Abstract

The invention provides an electro-thermal gas interconnected energy system scheduling method, which aims at realizing dynamic environmental protection and economic flexibility, and establishes a plurality of equipment models with continuous adjustment capability and higher flexibility potential on the basis of acquiring data and information of an electro-thermal gas interconnected energy system. Secondly, a unified steady-state power flow model considering an electric power, thermal power and natural gas sub-heterogeneous energy system is proposed; a dynamic environment-friendly economic flexibility scheduling model is provided on the basis of considering a dynamic environment-friendly scheduling target, a dynamic economic scheduling target and an operation constraint condition; and finally, a multi-objective fuzzy optimization method is adopted to solve the collaborative flexibility scheduling, and the scheduling result information of the electric heating gas interconnected energy system is output. Effectiveness and reasonability of collaborative flexible scheduling of the electric heating gas interconnected energy system are verified, and important basis and theoretical basis areprovided for multi-objective scheduling and system flexibility analysis of the electric heating gas interconnected energy system.
