In recent years, with the rapid development of renewable energy power generation, the operation and structure of the power grid are becoming more and more complex, the difficulty of power balance and frequency regulation is increasing. North-west Power Grid took the lead in carrying out renewable energy frequency modulation function transformation and performance test technology research in 2016, and developed a primary frequency modulation function test method for renewable energy stations in the North-west transmission-end large power grid. In this paper, by calculating and analyzing the response data of some renewable energy stations when Yindong HVDC is blocked, combined with the fast frequency response performance test results of a renewable energy station, this paper analyzes the shortcomings of the current fast frequency response function test methods of the renewable energy stations of the North-west Power Grid, and put forward suggestions for improvement to provide technical support for the promotion of the primary frequency modulation function of renewable energy stations in the northwest transmission power grid.
