Abstract: In modern power systems, flexibility is vital for adapting to fluctuations in energy demand and supply, ensuring stability amid the increased integration of renewable sources. However, renewable energy’s inherent instability and low system inertia pose challenges, as weather-dependent generation and lack of peak demand matching complicate grid integration. Unlike traditional power plants, renewables lack substantial flywheels for inertia, exacerbating frequency instability risks. The rise of renewables diminishes reliance on large-scale generators, heightening grid vulnerability. Decentralization and distributed energy resources further reduce system inertia, intensifying stability concerns. Overcoming low inertia involves strategies like integrating energy storage and regulating wind turbine output. Strategic power system scheduling and ancillary services are crucial for stability amid evolving energy paradigms.
