Effective Coordinated Virtual Impedance Control for Accurate Power Sharing in Islanded Microgrid
IEEE transactions on industrial electronics (1982. Print), 2021In a practical islanded microgrid system, the mismatched line impedance causes serious problems, such as inaccurate power sharing and circulating current.

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 ...

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].

Islanding Detection and Enhancement of Microgrid Performance
IEEE Systems Journal, 2018Nowadays, renewable energy sources (RES) are widely used in the distribution system. Despite the advantages of RES in the system, they also introduce some problems such as unintentional islanding, protection concerns, reverse power flow, etc. Due to the unpredictable faults or scheduled maintenance plans, a distribution system can be sectionalized into

Intentional islanding of microgrid
2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA), 2017Reliability and sustainability of power supply between already existing power network and Microgrid (MG) having DGs is ensured by both the grid connected and islanded mode of operations. The selection of mode of operation of a MG is based on technical and economic factors.

Frequency control is the key factor in a renewable energy-based microgrid system. The inherent dynamics and low inertia of most power generating units of microgrids lead to frequency oscillations in the system.

Islanding detection in microgrids
2013 IEEE Power & Energy Society General Meeting, 2013The idea of reshaping existing centralized electricity networks to decentralized small scale local power networks namely micro-grids, operating whether autonomous or interconnected to main distribution grid, became an important discussion. Islanding of a generator inside the micro-grid can cause problems in operation and management of the network ...

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 Strategies for SyRG-PV and Wind-Based Islanded Microgrid
IEEE transactions on industrial electronics (1982. Print), 2021The nonlinearity in the consumption does not maintain steady voltage or frequency; therefore, in this article, a circular limited cycle oscillator frequency locked loop with prefilter (CLO-FLL-WPF) based control for voltage source converter control is ...
