Beschreibung
Zusammenfassung:	The invention discloses an electric power system primary frequency modulation capability evaluation method considering wind power random fluctuation influence. The method comprises the following steps: 1, defining an analytical expression of the dynamic primary frequency modulation capability DPFRA of an electric power system; 2, deducing the analytical expression of the DPFRA to obtain an expression of a power system primary frequency modulation capability evaluation index considering the wind power random fluctuation influence; 3, solving the DPFRA to obtain the dynamic primary frequency modulation capability of the power system; and 4, setting a reference standard according to the requirements of different power systems on the primary frequency modulation capability, and guiding the frequency modulation parameters of the wind power generating unit, the hydroelectric generating unit and the thermal power generating unit participating in the primary frequency modulation by a system operator according to the
