This paper addresses the unit commitment problem, where a system operator decides the on-off status and the amount of generation of each generator for each time period during a given planning horizon to meet the electricity demand at minimum cost. Especially, to deal with uncertain demand, we consider the stochastic unit commitment problem, where the expected cost is minimized under the pre-determined set of scenarios. To mitigate the increasing computational burden of the problem as the number of scenarios increases, we propose a unit decomposition approach to solve the problem. It is a specialized Lagrangian relaxation-based solution approach that relaxes coupling constraints among generators and thus decomposes the remaining problem into single-unit commitment problems. We also propose an efficient dynamic programming algorithm for the subproblem to enhance the proposed solution approach. Through the numerical experiments, we show the efficiency of the proposed dynamic programming algorithm for the subproblem. In addition, we demonstrate the efficiency of the proposed unit decomposition approach for the stochastic unit commitment problem.
