Embodiment 2

[0126] The embodiment provided by the present invention is a specific application embodiment of the method for determining the feasible solution for optimal scheduling of the iron and steel enterprise by-product gas system provided by the present invention. Taking the Ganxin Iron and Steel 2 million tons project in Kezhou, Xinjiang as the research case of the embodiment of the present invention, Figure 5 A schematic diagram of the network topology of the iron and steel enterprise's energy system is shown, and a feasible solution to the optimal scheduling problem of its by-product gas system is searched. The gas system contains two by-product gas media, blast furnace gas and converter gas, as well as high-speed mixed gas. In addition, since converter gas needs to be used after pressurization, converter gas and pressurized converter gas are regarded as two different media. . The steam system includes two quality grades of medium-pressure steam and low-pressure steam, and the p...

Abstract

The invention is suitable for the technical field of iron and steel energy production and information technology and provides a method for achieving decoupling of an optimization algorithm and an iron and steel enterprise energy integrated scheduling problem. The method comprises a step of establishing a unit mathematical model corresponding to unit equipment; a step of taking the overall cost optimization as an optimization object, and establishing an iron and steel enterprise energy dynamic balance and optimal scheduling mathematical model which can meet various constraint conditions; a step of designing an interface between the iron and steel enterprise energy dynamic balance and optimal scheduling mathematical model and a to-be-called optimization algorithm; a step of calling the optimization algorithm to solve an iron and steel enterprise energy dynamic balance and optimal scheduling problem; and a step of computing an iron and steel enterprise energy balance and scheduling scheme according to a chromosome of the optimal fitness value. According to the method provided by the invention, by defining a smart data structure and a decoupling flow, the optimization algorithm and a technology problem are enabled to have no direct association, and a method of calling only two interfaces of the iron and steel enterprise energy integrated scheduling problem in shared interfaces eliminates the contradiction when the standard optimization algorithm is used for solving the iron and steel enterprise energy integrated scheduling problem.

Description

technical field [0001] The invention belongs to the field of iron and steel energy production and information technology, and in particular relates to a method for realizing the decoupling of an optimization algorithm and an iron and steel enterprise energy comprehensive scheduling problem. 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 me...
