SSR Analysis of DFIG-Based Wind Farm With VSM Control Strategy

SSR Analysis of DFIG-Based Wind Farm With VSM Control Strategy

The wind turbine is usually integrated into the power grid via back to back converter, and the inertia is decreased. Virtual synchronous machine (VSM) control was proposed to improve inertia of the wind farm. While for the doubly-fed induction generator (DFIG)-based wind farm with traditional contro...
