Optimizing the profit from a complex cascade of hydroelectric stations with reci...
Korobeinikov, Andrei; Kovacec, Alexander; McGuinness, Mark; Pascoal, Marta; Pereira, Ana; Vilela, SóniaIn modern reversible hydroelectric power stations it is possible to reverse the turbine and pump water up from a downstream reservoir to an upstream one. This allows the use of the same volume of water repeatedly and was specifically developed for hydro-electric stations operating with insufficient water supply. Pumping water upstream is usually done at times of low demand for electricity, to build up reserves in ...
