The invention relates to a probability sensitivity index-based wind power point configuration method. The probability sensitivity index-based wind power point configuration method comprises the following steps of 1) proposing a probability sensitivity index of a power system according to a relation between residue and sensitivity; 2) determining a power generator set in strong correlation to a system electromechanical mode according to the probability sensitivity index, and selecting a configuration point scheme; 3) building a doubly-fed induction generator transmission system model accordingto two quality module shaft models; and 4) comparing and analyzing two power generation configuration schemes of influence of addition and replacement on oscillation characteristic of the system by employing characteristic root analysis and dynamic time domain simulation analysis, and obtaining a wind power point optimization configuration scheme according to a calculation result. By the probability sensitivity index-based wind power point configuration method, a reference is provided for wind power point planning on a large scale and the analysis of the low-frequency oscillation characteristics after wind power accessed to a network.
