摘要
针对光伏电池的最大功率点跟踪(MPPT)影响着光伏系统的发电效率,本文对光伏阵列的功率输出特性曲线进行了建模仿真分析,根据MPPT的目标是保持光伏阵列输出电压一直保持在最大功率点处,重点分析在光伏阵列出现局部阴影情况时的,光伏阵列的P-V输出特性为多峰曲线情况下,提出了一种基于改进的模拟退火粒子群算法的最大功率点跟踪控制方法,将模拟退火算法思想融入到粒子群算法中,改善粒子的探索能力,提升了最大功率点跟踪算法的收敛速度和精确性。
The maximum power point tracking for photovoltaic cells（MPPT） affect the generation efficiency of photovoltaic system, power output characteristic curve of PV array in this paper are modeling and simulation analysis,according to the goal of MPPT is to keep the output voltage of the photovoltaic arrays has been maintained at the maximum power point,focuses on the analysis of local shadow situation in photovoltaic array,P-V output characteristics of PV arrays for multi peak curve case,put forward a kind of control method of maximum power point tracking simulation annealing improved particle swarm algorithm based on simulated annealing algorithm,the thinking into the particle swarm algorithm,improved particle exploration ability,improve the convergence speed of the maximum power point tracking algorithm and accuracy.
