⚡ dVOC Grid-Forming (Single-Phase Micro-Inverter) ⚡ Is it possible to operate a single-phase micro-inverter, with no ESS, as a GFMI? Absolutely! here’s the proof. My didactic PV inverter [https://lnkd.in/dvuZ43Yb ] is running a grid-forming algorithm, with dVOC as the primary controller. To avoid DC bus overvoltage, I embedded the inverter PQ capability directly before the inner current loop; It was quite tricky, but I eventually implemented a conditional-integration controller in the dq axes. The picture shows the dVOC GFMI synchronised with the real grid, delivering active power. #GridFormingInverter #dVOC #DispatchableVirtualOscillator #ConditionalIntegration #PowerElectronics #HandsOnLearning #HomeLabs

Insightful sir, can you share the hardware specifications and experimental results.

3wOver the past few hours, I have gone a step deeper into the analysis. I introduced a virtual inductance and explored the droop characteristics. While frequency droop shows a linear trend, the reactive power droop follows a non-linear pattern (which, however, remains consistent with the steady-state solution of the employed dVOC equations).
