A Decentralized Output Feedback Controller to Improve Power System Damping with Virtual Synchronous Machines

Virtual synchronous machine (VSM) is a promising control strategy for inverter-based resources (IBRs) as it can provide desired inertia and frequency support in an inverter-dominated grid. However, it can potentially introduce frequency and power oscillations among multiple IBRs in a similar way as synchronous machines oscillate against each other. To overcome this challenge, a decentralized outpu...
