A Critical Analysis of Flywheel Energy Storage Role in Grid Stability and Frequency Regulation

As India transitions to clean energy and aims to phase out fossil fuel usage by 2070, researchers and engineers are actively exploring alternatives for emissions-free energy generation and storage. While renewable resources currently provide viable options for energy extraction, their intermittent nature resulting in unpredictable availability and power production poses a significant challenge to grid stability. To address this issue, implementing energy storage systems within the grid is essential. These systems must be conventional, sustainable, and eco-friendly. Among the various grid-level energy storage systems available in the market and isolated grids such as batteries, pumped hydro, flywheels, and supercapacitors this paper highlights the importance of s. It examines their effectiveness in contributing to grid stability and frequency regulation, demonstrating their potential as a key component in a sustainable energy future
