A procedure for the computation of the spot price component associated to transient instability.

Abstract

The present trend towards power system deregularitation has brought the need to accurately compute the costs associated with the different services provided by the electric utilities. Among these costs is the cost related to maintain an adequate level of security face to the contingencies which the power system may suffer, and specifically face to the possibility of loss of synchronism because of transient instability. This paper shows that this computation is feasible in the framework of marginal pricing theory. In fact, a procedure to compute the value of the component of the spot price associated to the transient instability is shown, as well as a numerical example in the well-know 31-buses New England network.
