Voltage-based droop control of renewables to avoid on-off oscillations caused by overvoltages [PDF]

open access: yes, 2013
To achieve the environmental goals set by many governments, an increasing amount of renewable energy, often delivered by distributed-generation (DG) units, is injected into the electrical power system.

Resynchronization Strategy for a 200kVA Grid- Forming Power Converter

open access: yes2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
During the years, grid connected operation in power systems has been the key factor for renewable energy resource to be able to exchange energy to the electrical grid. However, with the increase of small power systems and micro-grids, the standalone operation and the blackstart of the power system has been increasingly considered a demand in most of ...

Transition from Islanded to grid-connected mode of microgrids with voltage-based droop control [PDF]

open access: yes, 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 ...

Adaptive Grid Impedance Shaping Approach Applied for Grid-Forming Power Converters

open access: yesIEEE Access, 2022
This paper proposes an adaptive grid impedance shaping approach, implemented through a variable structure virtual impedance control strategy (VS-VIS), to improve the power flow control of grid-forming power converters (GF-PC).
