在对储能系统进行调度时,存在风能最大功率获取速度慢、输出功率与储能系统充/放电结果相差大的问题,为此提出储能系统电力设备变工况的优化运行控制方法。依据电力设备部件之间的动态耦合,建立电力设备目标函数及约束条件,构建电力设备模块化数学优化模型。利用该模型对电力设备部件参数进行优化后,将处于不同运行模式的电力设备以变工况运行方式进行优化运行控制。实验结果表明,通过对该方法进行风能最大功率获取速度测试、输出功率与储能系统充/放电结果对比测试、储能系统频率与设定频率测试,验证了该方法准确性强、有效性高。

When scheduling the energy storage system,there are some problems,such as the slow acquisition speed of the maximum power of wind energy and the big difference between the output power and the charging/discharging results of the energy storage sys-tem.Therefore,the optimal operation control method of the power equipment in the energy storage system under variable work-ing conditions is proposed.According to the dynamic coupling between power equipment components,the objective function and constraint conditions of power equipment are established,and the modular mathematical optimization model of power equipment is constructed.After using this model to optimize the parameters of power equipment components,the power equipment in differ-ent operating modes are optimized and controlled in variable operating mode.The experimental results show that the method is accurate and effective by testing the maximum wind power acquisition speed,comparing the output power with the charging/dis-charging results of the energy storage system,and testing the frequency of the energy storage system and the set frequency.
