Numerical Comparison Between GSC and P&O Controller for MPPT Applications

This work proposes a Gain Scheduling Control to guarantee the maximum power transfer in a photovoltaic system even if variations in the solar resource are presented. This strategy improves the step response characteristics of maximum power each instant. A case study of a solar generator with SEPIC converter is simulated and evaluated in comparison with P&O strategy. Results show that the proposed strategy control provide an improved response with the expected reduction of settling time and ripple in output power.
