The invention provides an electricity-heat integrated energy system scheduling method and system considering variable flow regulation. The method comprises the steps that a correction fuzzy set of wind power uncertainty is constructed; modeling the relevance between the renewable energy prediction error and the prediction output based on the corrected fuzzy set, and establishing a conditional distribution robust scheduling model of the power system containing the random variable; establishing a regional heat supply system scheduling model considering a variable flow regulation mode; converting a model containing random variables in the power system into a deterministic model; solving the deterministic model and the regional heat supply system scheduling model by adopting a double-layer distributed collaborative algorithm, and outputting a scheduling scheme; and the power-heat integrated energy system schedules the output of each unit based on the scheduling scheme, and the distributed cooperative scheduling o
