Abstract:The impact of high penetration of Renewable Energy Source (RES) and the decoupled power-frequency relationship raise the concern for RES participating in the grid frequency regulation. Energy Storage System (ESS) has shown its potential in power system with RES. This paper proposes a new control method of ESS considering the ancillary service efficiency and economical aspects. The proposed state of charge (SoC) feedback control is based on net-zero concept of frequency regulation model. A feedback gain is intr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
