Abstract
On scrutinizing P vs. V curves of P_V arrays which receives non_uniform insolation of light or simply during Uneven_Lighting_Conditions (ULCs) multiple LMPPTs are exhibited. Conventional MPPT methods are efficient in normal conditions even though they failed to identify the GMPPTs from LMPPTs under ULCs. To improve productivity of Maximum_PPT method for P_V arrays under both ULCs and normal conditions some modifications are tried in this study. The Incremental_resistance_method added with some alterations enables to track the LMPPTs as well as GMPPTs very effectively and accurately with less numbers of steps. In proposed system, losses during GMPP tracking is minimized under ULCs. Simulation is performed in MAT_LAB.
