Resumen
Integration of Renewable Energy Sources (RES) with Battery Storage Systems (BSS) in electrical transition contributes for advancing toward a cleaner and more sustainable energy future.
This integration offers several environmental and electrical advantages, including greenhouse gas emission reduction by displacing fossil fuel-based generation, ensuring grid stability, minimizing energy losses, and improving integration of renewable energy.
RES such as solar and wind, show inherent variability due to weather fluctuations. Battery storage systems can be used to integrate these energy sources into the grid by storing surplus energy and releasing it as needed. This integration ensures a stable and reliable electricity supply, contributing to grid frequency and voltage balance. Moreover, for overall energy efficiency, RES can be locally stored and used, reducing the reliance on long-distance transmission and associated energy losses.
The aim of this work is to investigate the impact of integrating battery storage systems with renewable energy sources on electrical variables. The selected variables are voltage, current, and power.
MATLAB/Simulink was used to create a hybrid electrical system with solar and battery storage. After that, the solar system was exposed to different radiation to study the effect on the system’s outputs.
The results demonstrate that the use of BSS in conjunction with RES leads to smoother output grid variables compared to relying solely on RES. It provides more stability at the grid level. Li-ion battery is shown to be fast-acting, thereby offering the possibility of voltage and current regulation.
The effect of using a Li-ion battery on the generated voltage, current, and power under the change of radiation is demonstrated
