Abstract

This paper proposes a novel maximum power point tracking (MPPT) algorithm based on analyzing the output characteristics of PV array under uniform irradiance and partial shading conditions (PSC). The algorithm adds partial shadow judging conditions in variable step perturb and observes (P&O) method. The system runs the variable step P&O method to realize MPPT when photovoltaic array is under uniform irradiance. Under PSC, the control method can eliminate the interference of local maximum power point (MPP) to make the PV array running at global MPP. Experimental results verify that the proposed algorithm can automatically track the global MPP under uniform irradiance and PSC.
