光伏系统中扰动观察法的控制方法研究
Study of Perturb & Observe Control Methods in Photovoltaic System
摘要
Abstract
According to the output characteristics of photovoltaic cells, theory analysis of Perturb & Observe (P&O) control methods including direct control and PI control was made based on the hardware platform of Boost circuit Then simulation models of P&O on Boost circuit were established by Simulink. Through the simulation result, comparison of the two P&O control methods was carried out Further, the developed 1.5 kW dual-stage photovoltaic grid-connected inverter based on Boost circuit was applied for experiment to verify the effectiveness of the presented P&O control methods.关键词
