Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]

open access: yes, 2015
In this work we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor communication

Reactive power sharing and voltage harmonic distortion compensation of droop controlled single phase islanded microgrids [PDF]

open access: yes, 2014
When paralleling multiple inverters that are capable of operating as an island, the inverters typically employ the droop control scheme. Traditional droop control enables the decentralized regulation of the local voltage and frequency of the ...

Multiagent-Based Reactive Power Sharing and Control Model for Islanded Microgrids [PDF]

open access: yes, 2016
In islanded microgrids (MGs), the reactive power cannot be shared proportionally among distributed generators (DGs) with conventional droop control, due to the mismatch in feeder impedances.

A novel distributed event-triggered control for reactive power sharing based on hierarchical structure in islanded microgrid

open access: yesMeasurement + Control, 2021
Due to line impedance mismatches, nonlinear loads and other reasons, the traditional droop control algorithms have great limitations on the control of reactive power sharing.

Power Management Strategy for Photovoltaic based Distributed Generators Operating in Parallel

open access: yesTransactions on Environment and Electrical Engineering, 2016
In many countries, the grid-code or standards do not allow the Photovoltaic (PV) inverters to exchange reactive power with the grid. Recently, some countries have relaxed the standards.

A novel partial transient active-reactive power coupling method for reactive power sharing

open access: yesInternational Journal of Electrical Power & Energy Systems, 2019
Abstract In this paper, a control strategy has been presented to improve the reactive power sharing among distributed generation units in the islanded microgrids. The proposed control method is based on exerting a partial transient coupling between active and reactive powers.

Accurate Reactive Power Sharing Strategy for Droop-Based Islanded AC Microgrids

open access: yesIEEE Transactions on Industrial Electronics, 2023
In islanded AC microgrids, the mismatched impedances of the interfacing feeders between the inverters and the load bus cause poor reactive power-sharing when the conventional frequency and voltage droop control technique is employed. Such operation endangers the whole microgrid reliability as it may lead to overloading certain inverters and ...

LCC-HVDC Connection of Offshore Wind Farms With Reduced Filter Banks [PDF]

open access: yes, 2013
Despite being more efficient, line commutated converter-HVDC links for the connection of large offshore wind farms have ac-filter bank size as one of their main drawbacks.
