In this paper, a frequency control method for off-grid operation of energy storage systems has been proposed with virtual synchronous control. Firstly, the single-machine mathematical model of the power converter system (PCS) controlled by the virtual synchronous machine is established. Secondly, energy storage systems based on virtual synchronous control have been analyzed. Finally, two battery energy storage systems (BESS) were built on the SIMULINK simulation platform to realize island
