Performance of Batteries in Grid Connected Energy Storage Systems
This paper outlines important considerations for evaluating the battery system component of an ESS intended for grid support applications. These considerations include general and application-specific performance parameters to establish a battery system’s ability to meet baseline performance goals. Important to these considerations are not only the methods of testing, but the knowledge and capability of the organization conducting these evaluations. The devices under the scope of this document are battery systems, which are a component of an ESS that provides the overall storage mechanism.
