The file contains the numerical data for simulation of the application case reported in the paper "Adaptive Feedforward Grid-Forming Controls to Preserve Inertial Capabilities in Power Systems". The paper presents a novel adaptive feedforward grid-forming control, which is specifically designed to preserve the inertial capabilities of grid-forming controls without feedforward terms, and at the same time to ensure the damping capabilities provided by the feedforward grid-forming converters to the system.
