Wind Storage Enhanced Transmission Research and Development - Final Project Report

Publication Number:    CEC-500-2013-044

Abstract:

A project team led by Southern California Edison Company analyzed Southern California Edison’s electricity system to identify existing transmission interconnection locations that would benefit from integrating energy storage technologies. The team investigated system contingencies and possible wind storage impacts on the system. Energy storage and converter manufacturers were selected using the Request for Information process. After determining which manufacturers could provide the best technology for implementation, the team selected the energy storage devices that satisfy the criteria for providing promising, commercially viable, economically feasible, and scalable solutions. The team also provided a pathway for commercialization as well as a Technology Transfer Plan. Implementing energy storage devices into the Southern California energy grid will help California meet its Renewable Portfolio Standard goal of obtaining 33 percent of its electricity from renewable sources by 2020, which will reduce greenhouse gas emissions and other air emissions that contribute to air pollution.

The goal of the project was to quantify the benefits and costs of integrating energy storage technologies in the Southern California Edison service area. Three case studies representing three critical power system issues were selected for more detailed analysis and feasibility studies. Two cases in the Tehachapi and Palm Springs wind resource areas were analyzed for wind‐related voltage/frequency instability and path congestion, respectively. The third location studied was the South Bay area of Los Angeles County and addressed power quality issues for non‐renewable facilities. For each location, major issues were identified that impacted power quality and transmission reliability.

Three promising energy storage technologies were selected, and it was determined that a hybrid combination of these technologies would provide the best solution. The authors recommended that the State of California, Southern California Edison, and other stakeholders pursue an energy storage
