compression system has the advantage of higher efficiency and compactness over the passive system. However, the key component for such a system an element capable of switching hundreds of megawatts of RF power in a short time compared to the compressed pulse width is still an open problem. In this dissertation, we present a switch module composed of an active window based on the bulk effects in semiconductor, a circular waveguide three-port network and a movable short plane, with the capability to adjust the S-parameters before and after switching. The RF properties of the switch module were analyzed. We give the scaling laws of the multiple-element switch systems, which allow the expansion of the system to a higher power level. We present a novel overmoded design for the circular waveguide three-port network and the associated circular-to-rectangular mode-converter. We also detail the design and synthesis process of this novel mode-converter. We demonstrate an electrically controlled ultra-fast high power X-band RF active window built with PIN diodes on high resistivity silicon. The window is capable of handling multi-megawatt RF power and can switch in 2-300ns with a 1000A current driver. A low power active pulse compression experiment was carried out with the switch module and a 375ns resonant delay line, obtaining 8 times compression gain with a compression ratio of 20.

On-site Renewable Energy Third-Party Solar Financing Third-Party Solar Financing Third-Party Ownership of Distributed Solar Power Systems Historically, the up-front cost of solar has discouraged many residential and commercial customers who may otherwise wish to generate their electricity with solar power. The provision of this initial investment through traditional financing arrangements can often lead to prohibitively high interest rates on loans for a solar system rendering the economics of the investment unfavorable. In the late 2000s, solar installers and developers began to develop the concept of providing solar electricity to a customer - or, the service of generating electricity from solar panels - without requiring that the customer own a solar electric system.

A novel maximum power point tracker for PV panels using switching frequency modulation  

E-Print Network (OSTI)

AbstractA novel technique for efficiently extracting maximum power from photovoltaic (PV) panels is presented. The power conversion stage, which is connected between a PV panel and a load or bus, is a SEPIC or Cuk converter or their derived circuits operating in discontinuous inductorcurrent or capacitorvoltage mode. Method of locating the maximum power point (MPP) is based on injecting a small-signal sinusoidal perturbation into the switching frequency and comparing the ac component and the average value of the panel terminal voltage. Apart from not requiring any sophisticated digital computation of the panel power, the proposed technique does not approximate the panel characteristics and can globally locate the MPP under wide insolation conditions. The tracking capability has been verified experimentally with a 10 W solar panel under a controlled experimental setup. Performances under the steady state and in the large-signal change of the insolation level will be given. Index TermsDCDC power conversion, maximum-powerpoint tracking, photovoltaic. I.

Mill Seat Landfill Bioreactor Renewable Green Power (NY)  

Science Conference Proceedings (OSTI)

The project was implemented at the Mill Seat landfill located in the Town of Bergen, Monroe County, New York. The landfill was previously equipped with a landfill gas collection system to collect methane gas produced by the bioreactor landfill and transport it to a central location for end use. A landfill gas to energy facility was also previously constructed at the site, which utilized generator engines, designed to be powered with landfill methane gas, to produce electricity, to be utilized on site and to be sold to the utility grid. The landfill gas generation rate at the site had exceeded the capacity of the existing generators, and the excess landfill gas was therefore being burned at a candlestick flare for destruction. The funded project consisted of the procurement and installation of two (2) additional 800 KW Caterpillar 3516 generator engines, generator sets, switchgear and ancillary equipment.

Spectrographic temperature measurement of a high power breakdown arc in a high pressure gas switch  

Science Conference Proceedings (OSTI)

A procedure for obtaining an approximate temperature value of conducting plasma generated during self-break closure of a RIMFIRE gas switch is described. The plasma is in the form of a breakdown arc which conducts approximately 12 kJ of energy in 1 {mu}s. A spectrographic analysis of the trigger-section of the 6-MV RIMFIRE laser triggered gas switch used in Sandia National Laboratory's ''Z-Machine'' has been made. It is assumed that the breakdown plasma has sufficiently approached local thermodynamic equilibrium allowing a black-body temperature model to be applied. This model allows the plasma temperature and radiated power to be approximated. The gas dielectric used in these tests was pressurized SF{sub 6}. The electrode gap is set at 4.59 cm for each test. The electrode material is stainless steel and insulator material is poly(methyl methacrylate). A spectrum range from 220 to 550 nanometers has been observed and calibrated using two spectral irradiance lamps and three spectrograph gratings. The approximate plasma temperature is reported.

Argonne TTRDC - Green Racing - Results  

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

Results and Recaps Results and Recaps Green Racing Initiative - 2011 Season The Green Racing Initiative, managed by Argonne for the U.S. Department of Energy (DOE), has become an integral part of the American Le Mans Series (ALMS). The 2011 season continued the growth and acceptance of green racing activities in the Series. In August 2011, ALMS announced that it would implement Green Racing 2.0 in future races. Renewable Fuel Use The 2011 ALMS season saw the use of non-petroleum and renewable fuels become dominant. Every Green Challenge victory in the Gran Turismo (GT) category and five out of nine victories in the Le Mans Prototype (LMP) category were won by a car using advanced fuels. Underlining the significance of this movement to advanced renewable fuels is that teams and engineers from all over the world made the decision to switch to these fuels because of their performance advantages alone. There were no incentives for switching in the form of funding or extra points. ALMS goes to great lengths to balance the performance of all the cars, so the switch to these fuels was made solely because they offered better efficiency and, in some cases, more power. The Green Challenge scoring system, developed by Argonne engineers in cooperation with the ALMS, accurately reflects renewable fuels' characteristics in terms of its greenhouse gas and oil replacement attributes without rewarding their selection of these over conventional fuels. That is what makes this switch to renewable replacements for conventional oil-based fuels all the more significant.

Latching micro optical switch  

DOE Patents (OSTI)

An optical switch reliably maintains its on or off state even when subjected to environments where the switch is bumped or otherwise moved. In addition, the optical switch maintains its on or off state indefinitely without requiring external power. External power is used only to transition the switch from one state to the other. The optical switch is configured with a fixed optical fiber and a movable optical fiber. The movable optical fiber is guided by various actuators in conjunction with a latching mechanism that configure the switch in one position that corresponds to the on state and in another position that corresponds to the off state.

Power applications of high-temperature superconductivity: Variable speed motors, current switches, and energy storage for end use  

DOE Green Energy (OSTI)

The objective of this project is to conduct joint research and development activities related to certain electric power applications of high-temperature superconductivity (HTS). The new superconductors may allow development of an energy-efficient switch to control current to variable speed motors, superconducting magnetic energy storage (SMES) systems, and other power conversion equipment. Motor types that were considered include induction, permanent magnet, and superconducting ac motors. Because it is impractical to experimentally alter certain key design elements in radial-gap motors, experiments were conducted on an axial field superconducting motor prototype using 4 NbTi magnets. Superconducting magnetic energy storage technology with 0.25--5 kWh stored energy was studied as a viable solution to short duration voltage sag problems on the customer side of the electric meter. The technical performance characteristics of the device wee assembled, along with competing technologies such as active power line conditioners with storage, battery-based uninterruptible power supplies, and supercapacitors, and the market potential for SMES was defined. Four reports were prepared summarizing the results of the project.

Low Power, Red, Green and Blue Carbon Nanotube Enabled Vertical Organic Light Emitting Transistors for Active Matrix OLED Displays  

SciTech Connect

Organic semiconductors are potential alternatives to polycrystalline silicon as the semiconductor used in the backplane of active matrix organic light emitting diode displays. Demonstrated here is a light-emitting transistor with an organic channel, operating with low power dissipation at low voltage, and high aperture ratio, in three colors: red, green and blue. The single-wall carbon nanotube network source electrode is responsible for the high level of performance demonstrated. A major benefit enabled by this architecture is the integration of the drive transistor, storage capacitor and light emitter into a single device. Performance comparable to commercialized polycrystalline-silicon TFT driven OLEDs is demonstrated.

Demand Side Management in the Smart Grid: Information Processing for the Power Switch  

Science Conference Proceedings (OSTI)

In this article we discuss the most recent developments in the area of load management, and consider possible interaction schemes of novel architectures with distributed energy resources (DER). In order to handle the challenges faced by tomorrows smart grid, which are caused by volatile load and generation profiles (from the large number of plug-in EVs and from renewable integration), the conventional grid operating principle of load-following needs to be changed into load-shaping or generation-following. Demand Side Management will be a most promising and powerful solution to the above challenges. However, many other issues such as load forecasting, pricing structure, market policy, renewable integration interface, and even the AC/DC implementation at the distribution side, need to be taken into the design in order to search for the most effective and applicable solution.

Optimal Multi-Modes Switching with the Switching Cost not necessarily Positive  

E-Print Network (OSTI)

In this paper, we study the $m$-states optimal switching problem in finite horizon, when the switching cost functions are arbitrary and can be positive or negative. This has an economic incentive in terms of central evaluation in cases where such organizations or state grants or financial assistance to power plants that promotes green energy in their production activity or what uses less polluting modes in their production. We show existence for optimal strategy via a verification theorem then we show existence and uniqueness of the value processes by using an approximation scheme. In the markovian framework we show that the value processes can be characterized in terms of deterministic continuous functions of the state of the process. Those latter functions are the unique viscosity solutions for a system of $m$ variational partial differential inequalities with inter-connected obstacles.

Testing and Implementation Progress on the Advanced Photon Source (APS) Linear Accelerator (Linac) High-Power S-band Switching System  

E-Print Network (OSTI)

An S-band linear accelerator is the source of particles and the front end of the Advanced Photon Source injector. In addition, it supports a low-energy undulator test line (LEUTL) and drives a free-electron laser (FEL). A waveguide-switching and distribution system is now under construction. The system configuration was revised to be consistent with the recent change to electron-only operation. There are now six modulator-klystron subsystems, two of which are being configured to act as hot spares for two S-band transmitters each, so that no single failure will prevent injector operation. The two subsystems are also used to support additional LEUTL capabilities and off-line testing.

Experimental Research and Performance Analysis of a Solar-Powered Air-conditioning System in a Green Building  

E-Print Network (OSTI)

Based on the green building of the Shanghai Institute of Architectural Science, a solar-powered adsorption air-conditioning system was designed. The operational performance under a typical operating mode in summer was studied, which includes temperature variations of solar collector arrays, heat storage tank and adsorption chillers as well as refrigerating output variations of the system. Experimental results show that adsorption chillers have the advantages of low driving temperature, stability and long working time with high efficiency. Under representative working conditions in summer, the average refrigerating output of solar powered air-conditioning system is 15.31kW during operation of 8 hours; moreover, the maximum attains 20kW. Correspondingly, the average system COP is 0.35, and the average solar COP is 0.15. The solar fraction in summer is concluded to be 71.73%. In addition, the variations of solar-powered air-conditioning system performance with ambient parameters (solar radiant intensity and ambient temperature) and operating parameters (temperatures and flow rates) are analyzed.

Plasma flow switch experiment on Procyon  

SciTech Connect

This report presents the results obtained from a series of plasma flow switch experiments done on the Procyon explosive pulse power generator. These experiments involved switching into a fixed inductance dummy load and also into a dynamic implosion load. The results indicated that the switch did fairly well at switching current into the load, but the results for the implosion are more ambiguous. The results are compared to calculations and the implications for future plasma flow switch work are discussed.

Plasmonic enhanced ultrafast switch.  

Science Conference Proceedings (OSTI)

Ultrafast electronic switches fabricated from defective material have been used for several decades in order to produce picosecond electrical transients and TeraHertz radiation. Due to the ultrashort recombination time in the photoconductor materials used, these switches are inefficient and are ultimately limited by the amount of optical power that can be applied to the switch before self-destruction. The goal of this work is to create ultrafast (sub-picosecond response) photoconductive switches on GaAs that are enhanced through plasmonic coupling structures. Here, the plasmonic coupler primarily plays the role of being a radiation condenser which will cause carriers to be generated adjacent to metallic electrodes where they can more efficiently be collected.

Energy losses in switches  

DOE Green Energy (OSTI)

The authors experiments show energy losses between 2 and 10 times that of the resistive time predictions. The experiments used hydrogen, helium, air, nitrogen, SF{sub 6} polyethylene, and water for the switching dielectric. Previously underestimated switch losses have caused over predicting the accelerator outputs. Accurate estimation of these losses is now necessary for new high-efficiency pulsed power devices where the switching losses constitute the major portion of the total energy loss. They found that the switch energy losses scale as (V{sub peak}I{sub peak}){sup 1.1846}. When using this scaling, the energy losses in any of the tested dielectrics are almost the same. This relationship is valid for several orders of magnitude and suggested a theoretical basis for these results. Currents up to .65 MA, with voltages to 3 MV were applied to various gaps during these experiments. The authors data and the developed theory indicates that the switch power loss continues for a much longer time than the resistive time, with peak power loss generally occurring at peak current in a ranging discharge instead of the early current time. All of the experiments were circuit code modeled after developing a new switch loss version based on the theory. The circuit code predicts switch energy loss and peak currents as a function of time. During analysis of the data they noticed slight constant offsets between the theory and data that depended on the dielectric. They modified the plasma conductivity for each tested dielectric to lessen this offset.

The Treatment of Renewable Energy Certificates, EmissionsAllowances, and Green Power Programs in State Renewables PortfolioStandards  

SciTech Connect

Twenty-one states and the District of Columbia have adopted mandatory renewables portfolio standards (RPS) over the last ten years. Renewable energy attributes-such as the energy source, conversion technology, plant location and vintage, and emissions-are usually required to verify compliance with these policies, sometimes through attributes bundled with electricity, and sometimes with the attributes unbundled from electricity and traded separately as renewable energy certificates (RECs). This report summarizes the treatment of renewable energy attributes in state RPS rules. Its purpose is to provide a source of information for states considering RPS policies, and also to draw attention to certain policy issues that arise when renewable attributes and RECs are used for RPS compliance. Three specific issues are addressed: (1) the degree to which unbundled RECs are allowed under existing state RPS programs and the status of systems to track RECs and renewable energy attributes; (2) definitions of the renewable energy attributes that must be included in order to meet state RPS obligations, including the treatment of available emissions allowances; and (3) state policies on whether renewable energy or RECs sold through voluntary green power transactions may count towards RPS obligations.

Stable nonlinear Mach-Zehnder fiber switch  

DOE Patents (OSTI)

An all-optical fiber switch is implemented within a short Mach-Zehnder interferometer configuration. The Mach-Zehnder switch is constructed to have a high temperature stability so as to minimize temperature gradients and other thermal effects which result in undesirable instability at the output of the switch. The Mach-Zehnder switch of the preferred embodiment is advantageously less than 2 cm in length between couplers to be sufficiently short to be thermally stable, and full switching is accomplished by heavily doping one or both of the arms between the couplers so as to provide a highly nonlinear region within one or both of the arms. A pump input source is used to affect the propagation characteristics of one of the arms to control the output coupling ratio of the switch. Because of the high nonlinearity of the pump input arm, low pump powers can be used, thereby alleviating difficulties and high cost associated with high pump input powers.

THYRATRON SWITCH  

DOE Patents (OSTI)

An arrangement for utilizing a thyratron as a noise free switch is described. It has been discovered that the voltage between plate and cathode of a thyratron will oscillate, producing voltage spikes, if the tube carries only a fraction of its maximum rated current. These voltage spikes can produce detrimental effects where the thyratron is used in critical timing circuits. To alleviate this problem the disclosed circuit provides a charged capacitor and a resistor in parallel with the tube and of such value that the maximum current will flow from the capacitor through the thyratron when it is triggered. During this time the signal current is conducted through the tube, before the thyratron voltage starts to oscillate, and the signal current output is free of noise spikes.

This paper reports on a two-stage dye amplifier design that has been developed to amplify tunable, blue=green, subpicosecond dye laser pulses which are generated from a hybrid synchronously mode-locked dye oscillator directly (800 fs) or shorter to 200 fs by a fiber compressor stage. This system has achieved single pulse energies of 2mJ, with an amplified spontaneous emission content of less than 0.1%. Using 40 mJ of the third-harmonic output of an Nd:YAG regenerative amplifier to pump the dye amplifier system, these pulse energies represent an energy extraction efficiency of {approximately}5%. The tunability, stability, and spatial and temporal quality of throughput pulses from the system have also been characterized.

New Details of Ferroelectric Switching

New Details of Ferroelectric Switching New Details of Ferroelectric Switching All of our current information technology relies on devices that process information as binary ones and zeroes. Ferroelectric materials are of special interest to developers of the next generation of such devices because they exhibit polarized electronic states that can represent bits of information. Moreover, these materials retain their polarization states without consuming electrical power, making ferroelectrics the subject of intense study for nonvolatile memory applications in which data is stored even when the power is turned off. One problem, however, is polarization fatigue: after a number of cycles, the switchable polarization begins to taper off, rendering the device unusable. Recently, a team of researchers

Optically triggered high voltage switch network and method for switching a high voltage  

DOE Patents (OSTI)

An optically triggered solid state switch and method for switching a high voltage electrical current. A plurality of solid state switches (350) are connected in series for controlling electrical current flow between a compensation capacitor (112) and ground in a reactive power compensator (50, 50') that monitors the voltage and current flowing through each of three distribution lines (52a, 52b and 52c), which are supplying three-phase power to one or more inductive loads. An optical transmitter (100) controlled by the reactive power compensation system produces light pulses that are conveyed over optical fibers (102) to a switch driver (110') that includes a plurality of series connected optical triger circuits (288). Each of the optical trigger circuits controls a pair of the solid state switches and includes a plurality of series connected resistors (294, 326, 330, and 334) that equalize or balance the potential across the plurality of trigger circuits. The trigger circuits are connected to one of the distribution lines through a trigger capacitor (340). In each switch driver, the light signals activate a phototransistor (300) so that an electrical current flows from one of the energy reservoir capacitors through a pulse transformer (306) in the trigger circuit, producing gate signals that turn on the pair of serially connected solid state switches (350).

Photonic switching devices based on semiconductor nanostructures  

E-Print Network (OSTI)

Squeezing and guiding light into semiconductor nanostructures delivers revolutionary concepts of photonic devices, which may offer a practical pathway towards power-efficient optical networks. In this review, we consider photonic switches using semiconductor quantum dots (QDs) and photonic cavities. By intuitively introducing in a field enhancement factor, the optical nonlinearity of nano-photonic switches can be understood and this has shown their unique features to dramatically improve the power-density/speed limitation that has lain in conventional photonic switches for decades. In addition, the power consumption has been reduced due to the atom-like characterization of QDs as well as the nano-size footprint of photonic cavities. Based on this theoretical perspective, the current progress of QD/cavity switches is reviewed in terms of various optical nonlinearities which have been employed to demonstrate photonic switching at the nanoscale. Emerging functionalities enabled by cavity nonlinear effects such as the wavelength tuning and Purcell-factor tuning have been further introduced.

Vacuum interrupters and thyratrons as opening switches  

DOE Green Energy (OSTI)

The clear advantages of inductive storage for large scale energy storage applications are creating an increasing interest in the research and development of the opening switches required. Opening switches for single-shot inductive transfers have received considerable attention and are fairly well advanced. The problem addressed by this workshop of high power opening switches for high repetition rate applications is much more severe, however, and may well require a major research and development effort. Two candidates for such an opening switch, the triggered vacuum interrupter and the magnetically quenched thyratron, are discussed. By electrically retriggering the discharge in the vacuum interrupter between pulses, the dependence on mechanical motion is eliminated. This should enable repetition rate operation at 10 to 15 kHz while still maintaining the vacuum interrupter's proven interrupting performance of tens of kiloamps at tens of kilovolts. The magnetically quenched thyratron, on the other hand, uses a cross magnetic field to raise the switch impedance by decreasing the electron mobility and driving the discharge into an arc chute wall where it is quenched. Successful interruptions of 1 kA at 15 kV and 100 A at 50 kV after conduction for 10 ..mu..s have been demonstrated by previous researchers. Work at Los Alamos is directed toward understanding the basic mechanisms involved and increasing the switch ratings, particularly the conduction time.

Fast Switching Ferroelectric Materials for Accelerator Applications  

SciTech Connect

Fast switching (<10 nsec) measurement results on the recently developed BST(M) (barium strontium titanium oxide composition with magnesium-based additions) ferroelectric materials are presented. These materials can be used as the basis for new advanced technology components suitable for high-gradient accelerators. A ferroelectric ceramic has an electric field-dependent dielectric permittivity that can be altered by applying a bias voltage. Ferroelectric materials offer significant benefits for linear collider applications, in particular, for switching and control elements where a very short response time of <10 nsec is required. The measurement results presented here show that the new BST(M) ceramic exhibits a high tunability factor: a bias field of 40-50 kV/cm reduces the permittivity by a factor of 1.3-1.5. The recently developed technology of gold biasing contact deposition on large diameter (110 cm) thin wall ferroelectric rings allowed {approx}few nsec switching times in witness sample experiments. The ferroelectric rings can be used at high pulsed power (tens of megawatts) for X-band components as well as at high average power in the range of a few kilowatts for the L-band phase-shifter, under development for optimization of the ILC rf coupling. Accelerator applications include fast active X-band and Ka-band high-power ferroelectric switches, high-power X-band and L-band phase shifters, and tunable dielectric-loaded accelerating structures.

Photoconductive switch package  

SciTech Connect

A photoconductive switch is formed of a substrate that has a central portion of SiC or other photoconductive material and an outer portion of cvd-diamond or other suitable material surrounding the central portion. Conducting electrodes are formed on opposed sides of the substrate, with the electrodes extending beyond the central portion and the edges of the electrodes lying over the outer portion. Thus any high electric fields produced at the edges of the electrodes lie outside of and do not affect the central portion, which is the active switching element. Light is transmitted through the outer portion to the central portion to actuate the switch.

Cygnus PFL Switch Jitter  

Science Conference Proceedings (OSTI)

The Cygnus Dual Beam Radiographic Facility consists of two identical radiographic sources: Cygnus 1 and Cygnus 2. Each source has the following X-ray output: 1-mm diameter spot size, 4 rads at 1 m, 50-ns full-widthhalf-maximum. The diode pulse has the following electrical specifications: 2.25 MV, 60 kA, 60 ns. This Radiographic Facility is located in an underground tunnel test area at the Nevada Test Site (NTS). The sources were developed to produce high-resolution images on subcritical tests performed at NTS. Subcritical tests are single-shot, high-value events. For this application, it is desirable to maintain a high level of reproducibility in source output. The major components of the Cygnus machines are Marx generator, water-filled pulse forming line (PFL), water-filled coaxial transmission line, threecell inductive voltage adder, and rod-pinch diode. A primary source of fluctuation in Cygnus shot-to-shot performance may be jitter in breakdown of the main PFL switch, which is a self-break switch. The PFL switch breakdown time determines the peak PFL charging voltage, which ultimately affects the source X-ray spectrum and dose. Therefore, PFL switch jitter may contribute to shot-to-shot variation in these parameters, which are crucial to radiographic quality. In this paper we will present PFL switch jitter analysis for both Cygnus machines and present the correlation with dose. For this analysis, the PFL switch on each machine was maintained at a single gap setting, which has been used for the majority of shots at NTS. In addition the PFL switch performance for one larger switch gap setting will be examined.

In addition to this analysis, PFL switch performance for different switch gap settings taken recently will be examined. Lastly, implications of source jitter for radiographic diagnosis of subcritical shots will be discussed.

Royal Soc. of London. 440(1910): (1993)] to express unknown Green function in terms of three scalar functions $\\phi_i$, by using the spectral decomposition of the Christoffel tensor associated with the medium. The problem of computing Green function is, thus reduced to the resolution of three scalar wave equations satisfied by $\\phi_i$, and subsequent equations with $\\phi_i$ as source terms. To describe viscosity effects, we choose an empirical power law model which becomes well known Voigt model for quadratic frequency losses.

Multiple switch actuator  

DOE Patents (OSTI)

The present invention relates to switches and switch actuating devices to be operated for purposes of arming a bomb or other missile as it is dropped or released from an aircraft. The particular bomb or missile in which this invention is applied is one in which there is a plurality of circuits which are to be armed by the closing of switches upon dropping or releasing of the bomb. The operation of the switches to closed position is normally accomplished by means of a pull-out wire; that is, a wire which is withdrawn from the bomb or missile at the time of release of the bomb, one end of the wire being attached to the aircraft. The conditions to be met are that the arming switches must be positively and surely maintained in open position until the bomb is released and the arming action is effected. The action of the pull-out wire in achieving the arming action must be sure and positive with minimum danger of malfunctioning, jamming or binding.

Thermionic gas switch  

DOE Patents (OSTI)

A temperature responsive thermionic gas switch having folded electron emitting surfaces. An ionizable gas is located between the emitter and an interior surface of a collector, coaxial with the emitter. In response to the temperature exceeding a predetermined level, sufficient electrons are derived from the emitter to cause the gas in the gap between the emitter and collector to become ionized, whereby a very large increase in current in the gap occurs. Due to the folded emitter surface area of the switch, increasing the "on/off" current ratio and adjusting the "on" current capacity is accomplished.

Trends in Utility Green Pricing Programs (2006)  

SciTech Connect

In the early 1990s, only a handful of utilities offered their customers a choice of purchasing electricity generated from renewable energy sources. Today, more than 750 utilities--or about 25% of all utilities nationally--provide their customers a "green power" option. Through these programs, more than 70 million customers have the ability to purchase renewable energy to meet some portion or all of their electricity needs--or make contributions to support the development of renewable energy resources. Typically, customers pay a premium above standard electricity rates for this service. This report presents year-end 2006 data on utility green pricing programs, and examines trends in consumer response and program implementation over time. The data in this report, which were obtained via a questionnaire distributed to utility green pricing program managers, can be used by utilities to benchmark the success of their green power programs.

Manufacturing fuel-switching capability, 1988  

SciTech Connect

Historically, about one-third of all energy consumed in the United States has been used by manufacturers. About one-quarter of manufacturing energy is used as feedstocks and raw material inputs that are converted into nonenergy products; the remainder is used for its energy content. During 1988, the most recent year for which data are available, manufacturers consumed 15.5 quadrillion British thermal units (Btu) of energy to produce heat and power and to generate electricity. The manufacturing sector also has widespread capabilities to switch from one fuel to another for either economic or emergency reasons. There are numerous ways to define fuel switching. For the purposes of the Manufacturing Energy Consumption Survey (MECS), fuel switching is defined as the capability to substitute one energy source for another within 30 days with no significant modifications to the fuel-consuming equipment, while keeping production constant. Fuel-switching capability allows manufacturers substantial flexibility in choosing their mix of energy sources. The consumption of a given energy source can be maximized if all possible switching into that energy source takes place. The estimates in this report are based on data collected on the 1988 Manufacturing Energy Consumption Survey (MECS), Forms 846 (A through C). The EIA conducts this national sample survey of manufacturing energy consumption on a triennial basis. The MECS is the only comprehensive source of national-level data on energy-related information for the manufacturing industries. The MECS was first conducted in 1986 to collect data for 1985. This report presents information on the fuel-switching capabilities of manufacturers in 1988. This report is the second of a series based on the 1988 MECS. 8 figs., 31 tabs.

Connecting Stakeholders, Achieving Green  

E-Print Network (OSTI)

If Green is gold, why is progress so slow? The public understanding of Green is evolving. Standards are being developed, but there is still much work to be done. Achieving Green is difficult. Necessary conditions include: A plan that is realistic and sustainable; Partnership that share the efforts and benefits of Green results; and A continuous improvement process, i.e. the flexibility to evolve with a dynamic industry and market. A successful Green plan combines vision, initiative, and a willingness to invest in the right tools. To implement a successful plan, leaders have recognized that, in light of the barriers that exist, real progress cannot be made alone. Because of common interest, core stakeholders are natural and necessary allies. As the public acceptance of Green increases, core stakeholders are challenging the status quo. Consequently, stakeholders are not risking inaction, and are connecting to achieve the rewards of being Green.

Plasma opening switch  

DOE Patents (OSTI)

A command triggered plasma opening switch assembly using an amplification stage. The assembly surrounds a coaxial transmission line and has a main plasma opening switch (POS) close to the load and a trigger POS upstream from the main POS. The trigger POS establishes two different current pathways through the assembly depended on whether it has received a trigger current pulse. The initial pathway has both POS's with plasma between their anodes and cathodes to form a short across the transmission line and isolating the load. The final current pathway is formed when the trigger POS receives a trigger current pulse which energizes its fast coil to push the conductive plasma out from between its anode and cathode, allowing the main transmission line current to pass to the fast coil of the main POS, thus pushing its plasma out the way so as to establish a direct current pathway to the load.

Cygnus Diverter Switch Analysis  

Science Conference Proceedings (OSTI)

The Cygnus Dual Beam Radiographic Facility consists of two 2.25-MV, 60-kA, 50-ns x-ray sources fielded in an underground laboratory at the Nevada Test Site. The tests performed in this laboratory involve study of the dynamic properties of plutonium and are called subcritical experiments. From end-to-end, the Cygnus machines utilize the following components: Marx generator, water-filled pulse-forming line (PFL), waterfilled coaxial transmission line (WTL), 3-cell inductive voltage adder (IVA), and rod-pinch diode. The upstream WTL interface to the PFL is via a radial insulator with coaxial geometry. The downstream WTL terminates in a manifold where the center conductor splits into three lines which individually connect to each of the IVA cell inputs. There is an impedance mismatch at this juncture. It is a concern that a reflected pulse due to anomalous behavior in the IVA or diode might initiate breakdown upon arrival at the upstream PFL/WTL insulator. Therefore near the beginning of the WTL a radial diverter switch is installed to protect the insulator from over voltage and breakdown. The diverter has adjustable gap spacing, and an in-line aqueous-solution (sodium thiosulfate) resistor array for energy dissipation. There are capacitive voltage probes at both ends of the WTL and on the diverter switch. These voltage signals will be analyzed to determine diverter performance. Using this analysis the usefulness of the diverter switch will be evaluated.

Coordinated Variable Structure Switching Attacks for Smart Grid  

E-Print Network (OSTI)

The effective modeling and analysis of large-scale power system disturbances especially those stemming from intentional attack represents an open engineering and research problem. Challenges stem from the need to develop intelligent models of cyber-physical attacks that produce salient disruptions and appropriately describe meaningful cyber-physical interdependencies such that they balance precision, scale and complexity. In our research, we present a foundation for the development of a class of intelligent cyber-physical attacks termed coordinated variable structure switching attacks whereby opponents aim to destabilize the power grid through con- trolled switching sequence. Such switching is facilitated by cyber-attack and corruption of communication channels and control signals of the associated switch(es). We provide methods and theorems to construct such attack models and demonstrate their utility in the simulation of extensive system disturbances. Our proposed class of cyber-physical switching attacks for smart grid systems has the potential to disrupt large-scale power system operation within a short interval of time. Through successful cyber intrusion, an opponent can remotely apply a state- dependent coordinated switching sequence on one or more relays and circuit breakers of a power system to disrupt operation. Existence of this switching vulnerability is dependent on the local structure of the power grid. Variable structure systems theory is employed to effectively model the cyber-physical aspects of a smart grid and determine the existence of the vulnerability and construct the destabilizing switching attack sequence. We illustrate the utility of the attack approach assess its impact on the different power system test cases including the single machine infinite bus power system model and the Western Electricity Coordinating Council (WECC) 3-machine 9-bus system through MATLAB/Simulink and PSCAD simulation environment. The results demonstrate the potential of our approach for practical attack. Moreover, we build on our work in several ways. First, we extend the research to demonstrate an approach to mitigation within the variable structure system frame- work. We demonstrate via small signal analysis how through persistent switching a stable sliding mode can be used to disrupt a dynamical system that seems stable. We also design an approach to vulnerability analysis to assess the feasibility of co-ordinated variable structure switching attacks. Moreover, we study the performance of our attack construction approach when the opponent has imperfect knowledge of the local system dynamics and partial knowledge of the generator state. Based on the system with modeling errors, we study the performance of coordinated variable structure switching attacks in the presence of state estimation. Finally, we illustrate the concepts of attack model within the multiple switching framework, the cascading failure analysis is employed in the New-England 10-machine, 39-bus power system using MATLAB/Simulink and DSATools simulation environment. Our results demonstrate the potential for coordinated variable structure switching attacks to enable large-scale power system disturbances.

Battery/Charger Load Switch Approximates Ideal Diode  

E-Print Network (OSTI)

Abstract: Two circuits are described. The first uses external MOSFETs driven by the Power OK (POK) output of a Li-cell charger IC (MAX8814), to switch a load between battery and charging source without intervention from a microcontroller or system software. For charger ICs without a POK output (such as the MAX1507), the second circuit does the same switching using MOSFETs and a comparator (MAX920). A similar version of this article appeared in the July 19, 2010 issue of Electronic Design magazine. Most rechargeable battery-powered systems include a switch that connects the load either to the battery or to a source of charging power. Without it, a system with depleted battery may not operate immediately when plugged in. A switching circuit also allows the system to operate on adapter power while the battery is charging. The simplest and lowest-cost method for this battery/adapter power handoff is a diode-OR connection. The load connects to each power source (battery and adapter) through separate Schottky diodes, so power is applied by the higher voltagebattery or adapter. The drawback to this approach is the power loss (P D = I BATTERYV DIODE) and voltage drop (V DIODE = 0.350V at 0.5A, from the PMEG2010AEH data sheet) incurred when the battery services the load. Such losses may not be significant for high-voltage multicell batteries, but for 1-cell Li+ batteries or 24 cell NiMh batteries, the percentages of power loss and diode drop across the blocking diode are considerable. The circuit of Figure 1 switches loads with a voltage drop of only 45mV at 0.5A, which is a head-room improvement of 350mV-
