Grid services refer to the various functions and capabilities provided by electrical grids to ensure reliable and efficient power distribution. These services include balancing supply and demand, maintaining voltage levels, and providing backup power during outages. They help integrate renewable energy sources like solar power and wind energy into the grid, enhancing overall energy sustainability. Additionally, grid services support the management of energy storage systems, allowing for better utilization of resources. They also facilitate demand response programs, where consumers adjust their energy usage based on grid needs. This coordination helps optimize the performance of the entire electricity grid.
