基于分段模糊控制方法的光伏MPPT控制策略研究
Research on MPPT Control of Photovoltaic System Based on the Piecewise Fuzzy Control Method
摘要
Abstract
This paper analyzes the electrical characteristics of PV system, presents a piecewise fuzzy MPPT control method with a combination between constant voltage method and perturbation and observation method. Through the analysis of the constant voltage method and the power-photovoltaic characteristic curve,determined the corresponding voltage range of maximum power point and divided the MPPT control into 4 sections, adopt different control strategies in different sections. A simulation study was conducted. The results show,the system is fast response and running stable,maximum power point tracking effect is good.关键词
