REVIEW OF GRID CONNECTED PV ARRAY USING P&O MPPT ALGORITHM

The renewable energy is becoming more mainstream and accessible. This has been made possible due to an increase in environmental awareness coupled with the popular demand to cut back on the greenhouse emissions. We in this project propose a grid connected PV system. The aim of the project is to implement a complete distributed energy resource system (DER). The project will feature a PV module, which will be controlled and optimized by means of a maximum power point tracking (MPPT) algorithm. A boost converter along with a single phase grid tie inverter will be used to increase the output voltage and to convert it to AC. A phase locked loop circuit will be used to integrate the single phase inverter with the grid. A control methodology consisting of PI controllers is employed for operating the PV at the MPPT point by controlling the switching of the boost converter and also for the operation of the single phase inverter and its integration with the grid. The parameters of these controllers are tuned to give the best results. This will be followed by a detailed mathematical and engineering analysis for the simulated results. The validity of the proposed scheme will be verified by simulation using the PSIMsoftware
