Method for operating doubly-fed wind turbine generator as a virtual synchronous machine to provide grid-forming control thereof

A system for operating an asynchronous doubly-fed wind turbine generator connected to a power grid in a grid-forming mode to emulate a virtual synchronous machine, the doubly-fed wind turbine generator comprising a line-side converter coupled to a rotor-side converter via a direct current (DC) link, the system comprising:

• a controller comprising at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
• receiving at least one reference command from an external controller;
• controlling rotor flux of the doubly-fed wind turbine generator using the at least one reference command;
• and
• providing power droop control for the doubly-fed wind turbine generator through at least one of rotor-side reference frame rotation and d-axis flux control.
