In order to sustain a continuous supply of electric power during a potential N-1 event, sufficient amount of reserves have to be acquired. The acquisition of such contingency reserves starts at the day-ahead scheduling phase. However, modern day-ahead unit commitment problems, which acquire reserves that exceed the largest contingency, do not guarantee a reliable solution as the deliverability of the reserves depends on the reserve locations. Corrective transmission topology control can be used by the operator during a post-contingency state as a mechanism to improve the deliverability of reserves. In this paper, a model that incorporates corrective transmission topology control within contingency analysis is presented. Various solution techniques are also compared in terms of performance and these methods are tested on the IEEE 118-bus and IEEE 73-bus test systems. Numerical results show that topology control significantly reduces the number of cases with constraint violations.
