The invention relates to a simulation evaluation method for island operation duration of an integrated energy system, which comprises the following steps: 1) analyzing historical operation data of renewable energy sources and loads in an integrated energy system, representing and extracting a source-load uncertain operation scene in the integrated energy system and an occurrence probability of the source-load uncertain operation scene; 2) according to the extracted uncertain scene of the source load of the integrated energy system, establishing a double-layer optimization model for joint evaluation of the energy network architecture and the operation duration under the island of the integrated energy system; and 3) performing equivalent conversion on the joint evaluation double-layer optimization model of the energy network architecture and the operation duration under the island of the integrated energy system, and solving the optimization model to obtain the operation duration of the island of the integrate
