Grid-Forming Inverter with Simplified Virtual Synchronous Compensator Providing Grid Services and Grid Support

This paper proposes a Simplified Virtual Synchronous Compensator (S-VSC) model with grid-forming capabilities for microgrid applications. Previous works have shown how the S-VSC can provide grid services (i.e., virtual inertia, current harmonic compensation and reactive support during faults) in grid-feeding configuration. In this paper, the S-VSC model is extended to a grid-forming converter to demonstrate its capability to work in island as well, thus representing a promising solution for the control of a microgrid. The control algorithm is validated on a 15 kVA inverter connected to a scaled microgrid.
