Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

The key finding of this study is that the incentive to build capital-intensive pumped hydro storage to firm wind power is limited unless exogenous market costs come very strongly into play. Furthermore it was demonstrated that reserve increases with increasing wind power showing the importance of ancillary services in future power systems.

Similarly, micro-pumped storage (MPS) system may be the ideal choice where traditional large-scale pumped storage is impractical due to cost and capacity issues [7, 8]. The pump is employed in this storage system, and runs in reverse mode (pump as turbine or PAT) under the generating operation condition [ 9, 10 ].

1 Introduction. Pumped storage hydropower (PSH) plants, also called "water battery", are storage energy systems consisting of two water reservoirs, a tunnel connecting these reservoirs and a powerhouse with turbines-pumps and motor-generators. It represents one of the most sustainable, economical, and efficient solutions for energy …
