Abstract
This work proposes a Grid-Connected Photovoltaic Generation System (PV-GCGS) with a new and simple Maximum Power Point Tracking (MPPT). The system is composed of two stages: the short circuit current sensor stage and the dc-ac conversion stage that is a three phase Voltage Source Inverter (VSI) with space vector modulation (SVPWM) technique. The adopted MPPT technique calculates the phase angle between the inverter voltage and grid voltage to determine the optimal slope of the power load line which corresponds to the Maximum Power Point (MPP) of PV generator. The whole components of the adopted PV-GCGS (Cdc conductance, Lf leakage inductance of transformer, transformer ratio and SVPWM characteristics) are designed to meet the constraints of performance and grid integration. A closed-loop controller is proposed to regulate the inverter voltage amplitude to be equal to the grid voltage in order to minimize the reactive power consumed by the transformer leakage reactance. The results are validated by simulation in the Matlab-Simulink environment.
