A Black Start Simulation Method with Energy Storage Assistance Systems in Wind Power Consumption

With the rapid development of energy storage technology, energy storage power stations have the advantages of fast response speed, flexible regulation of power output of the power grid, and unlimited installation location. An improvement simulation method for black start considering energy storage assistance system is proposed, adding an energy storage assistance system on the black start power supply side to help maintain the voltage and frequency of each bus node in the black start path within the allowable range during the load recovery phase, and electromagnetic transient modeling simulation is used to select the appropriate energy storage capacity, then the effect of the improved simulation method is verified by simulation. The results show that the proposed simulation method can effectively improve the security of the black start scheme from the black start power supply side.
