Embodiment 1

[0047] Such as figure 2 Shown is a detailed flow chart of the method for determining the feasible solution of energy comprehensive dispatching in iron and steel enterprises provided by the embodiment of the present invention. figure 2 It can be seen that the embodiments of the method for determining the feasible solution for the integrated energy dispatching of iron and steel enterprises provided by the present invention include:

[0048] In the embodiment of the present invention, step 1 is a process of initializing the comprehensive energy scheduling problem of iron and steel enterprises according to the network topology of the energy system of iron and steel enterprises, which also includes:

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

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

Embodiment 2

[0128] Embodiment 2 provided by the present invention is a specific application embodiment of a method for determining the feasible solution of comprehensive energy dispatching of iron and steel enterprises provided by the present invention, such as image 3 Shown is the topology structure diagram of the gas subsystem of a typical iron and steel enterprise, Figure 4 It is a topology diagram of the steam and power subsystem of a typical iron and steel enterprise. Depend on 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 network of various gas media is equipped with corresponding gas cabinets and release towers, and the main production process users, such as ironworks, steelworks and wide and heavy plate factories, are also connected to different pipeline networks. In addition to the ...

Abstract

The invention provides a method for determining an iron and steel enterprise energy integrated dispatching feasible solution, and the method is suitable for the technical field of iron and steel enterprise energy dispatching. The method includes the steps that an energy medium pipe network information set E, a unit device information set psi and a variable set X corresponding to the input variables or the output variables of all unit devices are built; the variables of the unit devices which are not directly related to one another in the variable set or the variables which cannot be obtained according to the input/output variable are judged as free variables; whether the free variables of the unit devices corresponding to gas energy media and steam and power energy media meet the initial values within the top and bottom limitation ranges corresponding to the free variables or not are determined respectively; the values of the non-free variables are determined according to the correlation of the free variables and the non-free variables in the variable set; whether the values of the variables in the variable set meet the process model constraint of the unit devices or not is judged, and if yes, the variable values are recorded, and a feasible solution is output; if not, the values of the variable which violate the constraint in the variable set are adjusted, and judgment is conducted again. The method solves the technical problem of searching for the iron and steel enterprise energy integrated dispatching feasible solution.

Description

technical field [0001] The invention belongs to the technical field of energy dispatching in iron and steel enterprises, and in particular 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 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 for...
