Optimal size selection of combined diesel generator/fuel cell/photovoltaic system components using a multi‐objective strategy and sea lion optimization algorithm

Abstract

AbstractOne of the challenges of the production sector of the electricity industry at present is how to meet the needs of electricity consumption in the country by using and localizing new power plant units. The main purpose of the presented paper is to offer an optimum arrangement for a combined diesel generator/FC/PV system for an off‐grid supply of electricity in a community in Shache, China. A multi‐objective scheme of the combined system is suggested with consideration of the unpredictability in solar radiation, load, and operating reserve (OR). The multi‐objective optimization has been established to make the TNPC (total net present cost) and LPSP (probability of power supply loss) minimum. In this study, the decision variables are the number of diesel generators (DG), photovoltaic (PV) panels, fuel cells (FC), electrolyzers, and hydrogen tanks. To get more authentication, the impact of several criteria on the size issue has been analyzed. The incorporation of a hydrogen production system lowers the overall expense of the combined systems, according to the modeling results. Plus, the operational reserve has a greater effect on the Pareto front in comparison with solar energy and load uncertainty.
