Frequency response of full-power converter wind turbines: impacts on grid frequency stability

Introduction: Power generation based on fossil fuels has increasingly presented significant challenges due to its detrimental impact on the environment. Consequently, the transition toward more environmentally sustainable power generation methods has become essential. Moreover, the growing penetration of renewable energy sources and the continuous expansion of power systems introduce additional stability challenges. In this context, system inertia emerges as a critical factor in maintaining and ensuring overall power system stability. The ability to predict and respond to the variations of grid frequency is vital for maintaining a reliable power supply. This paper attempts to address this issue by establishing a combined model that couples the wind turbine system to the power grid to assess how renewable energy generation influences power system frequency stability.
