一种基于变步长电导增量法的自适应MPPT控制策略
A type of MPPT control strategy based on variable step-size incremental conductance algorithm
摘要
Abstract
Photovoltaic cell is one of the most fundamental components in the photovoltaic power system,whose output characteristic is partly depended on the corresponding external working environment.Then,utilizing the optimized maximum power point tracking (MPPT) method is beneficial to improve the entire efficiency of the photovoltaie power system.This paper presents a kind of MPPT control strategy according to the indelible defect in terms of instantaneity and fault-tolerant in traditional incremental conductance algorithm.Specifically,the proposed algorithm provides a novel step-size adjustment method,which can guide the modulation of the step-size based on the variable external environment.Meanwhile,it can address the issues of slow dynamic response and misjudgment in traditional incremental conductance algorithm under the polytropical illumination intensity.Finally,a series of computer experiments are conducted to verify the effectiveness and validity of the entire scheme.关键词
