Reduction of Energy and Reserve Cost with Transmission Switching Action

This paper focuses on the development of a model for optimal transmission switching procurements within the operating reserve where energy and reserve are jointlydispatched. In this paper a stochastic mix-integer linear programming model is utilized. Transmission switching can provide economic benefits when compared with other control methods such as generation unit rescheduling or load shedding for management contingency.The main purpose of this paper is to determine a sufficient amount of spinning reserve for a power system that considers the probabilistic behavior of system’s components and transmission switching for reducing spinning reserve cost. Transmission switching considering in contingency fordetermined optimal spinning reserve and utilized for management contingencies. Furthermore, because of problem is large scale, in this paper proposed to using the benders decomposition algorithm for solving the probabilistic joint energy and spinning reserve market problem.
