摘要
提出了一种适用于全钒液流电池-电化学电容器(VRB-EC)混合储能系统(HESS)的控制策略,分析了EC的最优配置数量及HESS的最小成本。根据风电预测数据设计HESS总充放电功率,通过设定EC的动作区间以降低对VRB的损耗,通过排序法实现对VRB各单元充电任务的合理分配。基于某风电场30 d实测及预测数据,仿真分析了EC配置数量对HESS成本的影响,得到了HESS的最优配置及最小成本,为工程应用中VRB-EC混合储能系统运行方式的制定和配置的选择提供了参考依据。
A control strategy for the HESS（Hybrid Energy Storage System） composed of all-VRB （Vanadium Redox flow Battery） and EC（Electrochemical Capacitor） is proposed,and the optimal quantity of configured ECs and the minimum cost of HESS are analyzed. The total charge/discharge power of HESS is designed based on the wind power forecast data,the EC action interval is set to reduce the loss of VRB ,and the sorting method is applied to reasonably distribute the charging task for each VRB cell. According to the measured and forecasted data of a wind farm for 30 days,the influence of configured EC quantity on the HESS cost is simulated and analyzed,and the optimal quantity of configured ECs and the minimum cost of HESS are obtained,which can be referred during the engineering of VRB-EC HESS project for its operation mode design and EC confizuration.
