Incremental Phase-Current Based Fault Passage Indication for Earth Faults in Resonant Earthed Networks

open access: yesElectricity, 2023
We propose a method for the fault passage indication of earth faults in resonant-earthed networks, based on phase current measurements alone. This is particularly relevant for electricity distribution systems at medium-voltage levels. The method is based

Optimal Sizing and Placement of Capacitor Banks in Distribution Networks Using a Genetic Algorithm

open access: yesElectricity, 2021
Nowadays, response to electricity consumption growth is mainly supported by efficiency; therefore, this is the new main goal in the development of electric distribution networks, which must fully comply with the system’s constraints.

Impact of the Generation System Parameters on the Frequency Response of the Power System: A UK Grid Case Study

open access: yesElectricity, 2021
The operation and the development of power system networks introduce new types of stability problems. The effect of the power generation and consumption on the frequency of the power system can be described as a demand/generation imbalance resulting from
