A confluence of industry drivers including increased deployment of renewable generation, cost for managing grid peak demands, and capital investments in grid infrastructure for reliability and smart grid initiatives are creating a new interest in electric energy storage systems. This paper will review the role and value of energy storage systems to the electric grid. It will present findings from...
Pioneering efforts in showing how electricity energy storage can be a valuable asset in a Smart Grid Distribution System have been in process for the last few years. Several demonstration projects were completed to show how substation loading could be controlled and managed to delay upgrades. The next step was to show how the load deferral benefit could be combined with distribution circuit automation...
The smart grid concept was introduced to the US utility industry by the Department of Energy (DOE). It was based on the visions of DOE's Grid 2030 and National Electric Delivery Technologies Roadmap. The debate over what constitutes a smart grid is still emerging. Nevertheless, we all agree that smart grid concept is complex and contains many interdisciplinary technologies and strategies. It is difficult...
Electric power generation is the second-largest category of greenhouse gas emissions in California, next to transportation. California's administration, legislature, and energy regulators have adopted aggressive targets for renewable energy due to heavy reliance on natural gas as a fuel for electric generation, which will result in profound changes in markets and system operations. The growth of renewable...
Wind generation has been recognized as one of the most important components in Renewable Portfolio Standard (RPS). It becomes a critical task for the power engineers to find solutions in integrating wind generation reliably and economically with the power grid. The intermittency of wind generation and the potential need for adequate transmission expansion are the major concerns in wind technology...
Southern California Edison Company, as well as the other California investor owned utilities are mandated to increase their Renewable Portfolio Standard to 20 percent by 2010 and by the Governor's Executive Order to 33 percent by 2020. When achieved, these types of energy resource assets potentially represent a significant means to meet State energy and environmental objectives. Edison is also embarking...
Flywheel-based energy storage is being introduced on a large scale (20 MW) for providing grid frequency regulation in deregulated markets. The ISOs have already introduced, or are in the process of introducing, market rules and tariffs to comply with FERC Order No. 890 to allow new competitive technologies to participate in the markets. Analysis of more than one year of operating data shows flywheel-based...
This is a panel session to be presented at the IEEE General Meeting 2010. The subject is the design, objectives, and full description of the new National Science Foundation engineering research center denominated FREEDM - the Future Renewable Electric Energy Management center. The focus of this presentation is the reliability of the FREEDM system. The main points in the verbal presentation are: 1)...
