Abstract
The increasing penetration of inverter-based resources (IBRs) has motivated the development and verification of accurate grid-forming (GFM) control models for use in transient stability and dynamic simulation studies. This thesis presents an implementation of the REGFM_B1 virtual synchronous machine (VSM) model within the Power System Toolbox (PSTess) simulation environment. The implementation extends the baseline REGFM_B1 algorithm with a supplementary relative frequency damping path and a power system stabilizer (PSS). The implemented controller is verified on a simple three-machine test system and validated against an independent ideal VSM baseline implementation through simulations. This work establishes a validated PSTess implementation intended to support future studies of VSM-equipped IBRs in power systems.
