风光互补发电系统最大功率跟踪综述

摘要

风光互补发电系统的运行需要快速准确地进行最大功率点跟踪，为此综述了风光互补发电系统最大功率点跟踪的几种方法，包括在太阳能电池阵列部分日益成熟、改进和优化策略较多的扰动观察法、电导增量法和恒压控制法；风力发电机部分的叶尖速比控制法、功率信号反馈法、扰动观察法，分别说明了各种跟踪控制方法的优点和不足之处。最后探讨了最大功率点跟踪控制方法的发展思路，对该领域今后的研究方向做了展望。%The Maximum Power Point Track ( MPPT ) of the wind-solar hybrid generation rapidly and accurately was necessary and it can increase the output power. This paper summarizes the methods of MPPT, the solar panels MPPT control technology including the Perturbation and observation control, incremental conductance control and constant pressure control. the wind turbine including tip speed ratio control, power signal feedback control and perturbation and observation control. Points out the limitations and notes of those methods. Finally, some feasible thoughts with new technologies for wind-solar hybrid generation are discussed and its study direction in the future is also looked ahead.
