Explorando a integração de baterias em sistemas fotovoltaicos: Uma perspectiva analítica.

Abstract

The use of batteries combined with photovoltaic generation systems allows consumers and businesses to make more advantageous choices and protect themselves against high electricity bills. Recognition of the importance of integrating Renewable Energy Sources and Energy Storage Systems (ESS) into electrical systems has been steadily growing in recent years. Due to the intermittent nature of renewable energy sources, such as wind and solar, the feasibility of their large-scale integration depends considerably on energy storage. From an energy efficiency standpoint, it would also be highly advantageous, as the system would be using stored energy to meet peak demand times, rather than relying exclusively on the generation system. This would allow the generated energy to be directed towards other purposes, resulting in savings for the system as a whole. The central purpose of this study is to assess the technical feasibility of implementing an Energy Storage System (ESS), referred to as BESS (Battery Energy Storage System), supplied by a solar photovoltaic generation system. The objective is to discharge the batteries' energy into the grid during peak hours, reducing contracted demand during this period by two-thirds. This approach is justified by the fact that many medium-sized consumers face high costs during peak energy demand periods.
