Abstract
A storage power station (S), for example an air storage plant, that includes a compressor unit (V), a turbine unit (T) and a storage volume (100) can be operated using a specific method of operation, which allows as fast a reaction as possible to changes in the load demands. Rapid changes in the load demands can be satisfied by controlling the power consumption of the compressor unit (V), which results in a variable net power output, with the power output from the turbine unit (T) remaining constant. The power of the compressor unit can be controlled approximately one order of magnitude more quickly than the power generation machine can be controlled. In the extreme, the compressor unit can simply be shut down, thus resulting in its drive power becoming available to an electricity grid within seconds. During this process, the turbine unit can continue to operate normally, and can slowly follow the power demand, thus reducing the load on the turbine. A storage power station can thus be ideally suitable for frequency support and for covering rapid load ramps in an electricity grid.
