Abstract For the large-capacity energy storage system composed of multiple sets of vanadium redox flow batteries connected in parallel, an optimized power allocation strategy considering the loss is given.This strategy first establishes a power allocation model that takes into account losses, and then takes the system loss and SOC balance as the objective optimization function.And the virtual particle-adaptive differential evolution algorithm (VP-ADE) is used to find the optimal solution under the constraints of meeting the power demand, state of charge (SOC) upper and lower limit, etc. Therefore, the optimal power distribution of the energy storage system is realized.Finally, the strategy of this paper is simulated and verified based on Matlab, and compared with the traditional strategy , the simulation results show that this the SOC of each energy storage unit gradually converge during charging and discharging.
