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 …

Power systems are experiencing structural changes induced by the integration of distributed
generation units and the operation of microgrids. This transformation has posed new …

In the presence of distributed generation (DG), it is important to assure a fast and reliable
protection system for the distribution network to avoid unintentional DG disconnection during …

Distributed electricity resources (DERs) are power generating sources which are installed to
meet the increasing peak demand. Renewable and zilch emission characteristics are …

In this paper, coordination strategy that considers using user defined characteristics for the
inverse time overcurrent relays is proposed. Typically, the coordination between relays …

In this paper, an improved bio-inspired optimization algorithm called Seagull Optimization
Algorithm (ISOA) is proposed. ISOA is developed based on three techniques, these …

With the penetration of renewable energy sources based distributed generation (RES-DG) in
the distribution network (DN), the operating time of protection relays becomes a major …

The modern power system networks are very complex and often consist of multiloop
structures with increased penetration of renewable energy sources‐based distributed …

This paper presents a new method for coordination of directional overcurrent relays to
reduce the discrimination time of the primary and backup relays, by using nondominated …

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 …
