摘　　要：保持频率稳定是电力系统正常运行的基本要求。未来,储能电源将成为电力系统中必不可少的辅助调频手段。为比较不同类型储能电源参与电网调频的效果,以常用的电池储能电源(BESS)、电容器储能电源(CES)和超导磁储能电源(SMES)为研究对象,建立了包含储能电源的经典两区域电力系统模型;提出储能电源参与电网调频的运行模式为有功/无功功率(PQ)控制;最后,通过模拟两种不同的负荷扰动,分析了自动发电控制(AGC)-BESS、AGC-CES、AGC-SMES和仅含AGC四种组合方式参与电网调频的控制效果;同时,对后续研究工作进行展望。Keeping the frequency stable is the basic requirement for the normal operation of power system. At present,the appropriate energy storage has been promising as an auxiliary resource for power system frequency regulation. In order to compare the effects of different energy storage power supplies on the frequency regulation,the classical two-area power system model with the energy storage is proposed in this paper. Three kinds of energy storage are analyzed,including battery energy storage system（ BESS）,capacitor energy storage system（ CES） and superconducting magnetic energy storage system（ SMES）. Fixed power control（ PQ control） is applied in the auxiliary service of ESS in frequency regulation. Two different kinds of the load perturbance analysis are performed to compare four different mixes of AGC and energy storage,such as automation generator control（ AGC）-BESS,the AGCCES,the AGC-SMES and the only AGC. At the same time,the future work is prospected.
