Modeling and Control of a Grid-Connected PV Energy Conversion System
Authors: , ,
Abstract: This paper investigates the efficiency of the Photovoltaic (PV) array. The proposed model is based on a DC-DC boost converter and a three-phase grid connected DC-AC inverter. This structure is used to provide the flexibility of the system and the quality of the generated waves. In order to improve the efficiency of the Photovoltaic array, a Maximum Power Point Tracking (MPPT) is used to provide a good results if the converter is controlled with PID compensator. The control of the output voltage is provided by the Pulse Width Modulation (PWM) technique. The three-level Voltage Source Converter (VSC) regulates DC bus voltage and keeps unity power factor. The results are presented in this paper using Matlab/simulink, which validate the pracicability of the proposed system.
