Evaluation of the marginal outage costs in composite generation and transmission systems

Abstract

Evaluation of the marginal outage costs in generation systems using quantitative power system reliability techniques has been recently demonstrated. It was shown that the marginal outage cost varies with the operating reserve and the lead time into the future. This paper is concerned with the variation of the marginal outage costs over space because the location of loads with respect to the overall system topology containing both generation and transmission facilities has an impact on these costs. The effects of selected pertinent factors on the marginal outage cost in composite systems are also presented. The proposed method and sensitivity studies are illustrated using the IEEE Reliability Test System.
