The invention relates to the technical field of energy collaborative management, in particular to a cold region wind-solar-thermal energy storage comprehensive energy collaborative management method and system. According to the method, the topological stability of each node in a power grid is obtained, so that an analysis window reference value of an electric power parameter sequence of each node is obtained; then, the change stability of each node is obtained to adjust the reference value of an analysis window, so that the electric power parameter sequence of each node is segmented, the dimension correlation among different types of electric power indexes is analyzed and obtained among the segments, and then the dimension contribution degree of the dimension corresponding to each type of electric power index is obtained; and performing anomaly detection on the multi-dimensional power data at all nodes. According to the method, the stability of the nodes in the power grid topological structure and the similar
