Precise Hybrid Method for Solving the Selectivity Problem of Overcurrent Relays due to PV Uncertainty [PDF]
International Journal of Research and Technology in Electrical IndustryPhotovoltaic (PV) power plants include several parallel and series units. PV uncertainty due to scheduled or forced outages of these units affects the coordination of overcurrent relays (OCRs) and may violate the optimization constraint.

Energy Science &Engineering, Volume 13, Issue 3, Page 1171-1183, March 2025.High‐impedance fault (HIF) and load variation signals are sampled using EMTP‐RV and exported to MATLAB. DWT is applied to extract features, which are then input into the SVM algorithm to detect HIFs and distinguish them from other network phenomena. ABSTRACT High impedance faults (HIFs) can lead to crucial damage to the utility grid, such as the risk ...

Research and design of distributed intelligent electronic pulse barring facility
Journal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.Abstract Because traditional barring facilities have difficulty in controlling the water surface and have low intelligence degree, a new type of intelligent electronic pulse barring facility was developed. The system established a dynamic charging and discharging model, an electric field strength calculation model, and a forward reverse rotation ...
