Research on eigenparameters and detection methods for single‐phase‐to‐ground faults in non‐effectively grounded distribution systems

open access: yesIET Cyber-Physical Systems, 2023
Non‐effectively grounded power distribution systems (NGDS) are widely used in China and other countries. However, over a long time, single‐phase‐to‐ground faults (SGF) have been misjudged or omitted by the monitoring system, threatening the security of ...

On the Conic Convex Approximation to Locate and Size Fixed-Step Capacitor Banks in Distribution Networks

open access: yesComputation, 2022
The problem of the optimal siting and sizing of fixed-step capacitor banks is studied in this research from the standpoint of convex optimization. This problem is formulated through a mixed-integer nonlinear programming (MINLP) model, in which its binary/

Application of neutrosophic minimum spanning tree in electrical power distribution network

open access: yesCAAI Transactions on Intelligence Technology, 2020
The problem of finding the minimum spanning tree (MST) is one of the most studied and important combinatorial optimisation problems in graph theory. Several types of uncertainties exist in real-life problems, which make it very hard to find the exact ...
