An MISOCP-Based Decomposition Approach for the Unit Commitment Problem with AC Power Flows
IEEE Transactions on Power Systems, 2022 Unit Commitment (UC) and Optimal Power Flow (OPF) are two fundamental problems in short-term electric power systems planning that are traditionally solved sequentially. The state-of-the-art mostly uses a direct current flow approximation of the power flow equations in the UC-level and the generator commitments obtained are sent as input to the OPF ...
