A Space Reduction Heuristic for Thermal Unit Commitment Considering Ramp Constraints and Large-Scale Generation Systems

This paper expands the research around a recently proposed method to reduce search space region for thermal unit commitment problems. The importance of such techniques comes from combinatorial explosion regarding variables problem when there are large quantity generating units in system. heuristic approach utilizes sensitivity indices gather information about system and fix many binary decision over planning horizon. work further explores by demonstrating its effectiveness large-scale systems subjected ramp constraints. Despite significantly increased complexity, results this indicate that can achieve high quality solutions notably faster than other approaches literature.
