Abstract

This paper introduces a novel methodology for the optimal sizing of multiple Battery Energy Storage Systems (BESS) in Hybrid Generation Systems (HGS) connected to the electrical grid. Focusing on centralized dispatch, which includes wind and photovoltaic generation along with BESS integration, the methodology employs Particle Swarm Optimization (PSO) to find optimal solutions. The impact on reliability is assessed based on dispatch expectations, generation limitations, and grid power flow, utilizing brazilian climatic data and load profiles from the Northeast system. Through simulations with the IEEE 14-bus system in two HGS configurations and locations, optimal BESS capacities were determined to be 36.25 MWh for one site and 24.25 MWh for the other. The results indicate a significant reduction in inflexibility by 17.41%, potential restriction by 17.17%, and fluctuations in slack bus imports by 20.46%.
