Equivalent Relaxations of Optimal Power Flow [PDF]
IEEE Transactions on Automatic Control, 2015 Several convex relaxations of the optimal power flow (OPF) problem have recently been developed using both bus injection models and branch flow models. In this paper, we prove relations among three convex relaxations: a semidefinite relaxation that computes a full matrix, a chordal relaxation based on a chordal extension of the network graph, and a ...

Power-flow-tracing-based congestion management in hydrothermal optimal power flow algorithm
Journal of Modern Power Systems and Clean Energy, 2019 This paper presents a method for managing congestion constraints in a hydro-thermal optimal power flow solution procedure. The congestion constraint is handled in this paper as an active power generation constraint. To achieve this solution, a power flow

Health-Focused Optimal Power Flow [PDF]
2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2021 In this paper, we propose a novel Health-Focused Optimal Power Flow (HF-OPF) to take into account the equipment health in operational and physical constraints. The health condition index is estimated based on the possible fault characteristics for generators and batteries.
