1. Pumped hydropower, an energy storage technology.
2. It is about using water as a means of energy storage to realize the storage and management of electrical energy through the mutual conversion of electrical energy and potential energy. Electrical energy during the low power charging period is used to pump water to the upper reservoir, and then the water is released to the lower tank to generate electricity during the maximum power charging period.
3. It can convert excess electrical energy when the grid load is low into high-value electrical energy during peak grid periods.
