摘　　要：随着高比例新能源接入,电网的安全稳定运行面临着巨大的挑战。当电网出现有功缺额等问题时,新能源场站功率控制精度、响应时间等相关指标不满足要求,不能快速参与电网调峰及系统电压频率的调节,因此,介绍了电化学储能电站接入电网的测试方法,并针对测试过程中通信配置不合适导致报文拥堵,装置收到指令时间不同步引起响应时间过长、功率调节不到位等问题,通过修改“报文采集步长”,优化整改措施。结果表明提出的系列测试方法可有效解决测试过程中出现的响应时间过长、功率调节不到位等问题,显著提升储能电站接入电网的测试效率。With the increasing integration of renewable energy sources,the safe and stable operation of the power grid faces significant challenges.When issues such as active power deficits arise,the precision of power control and response time of renewable energy stations do not meet requirements,hindering their ability to quickly participate in peak shaving and regulate voltage and frequency within the grid.This paper elaborates on the testing methods for connecting electrochemical energy storage stations to the power grid.It addresses issues such as inappropriate communication configurations and unreasonable software logic during testing,proposing corresponding optimization measures like"stop upon reaching limits."Validation of these measures shows that the proposed series of testing optimizations can effectively resolve problems related to excessive response times and inadequate power regulation during testing,significantly enhancing the efficiency of testing for energy storage stations connected to the power grid.
