[0048] In order to make the purposes, technical solutions and advantages of the present application clearer, further detailed description will be given below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.
[0049] The production link operation control method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . The first server 102 communicates with the second server 104 through a network. The first server 102 is a server of a power grid system, and the second server 104 is a server of a target factory. A data storage system can store data required to be processed by the second server 104. The data storage system can be integrated on the second server 104, or placed on a cloud or other network server.
[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 peak shaving demand information of the target factory, which is used to indicate a peak shaving power supply power of the power grid system. Then, the second server 104 adjusts a power generation power of a self-power generation system of the target factory according to the peak shaving power supply power. If the maximum power generation power of the self-power generation system is less than a to-be-compensated power, the second server 104 determines an energy consumption supply missing power of the target factory according to an energy consumption power of the target factory, the peak shaving power supply power and the power generation power of the self-power generation system, the to-be-compensated power being an energy supply gap generated when the peak shaving power supply power changes. Finally, the second server 104 adjusts operation states of various production links in stages according to the energy consumption supply missing power.
[0051] The first server 102 and the second server 104 can be independent physical servers, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.
[0052] In an exemplary embodiment, as shown in Figure 2 , a production link operation control method is provided. Taking the second server in Figure 1 as an example, the method includes S201-S204:
[0053] S201, in response to a power grid peak shaving instruction sent by a power grid system, determining peak shaving demand information of a target factory, the peak shaving demand information being used to indicate a peak shaving power supply power of the power 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, so as to instruct the power peak shaving information of the power grid system, so that the second server performs preliminary calculation based on the power peak shaving information of the power grid system to determine the peak shaving demand information of the target factory.
[0055] The peak shaving demand information is used to indicate the peak shaving power supply power of the power grid system. The peak shaving power supply power of the power grid system can be the power of the power supply provided by the power grid system to the target factory based on the peak shaving scheduling. The peak shaving power supply power of the power grid system can dynamically change over time.
[0056] It should be understood that the embodiments of the present application do not limit the target factory, which can be a car factory, a steel factory, etc. with high energy-consuming production links.
[0057] In some real-time embodiments, the peak shaving power supply 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 shaving power supply power of the power grid system through the peak shaving initial power of the power grid system, the power grid peak shaving change time and the power grid peak shaving variation rate.
[0058] For example, the power grid power variation model can be as shown in formula (1):
[0059]
[0060] wherein A gri is the power grid peak shaving variation rate, which is used to indicate the change speed of the power grid peak shaving, so as to determine whether the increase or decrease of the self-generation of the target factory meets the index of continuous production of the target factory; P gri,reg is the peak shaving power supply power of the power grid system, which is used to determine whether the power output of the self-generation of the target factory can compensate for the power grid peak shaving; P gri,ini is the peak shaving initial power of the power grid system; τ gri is the power grid peak shaving change time.
[0061] It should be understood that the peak shaving power supply power of the power grid system determined by the above power grid power variation model can be the peak shaving power supply power at any subsequent time. That is, if the power grid peak shaving reduces the available energy consumption of the target factory, but the available energy consumption can 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 determined in advance whether the production preheating unit should be started in advance, so that the production preparation equipment can be directly put into production after the load recovery provided by the power grid.
[0062] S202, adjusting the power generation power of the self-generation system of the target factory according to the peak shaving power supply power.
[0063] In this step, when the peak-shaving power supply of the second server grid system, the power generation of the self-power generation system of the target factory can be adjusted according to the peak-shaving power supply.
[0064] It should be understood that in the actual production process, the main power source of the target factory is the grid system and the self-power generation system. Accordingly, on the power supply side, the target factory can set two power supply sources, the external grid system and the self-power generation system of the factory. When the power generation of the grid system changes due to peak shaving, the power generation of the self-power generation system of the target factory can be adjusted accordingly.
[0065] In some embodiments, the second server can increase or decrease the power generation of the self-power generation system based on the change amount of the peak-shaving power supply, so as to maintain the total power supply unchanged.
[0066] In some embodiments, if the maximum power generation of the self-power generation system is greater than or equal to the to-be-compensated power, the operation state of each production process can not be adjusted, and the to-be-compensated power is the power supply gap generated when the peak-shaving power supply changes. If the maximum power generation of the self-power generation system is less than the to-be-compensated power, the energy supply deficiency power of the target factory can be determined to adjust the operation state of each production process. That is, the maximum power generation of the unit of the self-power generation system is sufficient to compensate for the power shortage of the grid system, and the production process of the factory does not need to be adjusted too much. The maximum power generation of the unit of the self-power generation system is insufficient to compensate for the power shortage of the grid, and the operation state of each production process needs to be adjusted.
[0067] In some embodiments, if the maximum power generation of the self-power generation system is less than the to-be-compensated power, the second server can also obtain the initial power supply information of the self-power generation system and the production process information of the target factory. Subsequently, the second server can determine the non-essential power variation rate of the target factory according to the initial power supply information of the self-power generation system and the production process information.
[0068] The production process information can be the power that can be delayed or temporarily cancelled in the production process.
[0069] For example, the calculation of the non-essential power variation rate of the target factory can be shown in formula (2):
[0070]
[0071] Wherein, A none,iro is the non-essential power variation rate of the target factory, P sta,ini is the initial power supply of the self-power generation system of the target factory, P gri,ini is the initial power of the peak shaving, ΔP off is the production process information of the target factory.
[0072] If the maximum power generation of the self-power generation system is less than the power to be compensated, the second server can acquire initial energy supply information of the self-power generation system and production process information of the target factory. Then, the second server determines the non-essential power variation rate of the target factory according to the initial energy supply information of the self-power generation system and the production process information.
[0073] In the present application, by calculating the non-essential power variation rate of the target factory, the adjustable degree of each production link can be assisted to be judged, thereby improving the accuracy of operation control of the production link.
[0074] S203, if the maximum power generation of the self-power generation system is less than the power to be compensated, the energy supply deficiency power of the target factory is determined according to the energy consumption power of the target factory, the peak regulation energy supply power and the power generation of the self-power generation system.
[0075] In this step, after the second server determines that the power generation of the self-power generation system of the target factory is adjusted according to the peak regulation energy supply power, if the maximum power generation of the self-power generation system is less than the power to be compensated, the energy supply deficiency power of the target factory is determined according to the energy consumption power of the target factory, the peak regulation energy supply power and the power generation of the self-power generation system.
[0076] Wherein, the power to be compensated is the energy supply gap generated when the peak regulation energy supply power changes.
[0077] In some embodiments, the energy consumption power of the target factory described above can be pre-configured to the second server, and the power generation of the self-power generation system described above can be acquired by the second server from the self-power generation system in real time.
[0078] It should be noted that, since the maximum power generation of the self-power generation system is less than the power to be compensated, that is, the maximum power generation of the self-power generation system of the target factory is insufficient to make up for the power grid power deficiency. At this time, the power generation of the self-power generation system should not be lower than the maximum power generation.
[0079] For example, the energy supply deficiency power of the target factory can be determined by subtracting the power generation of the self-power generation system from the energy consumption power of the target factory, and then subtracting the peak regulation energy supply power. The calculation of the energy supply deficiency power of the target factory can be shown as formula (3):
[0080] ΔP def = P use -P sta,reg -P gri,reg (3)
[0081] Wherein, ΔP def is the energy supply deficiency power of the target factory, P use is the energy consumption power of the target factory, P sta,reg is the power generation of the self-power generation system, and P gri,regTo adjust the peak power supply.
[0082] S204, according to the energy supply missing power, adjust the running state of each production link step by step.
[0083] In this step, when the energy supply missing power is determined, the running state of each production link can be adjusted step by step according to the energy supply missing power.
[0084] In some embodiments, the production link of vehicle manufacturing can be divided into a production mixed link produced in parallel by multiple production lines, a production continuous link with time continuity requirement, and a production preparation link requiring start preparation and equipment preheating before equipment start. Therefore, on the load side, the production link of the power load outlet of three different scheduling levels of production mixed link, production continuous link and production preparation link can be set.
[0085] In some embodiments, the adjustment priority of the production preparation link is higher than that of the production mixed link, and the adjustment priority of the production mixed link is higher than that of the production continuous link. That is, when the power supply is insufficient, the production preparation link can be closed first, then the production mixed link, and finally the production continuous link.
[0086] It should be understood that the embodiments of the present application do not limit how to adjust the running state of each production link step by step according to the energy supply missing power. In some embodiments, the second server can control at least one production preparation link to adjust to the shutdown state, and determine the first energy supply difference according to the power released by the at least one production preparation link shut down and the energy supply missing power. If the first energy supply difference is less than or equal to zero, the adjustment of the running state of the production mixed link and the production continuous link is stopped. If the first energy supply difference is greater than zero, the running state of the production mixed link is adjusted.
[0087] Wherein, the first energy supply difference can be the energy supply difference after the at least one production preparation link is closed.
[0088] For example, after the at least one production preparation link is shut down, the calculation formula of the first energy supply difference can be shown in formula (4):
[0089]
[0090] Wherein, ΔP def,st1 is the first energy supply difference, P pre,i is the power released by the i th production preparation link shut down, ΔP def is the energy supply missing power.
[0091] For example, when i production preparation links are shut down, the released power enables the remaining production to continue, that is, when i production preparation links are shut down, ΔP def,st1 ≤ 0, the remaining n-i 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 released power after shutting down i production preparation links cannot enable ΔP def,st1 ≤ 0, the remaining production preparation links are continuously shut down until n production preparation links are shut down, and ΔP def,st1 > 0, all production preparation links are shut down, and the operating state of the production mixing links is adjusted.
[0093] In some embodiments, when the adjustment of the production preparation links cannot meet the requirement of the energy supply difference, at least one production mixing link is controlled to be in a shut-down state, and a second energy supply difference is determined according to the released power of the shut-down at least one production mixing link and the first energy supply difference. If the second energy supply difference is less than or equal to zero, the adjustment of the operating state of the production continuous link is stopped. If the second energy supply difference is greater than zero, the adjustment of the operating state of the production continuous link is performed.
[0094] The second energy supply difference can be the energy supply difference after the at least one production mixing link is shut down.
[0095] It should be noted that in the actual production links of the target factory, the production mixing links cannot be completely shut down, and if the production mixing links are completely shut down, the production process of the target factory can be chaotic until the conventional operation logic is broken. Therefore, some production mixing links that guarantee normal production of the target factory should be provided. Based on this, the guarantee running number threshold of the production mixing links can be set based on the actual situation, and the embodiments of the present application do not limit this.
[0096] For example, among the total o production mixing links, the guarantee running number threshold of the production mixing links is x, that is, x production mixing links should be put into guarantee running and cannot be shut down, and therefore, the number of shut-down production mixing links should be less than or equal to o-x.
[0097] For example, after at least one production mixing link is shut down, the calculation formula of the second energy supply difference can be as shown in formula (5):
[0098]
[0099] wherein, ΔP def,st2 is the second energy supply difference, P pre,i is the released power of the i-th production preparation link, and P mix,jThe power released when the jth production stack is shut down, ΔP def is the power supplied by the energy consumption.
[0100] For example, when all production preparation links are shut down and j production stacks are shut down, the amount of power released allows the remaining production stacks to continue to operate, that is, ΔP def,st2 ≤ 0, the remaining o-x-j 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 the power released after j production stacks are shut down cannot make ΔP def,st2 ≤ 0, other production stacks continue to be shut down until o-x production preparation links are shut down, and ΔP def,st2 is still greater than 0, and x production stacks continue to operate to provide production guarantee, and then the operating state of the production continuous link is adjusted to adapt to the power grid load as much as possible.
[0102] In some embodiments, when the production preparation links and the production stacks cannot meet the requirement of the energy consumption supply difference, the operating state of the production continuous link can be adjusted. The second server can first obtain configuration information of the production continuous link, which includes a maximum variation coefficient of the production continuous link, a peak regulation variation rate coefficient adapted to the power grid system, and a power variation coefficient adapted to the production continuous link. Then, the second server can determine a power adjustment coefficient of the production continuous link according to the maximum variation coefficient of the production continuous link, the peak regulation variation rate coefficient adapted to the power grid system, and the power variation coefficient adapted to the production continuous link. Finally, the second server can adjust the operating state of the production continuous link according to the power adjustment coefficient of the production continuous link, the power of the production continuous link, and the second energy consumption supply difference.
[0103] In some embodiments, the above configuration information can be preconfigured in a specific storage location of the second server, and when the production continuous link needs to be adjusted, 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 production continuous link can be as shown in formula (6):
[0105] ω = bA gri · cA con,max (6)
[0106] where ω is the power adjustment coefficient of the production continuous link, b is the peak regulation variation rate coefficient adapted to the power grid system, c is the power variation coefficient adapted to the production continuous link, A cpn,max is the maximum variation coefficient allowed for regulating the production continuous link, and Agri a power variation rate of the grid.
[0107] For example, the second server can obtain a third energy supply difference, i.e., an energy supply difference after adjusting the production of the continuous link, according to the power adjustment coefficient of the production continuous link, the power of the production continuous link, and the second energy supply difference. By making the third energy supply difference as small as possible and equal to or less than 0, the production speed of the continuous link is adjusted to adapt to the peak shaving requirement of the external grid and the maximum power generation output of the self-power generation system of the factory.
[0108] For example, the calculation formula of the third energy supply difference can be as shown in formula (7):
[0109]
[0110] wherein, ΔP def,st3 is the third energy supply difference, P pre,i is the released power of the i th production preparation link, P mix,j is the released power of the j th production mixing link, ΔP def is the energy supply missing power, ω is the power adjustment coefficient of the production continuous link, P com is the power of the production continuous link.
[0111] In some embodiments, when the continuous link is regulated, the maximum variation coefficient allowed by the production continuous link, i.e., the maximum rate allowed by the adjustment, can be established. In the continuous production link, the variation of the production speed has a delay, and the continuous links are arranged closely, and some strict processes can not be allowed to be adjusted, so the above-mentioned maximum variation coefficient allowed by the production continuous link can be established based on the actual equipment operation and production situation of the factory. In addition, in order to reduce the delay of the continuous production and the mixing that can exist between processes, the numerical value of the maximum variation coefficient allowed by the production continuous link can be less than or equal to 0.2.
[0112] In some embodiments, the power variation coefficient c adapted to the production continuous link can be set based on the maximum variation coefficient allowed by the production continuous link. If the most rapid adjustment is required, the value of c can be set to 1, and the rest of the adjustment can be appropriately changed according to the operation situation of the equipment of the factory. On the premise of ensuring the adaptation to the external load variation, the value of c should be as small as possible, and the minimum value of c can be 0.
[0113] In some embodiments, the power variation rate of the grid A gri is matched to adapt to the peak shaving variation rate coefficient b of the grid system. When the actual operation condition of the factory allows, the value of b is maximally 0.1, and is not less than 0.
[0114] In some embodiments, the values of the peak shaving variation rate coefficient b adapted to the power grid system and the power variation coefficient c adapted to the production continuity link can be adjusted to ensure that the production continuity link can adapt to the external power grid load variation as much as possible without interrupting the production continuity.
[0115] In this application, when adjusting the operation state of each production link to adapt to the external power grid peak shaving requirement, the production preparation link, the production mixed link, and the production continuity link are considered. Moreover, according to the power grid peak shaving requirement, the self-generation output of the factory is reasonably called, and the mixing effect between the released power and the power supply power is considered in the production preparation link, the production mixed link, and the production continuity link, so as to provide a more accurate control strategy for the actual power control of the target factory.

Then, the power generation power of the self-generation system of the target factory is adjusted according to the peak shaving power supply power. If the maximum power generation power of the self-generation system is less than the to-be-compensated power, the energy consumption supply deficiency power of the target factory is determined according to the energy consumption power of the target factory, the peak shaving power supply power, and the power generation power of the self-generation system, and the to-be-compensated power is the energy supply gap generated when the peak shaving power supply power changes. Finally, the operation state of each production link is adjusted step by step according to the energy consumption supply deficiency power. Since the power generation power of the self-generation system of the target factory is adjusted according to the peak shaving power supply power, and the operation state of each production link is adjusted step by step according to the energy consumption supply deficiency power, the production characteristics of different levels of production links can be dynamically adjusted and mixed controlled, so as to improve the accuracy of the operation control of the production link of the factory.

Then, the power generation power of the self-power generation system of the target factory is adjusted according to the peak regulation power supply power. If the maximum power generation power of the self-power generation system is less than the to-be-compensated power, the energy consumption supply deficiency power of the target factory is determined according to the energy consumption power of the target factory, the peak regulation power supply power and the power generation power of the self-power generation system, and the to-be-compensated power is the energy supply gap generated when the peak regulation power supply power changes.
