Abstract

The invention relates to a method and a system for judging the influence of wind power plant group output on power system service. The method comprises the steps: carrying out abnormal data processingof operation data of a wind power plant group in an identification period, and obtaining an output sequence of the wind power plant group in the identification period; carrying out Z transformation on the output sequence of the wind power plant group in the identification period; and sampling the output sequence of the wind power plant group in the identification period after Z transformation, and judging the influence of the output of the wind power plant group in the identification period on the peak regulation and frequency modulation service of a power system according to sampling points.According to the technical scheme provided by the invention, based on linear frequency modulation Z transformation, the output convergence data of the wind power plant group is processed and sampled,and the influence of the output of the wind power plant group on the power system service is judged according to the sensitive frequency band where the sampling points are located. The method can beapplied to fluctuation analysis of large-scale wind power plant generated power output convergence data, and technical support is provided for research of the influence of fluctuation analysis on peakregulation and frequency modulation of a power system.

Description

technical field [0001] The invention belongs to the field of business impact of wind power output, and particularly relates to a method and system for judging the impact of wind farm group output on power system business. Background technique [0002] The large-scale development and utilization of renewable energy is an important way to alleviate the current world fossil energy crisis and reduce environmental pollution. As a clean energy with commercial development potential, the proportion of wind energy in the power system has gradually increased in recent years. In the future, the traditional thermal power-based synchronous generating units will be replaced by wind turbines, and the power grid will be a high wind power penetration rate grid. [0003] Due to the randomness and volatility of the output power of wind turbines, when the penetration rate of wind power in the system increases, the impact of fluctuations in the output power of wind turbines on the frequency sta...
