Grid-forming converters (GFM) offer an alternative to traditional converters by providing additional features such as operation in island mode and grid-connected mode, emulating a synchronous generator or providing inertia support, which helps enhance grid reliability. Although most control schemes need to operate in the dq or \(\alpha \beta \) reference frames, some strategies can be used to implement these type of control in single-phase converters. This paper discusses the use of a second-order generalized integrator (SOGI) strategy to implement a dispatchable virtual oscillator control (dVOC) as a GFM strategy in a single-phase cascaded H-bridge multilevel inverter (CHB-MLI). The control scheme enables the converter to operate both in island mode and while connected to the grid, managing voltage and frequency in island mode, and controlling the power delivered when connected to a larger grid. Results are presented for the converter’s operation when supplying loads on island mode, injecting energy into a grid, and during transitions between island and grid-connected modes.
