Description

Technical Field

[0001] The present invention relates to the technical field of new energy load resource regulation, and in particular to an industrial load resource power grid interactive regulation method, system, medium and equipment. Background Art

[0002] Renewable energy is the main feature of the new power system. By 2060, the total installed capacity of wind power and photovoltaic power will reach about 60%, which includes not only the increase in the power generation capacity of new energy generators, but also the systematic absorption capacity of new energy power generation. However, there is an inherent contradiction between the intermittent output of new energy such as wind power and photovoltaic power generation and the real-time balance characteristics of power supply and demand.

[0003] In traditional power systems, the real-time balance of supply and demand is mainly achieved by providing flexibility on the power generation side, which is a response of the power generation side to the volatility of the demand side. Although intermittent renewable energy generation has increased power generation, it has also brought challenges: on the one hand, new energy sources such as wind power and photovoltaics have increased the volatility of the power generation side to the demand side, which has greatly increased the system's demand for flexible resources; on the other hand, these new energy sources have squeezed the space for traditional energy generation, further weakening the regulation capacity of the power generation side. Therefore, how to solve the problem of the dual deterioration of supply and demand of flexible resources in the context of large-scale access to new energy power generation is a key issue that must be faced in the construction of a new power system.

[0004] With the rapid development of the national economy and the deepening of market-oriented reforms, the traditional "source follows load" dispatching mode of power grid control means has been almost exhausted. New loads such as electric vehicles and energy storage equipment, as well as new energy forms such as load aggregators and smart buildings are constantly emerging. It is urgent to rely on the construction of the Internet of Things, electricity markets, etc. to expand power grid control resources, innovate systems, mechanisms and technologies, and conduct in-depth research on the characteristics of various adjustable industrial loads.

[0005] However, the existing power grid regulation means are limited and the disposal means are relatively simple, mainly relying on conventional unit regulation and batch load control. Especially when dealing with power grid failures, a large number of loads need to be controlled in a short period of time, and the existing batch load control method is simple and extensive, which is easy to cause damage to equipment and other problems. At the same time, the existing industrial load resource regulation method cannot fully utilize the regulation potential on the demand side, the power grid resource optimization allocation capacity is insufficient, and the industrial load resources cannot be effectively integrated and utilized, resulting in resource waste and poor load resource regulation effect. Summary of the invention

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0041] Embodiment 1

[0042] Reference Figure 1 As shown, the present invention discloses an industrial load resource power grid interactive regulation method, comprising the following steps:

[0043] S1: Analyze the adjustable capability of the process flow during product production, and select the process that can be adjusted according to the real-time detection data on the production line without affecting the subsequent production process as the adjustable process.

[0044] In this embodiment, the adjustable process is the online annealing process. Taking the copper tube production as an example, the process of analyzing the copper tube processing flow and selecting the online annealing process as the adjustable process is described. Figure 2 The figure shows the detailed production process of copper tubes from raw materials to finished products. Multiple processing and testing steps are used to ensure the quality and performance of copper tube products.

[0045] The processing flow includes:

[0046] (1) Electrolytic copper: First, copper is produced by electrolysis, and a copper cathode plate is obtained from the electrolysis process.

[0047] (2) Melting and casting: The copper cathode plate is melted and cast into a billet.

[0048] (3) Rolling: The cast billet is rolled and further processed into the required size.

[0049] (4) Triple stretching: The stretching process is carried out through three series-connected stretching machines.

[0050] (5) Coil drawing: Further stretching processing is performed using a coil drawing machine.

[0051] (6) Horizontal winding and eddy current flaw detection: Horizontal winding is performed and an eddy current flaw detector is used to detect product quality.

[0052] (7) Annealing: During the tube making process, the copper tube will be subjected to greater stress and deformation. In order to eliminate internal stress and improve the plasticity and toughness of the copper tube, annealing is required. The annealing process includes three stages: heating, insulation and cooling. The temperature needs to be controlled during heating, and the insulation time depends on the thickness and size of the copper tube. The cooling process needs to be slow to avoid deformation and cracks of the copper tube.

[0053] (8) Internal thread forming: The internal thread of the product is processed by an internal thread forming machine.

[0054] (9) Online annealing: The material is heated, maintained at temperature, and then cooled during the continuous production process.

[0055] (10) Finished product: After testing and annealing, the final product is packaged and becomes a finished product.

[0056] Through the analysis of the above process flows (1)-(10), it can be seen that the production process of copper tubes has a series of significant characteristics, which ensure the high quality and superior performance of the final product. First, the production process uses high-purity electrolytic copper as raw material, and produces high-purity copper cathode plates by electrolysis, which ensures the purity and quality of the raw materials. Secondly, a complex and sophisticated heat treatment process is implemented in the production process, including multiple annealing and online annealing. The annealing process eliminates internal stress, improves ductility and uniform material structure through heating, maintaining temperature and slow cooling, thereby improving the mechanical properties and processing properties of the copper tube. Multiple precise inspections and controls are also carried out during the production process, such as eddy current flaw detection technology, which performs non-destructive inspections on copper tubes at multiple links to ensure the high quality and defect-free of each meter of copper tube. The horizontal winding process combined with the detection equipment is not only a forming process, but also further guarantees the product quality. In terms of mechanical processing, the production of copper tubes involves multiple stretching and rolling processes. Through triple drawing, coiling and rolling, the copper tubes are made to reach the required size and shape and given excellent mechanical properties. The internal thread forming process processes the inner wall of the copper tube according to the specific application requirements.

[0057] (1)-(8) Each process is closely linked. Once a process stops, the subsequent processes will be affected. Therefore, the power of the above processes cannot be adjusted. The online annealing process integrates the annealing process into the production line and is carried out in dedicated equipment on the continuous production line. The process can be adjusted according to the real-time detection data on the production line without affecting the subsequent production process.

[0058] Existing technologies mainly focus on the production process of electrolytic copper, but do not fully consider its regulatory potential in grid interaction. Therefore, if the copper tube plant participates in grid interaction, it can consider adjusting the power of the online annealing link, establish a coupling relationship between the adjustment power and the transmission rate, analyze the process of the copper tube plant participating in grid interaction, and provide new ideas for the effective use of flexibility resources.

[0059] S2: Calculate the power adjustable range of the adjustable process according to the process flow requirements of the adjustable process.

[0060] S2-1: During the online annealing process, the power of this process can be changed by adjusting the conveyor belt speed, so the relationship between the power of the online annealing process and the product conveyor belt speed is first constructed. Specifically, the data of the power of the online annealing process and the corresponding product conveyor belt speed are obtained, and the data is fitted by the least squares method to obtain the relationship between the power of the online annealing process and the product conveyor belt speed.

[0061] S2-1-1: The data set corresponding to the constructed data is (v1, P1), (v2, P2), ..., (v i ,P i ),...,(v n ,P n ), where P i is the power of the ith online annealing link in the data, v i P i The corresponding product conveyor belt speed, n is the total amount of data.

[0062] S2-1-2: Construct a relational model in, represents the power of the online annealing link to be fitted, v represents the product conveyor belt speed, and k and b are the fitting parameters to be determined.

[0063] S2-1-3: The objective function of the relational model is constructed, denoted as S(k,b). The calculation formula of S(k,b) is

[0064] S2-1-4: Solve the objective function to obtain the optimal solutions of k and b as k' and b', substitute the optimal solutions of k and b into the relationship model to obtain the final relationship between the power of the online annealing link and the product conveyor belt speed as P = k'v + b'.

[0065] In this embodiment, the objective function is solved to obtain the optimal solution of k and b. Specifically, the partial derivatives of k and b are obtained for the objective function respectively, and the linear equation is obtained by setting the partial derivatives to zero. The linear equation is solved to obtain the optimal solution of k and b. The result is taken as the optimal solution of k and b.

[0066] S2-2: Based on the relationship between the limited rate of the product conveyor belt speed during the product production process, the power of the online annealing link and the product conveyor belt speed, calculate the adjustable power range of the online annealing link.

[0067] The power adjustable range of the online annealing link is k'v min +b'≤P≤k'v max +b', where k' is the optimal solution for k, b' is the optimal solution for b, P is the power of the online annealing link, v min is the minimum conveyor belt speed during product production, v max It is the maximum value of the conveyor belt speed during the product production process.

[0068] S3: The real-time power of the adjustable process in the production process is adjusted in combination with the grid demand and the power adjustable range, so that the process flow of the adjustable process can achieve efficient utilization of grid load resources while meeting production demand.

[0069] Embodiment 2

[0070] The invention also discloses an industrial load resource power grid interactive regulation system, comprising an adjustable process selection module, a programmable logic controller (PLC), a dispatching center and a monitoring interface.

[0071] The adjustable process selection module analyzes the adjustable capability of the process flow during product production, and selects the process that can be adjusted according to the real-time detection data on the production line without affecting the subsequent production process as the adjustable process.

[0072] The programmable logic controller calculates the power adjustable range of the adjustable process according to the process flow requirements of the adjustable process; and adjusts the real-time power of the adjustable process in the production process in combination with the grid demand and the power adjustable range, so that the process flow of the adjustable process can achieve efficient utilization of grid load resources while meeting the production requirements.

[0073] like Figure 3As shown, taking copper tube production as an example, the copper tube factory uploads the real-time power and conveyor belt transmission rate of the online annealing link to the PLC, and the adjustable process is the online annealing link. The programmable logic controller obtains the power of the online annealing link and the corresponding product conveyor belt rate in real time, and fits the real-time acquired data through the least squares method to obtain the relationship between the power of the online annealing link and the product conveyor belt rate. Combined with the maximum and minimum values ​​of the product conveyor belt rate, the power adjustable range of the online annealing link is calculated to obtain the upper limit of the adjustable power Pmax=k'v max +b', lower limit Pmin = k'v min +b', and upload it to the dispatching center; the dispatching center sends the power regulation demand within the power adjustable range to the programmable logic controller according to the power grid demand; the programmable logic controller obtains the speed regulation demand of the product conveyor belt based on the received power regulation demand, the power of the online annealing link and the relationship between the speed of the product conveyor belt, and adjusts the speed of the product conveyor belt in real time according to the speed regulation demand, thereby changing the power of the online annealing link, thereby completing the response to the power grid dispatching instruction.

[0074] Specifically, the interface logic of the speed adjustment command for the speed of the product conveyor belt is as follows: Figure 4 As shown, the field interface of the programmable logic controller sends the production line speed setting, real-time speed, feed length, annealing length, and receives the negative control auxiliary speed setting (speed deviation instruction); the total production line speed setting is calculated in combination with the production line speed setting and the negative control auxiliary speed setting (in this embodiment, the total production line speed setting = production line speed setting + negative control auxiliary speed setting), and the total production line speed setting is sent to the production line drag motor driver, and the production line load response is achieved by adjusting the production line speed. The programmable logic controller receives real-time information of each production line in the product production process (product specifications, feed length, actual length of online annealing, actual value of production line speed, production line speed setting, negative control speed setting, total production line speed setting) and automatically calculates the current adjustable online annealing link power of each production line. After the grid dispatcher inquires about the current adjustable capacity of the copper tube factory, it can issue appropriate load dispatching instructions to the copper tube factory. When the copper tube factory receives the grid dispatching instruction, it first sets the grid load dispatching instruction (power / current) on the monitoring interface. The load control device automatically calculates the auxiliary speed setting of the production line according to the instruction and the current adjustable capacity of the production line, and distributes it to each online annealing production line. After each online annealing production line receives the negative control speed setting, it superimposes the negative control speed setting on the production line speed setting to obtain the total production line speed setting, and sends the total production line speed setting to the production line drag motor driver.

[0075] The monitoring interface is used to display the real-time data of the adjustable process in the product production process, the power grid load control settings and the power grid load control status. The real-time data of the adjustable process includes product specifications, feed length, actual length of online annealing, actual value of production line speed, production line speed setting, negative control speed setting, total production line speed setting, and online annealing power. The power grid load control setting includes power grid load dispatching (power / current) instructions, production line speed auxiliary setting, and load dispatching instruction locking. The power grid load control status includes the start time of load control execution, the time when load control has been executed, the adjustment power of the adjustable process corresponding to the load control, and the power adjustment range of the current adjustable process.

[0076] Embodiment 3

[0077] The present invention also discloses a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the industrial load resource power grid interactive regulation method in the first embodiment is implemented.

[0078] Embodiment 4

[0079] The present invention also discloses an industrial load resource power grid interactive regulation device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the industrial load resource power grid interactive regulation method in Embodiment 1 when executing the computer program.

[0080] The traditional power system mainly relies on the power generation side to adjust the load resources, and the adjustment capacity is limited, and it fails to fully utilize the adjustment potential on the demand side. In particular, the online annealing link in the copper tube production has the adjustment capacity, but it is not used. In the face of the volatility of new energy power generation, there is insufficient flexibility. The existing adjustment means are single and insufficient, and it is difficult to cope with the complex grid adjustment needs, especially when dealing with grid failures. The existing means are prone to have a negative impact on production. In addition, the existing grid resource optimization and allocation capabilities are insufficient, the resource allocation efficiency is low, and various industrial load resources have not been effectively integrated and utilized, resulting in resource waste and poor adjustment effects.

[0081] The present invention analyzes the adjustable capacity of the process flow in the product production process, selects the process with adjustment potential in the grid interaction as the adjustable process and calculates the corresponding power adjustable range, thereby realizing a comprehensive analysis and evaluation of various resources on the demand side, allowing the adjustable resources to participate in the grid interaction, thereby improving the grid's ability to optimize resource allocation, security assurance and intelligent interaction capabilities; on this basis, the real-time power of the adjustable process in the production process is adjusted in combination with the grid demand and the power adjustable range, so that the process flow of the adjustable process can achieve efficient and accurate utilization of grid load resources while meeting production needs.

[0082] Furthermore, the present invention takes copper tube production as an example, and through detailed analysis of the copper tube production process, determines that the online annealing link is an adjustable process, and realizes the effective utilization of demand-side resources by studying the adjustment potential of the online annealing link; the adjustment of the online annealing link can be carried out without affecting the production process, so as to achieve the coordination of power grid regulation and production process, and avoid the negative impact of traditional adjustment means on production. By establishing a coupling relationship between the power and transmission rate of the online annealing link, precise regulation is achieved, the system adjustment capability is enhanced, and the adjustment efficiency and utilization rate of industrial load resources are improved; the power output is flexibly adjusted according to the power grid demand, and the adaptability of the power grid to the volatility of new energy power generation is enhanced, especially when dealing with the volatility of new energy power generation. Through the intelligent interaction and optimized configuration of the present invention, the safety assurance capability of the power grid can also be improved, especially when dealing with faults, it can respond and adjust quickly to ensure the stable operation of the power grid.
