基于β参数的混合控制策略光伏系统MPPT算法研究
Maximum power point tracking algorithm of photovoltaic system based on β-Parameter mixed control strategy
摘要
Abstract
Maximum power point tracking is one of key techniques in the photovoltaic power generation system.A mixed control strategy based on β-parameter is proposed in this paper in order to reduce misjudgment and oscillation at maximum power points (MPP) under traditional power prediction algorithm when illumination changes suddenly.The tracking process is divided into two phases with the value of β.At different phases,the variable step perturbation method and the fuzzy control method are used to track the MPP accurately so as to avoid the misjudgment when the light is not uniformly changing.Consequently,the tracking accuracy is improved under a steady state.The maximum power point tracking model of PV system is built on the Matlab platform,and then the static and dynamic properties are simulated.The simulation results show that the proposed strategy exhibits satisfactory static property and excellent dynamic performance in the successful track of MPP.关键词
