Design and analysis of a rooftop PV system for a University Building in Pakistan

Abstract

In this paper, the hourly load profile of a university building in Pakistan based on electricity bills is presented. Using the load profile, a rooftop PV system has been designed. Homer Pro software has been used for steady-state modeling and analysis of the system. The designed system comprises of 126kW PV, including 200, 12V, 205 Ah batteries and a 43kW inverter. Analysis shows that the designed system can fulfill all electricity requirements of the building. The dynamic simulation and analysis are carried out using MATLAB/Simulink. For maximum power output of PV, a perturbation and observation-based algorithm with a DC-DC boost converter have been selected for the system. Results show the designed system can provide stable voltage and frequency for a full load of that university academic building.
