The invention relates to a wind power considered thermal power frequency modulation unit configuration method, in particular to a regional power grid thermal power frequency modulation unit configuration method considering wind power uncertainty fluctuation, in order to solve the problem of influence caused on system frequency stabilization after large-scale wind power integration. The method includes: performing decomposition and restructuring of a wind power time sequence by taking a Mallat wavelet decomposition and restructuring algorithm as a tool, establishing an instantaneous model of second-scale and minute-scale wind power plant power uncertainty fluctuation on the basis of a wavelet multi-scale analysis method, giving a time-domain instantaneous expression prior to establishing a wind power regional power grid model used for frequency modulation analysis, giving an expression for representing primary and secondary frequency modulation capacities of the system based on the frequency modulation analysis, and quantitatively analyzing and computing the primary and secondary frequency modulation capacities of the system under different conditions on the basis of the frequency modulation capacity expression. By the method, system frequency fluctuation caused by wind power fluctuation can be reduced, and system frequency stability is maintained. The method is applicable to wind power considered thermal power frequency modulation unit configuration.
