Researchers from NREL and General Electric have developed and demonstrated the world’s first Type III utility-scale wind turbine generator, also known as a double-fed induction generator. The turbine can operate in grid-forming mode, meaning it can jump-start the grid during a blackout or operate without the power grid. This new capability could improve grid response to disturbances and even support islanded power grids, creating new market opportunities for this type of wind turbine.
