Abstract
This paper presents an analytical method for calculating the limit proportion of wind power considering the primary frequency modulation and frequency constraints of wind power. By analyzing the response characteristics of primary frequency modulation of double-fed induction generator (DFIG), it is pointed out that the increment of primary frequency modulation power provided by DFIG is less than the expected. In order to accurately calculate the power increment of primary frequency modulation of DFIG, the transfer function model of primary frequency modulation of DFIG is established; the frequency response model of power system considering primary frequency modulation of DFIG is constructed, and the limit value of wind power proportion under frequency constraints is solved by analytical method. The accuracy of the proposed analytical calculation method of wind power limit proportion is verified by MATLAB/Simulink time-domain simulation platform.
