[0002] When a factory manufactures vehicles, it usually includes multiple high-energy consumption production links such as sheet metal rolling, structural welding, and production assembly. Changes in the production process of each high-energy consumption production link will have a certain impact on the power grid system. In order to meet the needs of power grid scheduling and peak load regulation, each production link of the factory can be controlled.

[0003] In the related art, the factory staff usually manually dispatches the various production links of the factory based on their operating experience to make it meet the peak load requirements of the power grid system. However, the manual dispatch of the various production links of the factory is limited by factors such as whether the experience is rich, whether the peak load instructions of the power grid are drastic, and whether the factory's own operation is normal, resulting in low accuracy in the operation control of the factory's production links.

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The operation control method of the production link provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the first server 102 communicates with the second server 104 through the network. The first server 102 is a server of the power grid system, and the second server 104 is a server of the target factory. The data storage system can store the data that the second server 104 needs to process. The data storage system can be integrated on the second server 104, or it can be placed on the cloud or other network servers.

[0050] The first server 102 can send a power grid peak-shaving instruction to the second server 104. In response to the power grid peak-shaving instruction sent by the power grid system, the second server 104 determines the peak-shaving demand information of the target factory, and the peak-shaving demand information is used to indicate the peak-shaving energy supply power of the power grid system. Subsequently, the second server 104 adjusts the power generation power of the self-generation system of the target factory according to the peak-shaving energy supply power. If the maximum power generation power of the self-generation system is less than the power to be compensated, the second server 104 determines the energy consumption supply missing power of the target factory based on the energy consumption power of the target factory, the peak-shaving energy supply power and the power generation power of the self-generation system. The power to be compensated is the energy supply gap caused by the change of the peak-shaving energy supply power. Finally, the second server 104 adjusts the operating status of each production link step by step according to the energy consumption supply missing power.

[0051] The first server 102 and the second server 104 may be independent physical servers, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0052] In an exemplary embodiment, Figure 2 As shown, a production process operation control method is provided, and the method is applied to Figure 1 The second server in the example is used as an example, including S201-S204:

[0053] S201. In response to a grid peak-shaving instruction sent by a grid system, determine peak-shaving demand information of a target plant, where the peak-shaving demand information is used to indicate a peak-shaving energy supply power of the grid system.

[0054] In the present application, the first server of the external power grid system can send a power grid peak-shaving instruction to the second server of the target factory, thereby indicating the power peak-shaving information of the power grid system, so that the second server can perform preliminary calculations based on the power peak-shaving information of the power grid system and determine the peak-shaving demand information of the target factory.

[0055] The peak-shaving demand information is used to indicate the peak-shaving energy supply power of the power grid system. The peak-shaving energy supply power of the power grid system may be the power of electric energy provided by the power grid system to the target factory based on peak-shaving scheduling. The peak-shaving energy supply power of the power grid system may change dynamically over time.

[0056] It should be understood that the embodiments of the present application do not limit the target factory, and it can be an automobile factory, steel factory, or other factory with high-energy-consuming production links.

[0057] In some real-time embodiments, the peak load power of the power grid system can be determined by a power grid power variation model. The power grid power variation model determines the peak load power of the power grid system by the peak load initial power of the power grid system, the power grid peak load variation time and the power grid peak load variation rate.

[0058] Exemplarily, the power grid variation model may be as shown in formula (1):

[0059]

[0060] Among them, A gri P is the peak-shaving change rate of the power grid, which is used to indicate the speed of change of the peak-shaving of the power grid, so as to judge whether the speed of increase and decrease of the self-generated power of the target factory can meet the continuous production index of the target factory; gri,reg It is the peak-shaving power supply of the power grid system, and is used to determine whether the target plant's self-generated power output can compensate for the peak-shaving situation of the power grid; P gri,ini is the initial peak load of the power grid system; τ gri It is the peak load variation time of the power grid.

[0061] It should be understood that the peak-shaving power supply power of the power grid system determined by the above-mentioned power grid power variation model can be the peak-shaving power supply power at any subsequent time. That is, if the peak-shaving power supply of the power grid reduces the available energy consumption of the target factory, the available energy consumption may also increase after a period of time in the future. Therefore, through the peak-shaving power supply power of the power grid system, it can be predicted in advance whether the production preheating unit should be started in advance, so that after the load that the power grid can provide is restored, the production preparation equipment can be directly put into production.

[0062] S202: Adjust the power generation power of the self-generation system of the target factory according to the peak-shaving energy supply power.

[0063] In this step, when the peak-shaving energy supply power of the second server power grid system is reached, the power generation power of the self-generation system of the target factory can be adjusted according to the peak-shaving energy supply power.

[0064] It should be understood that in the actual production process, the main sources of electricity for the target factory are the power grid system and the self-generation system. Accordingly, on the power supply side, the target factory can set up two power supply sources: the external power grid system and the factory self-generation system. When the power generation power of the power grid system changes due to peak load regulation, the power generation power of the self-generation system of the target factory can be adjusted accordingly.

[0065] In some embodiments, the second server may increase or decrease the power generated by the self-generating system accordingly based on the change in the peak-shaving power supply, thereby maintaining the total power supply unchanged.

[0066] In some embodiments, if the maximum power generation of the self-generating system is greater than or equal to the power to be compensated, the operating status of each production link may not be adjusted, and the power to be compensated is the energy supply gap caused by the change in the peak-shaving energy supply power. If the maximum power generation of the self-generating system is less than the power to be compensated, the target factory's energy consumption supply missing power can be determined to adjust the operating status of each production link. That is, the maximum power generation that can be achieved by the unit of the self-generating system is sufficient to compensate for the power shortage of the power grid system, and the production process of the factory does not need to be adjusted too much. If the maximum power generation that can be achieved by the unit of the self-generating system is not enough to compensate for the shortage of power in the power grid, the operating status of each production link needs to be adjusted.

[0067] In some embodiments, if the maximum power generation of the self-generating system is less than the power to be compensated, the second server may also obtain the initial power supply information of the self-generating system and the production process information of the target factory. Subsequently, the second server determines the non-essential power change rate of the target factory based on the initial power supply information and the production process information of the self-generating system.

[0068] The production process information may be the power that can be delayed or temporarily cancelled in the production process.

[0069] Exemplarily, the calculation of the non-essential power variation rate of the target plant can be shown as formula (2):

[0070]

[0071] Among them, A none,iro is the non-essential power change rate of the target plant, P sta,ini is the initial power supply of the target factory’s self-generation system, P gri,ini is the initial peak load power, ΔP off It is the production process information of the target factory.

[0072] If the maximum power generation of the self-generating system is less than the power to be compensated, the second server can obtain the initial power supply information of the self-generating system and the production process information of the target factory. Then, the second server determines the non-essential power change rate of the target factory based on the initial power supply information and the production process information of the self-generating system.

[0073] In the present application, by calculating the non-essential power variation rate of the target factory, it is possible to assist in determining the adjustability of each production link, thereby improving the accuracy of the operation control of the production link.

[0074] S203: If the maximum power generation of the self-generation system is less than the power to be compensated, the energy consumption supply missing power of the target plant is determined according to the energy consumption power of the target plant, the peak load supply power and the power generation power of the self-generation system.

[0075] In this step, when the second server determines to adjust the power generation power of the self-generation system of the target factory according to the peak-shaving energy supply power, if the maximum power generation power of the self-generation system is less than the power to be compensated, the energy consumption supply missing power of the target factory is determined according to the energy consumption power of the target factory, the peak-shaving energy supply power and the power generation power of the self-generation system.

[0076] Among them, the power to be compensated is the energy supply gap caused by the change of peak energy supply power.

[0077] In some embodiments, the energy consumption power of the target factory can be pre-configured to the second server, and the power generated by the self-generation system can be obtained by the second server in real time from the self-generation system.

[0078] It should be noted that since the maximum power generation of the self-generation system is less than the power to be compensated, that is, the maximum power generation of the self-generation system of the target plant is not enough to make up for the power loss of the power grid, the power generation of the self-generation system should not be lower than the maximum power generation.

[0079] Exemplarily, the target plant's energy consumption supply missing power can be determined by subtracting the target plant's energy consumption power from the power generated by the self-generation system and then subtracting the peak-shaving power supply power. The target plant's energy consumption supply missing power can be calculated as shown in formula (3):

[0080] ΔP def =P use -P sta,reg -P gri,reg (3)

[0081] Among them, ΔP def Supply the missing power for the target plant’s energy consumption, P use is the energy consumption of the target factory, P sta,reg is the power generated by the self-generating system, P gri,regProvide energy for peak load regulation.

[0082] S204, supplying missing power according to energy consumption, and adjusting the operating status of each production link step by step.

[0083] In this step, after the energy consumption supply missing power is determined, the operating status of each production link can be adjusted step by step according to the energy consumption supply missing power.

[0084] In some embodiments, the production process of vehicle manufacturing can be divided into a production overlapping process in which multiple production lines are produced in parallel, a production continuity process with time continuity requirements, and a production preparation process for startup preparation and equipment preheating required before the equipment is started. Therefore, on the load side, three production processes for power load exports with different scheduling levels can be set: a production overlapping process, a production continuity process, and a production preparation process.

[0085] In some embodiments, the adjustment priority of the production preparation link is higher than the production superposition link, and the adjustment priority of the production superposition link is higher than the production continuity link. That is, when the power supply is insufficient, the production preparation link can be shut down first, then the production superposition link, and finally the production continuity link.

[0086] It should be understood that the embodiments of the present application do not limit how to adjust the operating status of each production link step by step according to the missing power of energy consumption supply. In some embodiments, the second server can control at least one production preparation link to be adjusted to a shutdown state, and determine the first energy consumption supply difference based on the power released by the at least one production preparation link that is shut down and the missing power of energy consumption supply. If the first energy consumption supply difference is less than or equal to zero, stop adjusting the operating status of the production overlapping link and the production continuous link. If the first energy consumption supply difference is greater than zero, adjust the operating status of the production overlapping link.

[0087] The first energy consumption supply difference may be the energy consumption supply difference after closing at least one production preparation link.

[0088] Exemplarily, after shutting down at least one production preparation link, the calculation formula of the first energy consumption supply difference can be shown as formula (4):

[0089]

[0090] Among them, ΔP def,st1 is the first energy consumption supply difference, P pre,i The power released to shut down the i-th production preparation link, ΔP def Provides missing power for energy consumption.

[0091] For example, when i production preparation links are shut down, the power quota released allows the remaining production to continue, that is, after shutting down i production preparation links, ΔP def,st1 When ≤0, the remaining ni production preparation links do not need to be shut down, and the remaining production mixing links and production continuous links can also operate normally, and the optimal control is completed.

[0092] For example, when the power released after shutting down i production preparation links cannot make ΔP def,st1 ≤0, continue to shut down the remaining production preparation links until n production preparation links are shut down ΔP def,st1 >0, first shut down all the production preparation links, and consider adjusting the operating status of the production mixing link.

[0093] In some embodiments, when only regulating the production preparation link cannot meet the requirements of the energy consumption supply difference, at least one production overlapping link can be controlled to be adjusted to a shutdown state, and the second energy consumption supply difference is determined according to the power released by the at least one production overlapping link that is shut down and the first energy consumption supply difference. If the second energy consumption supply difference is less than or equal to zero, the operation state of the production continuous link is stopped from being adjusted. If the second energy consumption supply difference is greater than zero, the operation state of the production continuous link is adjusted.

[0094] The second energy consumption supply difference may be the energy consumption supply difference after closing at least one production mixing link.

[0095] It should be noted that in the actual production process of the target factory, the overlapping production process cannot be completely shut down. If the overlapping production process is completely shut down, it may cause confusion in the production process of the target factory until the conventional operation logic is broken. Therefore, some overlapping operation energy consumption required to ensure the normal production of the target factory should be provided. Based on this, the guaranteed operation quantity threshold of the production overlapping link can be specifically set based on the actual situation, and the embodiments of the present application do not limit this.

[0096] Exemplarily, among a total of o overlapping and mixing links, the guaranteed operation quantity threshold of the production overlapping and mixing links is x, that is, x units should be put into guaranteed operation and cannot be shut down. Therefore, the number of closed overlapping and mixing links should not be greater than ox.

[0097] Exemplarily, after shutting down at least one production stacking link, the calculation formula for the second energy consumption supply difference can be shown as formula (5):

[0098]

[0099] Among them, ΔP def,st2 is the second energy consumption supply difference, P pre,i The power released to shut down the i-th production preparation link, P mix,jThe power released by shutting down the jth production mixing link, ΔP def Provides missing power for energy consumption.

[0100] For example, when all production preparation links are shut down and j production overlapping links are shut down at the same time, the power quota released allows the remaining production overlapping links to continue, that is, after shutting down j production overlapping links, ΔP def,st2 When ≤0, the remaining oxj devices do not need to be shut down, and the remaining devices can also operate normally, and the optimal control is completed.

[0101] For example, when j production overlapping links are shut down, the power released cannot make ΔP def,st2 ≤0, then continue to shut down other production mixing links until ox production preparation links are shut down ΔP def,st2 If it is still greater than 0, x production overlapping links will continue to operate to provide production guarantee, and then the operating status of the continuous production links will be adjusted to adapt to the grid load as much as possible.

[0102] In some embodiments, when only regulating the production preparation link and the production overlapping link cannot meet the requirements of the energy consumption supply difference, the operating state of the production continuity link can be adjusted. The second server can first obtain the configuration information of the production continuity link, and the configuration information includes the maximum variation coefficient of the production continuity link, the peak-shaving variation coefficient adapted to the power grid system, and the power variation coefficient adapted to the production continuity link. Subsequently, the second server can determine the power adjustment coefficient of the production continuity link based on the maximum variation coefficient of the production continuity link, the peak-shaving variation coefficient adapted to the power grid system, and the power variation coefficient adapted to the production continuity link. Finally, the second server can adjust the operating state of the production continuity link based on the power adjustment coefficient of the production continuity link, the power of the production continuity link, and the second energy consumption supply difference.

[0103] In some embodiments, the above configuration information can be pre-configured in a specific storage location of the second server, and when adjustments to the production continuity link are required, the second server can obtain the above configuration information from the specific storage location.

[0104] For example, the calculation formula of the power adjustment coefficient of the continuous production link can be shown as formula (6):

[0105] ω=bA gri ·cA con,max (6)

[0106] Among them, ω is the power adjustment coefficient of the continuous production link, b is the peak load change rate coefficient of the power grid system, c is the power change coefficient of the continuous production link, A cpn,max In order to control the maximum coefficient of variation allowed in the continuous production process, Agri is the peak load variation rate of the power grid.

[0107] For example, the second server can obtain the third energy consumption supply difference according to the power adjustment coefficient of the continuous production link, the power of the continuous production link and the second energy consumption supply difference, that is, the energy consumption supply difference after adjusting the continuous production link. By making the third energy consumption supply difference as small as possible and equal to 0, the production speed of the continuous link is adjusted to adapt to the peak load requirements of the external power grid and the maximum power generation output of the factory's self-generation system.

[0108] Exemplarily, the calculation formula for the third energy consumption supply difference may be as shown in formula (7):

[0109]

[0110] Among them, ΔP def,st3 is the third energy consumption supply difference, P pre,i The power released to shut down the i-th production preparation link, P mix,j The power released by shutting down the jth production mixing link, ΔP def is the missing power for energy consumption, ω is the power adjustment coefficient for continuous production, P com The power of continuous production process.

[0111] In some embodiments, when regulating the continuous links, the maximum coefficient of variation allowed in the continuous production links can be established, that is, the maximum rate allowed for adjustment. In the continuous production link, the change in production speed has a delay, and the continuous links are closely arranged, and some strict processes may not allow adjustment. Therefore, the maximum coefficient of variation allowed in the continuous production link can be established based on the actual equipment operation and production conditions of the factory. In addition, in order to reduce the delay of continuous production and the possible mixing between processes, the value of the maximum coefficient of variation allowed in the continuous production link can be less than or equal to 0.2.

[0112] In some embodiments, the power variation coefficient c adapted to the continuous production link can be set based on the maximum variation coefficient allowed by the continuous production link. If the fastest adjustment is required, the c value can be set to 1, and the remaining adjustments can be appropriately changed according to the operation of the factory equipment. Under the premise of ensuring adaptation to external load changes, the c value should be as small as possible, and the minimum value of c can be 0.

[0113] In some embodiments, the peak load variation rate A of the power grid can be gri Match and adapt to the peak load change rate coefficient b of the power grid system. When the actual operating conditions of the factory allow, the maximum value of b is 0.1 and not less than 0.

[0114] In some embodiments, the values ​​of the peak-shaving variation coefficient b of the power grid system and the power variation coefficient c of the production continuity link can be adjusted to ensure that the production continuity link adapts to the external power grid load changes as much as possible without interrupting production continuity.

[0115] In this application, when adjusting the operating status of each production link step by step to adapt to the peak-shaving requirements of the external power grid, the production preparation link, the production overlapping link, and the production continuity link are taken into consideration. In addition, according to the peak-shaving requirements of the power grid, the self-generated power output of the factory is reasonably called, driven by the peak-shaving of the power grid. In the production preparation link, the production overlapping link, and the production continuity link, the mixed effect between the power released by the regulation and the power supplied by the power grid is considered, providing a more accurate regulation strategy for the actual power regulation of the target factory.

[0116] The operation control method of the production link provided in the embodiment of the present application, first, in response to the grid peak-shaving instruction sent by the grid system, the peak-shaving demand information of the target factory is determined, and the peak-shaving demand information is used to indicate the peak-shaving energy supply power of the grid system. Subsequently, according to the peak-shaving energy supply power, the power generation power of the self-generation system of the target factory is adjusted. If the maximum power generation power of the self-generation system is less than the power to be compensated, the energy consumption supply missing power of the target factory is determined according to the energy consumption power of the target factory, the peak-shaving energy supply power and the power generation power of the self-generation system, and the power to be compensated is the energy supply gap generated when the peak-shaving energy supply power changes. Finally, according to the energy consumption supply missing power, the operation status of each production link is adjusted step by step. Since the power generation power of the self-generation system of the target factory is adjusted according to the peak-shaving energy supply power, and the operation status of each production link is adjusted step by step according to the energy consumption supply missing power, it is possible to perform dynamic adjustment and hybrid control based on the production characteristics of production links at different levels, thereby improving the accuracy of the operation control of the production links of the factory.
