Microgrids (MGs) use renewable sources to meet the growing demand for energy with
increasing consumer needs and technological advancement. They operate independently …

The power grid infrastructure has evolved from a centralized to a distributed model utilizing
renewable energy sources in the last few years. This trend is likely to continue, given the …

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

Tripping time and optimal overcurrent coordination are nowadays one of the main power
system protection concern, due to the high penetration of renewable energy sources in the …

This paper presents a new hybrid algorithm of Harris hawks' optimization with sequential
quadratic programming (HHO-SQP) for optimal coordination of directional overcurrent relays …

In recent years, power grid infrastructures have been changing from a centralized power
generation model to a paradigm where the generation capability is spread over an …

This paper addresses the problem of Distribution Systems Reconfiguration (DSR), which
consists of finding the state of switching devices (open or closed) in a given distribution …

This article provides a comprehensive review of optimal relay coordination (ORC) in
distribution networks (DNs) that include distributed generators (DGs). The integration of DGs …

Protection coordination of AC microgrids (MGs) is a challenging task since they can operate
either in grid-connected or islanded mode which drastically modifies the fault currents. In this …

The ever increasing presence of renewable distributed generation (DG) in microgrids is
imposing new challenges in protection coordination. The high penetration of renewable DG …
