Study on Regional Power Grid Stability of Large Scale Wind Power Based on Wind Farm Detailed Model

Wind power generation systems include slow-changing mechanical systems such as wind turbines and drivelines, as well as fast-changing power electronic controls and protection of electrical systems such as surveys, hybrid systems with multiple time scales. It is very important to develop the transient model of wind power with high accuracy to meet the stability analysis of power system as much as possible to meet the actual operating characteristics of wind turbine. This paper focuses on the need of system stability analysis after large-scale wind power integration. Based on the accurate reflection of the failure-tracing wind farm model of wind turbine under grid fault, this paper evaluates the system security and stability after a large number of wind power grid-connected.
