Its regulation and control are difficult, and large-scale operation will bring hidden dangers to the safe and stable operation of the power grid. In order to solve the problem of active power imbalance in the regional power grid, this paper uses the method of adding energy storage at the power plant side to enable the energy storage system to participate in the grid frequency modulation, and adjust the active power output of the frequency modulation power supply in the grid in real time, so as to achieve the functions of fast frequency regulation speed, high accuracy, and strong ability to frequently change the direction of power regulation.
