摘　　要：以铅酸电池和全钒液流电池组成的混合储能为例,针对常规机组调频的固有特点,研究了混合储能装置配合传统机组参与自动发电控制(AGC)的充放电策略和最优容量配置计算方法。首先,针对常规机组调频的特点,提出一种考虑抑制反向调频、死区振荡、储能装置过度放电、荷电状态水平强制归位的优化控制策略;其次,综合考虑配置储能装置成本和发电侧调频收益,构建储能装置系统经济运行优化函数的容量规划模型;最后,根据某发电厂实际运行数据进行仿真计算,利用粒子群优化算法求解,结果表明该方法的调频效果、运行经济性等比常规机组调频均有提升。By taking the hybrid energy storage system（ESS）composed of the value regulated lead acid（VRLA）battery and the vanadium redox battery（VRB）as an example,in view of the intrinsic characteristics of conventional unit frequency regulation,a charge and discharge strategy and optimal capacity planning of hybrid ESS participating in the automatic generation control（AGC）by assisting conventional units is studied.Firstly,according to the characteristics of conventional unit frequency regulation,an optimal control strategy taking into account the suppression of reverse frequency regulation,dead zone oscillation,ESS over discharge,and forced state of charge（SOC）homing is proposed.Secondly,considering the cost of ESS configuration and the frequency regulation income of power generating units,a capacity planning model is developed.Finally,based on the particle swarm optimization（PSO）algorithm,the simulating calculation of the actual operation data of a power station is conducted.The results show that the frequency regulation performance and the running cost of the method are both better than those of the conventional unit frequency regulation.
