Sensitivity analysis of an optimal PV-DG-BES for sustainable power system of a technical institution in Niger State

Abstract

In this study, the different reactions of an ideal hybrid renewable energy system (HRES) to variations in the system input parameters of solar radiation was examined. HOMER software was used to conduct sensitivity analysis of the optimum system of the system under study. To allow for a broader examination, these parameters were changed by ±40%. The research work used sensitivity analysis to examine the impact of varying the hybrid system's input parameters on energy cost (COE), net present cost (NPC) and operational cost. The sensitivity analysis of the variation of solar radiation presented shows that as the solar radiation increases, there is a decrease in the NPC of the system and also a decrease in the levelized cost of energy of the hybrid system, although there is variation in the operating cost. The research work will serve as a means of sustainable energy development to be replicated in other region with similar solar radiation value of climatic condition in promoting energy access.
