System and method for providing grid-forming control for a double-fed wind turbine generator using virtual impedance

A system for providing grid-forming control of a double-fed wind turbine generator connected to an electrical grid, the double-fed wind turbine generator having a line-side converter coupled a rotor-side converter via a DC link, the system comprising:

• a controller comprising at least one processor, the at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
• receiving at least one control signal associated with a desired total power output or a total current output of the double-fed wind turbine generator;
• determining a contribution of at least one of power or current from the line-side converter to the desired total power output or to the total current output of the double-fed wind turbine generator, respectively;
• determining a control command for a stator of the double-fed wind turbine generator based on the contribution of at least one of the power or the current from the line-side converter and the at least one control signal;
• and
• using the control command to regulate at least one of power or current in the stator of the double-fed wind-turbine generator.
