The recent development of protection coordination schemes based on inverse of AC microgrid: A review
IET Generation, Transmission &Distribution, Volume 18, Issue 1, Page 1-23, January 2024.The traditional OCR faced many protection performance challenges and miss‐coordination events due to the high DG penetration. Therefore, the main goal of using the voltage value that the relay discovers is to offer reliable relay coordination under high DG penetration.

Feasible protection strategy for HVDC system by means of SFCL and passive resonance DC breaker
The Journal of Engineering, 2019 The key obstacle in implementing high-voltage direct current (HVDC) grid, which is considered as the future of power grid, is the absence of effective DC circuit breaker (DCCB). At present, HVDC grid could be based on half-bridge (HB) or full-bridge (FB)

Transient Stability Improvement using Resistive-type Superconducting Fault Current Limiters (R-SFCL)
International Journal of Engineering Technology and Sciences, 2019 The rapid growth in the demand for electrical energy due to the astronomic growth in population has led to increase in the system fault current levels. This increase in fault current if not properly checked, could lead to system collapse. Superconducting Fault Current Limiters (SFCLs) are used in power system networks to mitigate against high fault ...
