Integrated energy system IES reliability evaluation method and system

The invention discloses an integrated energy system IES reliability evaluation method and system, and belongs to the technical field of integrated energy system optimization and evaluation. Accordingto the invention, a complex comprehensive energy system containing cold/heat/electricity/gas and other energy flows and formed by coupling a plurality of devices is used as a research object; by considering the replaceability among the cold load, the hot load and the electric load, the influence of the electricity price on the substitutable load in the cold load and the hot load are respectively described by adopting a thermal-electric load cross elastic coefficient and a cooling-electric load cross elastic coefficient; operation constraints, considering operation state constraints, of multiple types of energy storage, AA-CAES power stations, gas turbines and other devices are set, so that the operation state constraints of the devices and the constraints of climbing, starting and stoppingtime, working condition c
