Strategy for DC Microgrid Energy Management Based on RG-DDPG

open access: yesZhongguo dianli, 2023
The randomness and intermittency of distributed energy have brought great challenges to the energy management of direct current (DC) microgrids. In order to solve this challenge, a DC microgrid energy management strategy based on reward guidance deep ...

AI in arcing-HIF detection: a brief review

open access: yesIET Smart Grid, 2020
In the past few decades, the arcing-high-impedance fault (arcing-HIF) detection problems have become an important issue in the effectively grounded distribution network. Many solutions have been proposed to address this problem.

Piecewise Linear Power Flow Algorithm of DC Distribution Networks Considering Automatic Adjustment of VSC Control Strategy

open access: yesEnergies, 2023
Voltage source converter (VSC)-based DC distribution networks (DCDNs) can automatically adjust the control strategy of overloaded VSCs to adapt to the variation in renewable energy power, but it brings difficulties to the steady-state performance ...

Response of a small population of greater sage-grouse to tree removal: implications of limiting factors

open access: yesHuman-Wildlife Interactions, 2017
In Utah, greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) range has been reduced to 50% of what is considered historical availability due to habitat degradation and loss. In an effort to improve sage-grouse habitat in southern Utah,

Fault Location in Double Circuit Medium Power Distribution Networks Using an Impedance-Based Method

open access: yesApplied Sciences, 2018
The distribution network is extended throughout cities, towns, and villages. Because of the increase in loads and the decrease in power passageways and public corridor reduction, double circuit lines are increasingly being used instead of single circuit ...
