Background Technology

[0002] The large-scale grid connection of new energy sources places higher demands on the flexibility of power system regulation. The volatility and intermittency of renewable energy sources such as wind power and photovoltaics exacerbate the pressure on grid frequency and voltage regulation, and traditional thermal power peak-shaving methods face transformation challenges under environmental and economic constraints. Against this backdrop, the potential for flexible regulation of demand-side resources, especially industrial loads, has attracted widespread attention, with demand response technologies such as interruptible loads and adjustable loads becoming research hotspots both domestically and internationally. Yunnan Province has abundant new energy and industrial load resources, and electrolytic copper loads are a typical industrial load in the region, characterized by high energy consumption and multiple process flows. However, the production process characteristics of electrolytic copper industrial loads are complex, with significant differences in the power characteristics of different production equipment, making it difficult to characterize the coupling relationships between different processes. Power regulation can affect the material supply between different processes, indirectly affecting the normal production order of electrolytic copper industrial loads and even production safety. Considering the process characteristics of electrolytic copper industrial load production, establishing a model that can characterize its production process state is of great significance for its participation in grid interaction. Summary of the Invention

This invention provides a method for establishing a resource-task network model of the electrolytic copper process flow that considers process coupling. Based on the characteristics of the electrolytic copper production process and the material interaction relationships between process steps, it analyzes how key production parameters affect production order and production safety constraints. Production equipment, materials, and electricity in the electrolytic copper process flow are abstracted as resources, and operations that produce / consume specific sets of resources are abstracted as tasks, thus establishing a resource-task network model of the electrolytic copper process flow that considers process coupling.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0051] like Figure 1 As shown, this embodiment of the invention provides a method for establishing a resource task network model for an electrolytic copper process considering process coupling, including: Step 1, analyzing the characteristics of the electrolytic copper load process and the power characteristics of the production equipment; Step 2, analyzing the material coupling relationship in the electrolytic copper load process and the production safety constraints of the electrolytic copper industrial load, and establishing a resource task network model for an electrolytic copper process considering process coupling.

[0052] Specifically, this embodiment of the invention provides the following details for step one: Analyzing the characteristics of the electrolytic copper load process flow, the process flow of the electrolytic copper industrial load includes the following steps: material preparation, pyrometallurgical copper smelting, oxygen production, auxiliary smelting, electrolytic refining, and acid production. The material preparation step includes a series of sub-steps such as material transportation, material crushing, and material stirring, providing raw materials for subsequent steps. The production equipment for material transportation is a variable frequency motor. The power consumption of subsequent sub-steps depends on the quantity of material processed. Changing the drive frequency of the variable frequency motor changes the material transportation rate, indirectly changing the quantity of material processed in subsequent sub-steps, thereby achieving power regulation of the entire material preparation step. The main production equipment for the oxygen production, auxiliary smelting, and acid production steps are an air compressor, a blower, and a negative pressure fan, respectively. These equipment structures have inlet guide vanes, and the volume of gas introduced can be adjusted by changing the rotation angle of the inlet guide vanes, thus achieving power regulation of the process. The main production equipment for the electrolytic refining step is an electrolytic cell, whose power depends on the magnitude of the DC current. Current control is typically achieved by adjusting the voltage drop of the saturated reactor or the on-load tap changer. It is worth noting that the solution in the electrolytic cell needs to be maintained at a certain temperature to ensure the normal operation of electrolytic refining; therefore, the aforementioned process steps have the feasibility of power control. In the pyrometallurgical copper smelting process, the intermediate products matte and crude copper are liquid and cannot be stored or transferred across production lines. Furthermore, the main production equipment is not electrical equipment; therefore, the pyrometallurgical copper smelting process does not have the feasibility of power control. In summary, the electrolytic copper load process flow is as follows: Figure 2 As shown.

[0053] 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 intensified smelting 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. Since the anode copper obtained from the anode furnace smelting is liquid, a casting stage is required to cast the liquid anode copper into solid anode copper. The side-blown smelting, top-blown smelting, and anode furnace smelting stages are collectively referred to as the pyrometallurgical copper smelting 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.

[0054] Specifically, this embodiment of the invention provides the following details for step two: analyzing the material coupling relationships in the process flow and the industrial load production safety constraints of electrolytic copper, and establishing a resource task network model for the electrolytic copper process flow that considers process coupling. For example... 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 order: raw materials, matte, crude copper, liquid anode copper, solid anode copper, cathode copper, oxygen, compressed air, sulfur-containing flue gas and sulfuric acid. The subscripts indicate the quantity of the corresponding production equipment. , This indicates the type of material that interacts with both those that are not restricted by the production line.

[0055] Specifically, for production equipment with power regulation feasibility, its power regulation state can be represented as follows:

[0056]

[0057]

[0058]

[0059] in, , , These represent the power consumed by the i-th device in process step k during time period t under scenario ω, the power control status, and the device switching status. The device switching status is a 0-1 variable, where 0 represents load shedding and 1 represents load activation. Let N represent the rated power of the i-th device in process step k, where N represents the rated power. Let x be the quantity of material x under scenario ω. Let x be the quantity of material x produced or consumed by the i-th machine in process stage k during each time period t. 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:

[0060]

[0061]

[0062]

[0063] in , The power control boundary for production equipment i in process step k is defined by the overline, which is the upper bound, and the underline is the lower bound. , The quantity constraint is for material x. , The quantity of product materials at the beginning and end of the production cycle in this scenario. This is a constraint on the number of products produced within the production cycle.

[0064] 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 uncontrollable production processes such as pyrometallurgical copper smelting and casting, the power control status is as follows:

[0065]

[0066] in, This indicates an uncontrollable production process, where continuous control and cutting equipment are impossible.

[0067] The temperature of the electrolytic cell solution affects the cathode copper production efficiency, and the temperature constraint of the electrolytic cell solution also needs to be considered. The heat balance relationship within the electrolytic cell can be expressed as:

[0068]

[0069]

[0070]

[0071]

[0072] 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; , These represent the heat energy converted into and the heat energy lost during the electrolysis process in time period t and scenario w, respectively. Let be the temperature of the i-th electrolytic cell in time period t under the given scenario. , This represents the temperature boundary within the electrolytic cell. Let be the specific heat capacity of the solution in the i-th electrolytic cell. The mass of the solution in the i-th electrolytic cell; This indicates the temperature of the electrolytic cell in the electrolysis process under scenario w during time period t.

[0073] Specifically, 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:

[0074]

[0075] in, The efficiency of producing cathode copper in an electrolytic cell is affected by the temperature of the electrolytic cell solution. , , , These parameters correspond to formula (2). For material x, the electrolytic refining process ER corresponds to process step k.

[0076] The following section uses a specific scenario simulation case to verify the effectiveness of the resource-task network model for the electrolytic copper process considering the process coupling. The specific scenario and the electrolytic copper load response parameters are shown in Table 1.

[0088] Assuming the electrolytic copper load participates in the demand-side response from 3 PM to 6 PM, based on the above resource-task network model of the electrolytic copper process considering process coupling, the electrolytic copper load production material curve is as follows: Figure 3 As shown, the resource network model can describe the changes in material curves during the production cycle of the electrolytic copper industry load, and can describe the material coupling and interaction relationships between electrolytic copper process links, providing a feasible model basis for the participation of electrolytic copper industry load in grid interaction.
