Wind turbines work only when it is windy. So, where shall the power during slack periods come from?
That problem concerns every company that uses wind for power generation. Apart from the fact that one can not rely on wind only, it also refers to the problem of efficient energy storage. Since this is a complex issue, I will at first give a basic answer and then move on to a targeted response regarding the project. 1st One possibility to tackle the addressed problem is to link different energy sources like wind, solar, hydro, and geothermal power into network. At the same time, energy can be stored by the use of reservoir power stations. Thereby, temporarily spare electricity is used to pump up water into a higher located reservoir. Once the power demand exceeds the supply the elevation potential of the water is utilized by using it’s down flow for the operation of generators. Since strong winds can cause damages to the grid by raising over-capacities, such reservoir stations also have an important protective function in relation to wind turbines. Because the storage of electricity on
