Design and simulation of 20MW photovoltaic power plant using PVSyst

Abstract

This paper deeply explains the analysis through simulation and sizing of grid connected photovoltaic plant of 20MW for the site Devdurga, Karnataka India with use of PV syst software tool. Primarily, the trajectories obtained from the software describes performance of PV configuration at a particular location. It gives results for the geographical position taken by maps for sizing of the components which projects the installation with very much realistic conditions. The projected area is of about 110 acres would generate 44854 MWh/year for a 20MW PV configuration, with a performance ratio of 76.28%.Loss fraction taken for simulation and sizing is 2%. The paper also includes the study and behavior of the system with tilt and orientation of the PV Panel which gives better simulation results at similar latitudes for any feasible sizing.
