[0023] To solve or improve the problems raised by the background, the present application provides a load index allocation method based on industrial load proportionality as shown in Figure 1 A load index allocation method based on industrial load proportionality includes: S1, obtaining the total industrial load value of the target area in the power limiting period, predicting the maximum power consumption load according to the climate parameters of the next day, and determining the power supply parameters of the next day according to the power supply within the target area; S2, obtaining the power limiting load parameters based on the maximum power consumption load and the power supply parameters; S3, allocating the load index according to the power limiting load parameters and the total industrial load value.

[0024] The principle of the load index allocation method based on industrial load proportionality includes:

[0025] 1. Statistics of the industrial load base of each city in the province during the power limiting period: GYFH1, GYFH2,..., GYFHN.

[0026] 2. Add the industrial loads of each city to obtain the total industrial load value of the province during the power limiting period: GYFHZ = GYFH1 + GYFH2 +... + GYFHN.

[0027] 3. When preparing the power consumption index of the next day, first obtain the temperature and weather of the next day according to the weather forecast to predict the maximum power consumption load FHG of the next day.

[0028] 4. Add the industrial loads of each city to obtain the total industrial load value of the province during the power limiting period: GYFHZ = GYFH1 + GYFH2 +... + GYFHN.

[0029] 5. Statistics of the output capacity of wind power, photovoltaic, hydropower, thermal power, nuclear power and biomass power plants in the province on the next day to determine the maximum supply capacity GYG of the province on the next day.

[0030] 6. Calculate the total power limiting load value XDG of the next day: XDG = predicted maximum power consumption load FHG of the next day - maximum supply capacity GYG of the province on the next day.

[0031] 7. If the total power limiting load value XDG of the next day is less than or equal to the total industrial load value GYFHZ of the province, i.e. only industrial load is required to meet the requirements, then start allocating power limiting index according to industrial proportion. If the total power limiting load value XDG of the next day is greater than the total industrial load value GYFHZ of the province, report to the government energy supervision department that residential power consumption needs to be limited, and the government coordinates and supervises each power source to increase output to meet the total power limiting load value XDG of the next day.

[0032] 8. Calculate the proportion of the next day's power rationing to industrial load BLX=total value of next day's power rationing load XDG / total value of industrial load in the province GYFHZ.

[0033] 9. Then the next day's power rationing value of each city is: DFH1=GYFH1*BLX, XDGYFH2=GYFH2*BLX,..., XDGYFHN=GYFHN*BLX.

[0034] 10. Thus, the target of 100% power rationing and no residential electricity is ensured.

[0035] Obtain the total value of industrial load of a target area in a power rationing period, predict the maximum electricity load according to the climate parameters of the next day, determine the power supply parameters of the next day according to the power sources in the target area, obtain the power rationing load parameters based on the maximum electricity load and the power supply parameters, and allocate the load index according to the power rationing load parameters and the total value of industrial load. The load index is shared according to the industrial load proportion of each city. The city with high industrial load shares more power rationing index, and the city with less industrial load shares less power rationing index. The fairness of industrial load power rationing is ensured, and the target of ensuring residential electricity not being limited in the period of limited power supply capacity and electricity shortage is also ensured.

[0036] The obtaining of the power rationing load parameters based on the maximum electricity load and the power supply parameters comprises: calculating the difference between the maximum electricity load and the power supply parameters as the power rationing load parameters.

[0037] The allocation of the load index according to the power rationing load parameters and the total value of industrial load comprises: if the power rationing load parameters are not greater than the total value of industrial load, the power rationing index is allocated according to the industrial proportion; if the power rationing load parameters are greater than the total value of industrial load, the power supply is reported to the power management department that the expected power supply cannot meet the residential electricity, and the power source is required to increase the power supply by the power management department.

[0038] The target area comprises each area belonging to the provincial area. Correspondingly, the obtaining of the total value of industrial load of the target area in the power rationing period comprises: obtaining the industrial load base of each area and adding them to obtain the total value of industrial load.

[0039] The allocation of the load index according to the power rationing load parameters and the total value of industrial load further comprises: calculating the quotient of the power rationing load parameters and the total value of industrial load; and obtaining the power rationing value of the corresponding area according to the product of the quotient and the industrial load base of each area.

[0040] The application provides a load index distribution device based on industrial load proportionality, comprising: a first unit 1 for obtaining the total industrial load value of a target area during a power limiting period, predicting the maximum power consumption load according to the climate parameters of the next day, and determining the power supply parameters of the next day according to the power supply in the target area; a second unit 2 for obtaining the power limiting load parameters based on the maximum power consumption load and the power supply parameters; and a third unit 3 for distributing the load index according to the power limiting load parameters and the total industrial load value.

[0041] The operation principle of the load index distribution device based on industrial load proportionality comprises:

[0042] 1. The industrial load base numbers GYFH1, GYFH2,..., GYFHN of each city in the province during the power limiting period are counted.

[0043] 2. The industrial loads of each city are added to obtain the total industrial load value GYFHZ of the province during the power limiting period.

[0044] 3. When the power consumption index of the next day is prepared in advance, the maximum power consumption load FHG of the next day is predicted according to the weather forecast to obtain the temperature and weather of the next day.

[0045] 4. The industrial loads of each city are added to obtain the total industrial load value GYFHZ of the province during the power limiting period.

[0046] 5. The output capacity of the next day of the wind power, photovoltaic, hydropower, thermal power, nuclear power and biomass power plants in the province is counted to determine the maximum supply capacity GYG of the province.

[0047] 6. The total limiting load value XDG of the next day is calculated as XDG = predicted maximum power consumption load FHG - maximum supply capacity GYG of the province.

[0048] 7. If the total limiting load value XDG of the next day is less than or equal to the total industrial load value GYFHZ of the province, that is, only the industrial load can meet the requirements, the limiting load index is distributed according to the industrial proportion. If the total limiting load value XDG of the next day is greater than the total industrial load value GYFHZ of the province, the government energy supervision department is reported to limit the residential power consumption, and the government coordinates and supervises each power source to increase the output to meet the total limiting load value XDG of the next day GYFHZ of the province, and ensures that the power consumption is not limited and the residential power consumption is not limited.

[0049] 8. The proportion BLX of the limiting load to the industrial load of the next day is calculated as BLX = total limiting load value XDG of the next day / total industrial load value GYFHZ of the province.

[0050] 9. The power rationing values ​​for each city on the next day are: DFH1=GYFH1*BLX, XDGYFH2=GYFH2*BLX, ..., XDGYFHN=GYFHN*BLX.

[0051] 10. This will ensure the achievement of the goal of 100% unrestricted power supply and residential electricity consumption.

[0052] The process involves obtaining the total industrial load of the target area during the power rationing period, predicting the peak electricity load based on the climate parameters of the next day, and determining the power supply parameters for the next day based on the power sources within the target area. Based on the peak electricity load and the power supply parameters, the power rationing load parameters are obtained. According to the power rationing load parameters and the total industrial load, load quotas are allocated, distributing the power rationing quotas according to the industrial load ratio of each city. Cities with high industrial loads receive a larger share of the power rationing quotas, while cities with low industrial loads receive a smaller share. This ensures fairness in industrial load rationing while also guaranteeing that residential electricity use remains unrestricted during periods of limited power supply and power shortages.

[0053] The step of obtaining the power-limited load parameter based on the highest power load and the power supply parameters includes: calculating the difference between the highest power load and the power supply parameters as the power-limited load parameter.

[0054] The method of allocating load indicators based on the power rationing load parameters and the total industrial load includes: if the power rationing load parameters are not greater than the total industrial load, then the power rationing indicators are allocated according to the industrial ratio; if the power rationing load parameters are greater than the total industrial load, then the power management department is not expected to meet the residential electricity demand, and the power management department requests the power source to increase its power supply.

[0055] The target area includes all regions belonging to the provincial region; correspondingly, obtaining the total industrial load value of the target area during the power rationing period includes: obtaining the industrial load base of each region and adding them together to obtain the total industrial load value.

[0056] The method of allocating load indicators based on the power rationing load parameters and the total industrial load value further includes: calculating the quotient of the power rationing load parameters and the total industrial load value; and obtaining the power rationing value for the corresponding region based on the product of the quotient and the industrial load base value for each region.
