Renewable energy integration refers to the process of incorporating energy sources like solar, wind, and hydropower into the existing energy grid. This integration allows for a more sustainable energy supply by reducing reliance on fossil fuels and lowering greenhouse gas emissions. To achieve effective renewable energy integration, utilities and grid operators must manage the variability of these energy sources. This involves using advanced technologies, such as smart grids and energy storage systems, to balance supply and demand, ensuring a stable and reliable energy flow for consumers.
