| Abstract |
Due to the increase in the use of renewable energy sources (RES) and a corresponding reduction inthe conventional energy generation systems, there is nowadays a demand from the power-electronicconverters to provide grid-forming properties through proper control of the converter systems. Thispaper aims at evaluating the impact of various control loops of a grid-forming control strategy equippedwith a fault-ride through capability on the passivity properties of the converter system. Through theanalysis of the frequency-dependent input admittance of the converter, the main factors affecting thepassivity property are identified. A simplified analytical model has been derived in order to proposepossible control modifications to enhance system's passivity at various frequencies of interest and thefindings are verified through detailed time-domain simulations and experiments. |
