Uninterrupted power supply to BESS based microgrid system using adaptive reclosing approach
IET Generation, Transmission & Distribution, 2021 As more than 80% of faults on overhead lines are temporary (transient) in nature which is caused due to lightning strikes, momentary bird or tree limb contact, wind bringing conductors in contact, etc.

An Adaptive Reclosing Switch Based on Shunt Resistance
IOP Conference Series: Materials Science and Engineering, 2019 Abstract In order to solve problems that the low coincidence success rate of the automatic reclosure of distribution network and short-circuit current has a large impact on the system when it coincides with the permanent fault, a shunt resistance type of adaptive reclosing switch is proposed.

Adaptive Overhead Transmission Lines Auto-Reclosing Based on Hilbert–Huang Transform [PDF]
Energies, 2020 This paper presents a reliable and fast index to detect the instant of arc extinction for adaptive single-pole automatic reclosing (ASPAR). The proposed method is a simple technique for ASPAR on shunt compensated transmission lines using the Hilbert–Huang Transform (HHT). The HHT method is a combination of the empirical mode decomposition (EMD) and the

Energy and Load Curtailment Based Indices in Probabilistic Transient Stability Studies
Journal of King Saud University: Engineering Sciences, 1997 In this paper, stochastic models for both simultaneous and adaptive reclosing are presented and examined using a new set of probabilistic transient stability risk indices. The developed indices are based on load curtailments resulting from bus isolations
