Robust AC Voltage Regulation of Microgrids in Islanded Mode with Sinusoidal Internal Model
SICE Journal of Control, Measurement, and System Integration, 2017 This paper shows that the H∞ control is an effective tool for electric voltage regulation. We here consider robust AC voltage regulation of microgrids in an islanded mode.

Cooperative Control to Enhance the Frequency Stability of Islanded Microgrids with DFIG-SMES
Energies, 2013 The issue of frequency stability of microgrids under islanded operation mode and mode transfer has attracted particular attention recently. In this paper, a cooperative frequency control method, which consists of a microgrid central control (MGCC) and ...

A Communication Framework in Multiagent System for Islanded Microgrid
International Journal of Distributed Sensor Networks, 2012 Microgrids are integrated energy systems consisting of interconnected loads and distributed energy sources which as a system can operate in parallel with the grid or in an island mode.

IET Generation, Transmission & Distribution, 2023 One of the main capabilities of grid‐forming converters is the ability to operate in both islanded and grid‐connected modes. The grid‐forming converters work autonomously and behave as an AC voltage source when they are isolated from the bulk power ...

Avoiding the non-detection zone of passive loss-of-mains (islanding) relays for synchronous generation by using low bandwidth control loops and controlled reactive power mismatches [PDF]
, 2014 Generation connected to electrical distribution systems requires reliable and timely detection of loss of-mains (islanding). Passive loss of mains detection relays typically use measurements of parameters such as frequency, phase, and the magnitudes of ...

Rotating accelerator-mode islands
Physical Review E, 2007 The existence of rotating accelerator-mode islands (RAIs), performing quasiregular motion in rotational resonances of order $m>1$ of the standard map, is firmly established by an accurate numerical analysis of all the known data. It is found that many accelerator-mode islands for relatively small nonintegrability parameter $K$ are RAIs visiting ...

Metastability and dynamic modes in magnetic island chains
Journal of Physics: Condensed Matter, 2021 Abstract The uniform states of a model for one-dimensional chains of thin magnetic islands on a nonmagnetic substrate coupled via dipolar interactions are described here. Magnetic islands oriented with their long axes perpendicular to the chain direction are assumed, whose shape anisotropy imposes a preference for the dipoles to point ...
