Analysis of Possibility of Replacing Self-starting Generator with BESS

Abstract

Recently, Many papers have been published on other's utility of the existing BESS (Battery Energy Storage System) equipment that stabilizing the output of the renewable energy and adjusting the frequency of the power system. In 2013, the EPRI has reported a study of the primary power plant starting using BESS for the replacement of two black start generators of American Electric Power (AEP) that will be torn down. As the social interest in the power outage has increased since wide-area blackout in South Korea in 2011 it is time to research not only a reliability of the power restoration plan but also reducing power restoration time. In case of wide area black-out, the primary transmission line should be energized at first after opening all circuit breaker in power system. Since these transmission lines are long-distance and no-load, various problems may befall in the process of energizing. In this paper, the restoration process using BESS for primary transmission line was analyzed. PSCAD / EMTDC was used for simulation.
