摘要 对储能电站并网测试技术进行了深入研究,针对光储电站中MW级电池储能系统的有功、无功控制能力及功率响应时间进行测试,分析比较不同功率切换下的储能响应时间。首先对光储电站的结构进行介绍,包括光储电站电气接线图、储能系统组成及储能系统通信方案;然后分别对储能电站的有功和无功调节能力、充放电转换时间和储能系统容量进行测试,并对储能调节光伏跟踪计划出力进行测试。对测试结果进行定量分析可以看出,通过就地监控软件设置储能控制指令,储能分系统的功率切换时间在100 ms以内,通过光储电站联合调度管理系统下达功率指令对储能电站进行出力控制时,功率指令响应时间在1.5 s以内。 We investigated the test technology for grid-connected energy storage power station in detail. The active or reactive power control ability and power response time were tested, and the response time under different power control instructions was analyzed and compared. First, the structure of the PV/battery station was introduced, including the elec- trical wiring diagram, the composition of energy storage system, and the energy storage system's communication scheme. Then, the active and reactive power regulation capacity, charge-discharge conversion time, and energy storage system ca- pacity of the storage power station were tested, and the function of energy storage system help PV system to track programmed output was tested. The quantitative analyses of the results reveal that the energy storage system's power switching time is less than 100 ms when the control command is set through local monitoring software and the switching time is less than 1.5 s when the control command is set through PV/Battery station's joint scheduling management system.
