摘要
Abstract
The output power of photovoltaic cells changes with the external environment (light intensity, ambient temperature) and load. It is necessary to track the maximum power point of solar cell array rapidry and accurately to improve the utilizabon efficiency of solar cell array. In order to further improve the efficiency of photovoltaic power generation system, a method based on fuzzy logic dual-loop control of the maximum power point tracking of photovoltaic power generation system was presented, which added an inner loop of the fuzzy control based on the former fuzzy control. The simulation verifies that the double-loop fuzzy control method is more efficient and can effectively eliminate the oscillations around the maximum power point. The results show that this maximum power point tracking algorithm can track the maximum power point of photovoltaic power generation system rapidfy and accurately and can improve the static and dynamic performance of the photovoltaic power system.关键词
