This uncertainty has ignited a renewed interest in Pumped Hydroelectric Energy Storage plants. Pumped storage systems today are considered one of the most effective methods to overcome the regular water variability problem. In this report, the introduction of pump storage facilities is investigated along with its technical and economic feasibility.
The pumped hydro energy storage system (PHS) is based on pumping water from one reservoir to another at a higher elevation, often during off-peak and other low electricity demand periods. When electricity is needed, water is released from the upper reservoir through a hydroelectric turbine and collected in the lower reservoir .
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. Fig. 7. A conceptual solar photovoltaic based PHES.
Fundamentals of pumped hydro storage The energy used in a pumping station is the potential, so it is the mass of the water and its difference in height that determines the stored energy, and the flow of the turbines the power obtained, remembering that power is rate of energy per time.
