Overview on Grid-Forming Inverter Control Methods

Energies, 2020
In this paper, different control approaches for grid-forming inverters are discussed and compared with the grid-forming properties of synchronous machines. Grid-forming inverters are able to operate AC grids with or without rotating machines. In the past,

A Scalable Control Design for Grid-Forming Inverters in Microgrids [PDF]

IEEE Transactions on Smart Grid, 2021
Microgrids are increasingly recognized as a key technology for the integration of distributed energy resources into the power network, allowing local clusters of load and distributed energy resources to operate autonomously. However, microgrid operation brings new challenges, especially in islanded operation as frequency and voltage control are no ...
