基于自寻优+PI算法的最大功率点跟踪
Maximum power point tracking based on automatic optimization +PI algorithm
摘要
Abstract
In order to improve the stability and efficiency of solar photovoltaic power generation systems,it needs to track the maximum power point of photovoltaic cell.The mathematical models of the photovoltaic cells and DC/DC conversion circuit were set up.Through comparing incremental conductance method and perturbation method of observation,a kind of automatic optimization + PI control method was proposed.The simulation results show that the automatic optimization +PI control algorithm can quickly and accurately track the maximum power point,solve the poor stability of common methods and improve the stability of solar photovoltaic power generation system and energy utilization efficiency.关键词
