Power balance in an electricity transmission system is one of services that an electricity transmission system operator has to guarantee. This means that power export or import to or from surrounding interconnected electricity transmission systems should be kept at given values. A power balance deviation in the electricity transmission system behaves as a stochastic process. Consequently, the aim of control strategy of such a quantity is to keep its amplitudes within specified boundaries centreed around zero. The electricity transmission system operator uses ancillary services for the control. The question is whether power reserves of the services are sufficient for reliable operation of the electricity transmission system. A Monte Carlo simulator has been developed for such a purpose. The simulator models behaviour of the system under constraints given by the power reserves of the services.
