The invention relates to a wind power consumption ability analysis method. The method comprises the following steps: 1) data of a power system are acquired; 2) the start-up mode of the power system is determined, and the minimal start-up capacity of a non-wind turbine generator is determined according to the start-up mode of the power system; 3) the thermal stability limit and the transient stability limit of each main transmission channel and the maximal transmission capacity of each main transmission channel are calculated; 4) the maximal wind power output provided by each hour is calculated; 5) the wind power output based on network constraints is calculated; 6) the wind power accommodation space based on the system peaking capability is calculated and obtained; 7) the actual wind power output and the maximal transmission capacity of each main transmission channel are calculated, and the limited output of each main transmission channel in the power system is calculated respectively and correspondingly; 8) wind power generation is calculated, and the wind power limit is calculated; and 9) an abandoned wind power ratio is calculated. The method of the invention can intuitively and accurately represent the wind power consumption ability by the power system.
