The invention discloses an electrical-thermal economic dispatching method based on Pareto evolution and a VIKOR method. An economic model is built according to the output model of each unit, and an integrated economic dispatching optimization model based on optimal system operation cost is constructed. The method is characterized in that Pareto front is calculated based on a strength Pareto evolutionary algorithm, and after the Pareto front is obtained, individuals in the Pareto front are sorted in a compromise manner by using a VIKOR method to get an optimal solution of economic dispatching.The constraints corresponding to the subsystems in an integrated system and the network constraints of an electrical system and a thermal system are considered, and thus, the operation cost can be reduced and the utilization rate of energy can be improved in a targeted manner on the premise that the constraints are satisfied. The method can provide support for the abandoned wind power consumptionof regional electrical-thermal energy systems, and can enhance the economical efficiency of regional electrical-thermal energy system dispatching and reduce the operation cost of the system in order to increase revenue.
