Control Method of Parallel Vanadium Batteries Operating in Energy Stored Wind Farm System

Abstract:

Wind farms with vanadium battery energy storage system are recognized and welcomed. Against the phenomenon of current distribution unreasonable while vanadium batteries are directly paralleled, a control strategy of vanadium battery parallel based on the state of charge (SOC) is proposed. The current control formula is given in this paper. Vanadium batteries are paralleled to adjust the power grid at the exit of wind farms by the bidirectional DC/DC converter. A wind farm model with vanadium battery energy system is simulated on MATLAB/Simulink. The simulation results show that this system can adjust the power grid of wind farms and achieve the goal that the charging and discharging of vanadium batteries are determined by their SOC, avoiding the overcharge or over-discharge.
