PV System Analysis Under Partial Shading Using a Sine Model
Abstract
  A photovoltaic panel exhibits highly non-linear P-V & I-V characteristics, further, its Maximum Power Point Tracking (MPPT) operation becomes difficult during partial shading for high performance. During partial shading condition, the P-V array characteristics have more than one maxima point and the PV array panel models employed to locate for Global Maximum Power Point Tracking (GMPPT) analysis becomes complex. In this paper, the effects on PV system characteristics under possible shading conditions are analyzed. A 450 W, PV array system modeling is carried out for different shading conditions with sinusoidal functions. The problem is analyzed for PV panel connection to produce maximum power output. The results from the developed Sine model for the partial shading for GMPPT using Matlab/Simulink software platform is simulated. The effective GMPPT operation is done to validate the sine model.
