In transmission lines, due to the influence of line impedance, it is difficult for energy storage power station systems to allocate power reasonably according to capacity. In order to better promote the stable operation of black start, this article proposes a battery power distribution scheme for energy storage power plants based on improved Virtual Synchronous Generator (VSG). This scheme first introduces virtual impedance to eliminate bus voltage fluctuations caused by line impedance, in order to improve the accuracy of power allocation in energy storage power station systems; Then, in response to the problem of uneven power distribution among multiple energy storage units in parallel in an energy storage power station due to the influence of line impedance, the power transmission and circulating characteristics of multiple energy storage devices in parallel were analyzed to continuously improve the black start system. Finally, experimental analysis was conducted using Matlab/Simulink and semi simulation platforms to verify the effectiveness of the proposed strategy, which can improve the stability and economy of system operation.
