A conceptually simple algorithm for the capacitated location-routing problem

open access: yesEURO Journal on Computational Optimization, 2023
Location-routing problems (LRPs) jointly optimize the location of depots and the routing of vehicles. The most studied LRP variant, the capacitated LRP (CLRP), has been addressed by a large number of metaheuristic approaches.

Modeling simulation and inverter control strategy research of microgrid in grid-connected and island mode

open access: yesEnergy Reports, 2022
Under the “double carbon” goal, distributed generation (DG) with inverters will show an explosive growth trend. The microgrid can operate in different modes as a channel for DG to connect to the main grid.

Troubleshooting Distributed Network Emulation

open access: yes2023 26th Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2023
Distributed network emulators allow users to perform network evaluation by running large-scale virtual networks over a cluster of fewer machines. While they offer accessible testing environments for researchers to evaluate their contributions and for the community to reproduce its results, their use of limited physical network and compute resources can

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/
