Bulk energy storage devices and fleets of electric vehicles are being proposed as a resource for regulation services. To use energy storage for regulation services, energy storage is expected to operate seamlessly, in concert with existing regulation resources and existing regulation operation processes. This project identified, collected, and initially analyzed operating data from the California Independent System Operator (ISO) to address the use of energy storage for regulation services.
This EPRI research project provides background information for California ISO consideration. While a proposed regulation correction algorithm is applied to the collected operating data, in no way is the algorithm a certified algorithm for actual use in a production system. The collected operating data covers a full week (June 6 through June 12, 2010). The depth and breadth of the identified and collected operating data was selected to facilitate current and potential future work.
