How Pumped Storage Hydro Works. Pumped storage hydro (PSH) involves two reservoirs at different elevations. During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the higher reservoir. When electricity demand increases, the stored water is released, generating electricity.
Renewable energy utilization for electric power generation has attracted global interest in recent times [1], [2], [3]. However, due to the intermittent nature of most mature renewable energy sources such as wind and solar, energy storage has become an important component of any sustainable and reliable renewable energy deployment.
