Transient Energy Shaping Strategy for Grid‐Forming Converters Based on the Port‐Hamiltonian Framework

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the transient stability of grid‐forming converters (GFMs) in converter‐based grids (CBGs) without main grid support, with emphasis on the impact of current‐limiting control on the stability region. Unlike conventional Lyapunov‐based approaches, which are difficult to construct and extend to new controllers, we propose a Port ...
