Generalized linear‐constrained optimal power flow for distribution networks
IET Generation, Transmission & Distribution, 2023 Optimal power flow (OPF) plays an important role in the secure and economical operation of the distribution network. This paper proposes a novel generalized linear‐constrained optimal power flow (GLOPF) model for both radial and mesh distribution ...

An Extended DC Power Flow Model Considering Voltage Magnitude
Journal of Modern Power Systems and Clean Energy, 2021 A quasi-linear relationship between voltage angles and voltage magnitudes in power flow calculation is presented. An accurate estimation of voltage magnitudes can be provided by the quasi-linear relationship when voltage angles are derived by classical ...

A Linear-Programming Approximation of AC Power Flows [PDF]
INFORMS Journal on Computing, 2014 Linear active-power-only power flow approximations are pervasive in the planning and control of power systems. However, AC power systems are governed by a system of nonlinear nonconvex power flow equations. Existing linear approximations fail to capture key power flow variables, including reactive power and voltage magnitudes, both of which are ...

On the minimal set of controllers and sensors for linear power flow [PDF]
Electric power systems research, 2020 We consider a linear power flow model with interval-bounded nodal power injections and limited line power flows. We determine the minimal number of power injections to control based on a minimal set of measurements, such that the overall system is ...

Optimization-Based Islanding of Power Networks Using Piecewise Linear AC Power Flow [PDF]
IEEE Transactions on Power Systems, 2014 In this paper, a flexible optimization-based framework for intentional islanding is presented. The decision is made of which transmission lines to switch in order to split the network while minimizing disruption, the amount of load shed, or grouping coherent generators.
