中文摘要:

随着风力发电规模的不断增大,为提高独立风电系统运行的稳定性,本文在该系统中增加了新型环保钒氧化还原液流电池(VRB)储能系统,以有效减少功率波动给系统带来的不利影响。根据VRB等效数学模型,分析了VRB荷电状态(SOC)与端电压之间的变化特点,设计了VRB SOC的控制方法,并对具有VRB储能系统的独立风电系统进行建模和仿真。仿真结果表明,在含有VRB储能系统的独立风电系统中,通过控制VRB SOC可以使系统在风速及负荷瞬变的情况下保证对负荷的稳定供应。

英文摘要:

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.
