摘要： 局部遮阴条件下光伏阵列P-V特性引起的多个极值点使常规的最大功率点跟踪(MPPT)算法失效。针对上述问题，提出一种基于粒子群优化算法的控制方法，以解决局部遮阴下的最大功率跟踪问题。实验结果显示，光伏模板的输出电压被稳定地控制在最大功率点附近，证明算法是有效的。

Abstract: Under partially shaded conditions, the P-V curve of PV arrays has the characteristics of multi-summit, which makes the Maximum Power Point Tracking(MPPT) failed. Aiming at above problem, this paper proposes a control algorithm based on Particle Swarm Optimization(PSO) algorithm for solving maximum power point tracking problem. Experimental results show that output voltage of PV system is maintained near maximum power point, and the algorithm is effective.

Key words: Maximum Power Point Tracking(MPPT), Particle Swarm Optimization(PSO) algorithm, partially shaded conditions
