Conventional protection schemes are vulnerable to varying changes in a microgrid with
different types of distributed generators (DGs), which alter the fault current levels, leading to …

Fault current magnitude in a microgrid depends upon its mode of operation, namely, grid-
connected mode or islanded mode. Depending on the type of fault in a given mode …

This paper proposes a communication assisted dual setting relay protection scheme for
micro-grids with grid connected and islanded capability. Previous work on dual setting …

Microgrids usually operate in grid-connected or islanded mode. Due to substantial variation
in fault current, same protection coordination scheme cannot be applied in both modes …

Nowadays, microgrids play a significant role in the development of modern distribution
networks (DNs). In this context, the ever increasing presence of renewable distributed …

The inclusion of distributed energy resources (DER) in Microgrids (MGs) comes at the
expense of increased changes in current direction and magnitude. In the autonomous mode …

Microgrids can be Distributed Generation (DG) supported distribution systems which are
operated either intact with the main grid or operated independently. The flexibility in …

The wide application of microgrid concept leads to challenges for the traditional protection of
distribution networks because of the changes in short circuit level and network topology …

The penetration of distributed generations (DGs) in the existing power distribution system
imposes severe challenges to the existing protection schemes. The direction and magnitude …

Frequent changes in operating conditions of microgrid affect the coordination of directional
overcurrent relays (DOCRs). This article proposes an adaptive protection scheme to handle …
