Photovoltaic array exhibits highly nonlinear electrical characteristics and the maximum power point tracking (MPPT) is always challenging. It becomes more complex during partial shading condition. The P-V array characteristics for shading condition have multiple maxima points and conventional MPPT technique fails to track global maximum power point. The operating point may settle at local point...
