ABSTRACT
Nowadays, carbon dioxide emissions, energy security and decrease of fossil fuels are a top priority of the international agenda. Renewable energy sources are available in unlimited quantities and represent a viable alternative in economic terms. Fuel cells and photovoltaic panels (PV) are crucial to meet future energy needs while decarbonizing the power sector. This work aims to model an independent hybrid energy system based on renewable energies (RES) consisting of photovoltaic panels (PV) and PEM fuel cell stack. The objective of the work was to model a sustainable and reliable power source for a residential building, by using a hybrid energy storage system based on batteries for short-terms and hydrogen for longer periods. The sizing, performance and costs parameters for a proposed model were analysed based on models from literature. A 23kWh/d with a 2,6 kW peak power demand is considered for our application. The battery states of charge represent the constrained parameter which varies between 40% and 90% limits. HOMER environment software is uses to simulate the application. The independent hybrid energy system RES consists of photovoltaic panels (PV), PEM fuel cells, hydrogen tank, electrolyzer, battery and converter.
