Item Open Access Security-Constrained Optimal Scheduling of Transmission Outages with Load Curtailment from a Transmission Facility Owner’s Perspective(2017) Liu, Yuan; Zareipour, Hamidreza; Motamedi, Amir; Knight, Andrew; Westwick, DavidTransmission outage scheduling from a transmission facility owner’s (TFO’s) perspective in a de-regulated electricity market is one of the lesser-explored topics in academia. Much of existing literature focuses on generation maintenance scheduling with added transmission constraints from an independent system operator’s point-of-view; however, transmission outage scheduling by itself has not been touched on. This thesis presents a security-constrained transmission outage scheduling model that can be used by any TFO with limited access to system operation information. The proposed mixed-integer linear programming (MILP) model allows multiple outages on a single asset to be scheduled. It also incorporates a new load shedding methodology that allows transmission branches to radially connected and in-and-out connected buses to be taken out-of-service under outage and contingency conditions, which further improves its versatility. The proposed model is tested on two networks, (1) a simple four-bus system and (2) the 62-bus AltaLink 500kV/240kV backbone system in Alberta, Canada.
