摘要
介绍了风光互补发电系统的拓扑结构.基于该系统的输出特性,研究了一种基于分时跟踪的最大功率跟踪控制方法.以风速和日照强度的预测值为依据,对风力和光伏发电系统的输出功率进行分时跟踪控制,从而保证风光互补发电系统的最大功率输出.最后,建立了风光互补发电系统的仿真模型.仿真结果表明,所设计的控制方法可以实现对风光互补发电系统输出功率的跟踪控制.
The topology of the wind-solar complementary power generation system is introduced.Based on the output characteristics of this system,a maximum power point tracking control strategy based on time-sharing tracking is studied.Taking the prediction data of wind speed and sunshine intensity as a basis,the power output of wind power and photovoltaic power generation system is controlled by time-sharing tracking,so that the maximum power output of wind-solar complementary power generation system is ensured.Finally,a simulation model of wind-solar complementary power generation system is established.The simulation result shows that the designed control strategy can be utilized to realize the tracking control of the power output of the wind-solar complementary power generation system.
