Microgrid, which is one of the main foundations of the future grid, inherits many properties of
the smart grid such as, self‐healing capability, real‐time monitoring, advanced two‐way …

This paper presents an overview on optimal overcurrent relay coordination in protection
system and protective relays. Efforts have been made to include all methods used for the …

Microgrids can be operated either grid-connected to reduce system losses and for peak
shaving or islanded to increase reliability and provide backup power during utility outage …

In this paper, a comparative study of different meta-heuristic optimization approaches, which
had been proposed in the literature for directional overcurrent relay coordination (DOCRs) …

In this work, interior point method based protection coordination schemes are presented for
coordinating directional overcurrent relays. Also, for minimizing the operating times of …

The coordination problem of directional overcurrent relays (DOCRs) is a non-linear and non-
convex optimization one. Until now, several methods based on the heuristics and non-linear …

The relay coordination problem is of dire importance as it is critical to isolate the faulty
portion in a timely way and thus ensure electrical network security and reliability. Meanwhile …

The coordination of directional overcurrent relays (DOCRs) in meshed power grids with
multiple sources is a constrained optimization problem, which has been stated in recent …

In interconnected networks, it is impossible to satisfy all coordination constraints. Some
methods have been proposed in the literature to determine the minimum break point set …

Conventional protection schemes in the distribution system are liable to suffer from high
penetration of renewable energy source-based distributed generation (RES-DG). The …
