Transient Stability Analysis for Grid-Forming Inverters Transitioning from Islanded to Grid-Connected Mode [PDF]
IEEE Open Journal of Power Electronics, 2022 This paper addresses the transient stability of grid-forming (GFM) inverters when transitioning from the islanded to grid-connected mode. It is revealed that the reconnection of the GFM inverters to the main grid can be equivalent to a step change of the

An Improved Control Scheme for Grid-forming Inverters [PDF]
2019 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2019 In order to reduce the reliance of power grids on conventional (and often non-renewable) generation, reliable and dispatchable converter-interfaced distributed generators (DGs) are required. Instead of relying on large rotating machines for frequency and voltage regulation, it becomes crucial to develop improved control schemes for grid-forming ...

Transient Safety Filter Design for Grid-Forming Inverters [PDF]
2020 American Control Conference (ACC), 2020 Unlike conventional generators, inverter-based generation do not possess any rotational inertia. While grid-forming inverters can synthesize small (virtual) inertia via advanced feedback control loops, additional control mechanisms are needed to ensure safety and security of the power grid during transients.
