Reconfigured Photovoltaic Model to Facilitate Maximum Power Point Tracking for Micro and Nano-Grid Systems

PV systems are a popular energy resource, prevalent worldwide; however, shade faults manifested in limit its power conversion efficiency. The occurrence of multiple peaks and their location highly uncertain systems; this necessitates the use complex maximum point tracking algorithms to introduce high voltage oscillations. To address issue, new reconfigurable array produce global (GMPP) algorithm close Voc regions was introduced. This enables simple Perturb Observe (P&O) easily track GMPP. For reconfiguration, 5 × is considered, physical relocation procedure based on position square method proposed. Performance proposed reconfiguration model tested for four various events row current evaluations comprehensively analyzed. Furthermore, fill factor, mismatch loss, loss quantitatively compared against Dominance Square TCT schemes. Since enhancement ensured array, fixed tailored suit residential microgrid systems. MPP evaluations, hardware demonstrations performed with lab scale prototype developed simulator DC–DC electronic interface. I–V characteristics conventional reconfigured models programmed into hill climbing validated. analyze oscillations tracking, PSO also two test patterns results studied.
