In order to improve the off grid operation control effect of flexible battery pack of power conversion system (PCS) in energy storage system level, this study proposed a coordinated control method for off grid operation of PCs flexible battery pack with complex load. The capacitor terminal voltage of flexible battery is controlled in advance, and the mathematical model of PCs flexible battery off grid control is established. The compensation method of line voltage drop difference is applied to the off grid control, and the coordinated control of PCs flexible battery under complex load is realized. The experimental results show that the control voltage can be stabilized and the control time is short after the coordinated control method of PCs flexible battery pack is controlled under complex load. It is proved that the control method in this paper is beneficial to the coordinated distribution of power among multiple machines and to ensure good voltage and frequency quality.
