An Overview of Application of Optimization Models Under Uncertainty to the Unit Commitment Problem

Abstract: Optimization models have been broadly used within side the energy industry as useful decision-making systems for scheduling and dispatching electric powered energy resources; this is applied in a system called unit commitment (UC). Unit Commitment seeks the maximum price adequate generator commitment scheme for an electric powered energy device to satisfy a certain demand, at the same time as fulfilling the operational constraints on transmission models and computational resources. Taking into account risk variability in those processes and checking out their comparative overall performance for a single or multi-stage energy model as a function of monetary performance in addition to the risk related to the commitment decisions. Stochastic programming and Robust optimization are by a vast majority the most widely studied methodologies for UC under net load uncertainty. These techniques will be discussed in this paper.
