What is pumped storage hydropower?
Pumped storage hydropower is a type of hydroelectric power generation that plays a significant role in both energy storage and generation. At its core, you've got two reservoirs, one up high, one down low. When electricity demand is low, excess energy from the grid is used to pump water from the lower to the upper reservoir.
How does a hydro storage system work?
The system utilizes a photovoltaic panel as the main energy source and a battery pack as the energy storage device to smooth the fluctuation of solar power and to mitigate load transients and variations. In addition, a hydro storage system is used for water storage and also for supplying extra electric power via a hydro-turbine generator.
