Abstract: Photovoltaic power generation and wind power generation are characterized by intermittenency and volatility.Combining the two can effectively alleviate power supply imbalance and improve the reliability of power generation system.In this paper，the photovoltaic electronic module，wind electronic module and battery sub-module in wind-solar complementary power generation system are analyzed and modeled，and the maximum power tracking simulink simulation of photovoltaic power generation system and wind power generation system is completed.On this basis，a wind-solar complementary coordinated control and grid connection strategy is proposed，and the simulation results verify the feasibility of the control strategy.

Key words: wind-solar complementary power generation, maximum power tracking, coordinated control, interconnection

摘要： 光伏发电、风力发电具有间歇性和波动性的特点,将两者结合起来,可以有效缓解电能供应不平衡矛盾,提升发电系统的可靠性。本文中首先对风光互补发电系统中光伏发电子模块、风力发电子模块和蓄电池子模块进行了分析和建模,完成了光伏发电系统和风力发电系统的最大功率跟踪simulink仿真。在此基础上,提出一种风光互补协调控制与并网策略,仿真结果验证了控制策略的可行性。
