Performance analysis of a Grid Connected Photovoltaic Power Plant with MPPT facility

This paper yields a simulation model of the electrical part of a grid connected photovoltaic system. The model contains a detailed representation of the main components of the system that are the solar array, boost converter, mppt controller, inverter control circuit and utility grid. A proper control of the DC/AC inverter is developed in order to synchronize the system to the grid. The grid interface inverter transfers the energy drawn from the photovoltaic (PV) array into the grid by keeping common DC coupling voltage constant. A simulation model has been developed with the help of mathematical equations and performance is analyzed under varying irradiance level. This paper can be useful for the PV power plant designers to analyze the output of the power plant by using the simulation model. This model is a simplified approach of the system’s individual modules.
