In electricity markets, independent system operators solve the unit commitment (UC) problem to determine the on/off status of generating units with respect to the day-ahead load forecast. However, as the size of power systems grows, computational complexity of the UC problem drastically increases. In this paper, based on the greedy adaptive search procedure (GRASP) technique, we propose a novel heuristic...
Power system operators commonly rely on a security-constrained unit commitment (SCUC) to schedule available generation resources for satisfying the forecasted load and ensuring system security in response to limited components unavailability. Although widely used and proved viable, the SCUC problem cannot guarantee a useful solution in response to extreme events with potentially multiple outages....
