Embodiment Construction
[0023] The solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] figure 1 The equivalent circuit diagram of the parallel system composed of N PCS devices for the energy storage system to work in the island mode, where is the output voltage of the ith PCS device, is the output current of the ith PCS device, For the parallel system output voltage, is the equivalent parallel impedance. by is the reference vector, converted to the synchronous rotating coordinate system, the relationship between the parallel compensation voltage and the circulating current power error can be obtained through modeling analysis, as shown in figure 2 shown, where R i and x i are the equivalent parallel resistance and inductive reactance, respectively. It can be seen that there is a coupling term based on the parallel equivalent resistance between the active power and the reactive power of the cir...
