Virtual Power Plants

Definition

Virtual power plants (VPPs) are a network of decentralized power-generating units, such as renewable energy sources, batteries, and flexible energy consumers, that are aggregated and controlled through advanced software. This technology optimizes energy production and consumption, enabling these units to operate as a single, reliable power plant. VPPs play a critical role in enhancing grid stability, integrating renewable resources, and promoting energy efficiency in the context of modern energy systems.
