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 ...

A General Formulation for Evaluating the Performance of Linear Power Flow Models

open access: yesCoRR, 2021
Linear power flow (LPF) models are essential in power system analysis. Various LPF models are proposed, but some crucial questions are still remained: what is the performance bound (e.g., the error bound) of LPF models, how to know a branch is applicable for LPF models or not, and what is the best LPF model.
