Transition from Islanded to grid-connected mode of microgrids with voltage-based droop control [PDF]
, 2013 Microgrids are able to provide a coordinated integration of the increasing share of distributed generation (DG) units in the network. The primary control of the DG units is generally performed by droop-based control algorithms that avoid communication ...

Power management of islanded Self-Excited Induction Generator reinforced by energy storage systems [PDF]
, 2018 Self-Excited Induction Generators (SEIGs), e.g., Small-Scale Embedded wind generation, are increasingly used in electricity distribution networks. The operational stability of stand-alone SEIG is constrained by the local load conditions: stability can be

Universal and Seamless Control of Distributed Resources-Energy Storage for all Operational Scenarios of Microgrids [PDF]
, 2017 This paper proposes one control paradigm that can operate in both grid-connected and islanded modes, hence, does not need any sort of islanding detection method. The proposed method automatically and seamlessly rides-through a fault on the grid side, and

A Bankruptcy Problem Approach to Load-shedding in Multiagent-based Microgrid Operation
Sensors, 2010 A microgrid is composed of distributed power generation systems (DGs), distributed energy storage devices (DSs), and loads. To maintain a specific frequency in the islanded mode as an important requirement, the control of DGs’ output and charge action ...
