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 ...

Differential Privacy of Aggregated DC Optimal Power Flow Data [PDF]
, 2019 We consider the problem of privately releasing aggregated network statistics obtained from solving a DC optimal power flow (OPF) problem. It is shown that the mechanism that determines the noise distribution parameters are linked to the topology of the ...

Optimal Power Flow Control by Rotary Power Flow Controller
Advances in Electrical and Computer Engineering, 2011 This paper presents a new power flow model for rotary power flow controller (RPFC). RPFC injects a series voltage into the transmission line and provides series compensation and phase shifting simultaneously.

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

Convex Relaxation of Optimal Power Flow, Part II: Exactness [PDF]
, 2014 This tutorial summarizes recent advances in the convex relaxation of the optimal power flow (OPF) problem, focusing on structural properties rather than algorithms. Part I presents two power flow models, formulates OPF and their relaxations in each model,
