Impact of Energy Storage Technologies on Grid-Connected Renewable Energy Systems

Abstract

The inclusion of renewable energy into the grid causes issues thanks to the intermittent features of sources such as solar and wind. Energy storage technologies are crucial for grid reliability and efficiency. This study explores how batteries, pumped hydro, and flywheels affect grid-connected renewable energy systems. A thorough investigation is made on how energy storage mitigates difficulties such as voltage regulation, frequency control, and load balancing. Economics, environment, cost-benefit analysis, and sustainability are also considered. The analysis underlines the capacity of energy storage to ease the intermittency of renewable energy, while also emphasizing the technical, regulatory, and market constraints that must be solved for extensive deployment. The results imply that improvements in storage technologies are vital for reaching a more resilient, stable, and sustainable system driven by renewable energy.
