The present invention relates to a gas storage power station () having a turbine group () and a compressor group (). The turbine group () has at least one turbine () and a generator (). During normal operation of the turbine group (), the generator () emits power directly to a main load (). The compressor group () has at least one compressor () and one electric motor (). The gas storage power station () furthermore has a power consumption device (), which can be activated in order to consume turbine and/or generator power.

The invention provides a method of operating a gas turbine arranged in a power generation system and comprising a source of compressed air, a combustor having a combustion chamber and multiple burners. A gas turbine controller controls the activation and deactivation of the single burners and/or burner groups according to a switching criterion that is proportional to the difference between a combustion chamber air inlet temperature and a temperature downstream of the combustion chamber. The switching criterion according to the invention fully accounts for large temperature fluctuations of the combustion chamber inlet air, which then result in only relatively small variations in burner equivalence ratio. The invention is particularly suited for application in compressed air energy power generation plants.
