GSO的局部阴影光伏阵列MPPT控制的研究
MPPT for PV array under partially shaded condition based on GSO algorithm
摘要
Abstract
When the PV array is under partially shaded condition,the parallel connection of bypass diode is conducted at both ends of several series solar cells to eliminate hot spot effect,but the P-U characteristic output curve will show multiple peaks.The traditional maximum power tracking method may fail.On the basis of establishing and analyzing the characteristic output curve for multiple peaks problem,the improved GSO algorithm was applied into the MPPT of PV array under partially shaded condition.The simulation results indicate that the improved GSO algorithm can quickly and accurately track the maximum power point and ensure the efficient use of power.Compared with the particle swarm optimization algorithm,the superiority of this method was verified.关键词
