Texas grid operator deploys Vehicle-To-Grid Aggregation System
SwRI Develops ERCOT-Qualified Vehicle-To-Grid Aggregation System
by Renew Grid on January 15, 2014
San Antonio-based Southwest Research Institute (SwRI) has deployed a vehicle-to-grid aggregation system qualified by the Electric Reliability Council of Texas (ERCOT) to manage charging activities for a fleet of electric delivery trucks.
SwRI says the system suspends vehicle charging when the electric grid frequency drops too far below 60 hertz, the normal operating frequency. The institute adds that the smart grid system demonstrates enabling technologies to support stable electric power delivery.
According to SwRI, it developed the aggregation system as part of an ERCOT pilot program for fast response regulation services (FRRS), with the goal of providing extremely quick response to grid frequency deviations. FRRS is designed for services that can respond nearly instantaneously to grid events, helping to slow frequency decay and ultimately reverse it sooner than current frequency regulation services can. The institute reports that electric vehicle batteries can respond in milliseconds, making them a perfect asset for FRRS services.
The technology is particularly useful for integrating green technologies into energy infrastructure, SwRI notes.
