Solving Certain Type of Large-Scale Scheduling Problems via Hybrid Decomposition

Antonio Conejo and his research team proposes an efficient solution method for the stochastic unit commitment problem with weekly dispatched energy storage, an important large-scale scheduling problem. Using Benders’ framework, the proposed solution method decomposes the problem into a mixed-integer linear master problem, and linear and continuous subproblems. The master problem corresponds to the first-stage decisions and includes all the commitment variables and their corresponding constraints. The subproblems correspond to the actual dispatch of the generating units and their deployment of generation reserves. Based on the success of column-and-constraint generation algorithms to solve robust optimization problems, the team improves the low communication between the master problem and the subproblems to the master problem, which provides a better approximation of the recourse function. Their computational experiments demonstrate the effectiveness of the proposed decomposition method using an instance of the South Carolina 500-bus system under 40 scenarios.
