Design and Simulation of 500kW Grid-connected PV System For Faculty Of Engineering, Rivers State University Using Pvsyst software
Abstract
This work is based on the design and simulation of a proposed 500kW grid connected PV system using Pvsyst which is desired to take care of 995,161 MWh annual load demand of the Faculty of Engineering, Rivers State University (FOERSU) between the official hours of 8am to 4pm daily using Pvsyst7.2.6 programming software and the excess energy is sold to the Power Holding Company of Nigeria (PHCN) through the grid network. The University community has a mean solar radiation of 4.55kWh/m2/day as obtained from Nigerian Meteorological Agency (NIMET) and an average temperature of 26.610C. The method used is enumeration of electrical load of the Faculty of Engineering alongside their hour of operation to obtain the energy required per day in Watt hour (1523.768kWh) but 2726.48kWh is used for the purpose of selling the excess and also due to load forecast. The energy (2726.48kWh) is divided by an average sun hour of 4.5 hours and the result is again divided by a threshold frequency of 0.77 to get the peak power of the PV module (787kWp). This peak power, tilt angle of 50, grid voltage (415V) are entered into the Pvsyst programming software to chose the number of PV panels in series and parallel and the inverter. The simulation result shows that the annual DC energy the proposed plant generates per year is 1,140,796kWh while the actual AC energy exported to the grid network is 1,114,502kWh/year with a loss of approximately 20%. The effects of weather conditions on the overall performance were looked at. The proposed PV plant is viable and will address the lingering energy crisis in the faculty. A total of 1962 panels are required for this work with 18 panels in series and 109 panels in parallel. Multilevel inverter is used to track the maximum power from the PV array.
