      MPPT Analysis of Photovoltaic Power Generation System Based on P&O and IC Method

      摘要:
      在光伏发电系统中,为提高电池的利用率,需要实现快速精确的最大功率点跟踪(MPPT)控制.在众多的MPPT方法中,扰动观察法和电导增量法由于原理简单、易实现等优点而一直成为研究及选用较广泛的方法为促进光伏电池的MPPT算法进步,提高传统方法性能和控制效果,在传统扰动观察法和电导增量法的基础上,对近年来这2种方法的改进算法,以及分别与其他方法的结合使用情况进行详细分析,比较出各自优缺点并对未来的MPPT方法做出展望.
      Abstract:
      In photovoltaic (PV) power generation systems,in order to improve battery utilization rate,fast and accurate control method of maximum power point tracking (MPPT) is very important.Among numerous MPPT control methods,perturbation and observation (P&O) method and incremental conductance (IC) method,due to simple principle and easy implementation,have been widely apphed in research and engineering projects.In order to improve performance and control effect of photovoltaic cell MPPT algorithm,detailed review of recent algorithm improvement and combined use with other methods are performed.Advantages and disadvantages of different improvement are discussed and future prospects of MPPT method are introduced.
