Embodiment

[0273] The topological structure of the dynamic environmental protection, economic flexibility scheduling calculation example of the electricity, heat and gas interconnection energy system in the present invention is as follows: figure 2 As shown, the electric-heat-gas interconnection energy system in the calculation example is mainly composed of a modified IEEE39-node power system, a Belgian 20-node natural gas system, a regional 14-node thermal system, and a variety of flexible electric-heat-gas energy coupling units. The example simulation of the present invention takes typical winter days as the research object, takes the time interval as 1h (ie, the optimal scheduling step), and an optimal scheduling period is divided into 24 time periods. On the MATLAB2018a platform, the data input, processing and interface construction were carried out in the early stage, and the model program was written based on the general commercial optimization software LINGO18.0 platform and the G...

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. The multi-energy interconnected energy system from the perspective of the energy Internet presents the characteristics of deep integration of "source-grid-load-storage". At the same time, the coordination and complementation of different energy sources also makes the multi-energy interconnected energy system have the characteristics of scheduling flexibility, synergy and diversity. . In the field of energy, almost every kind of energy requires the conversion o...
