Recently, the penetration of Distributed Generation (DG) at medium and low voltages in utility networks is increasing in developed countries and takes special place for them worldwide. Due to the DGs advantages, including using of Renewable Energy which not polluting environment and has endless nature, the application of DGs can potentially reduce the need for traditional system expansion, cont...

This paper proposes two control strategies for the islanding operation of hybrid microgrid with a high penetration of wind driven cage induction generators. The control strategies combine approaches traditionally applied to self-excited cage induction generators with recent approaches for microgrid’s islanding operation. The proposed control strategies aim to facilitate the higher integration o...

 Abstract— The optimal planning problem of provisional microgrids, as a new class of microgrids, is investigated in this paper. Unlike traditional microgrids, provisional microgrids do not possess the islanding capability and are dependent on one or more electrically connected microgrids, called coupled microgrids, for islanding purposes. Provisional microgrids can be considered as enablers of...

At present, the main form of microgrid is AC grid. DC microgrids have received extensive attention and research with rapid development various power. The operation mode divided into grid-connected islanding operation. Islanding formed after circuit breaker tripped, which connects to large can be planned unplanned islanding. Unplanned will cause certain harm users systems, so it necessary detect...

It is well known that certain materials show a granular structure in their surfaces, with hills of several heights and lateral extensions. Thermodynamic and kinetic determine how the film surface develops. Thermodynamic dictates the growing process, layer by layer, islanding or by a mixed mechanism. Kinetic plays an equally important role since island nucleation and growth is controlled by surf...
