摘要

以太阳电池的物理数学模型为研究对象,通过对太阳电池输出特性的分析,提出一种基于电导增量法的无级电压扰动叠加自适应的最大功率点跟踪（MPPT）简洁控制方法,在PSIM仿真环境下,与常规的固定步长电导增量法进行对比分析。仿真研究及实验结果表明,该方法在太阳光照强度或负载突变及稳态时均能快速有效实现最大功率跟踪控制,为光伏发电MPPT控制的设计应用提供了参考。

Abstract

Taking the physical and mathematical model of photovoltaic cells as the research object, a concise control method of maximum power point tracking （MPPT） with stepless voltage disturbance superposition adaptive based on conductance increment method is proposed by analyzing the output characteristics of photovoltaic cells. In the PSIM simulation environment, it is compared with the conventional fixed step incremental conductance method. The simulation results show that the proposed method can achieve maximum power tracking control quickly and effectively in the case of sudden change of sunlight intensity or load and steady state, which provides a reference for the design and application of MPPT control for photovoltaic power generation.
