摘要
光伏阵列最大功率点跟踪(MPPT)技术是光伏发电应用的关键技术之一。本文基于近年来学界研究成果,对实际应用最多的变步长电导增量法和扰动观察法两种MPPT技术进行优化设计,并详细对比验证了两种改进方法特性。对比仿真和实验结果表明,改进算法均能快速准确地实现最大功率跟踪,其中改进的扰动观察法因算法简单更适合实际产品使用。
Photovoltaic array maximum power point tracking technology is one of the key technologies of the application of photovoltaic power generation. In this paper,based on the academic research,the variable step length incremental conductance algorithm and the perturbation and observation algorithm MPPT technologies which are the most practical application algorithm were optimized and the advantages and disadvantages are compared in detail.Comparing the results of simulations and experiments,the improved perturbation and observation algorithm could be more accurately and faster track the maximum power point,and is more suitable for the actual product.
