摘要：This paper presentsan improved strategy to provide better maximum power point tracking (MPPT) performanceand increase energy yield during transient state of MPPT process. This strategyis based on the estimation of short circuit current (SCC) of the photovoltaic(PV) system without short circuit. Besides that, this strategy aims to decreaseconvergence time to maximum power point (MPP) by preventing real short circuitof PV source and eliminating the additional switch requirement. To determineperformance of the proposed strategy, simulation studies have been performed inMATLAB/Simulink and this strategy has been compared with fractional SCC (FSCC)technique and perturb and observe (P&O) algorithm. In addition, to makevalidation experimentally, a low powered single ended primary inductanceconverter (SEPIC) is realized. Both simulation and experimental results showthat proposed strategy performs better transient MPPT performance than FSCCtechnique and P&O algorithm.
