摘　　要：针对风光储联合发电系统的运行特点,基于分段调频控制的理念,提出了一种风光储联合发电系统参与电力系统二次调频的控制策略。该控制策略根据区域控制偏差ACE就调频控制的紧急程度进行划分,在不同控制区域使用不同的有功控制方式,实现对联合发电系统出力的精细化控制,最大程度利用风电及光伏发电,保障储能电池SOC运行在合理范围。仿真分析验证了所提调频控制策略的可行性、有效性及经济性。This paper proposes a control strategy of the wind-PV-storage power generation system taking part in second control of power system based on partition frequency control considering operating characteristics of the wind-PV-storage power generation system.This control strategy distinguishes different emergency degree of frequency control according to area control error（ACE）,utilizes different active power control mode in different control area,exerts detailed control on the joint generating system,reduces the limitation on wind power and solar power and guarantees the SOC operating within reasonable limits.Simulation analysis verifies the feasibility,effectiveness and economy of the proposed strategy.
