全钒液流电池SOC估算方法研究

SOC estimation method research of all vanadium redox flow battery

荷电状态(state of charge,SOC)估算是储能系统研究的核心内容之一,关系到微电网的功率控制与能量管理策略。简述了适用于全钒液流电池SOC的表征方法和估算方法,分析了这些方法的优缺点及适用范围,对全钒液流电池SOC估算的发展趋势做出了展望。

The research core of energy storage systems, estimation of the SOC, concerns the strategy of the power control system （PCS） as well as the energy management system （EMS） in the micro grid. Most of the general methods both used to characterize and estimate the SOC of the VRB in recent years were reviewed. The advantage and disadvantage along with the applicability of the mentioned methods were analyzed. The outlook of the estimation methods used for VRB was made.
