Embodiment 1

[0047] Such as figure 2 Shown is a detailed flowchart of a method for determining a feasible solution for comprehensive energy dispatching in a steel enterprise provided by an embodiment of the present invention. figure 2 It can be seen that the embodiment of the method for determining a feasible solution for the comprehensive energy dispatching of a steel enterprise provided by the present invention includes:

[0048] In the embodiment of the present invention, step 1 is the process of initializing the integrated energy dispatching problem of the iron and steel enterprise according to the network topology of the energy system of the iron and steel enterprise, and further includes:

[0049] Step 101: Establish an energy medium pipe network information set E={GAS, STM, ELE,...} and a unit equipment information set Ψ={MIX, PRE, HLD, EMI, BOI, TUR, VAL,...}.

[0050] GAS, STM and ELE are gas, steam and electric energy medium subsets respectively; MIX, PRE, HLD, EMI, BOI, TUR and VAL ar...

Embodiment 2

[0128] The second embodiment provided by the present invention is a specific application embodiment of a method for determining a feasible solution for comprehensive energy dispatching of a steel enterprise provided by the present invention, such as image 3 Shown is the topological structure diagram of the gas subsystem of a typical steel enterprise, Figure 4 It is the topological structure diagram of the steam and power subsystem of a typical steel enterprise. by image 3 It can be seen that the main by-product gases of iron and steel enterprises are blast furnace gas (BFG), coke oven gas (COG) and converter gas (LDG), which are produced by blast furnace, coke oven and converter respectively. The main lines of various gas media are equipped with corresponding gas tanks and dispersing towers, and the main production process users, such as ironworks, steel plants and wide and heavy plate plants, are also connected to different pipe networks. In addition to a single gas medium, ...

Abstract

The present invention is applicable to the technical field of energy dispatching in iron and steel enterprises, and provides a method for determining the feasible solution of comprehensive energy dispatching in iron and steel enterprises, including: establishing the energy medium pipe network information set E, unit equipment information set Ψ and the input or input of each unit equipment The variable set X corresponding to the output variable; judging that there is no directly related unit equipment in the variable set or variables that cannot be calculated based on known input / output variables or that cannot be calculated according to other work / energy / heat conservation or material / mass conservation laws The variables obtained by indirect calculation are free variables; respectively determine the free variables of the unit equipment corresponding to the gas energy medium and steam and electric energy medium to meet the initial value within the corresponding upper and lower limits; set the free variables and The correlation of the non-free variables determines the value of the non-free variables; judges whether the values ​​of the variables in the variable set satisfy the process model constraints of the unit equipment, if yes, record the variable values ​​and output a feasible solution, and if not, adjust the value of the variable set that violates the constraints The value of the variable is judged again, which solves the technical problem of searching for the feasible solution of the integrated energy dispatching of iron and steel enterprises.

Description

Technical field [0001] The invention belongs to the technical field of energy dispatching in iron and steel enterprises, and particularly relates to a method for determining a feasible solution for comprehensive energy dispatching in iron and steel enterprises. Background technique [0002] The iron and steel industry is a fundamental 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 steel industry, and it is also the main cause of environmental load. On the one hand, iron and steel enterprises have long production processes, numerous processes and equipment, and each process is connected to 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 as production and consum...
