Generalized Multivariable Grid-Forming Control Design for Power Converters [PDF]
IEEE Transactions on Smart Grid, 2022 The grid-forming converter is an important unit in the future power system with more inverter-interfaced generators. However, improving its performance is still a key challenge. This paper proposes a generalized architecture of the grid-forming converter from the view of multivariable feedback control.

Multivariable Grid-Forming Converters With Direct States Control
IEEE Transactions on Industry Applications, 2022 A multi-input multi-output based grid-forming (MIMO-GFM) converter has been proposed using multivariable feedback control, which has been proven as a superior and robust system using low-order controllers. However, the original MIMO-GFM control is easily affected by the high-frequency components especially for the converter without inner cascaded ...
