Multi-Objective Function Optimization for Locating and Sizing of Distributed ‎Generation Sources in Radial Distribution Networks with Fuse and Recloser ‎Protection [PDF]

Journal of Operation and Automation in Power Engineering, 2021
Power quality, reliability, loss reduction, and fault clearing times are essential factors in distribution networks. Radial distribution networks often face two problems, line losses and voltage drop at the end of the grid.

Analysis of the Voltage Profiles with Uprating Technique by Third Harmonic Voltage Injection

Anais do Simpósio Brasileiro de Sistemas Elétricos 2020, 2020
This paper presents a study concerning the transmission line uprating method by injection of third harmonic voltage (THV). The method has been recently employed as a more economically feasible proposal to raise the transmission voltage level without the requirement for changes in the structural elements of overhead lines.

Impact of environmental conditions on the voltage profile of LV networks [PDF]

2019 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2019
European distribution system operators (DSOs) should meet EN 50160 standard requirements on the whole network. With the development of distributed energy resources (DER), DSOs need to have a better insight of their low voltage (LV) networks. In this paper, we study the joint impact of external conditions (cable temperature, the ground resistivity and ...
