450 pumped storage units installed worldwide by Voith. In 1937, Voith developed the first large, single-stage pump turbine, which operated both as a turbine for energy generation and in the reverse direction as a pump. Today, nearly 450 Voith pump turbines have been installed worldwide with a combined output of more than 60 000 megawatts.
3. Operation strategy. The operation strategy consists of three separate parts: (1) forecasting of wind velocity, (2) scheduling of the power exchange with the market and, (3) on-line operation of the storage. In the present model, the forecasts of load and spot price are assumed to have 100% accuracy.
In times of insufficient power supply or high energy costs, the water is released through turbines to produce electric energy. The efficiency of state-of-the-art systems is about 70-80%. The total head (geodetic height between upper and lower reservoirs) and the storage capacity of the reservoirs as given in a mountainous terrain, determine the energy …
