Abstract
Coal-fired power units show defects in meeting the demands of maintaining power system frequency stability. This is mainly due to their inherent characteristics and a continuous increase in renewable generation. Battery Energy Storage System (BESS) has such advantages as fast response and precise tracking, thus may be a new frequency regulation method. On basis of the principle of energy storage for regulation, capacity configuration of energy storage is made as an alternative to coal-fired power unit accounting for both primary and secondary frequency regulation. Example calculations and simulation in MATLAB/SIMULINK are conducted to verify the feasibility of the proposed capacity configuration methods and the reliability of the energy storage system for regulation.
