Distributed optimal power flow. [PDF]

PLoS ONE, 2021
ObjectiveThe objectives of this paper are to 1) construct a new network model compatible with distributed computation, 2) construct the full optimal power flow (OPF) in a distributed fashion so that an effective, non-inferior solution can be found, and 3)

Optimal Power Flow with Power Flow Routers [PDF]

IEEE Transactions on Power Systems, 2017
Power flow routing is an emerging control paradigm for the dynamic control of electric power flows. In this paper, we propose a generic model of a power flow router (PFR) and incorporate it into the optimal power flow (OPF) problem.

Linear Optimal Power Flow Using Cycle Flows [PDF]

Electric Power Systems Research, 2018
Linear optimal power flow (LOPF) algorithms use a linearization of the alternating current (AC) load flow equations to optimize generator dispatch in a network subject to the loading constraints of the network branches.

Graphical Models for Optimal Power Flow [PDF]

Constraints, 2016
Optimal power flow (OPF) is the central optimization problem in electric power grids. Although solved routinely in the course of power grid operations, it is known to be strongly NP-hard in general, and weakly NP-hard over tree networks.

Equivalent relaxations of optimal power flow [PDF]

IEEE Transactions on Automatic Control, 2014
Several convex relaxations of the optimal power flow (OPF) problem have recently been developed using both bus injection models and branch flow models.

AC&DC optimal power flow incorporating centralized/decentralized multi-region grid control employing the whale algorithm

Ain Shams Engineering Journal, 2021
In this paper, different optimization algorithms are introduced to solve the security-constrained optimal power flow between two connected regions, applying two control modes, namely the centralized and decentralized modes.

Optimal power flow with small signal stability constraints [PDF]

Científica, 2022
A power system presents different stability problems, the small-signal stability problem receives attention to the occasional oscillations and the change in its demand, for this and the need to optimize resources a smallsignal stability constraint is ...

Optimal Configuration Method for DC Power Flow Controller Considering Power Flow Transfer Characteristics

Zhongguo dianli, 2021
The number of DC power flow controllable lines follows the N−1 principle. Installing DC power flow controller (DCPFC) on the line can improve the controllability of line power flow.
