Introduction of Electricity Storage and Photovoltaics for an Adequate Self-Sufficiency in Large Building Complexes

Abstract

Energy usage in large-scale premises exhibits a distinctive pattern, encompassing both thermal energy and electricity. As a result of the recent energy crisis, the operational expenditures associated with these demands have markedly risen. In line with EU Energy Policies, one of the future goals is the transition towards energy-wise self-sufficient buildings powered by renewable energy sources (RES). Nowadays, a combination of contemporary energy management systems, electricity storage and RES are proposed to achieve nearly zero emission-producing energy consumption in buildings. This paper examines the energy consumption patterns of a hotel situated on the Mediterranean, in order to investigate the potential of RES-induced independence and forecast future expansion prospects. An algorithm has been introduced to both optimize and enhance the self-sufficiency of the hotel under consideration. The proposed algorithm successfully enhances the hotel's energy self-sufficiency, achieving a remarkable 99% rate through the dimensions of PV power and corresponding battery capacity for all years under examination, yielding the corresponding financial and environmental conclusions.
