Abstract
Deterministic methods to evaluate unit commitment and spinning reserve requirements cannot explicitly recognise the stochastic nature of a p ower system. Probabilistic techniques can, however, be used to incorpo rate a wide range of stochastic system parameters. The usual technique s of probabilistic unit commitment in an interconnected system conside r the tie-line constraints but not the transmission facilities within the systems. In a real power system the transmission facilities within the systems have limits and do fail. Units committed from only probab ilistic generation studies, therefore, provide optimistic values. In t he paper, the usual techniques of unit commitment are extended to calc ulate a risk value from a composite system point of view. The effect o n the risk value of rapid start and hot reserve units are considered.
