A flexible scheduling method for electric, heat and gas interconnected energy systems

Abstract

The invention provides a flexible scheduling method for an electric-heat-gas interconnected energy system. The method aims at realizing dynamic environmental protection and economic flexibility. Then, a unified steady-state power flow model considering power, heat, and natural gas sub-heterogeneous energy systems is proposed; secondly, on the basis of considering dynamic environmental protection dispatching objectives, dynamic economic dispatching objectives and operating constraints A dynamic environmental protection and economic flexibility scheduling model is proposed. Finally, a multi-objective fuzzy optimization method is used to solve the collaborative flexibility scheduling, and the information on the scheduling results of the electricity, heat and gas interconnected energy system is output. The effectiveness and rationality of the present invention for the coordinated flexible scheduling of the electric-heat-gas interconnected energy system has been verified, and provides an important basis and theoretical basis for the multi-objective scheduling and system flexibility analysis of the electric-heat-gas interconnected energy system.

Description

technical field [0001] The invention relates to an electric-heat-gas interconnection energy system, in particular to a flexible scheduling method for an electric-heat-gas interconnection energy system. Background technique [0002] With the trend of diversification and distribution of energy demand, energy utilization is developing in the direction of multi-energy complementation and mutual assistance, and the interconnection of multi-energy systems has become an important development direction of the Energy Internet.
