基于防突变负载的光伏并网发电最大功率点跟踪方法与实验研究
Study on maximum power point tracking method and experiment of photovoltaic power based on sudden changing load
摘要
Abstract
Photovoltaic power system is easily influenced by unstabilizing factors, which can cause the misjudgment of maximum power point tracking.According to the effect of the changing load on the maximum power point tracking of photovoltaic power, a new maximum power point tracking method is presented to prevent the misjudgment of maximum power point tracking.The method can test and calculate maximum power point correctly which is superposed to the power of maximum power point, and compensate for power in the process of the maximum power point tracking, which can avoid the phenomenon of misconception.The experiment results show that, the improved method can avoid the misjudgment and obtain better? tracking under the changing load.Compared with traditional perturbation and obser-vation, the new control method of maximum power point tracking improves the efficiency of grid-connected PV.关键词
