基于改进功率预测算法的变步长光伏MPPT研究
Variable step disturbance observation based on the improved power prediction algorithm
摘要
Abstract
Photovoltaic array maximum power point tracking is one of the key technologies of photovoltaic power generation. The traditional power prediction algorithm would produce misjudg-ment when sudden illumination changes. The rate of change of illumination is introduced and the modeling of illumination change is more accurate, thus the traditional power prediction algorithm is improved. At the same time, the step adjustment coefficient is increased to improve the tracking speed of the algorithm. The simulation results show that the improved algorithm can achieve the maximum power point tracking quickly and accurately.关键词
