A Linear Programming Method Based Optimal Power Flow Problem for Iraqi Extra High Voltage Grid (EHV)

open access: yesJournal of Engineering, 2023
The objective of an Optimal Power Flow (OPF) algorithm is to find steady state operation point which minimizes generation cost, loss etc. while maintaining an acceptable system performance in terms of limits on generators real and reactive powers, line ...

On the minimal set of controllers and sensors for linear power flow

open access: yesElectric Power Systems Research, 2021
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 feasible for all assignments of the non-controlled power injections.

Power Flow Efficiency of Linear and Nonlinear Physical Systems [PDF]

open access: yes2019 18th European Control Conference (ECC), 2019
In this paper, an analytical procedure to derive the efficiency of linear and nonlinear physical systems is presented. This procedure allows to compute the efficiency map both on the plane of the input power variables and on the plane of the output power variables. Additionally, the paper highlights the parameters to be adjusted in order to enlarge the

Ensemble Learning based Linear Power Flow [PDF]

open access: yes2020 IEEE Power & Energy Society General Meeting (PESGM), 2020
This paper develops an ensemble learning-based linearization approach for power flow with reactive power modeled, where the polynomial regression (PR) is first used as a basic learner to capture the linear relationships between the bus voltages as the independent variables and the active or reactive power as the dependent variable in rectangular ...

Ensemble learning based linear power flow

open access: yesCoRR, 2019
This paper develops an ensemble learning-based linearization approach for power flow, which differs from the network-parameter based direct current (DC) power flow or other extended versions of linearization. As a novel data-driven linearization through data mining, it firstly applies the polynomial regression (PR) as a basic learner to capture the ...

An online decision-making method for the overload preventive control of transmission equipment based on the control objects relaxation

open access: yes电力工程技术, 2023
The preventive control strategy can be solved quickly and effectively through the linear programming model based on active power sensitivity. However, the active power sensitivity obtained by the DC power flow method ignores the influence of voltage and ...
