Complementary scheduling rules for hybrid pumped storage hydropower

The PV output is not adjustable and therefore, coordinating the operation of the hydropower and pumping stations is imperative to ensure constant power output of the system and maximize system benefits. The pumping station should work at valley load hours when the electricity price is low, thus storing more water for future use.

OverviewPotential technologiesBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactHistory

Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW Rance tidal power station in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only larg
