压缩空气储能是一种优质的电网调节电源,其调峰能力较强而调频能力较弱,为缓解可再生能源发电大量接入所带来的频率问题,利用功率型飞轮储能辅助压缩空气储能机组运行,提高压缩空气储能机组的调频能力。给出了发电机组的简化频率计算模型、飞轮储能系统及压缩空气储能机组模型、区域电网频率控制模型,对不同飞轮容量配置模型组成的区域电网频率特性进行了仿真实验。结果表明:飞轮储能系统的加入提高了压缩空气储能机组的一次调频性能。
Compressed air energy storage(CAES)is a high-quality power source for grid regulation with strong peak-regulating capability and weak frequency-regulating capability,in order to alleviate the frequency problem caused by the large scale integration of renewable energy power generation.In this regard,power type flywheel energy storage was utilized to assist the operation of compressed air energy storage units to improve their frequency regulation capability.A simplified frequency calculation model of generating units,flywheel energy storage system,compressed air energy storage unit model and regional power grid frequency control model were given.Simulation experiments were carried out on the frequency characteristics of regional power grid composed of different flywheel capacity configuration models.Results show that the inclusion of flywheel energy storage system improves the primary frequency modulation performance of compressed air energy storage unit.
