Research on Control Strategy of Energy Storage System as Black Start Power Supply

With the development of energy storage technology and the continuous expansion of the scale of energy storage power stations, the role of energy storage power stations in improving the recovery speed and stability of the grid after a failure cannot be ignored. This paper establishes an equivalent model of the energy storage system. By analyzing the main problems of frequency and voltage stability in the initial stage of the black start, the control strategy of the energy storage system as a black start power source is proposed. Finally, using DIGSILENT software simulation verifies the feasibility and effectiveness of the energy storage power station as a system black start power source, which provides a certain reference for the application of the energy storage power station in the black start of the power grid.
