提出一种面向电力系统调控需求的储能系统集中控制策略,以提高电网接纳风电规模,减少弃风电量。同时根据储能系统荷电状态(state of charge,SOC),对储能系统充放电指令进行实时修正,防止储能系统过充过放,优化其运行性能。建立了储能系统经济性评估模型,用以评估储能系统提高风电接纳的运行经济效益。以收益最大为目标,确定储能系统容量配置。基于某地区实测数据对上述控制策略和经济性评估模型进行验证,结果表明提出的面向系统调控需求的储能系统控制方法能够扩大风电入网规模,有效利用电网可接纳风电空间。

A kind of centralized control strategy for regulatory requirements oriented energy storage system for the power system was proposed to improve scale of the power grid taking in wind power and reducing curtailed wind power energy. Ac-cording to state of charge (SOC)of the energy storage system,charge and discharge instructions of the system were revised in real time for preventing over charge and over discharge and optimizing its operational performance. Evaluation model for economy of the energy storage system was established for evaluating operational economic benefits of the system improving wind power adoption. Taking maximum profit as a target,capacity configuration of the energy storage system was deter-mined. Based on measured data in some region,verification on the control strategy and evaluation model was conducted. Results indicate that the control method for energy storage system could enlarge wind power networking scale and effectively use space of the power grid taking in wind power.
