The embodiment of the invention discloses a method and a system for evaluating the wind power consumption condition of an electric power system containing a flexible thermal power plant. The method comprises the steps: S1, setting system parameters of the electric power system; S2, acquiring the original wind curtailment power of the system in each time period when the flexibility transformation is not carried out; S3, calculating the minimum output of the thermal power plant after the low-pressure cylinder of the thermoelectric unit is cut off and the heat storage device and the electric boiler are started period by period from the initial moment, wherein the minimum output is obtained through calculation according to the original wind curtailment power of each time period before transformation, the power output boundary of the flexible thermal power plant after transformation and a given wind power absorption strategy, that is, distribution of the power generation space of each thermoelectric unit or distri
