A Control Method Design of VRB in Stand-alone Wind Power System
With the constant expansion of wind power,in order to improve the stability of stand-alone wind power system,this paper presented a new style of environmental vanadium redox flow battery(VRB) energy storage system,which is capable of decreasing power fluctuations.According to equivalent VRB mathematical model,this paper designed a control method of VRB based on the analysis of relationship between the state of charge(SOC) and voltage.According to results of simulations on stand-alone wind power system with VRB,under the circumstance of transient change of wind speed and load,the system can ensure a stable supply to load through the control of VRB.
