Emission of greenhouse gases and depletion of fossil fuel reserves are two key drivers,
which are forcing the mankind to generate the future energy demand from the renewable …

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 …

Coordination of directional overcurrent relays in a multiloop subtransmission or distribution
network is formulated as an optimization problem. In this paper, the coordination of …

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) …

The time of operation of overcurrent relays (OCRs) can be reduced, and at the same time,
the coordination can be maintained, by selecting the optimum values of time multiplier …

Nowadays, distributed generations (DGs) and microgrids play a significant role in
development of power systems, but DGs produce several protection problems especially in …

One major concern in using over current relays (OCRs) is their coordination in power system
protection to decrease the pressure of electrical equipment and avoid mal‐trip in the primary …

This article has four main objectives. These are: to develop the dynamic fitness-distance
balance (d FDB) selection method for meta-heuristic search algorithms, to develop a strong …

The modern power distribution networks are very complex due to the growing integration of
distributed generators in recent years. Optimal coordination of directional overcurrent relays …

A new objective function (OF) has been proposed for mathematical formulation of directional
overcurrent (OC) relay coordination in interconnected networks. The fuzzy-based genetic …
