Concluding remarks An extensive review of pumped hydroelectric energy storage (PHES) systems is conducted, focusing on the existing technologies, practices, operation and maintenance, pros and cons, environmental aspects, and economics of using PHES systems to store energy produced by wind and solar photovoltaic power plants.
What is pumped hydro storage?
Pumped hydro storage is a well-tested, mature technology capable of releasing large, sustained amounts of energy through water pumping. The process requires two reservoirs of water, one at a low elevation, and the other at a higher elevation. Once connected, low cost electricity (like solar) is used to pump the water from below to above.
How do photovoltaic pumped hydroelectric energy storage systems work?
The water from the upper reservoir is released through hydraulic turbines to produce energy during peak load hours. This sub-section presents the review of existing, if any, and the theoretical studies reported in the literature on photovoltaic based pumped hydroelectric energy storage systems.
