Analysis of necessary primary reserve of a high wind penetration power system

Abstract

The increasing wind power penetration poses a great challenge to the operation stability of the traditional power system. The current mainstream wind turbines are variable speed wind turbines. Some of the traditional power supplies are replaced by large-scale wind power integration. The inertia of a variable speed wind turbine is decoupled by power electronic converters from the power network and therefore does not intrinsically contribute to power system inertia. The principle of the power system frequency regulation is introduced. The primary frequency response of the high wind penetration power system is analysed based on a typical power system frequency response model and the primary frequency characteristic of the wind turbine. Necessary primary reserves provided by wind farms are studied based on the real data of a specific power system.
