Small and large signal stability analysis of IMPSA wind power plant integration on Vietnamese power system

This research presents a study on the small and large signal stability of IMPSA wind power plant with variable speed wind turbines connected to Vietnamese power system. Based on an aggregated wind park model in Power System Analysis Toolbox (PSAT) library, a dynamic model of Ninh Thuan - Binh Thuan grid, a province of Vietnam where a variable speed wind turbine system has been built. The toolboxes such as Power Flow, Time Domain Simulations in PSAT are used to study the small and large signal stability of IMPSA wind power plant and Ninh Thuan - Binh Thuan grid after the occurrence of small and large disturbances, i.e. trip lines and three phase faults, respectively. The different simulation results show how the Vietnamese Wind Power Plant (WPP), equipped with variable speed wind power generators, will respond to disturbances of the buck power system in the near future.
