摘　　要：在光伏发电是新能源应用的一种重要形式,不仅能有效缓解传统煤炭资源的消耗,还能持续为地区电网供电,提高地区电网的供电可靠性。但是光伏电站的建设成本较高,1为此需要提高光伏阵列的运行可靠性,但是目前所使用的最大功率跟随算法普遍存在缺陷,使得光伏发电系统在最大功率搜寻的过程中存在振荡、偏离等问题,为此,本文将提出一种变步长的最大功率跟踪算法(MPPT,Maximum power point tracking)来改善传统最大功率跟踪算法存在的问题。Photovoltaic power generation is an important form of new energy application. It can not only effectively alleviate the consumption of traditional coal resources, but also continue to supply power to the regional power grid and improve the power supply reliability of the regional power grid. However, the construction cost of photovoltaic power plants is relatively high. Therefore, it is necessary to improve the operational reliability of photovoltaic arrays. However, the current maximum power follow algorithm generally has defects, which makes photovoltaic power generation systems have problems such as oscillation and deviation in the process of maximum power search. Therefore, this article will propose a variable step size Maximum power point tracking algorithm(MPPT, Maximum power point tracking) to improve the traditional maximum power tracking algorithm.
