Design, Digital Control, and Simulation of a Grid-Connected Photovoltaic Generation System

This paper presents simulation and digital control of a three-phase grid-connected photovoltaic (PV) generation system. The technique used for maximum power point tracking (MPPT) of photovoltaic power is sliding mode (SM) control. Control of power extraction from DC link capacitor is presented. Space vector pulse width modulation (SVPWM) inverter is utilized to deliver power to utility grid. Simulation is performed using PLECS standalone software package and simulation results are shown. Complete theoretical foundation needed for system simulation is presented.

Keywords:

sliding mode control; solar energy; space vector pulse width modulation,
