Optimal sizing of PV system and energy management in Buildings

The Photovoltaic is the future´s solution for the electrical energy production. This is why; it deserves to be a little more exploited than now. It is an energy which allows an autonomous production of electricity, an economy of fossil fuels and thus the reduction of gas emissions as well as the reduction of the atmospheric pollution. Building is considered as encouraging potential of energy saving and a lot of researches have been developed in this topic. This paper focuses on Energy Management System for the optimal sizing of sources and for the optimal plan of energy in Mechanics Engineering Department Building at Skikda University. Determining the optimal area of a PV installation, the optimal battery installation size, and the minimum power to be contracted with the electricity provider are developed. This optimal sizing allows obtaining the return of the investment costs of the installation and gains from selling the exceeding electricity, which is locally produced.
