Abstract :
One of basic system services that an electricity transmission system operator guarantees is power balance maintenance. The aim of this service is to keep power export/import to/from surrounding interconnected electricity systems at a proposed value. This implies that the amplitude of a power balance deviation has to be kept in specified boundaries. The operator uses so called ancillary services for this purpose. In order to perform the overall volume and structure optimization of the ancillary services it is needed to know the magnitude and dynamics of the deviation that will be decayed. For this reason a deviation balance model has been designed and is presented in the paper. It describes electricity transmission system operation
