A Review of Partial Shading MPPT Algorithm on Speed, Accuracy, and Cost Embedded

Abstract

This paper describes several maximum power point tracking algorithms for partial shading conditions that have detrimental effects on photovoltaic systems. The method used was a literature review of articles from reputable publishers. Fifty-two articles were obtained after meeting the established criteria for selection. The literature review focused on the ability of the maximum power point tracking algorithms to overcome partial shading conditions in terms of tracking speed, tracking accuracy, efficiency and implementation complexity. Some algorithms were recommended to be applied for maximum power point tracking, including the single swam algorithm and the perturb and observe algorithm, the enhanced adaptive step size perturb and observe algorithm, the novel adaptable step incremental conductance algorithm, the improved bat algorithm and fuzzy logic controller algorithm and the particle swarm optimisation with one cycle control algorithm. In terms of implementation complexity, these five algorithms are categorised as medium-complexity algorithms, which can be characterised by low cost, high efficiency and even 100% high tracking speed and accuracy with a minimum number of sensors used.
