基于模糊PI的光伏发电双MPPT研究
Fuzzy PI Control Based Dual MPPT Control Method for Photovoltaic Power Generation
摘要
Abstract
For the shortcomings that photovoltaic array has nonlinear working characteristic,and traditional MPPT (maximum power point tracking) control is slow in response to change of external environment and has clear power oscillation near the maximum power point,this paper analyzes the maximum power point tracking algorithm,and proposes a fuzzy PI control based dual MPPT control method for photovoltaic power generation system.A dual MPPT system model of photovoltaic power generation under fuzzy PI control is established,the change rules of the system control quantity and the system variables are constructed,and the simulation parameters are designed.Simulation shows that the proposed control method can quickly and accurately track the maximum power point of PV array with good dynamic and steady state performance in changing external environment.关键词
