Secondary Control for Islanded Microgrids
2018This chapter introduces concepts, characteristics, advantages, and drawbacks of different secondary control approaches for islanded microgrids. First, multilayer hierarchical control is reviewed, defining the main features and control objectives of each control layer.

Fault Tolerance for Islandable-Microgrid Sensors
2021 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems (DFT), 2021This paper presents defect tolerance strategies for islandable-microgrid sensors both at the sensor level and at the matrix (or deployment) level. A microgrid is a group of interconnected distributed power/energy sources and loads with well-defined electrical boundaries that act as a single controllable entity with respect to the main grid or other ...

Droop control for islanded microgrids
2013 IEEE Power & Energy Society General Meeting, 2013This paper contains an explanation of droop control to distribute load changes amongst inverter-sourced generators in an islanded microgrid. As the load within the microgrid changes, the inverter-sourced generators will share this change in load but this paper shows that the change will be arbitrary and droop achieves a regulated change.

Induction Motor Starting in Islanded Microgrids
IEEE Transactions on Smart Grid, 2013Motor loads require high amount of reactive power for a short period during their startup. The high reactive power drawn from the system causes voltage dips at startup time and potentially overvoltage after motor startup is over. The voltage dip and overvoltage may cause the relays to trip and the system to go unstable.

Power quality enhancement in islanded microgrid
2017 Iranian Conference on Electrical Engineering (ICEE), 2017In recent years, the penetration of distribution generations (DGs) has increased. Also the role of distributed generation has significantly increased not only as power generator, but also as an important factor in power quality improvement. In this paper, a method is proposed for reducing the voltage unbalance while the DG is not connected to the grid.

Islanding control of DG in microgrids
2009 IEEE 6th International Power Electronics and Motion Control Conference, 2009This paper discusses islanding control of power electronics interfaced distributed generation (DG) systems in microgrids. Particularly, the following topics will be addressed: microgrid sytem configurations and features, grid-connected system control mode, transient analysis during power outage, islanding detection and load shedding, standalone system ...

Forecast-based Optimization of Islanded Microgrids
2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018In the context of the energy transition, the operational management of microgrids becomes an issue of increasing importance. In this paper, we compare two optimization models for planning generators and storage units in an islanded microgrid, while dealing with uncertainty in load- and PV-forecasts.

Microgrids energy trading in islanding mode
2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm), 2012In this paper, we address the case where two microgrids are isolated from the main power grid but can exchange energy with each other in a peer-to-peer (P2P) manner. The goal is to minimize the total cost resulting from energy generation and transportation, while each microgrid satisfies its local power demand.

Robust control of an islanded microgrid
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012A variety of distributed control strategies have been applied to microgrids, including master-slave, current mode control, and droop [1], [2], [3]. Droop control has received a great deal of attention and has been implemented with rudimentary modifications in order to improve performance [4], [5].
