Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] like Figure 1 As shown, this embodiment of the invention provides a method for establishing a demand response strategy for electrolytic copper industrial loads that consider process characteristics and production safety constraints. The method includes: Step 1, analyzing the process characteristics of electrolytic copper loads and the power characteristics of production equipment; Step 2, analyzing the effective response and assessment mechanism of demand response, establishing a demand response benefit settlement model, and proposing a demand response reporting and control model for electrolytic copper industrial loads that consider process characteristics and production safety constraints.

[0072] Specifically, this embodiment of the invention provides the following details for step one: analyzing the characteristics of the electrolytic copper load process flow and establishing a resource task network model for the electrolytic copper industrial load process flow. The electrolytic copper industrial load process flow includes the following steps: raw material preparation, pyrometallurgical copper smelting, oxygen production, auxiliary smelting, electrolytic refining, and acid production. The steps with power control feasibility are raw material preparation, oxygen production, auxiliary smelting, electrolytic refining, and acid production. The step with switching capability is electrolytic refining. Power control or switching is not possible in the pyrometallurgical copper smelting step. A schematic diagram of the process flow is shown below.Figure 2 As shown.

[0073] Specifically, in the electrolytic copper process, the raw material preparation stage provides ore and solvent for subsequent stages; the oxygen production stage provides oxygen for the pyrometallurgical copper smelting stage; the capacity enhancement stage provides air for the pyrometallurgical copper smelting stage; the side-blown smelting stage consumes ore and solvent to provide matte for the top-blown smelting stage; the top-blown smelting stage consumes matte to provide blister copper for the anode copper smelting stage; and the anode copper smelting stage consumes blister copper to provide anode copper for the electrolytic refining stage.

The pyrometallurgical copper smelting stage consumes oxygen and air to provide sulfur dioxide for the sulfuric acid production stage. The electrolytic refining stage consumes anode copper to produce cathode copper. In summary, the resource-task network model of the electrolytic copper process is as follows: Figure 3 As shown, MP, SBS, TBS, AFS, C, ER, PO, V, and PA represent, in order, the material preparation stage, side blowing stage, top blowing stage, anode furnace smelting stage, casting stage, electrolytic refining stage, oxygen production stage, auxiliary smelting stage, and acid production stage. ia R ib R ic R id R ie R pc R io R ca R is R ps The components are listed in the following order: raw materials, matte, crude copper, liquid anode copper, solid anode copper, cathode copper, oxygen, compressed air, sulfur-containing flue gas and sulfuric acid.

K is the set of process stages, n. k Let k be the number of devices in process stage k. Based on the power control characteristics of the equipment, there are limits to the adjustable power control of production equipment in different process stages. In actual production, the quantity of materials is also constrained. If the quantity of materials exceeds a certain threshold during the production cycle, material storage and management costs will be incurred; if the quantity is too low, it will affect the normal production of subsequent stages. Furthermore, the quantity of product materials needs to meet certain requirements within each production cycle to satisfy production demands. In summary, the constraints related to adjustable production equipment power control and material quantity are expressed as follows:

This is a constraint on the number of products produced within the production cycle.

[0083] It is worth noting that the above RTN model describes the changes in power control status of production equipment and the time scale of material production and consumption at 15 minutes. The interaction between materials and process links during production is considered a discrete process, occurring only at the beginning or end of a time period. For non-adjustable production processes such as pyrometallurgical copper smelting and casting, their power control status is as follows:

[0086]

[0087]

[0088]

[0089]

[0090] Among them, W ER,i Q is the chemical energy required for the electrolysis process. ER,i H represents the heat lost during the reaction. ER,i This is the heat energy converted during the electrolysis process. Let be the thermal energy conversion efficiency of the i-th electrolytic cell.

ER,i Let m be the specific heat capacity of the solution in the i-th electrolytic cell. ER,i Let be the mass of the solution in the i-th electrolytic cell.

[0091] Power control in the electrolytic refining process affects the temperature of the electrolytic cell solution. The electrolytic cell solution needs to be within a certain temperature range to ensure the normal production of the cathode copper product. The relationship between the electrolytic cell solution temperature and the quantity of cathode copper can be expressed as:

[0092]

[0093] in, The efficiency of producing cathode copper in an electrolytic cell is affected by the temperature of the electrolytic cell solution.

[0094] Specifically, this embodiment of the invention provides the following details for step two: analyzing the effective response and assessment mechanism of demand response, establishing a demand response revenue settlement model, and proposing a model for the participation of electrolytic copper industrial load in demand response reporting and control, considering process characteristics and production safety constraints. Generally, the settlement mechanism for the response costs and assessment costs of industrial load participating in demand response can be expressed as follows:

Over-response refers to an actual response power exceeding the reported quantity, while under-response refers to an actual response power less than the reported quantity; both will be subject to performance penalties.

[0105] When loads participate in demand response, the response market has certain requirements for response effectiveness and response capacity reporting, such as effective response determination and reporting response capacity constraints, as specifically stated below:
