The wide application of microgrid concept leads to challenges for the traditional protection distribution networks because changes in short circuit level and network topology during two modes operation. This paper proposes a promising solution these problems by offering new coordination scheme not affected variation or topology. proposed is based on local measurements at relay location with low...

The resurgent component of voltage-gated Na+ (Nav) currents, INaR, has been suggested to provide the depolarizing drive for high-frequency firing and to be generated by voltage-dependent Nav channel block (at depolarized potentials) and unblock (at hyperpolarized potentials) by the accessory Navβ4 subunit. To test these hypotheses, we examined the effects of the targeted deletion of Scn4b (Navβ...

Magnetism of graphene can be created by atomic defects, either hydrogen adsorption or single-carbon vacancy formation, owing to the unpaired $\ensuremath{\pi}$ electrons around defects. Here we explore, based on rigorous first principles calculations, possibility voltage manipulation two such types magnetism in via a scanning tunneling microscope tip. We find remarkably different behavior. For ...

Medium-voltage direct-current (MVDC) distribution is a possible replacement due to the advancements in power electronic technologies, for existing medium-voltage ac distribution on ships. The new systems based on MVDC are expected to increase fuel efficiency, remove bulky lowfrequency transformers used for voltage coordination, and integrate storage technologies. These expected benefits of MVDC...

Metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. Since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. In this paper, Big Bang – Big Crunch and Hybrid Big Bang – Big Cr...
