The application of BESS in load shedding scheme

With new developments in battery technologies, increasing application of Battery Energy Storage System (BESS) in power system is anticipated in near future. BESS has already been used for primary frequency regulation in the past. This paper examines the feasibility of using BESS with load shedding, in application for large disturbances in power system. Load shedding is one of the conventional ways during large disturbances, and the performance of frequency control will increase in combination with BESS application. According to the latest news, BESS which are applied in high power side will be employed in practice in next 5 year. A simple low order SMR model is used as a test system, while an incremental model of BESS is applied in this paper. As continuous disturbances are not the main concern in this paper, df/dt is not considered in article.
