Synchronverter with Virtual Resistor-Based Frequency Control Technique Applied in Doubly-Fed Induction Generator

This work presents a novel primary frequency control approach that associates the grid-side converter (GSC) of a doubly-fed induction generator (DFIG) with a Synchronverter. To evaluate the proposal, simulations of the model will be performed in an IEEE 14-bus test system, in PSCAD/EMTDC, where DFIG will replace some synchronous machines. From a frequency variation scenario, it will be demonstrated that the technique based on Synchronverter presents improved performance by attenuating a frequency drop when compared to the conventional strategy.
