Distributed Control of Islanded Meshed Microgrids
IEEE Access, 2023 The main objective in microgrids is keeping their frequency and voltage close to the rated values, and ensuring a precise power sharing of their distributed generators (DGs). This can be challenging in a meshed microgrid due to the tight coupling between active and reactive power resulting from its various power line impedances.

Short-Circuit Analysis of DER-Based Microgrids in Connected and Islanded Modes of Operation
Energies, 2021 Since microgrids should be able to smoothly operate in two distinct modes—grid-connected and islanded, their fault currents can widely fluctuate depending on the operational mode. When the microgrid is connected to the grid, the highest fault current, by

Power Sharing in Island Microgrids [PDF]
Frontiers in Energy Research, 2021 The growth of local renewable energy sources and heavy loads in power distribution networks, such as the increasing electric vehicles charging stations, causes several issues with a direct impact on the stability of the electrical grid. An attempt to overcome such issues is the microgrid concept, which has the grid structured into local sub-grids that ...

Adequacy Evaluation of an Islanded Microgrid [PDF]
Electronics, 2021 The reliability of power converters has been extensively examined in terms of component- and converter level. However, in case of multiple generation units, the evaluation of the performance of power systems requires system-level modeling. This paper aims to merge the prior art of reliability modeling of power converters with the adequacy evaluation of

Tradeoffs between AC power quality and DC bus ripple for 3-phase 3-wire inverter-connected devices within microgrids [PDF]
, 2011 Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa.

SCADA system for islanded DC microgrids [PDF]
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017 This paper develops a supervisory control and data acquisition (SCADA) system to monitor an islanded DC microgrid including wind turbine, photovoltaics, and battery units. The SCADA system is based on KingView 6.55, and establishes data communication between the host and the slave computers through intelligent modules and different communication ...
