Abstract

The invention belongs to the technical field of the energy scheduling of the iron and steel enterprises and provides a method for optimizing integrated scheduling of multiple energy mediums of an iron and steel enterprise. The method comprises obtaining the network topology structure of energy system of the iron and steel enterprise and the demand and output information of major production steps and devices except schedulable critical devices and other commonly-shared auxiliary devices in various subsystems of gas, steam and power on three energy mediums gas, steam and power in a plurality of future scheduling cycles, establishing the scheduling sub-model J1 of the gas subsystem, establishing the scheduling sub-model J2 of the steam subsystem, establishing the scheduling sub-model J3 of the power subsystem, establishing the multi-cycle integrated scheduling model MinJ=J1+J2+J3 for multiple energy mediums of the iron and steel enterprise and taking the sum of constraint conditions that the various subsystems need to satisfy separately as the constraint condition of the multi-cycle integrated scheduling model, and finally, obtaining the integrated scheduling result; the technical scheme of integrated scheduling of multiple energy mediums is provided from the points of integrated scheduling and global optimization and has clear guidance significance for specific practices.

Description

technical field [0001] The invention belongs to the technical field of energy scheduling in iron and steel enterprises, and in particular relates to an optimization method for integrated scheduling of multiple energy media in iron and steel enterprises. Background technique [0002] The iron and steel industry is the basic pillar industry of the national economy, and it is also a resource- and energy-intensive industry. Energy consumption is an important factor that determines the production cost and profit of the iron and steel industry, and it is also the main reason that affects the environmental load. On the one hand, iron and steel enterprises have a long production process with various procedures and equipment, and each process is connected with each other, and each process and equipment is associated with multiple energy media; on the other hand, iron and steel enterprises need to use more than 20 types of energy. These energy media not only have various forms such a...
