The recloser-fuse coordination of the distribution networks equipped with distributed generators (DGs) may be jeopardized by using the conventional overcurrent protection strategies thus degrading the network reliability. This research article focuses on the design of a protection coordination strategy based on the dual-setting directional recloser (DSDR) for the effective implementation of a fuse-saving scheme in distribution networks (DNs). The proposed DSDR-based protection strategy will assist the network operators by providing a flexible coordination range along with more accurate protect...

Abstract This research article focuses on the indeterminate protection challenge of the sensitivity deterioration (SD) (also known as protection blindness) of the overcurrent protection (OCP) devices due to the large-scale integration of distributed energy resources (DERs) in the unbalanced distribution networks (DNs). The protection blindness of the OCP has been demonstrated through novel mathematical formulations to quantify the percentage of the sensitivity deterioration for different types of distributed generation (DGs) units and for the varying DG penetration levels. Furthermore, this i...
