Description

Technical Field

[0001] This invention relates to a method for allocating daily load in a regional power grid. Background Technology

[0002] To ensure a reliable power supply for residents, while minimizing the impact on industrial loads and achieving fair, just, and transparent power dispatching, there is an urgent need to provide a daily load allocation method that meets these requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a method for allocating the daily load of a regional power grid. This method can solve the problem that, under normal circumstances, the daily load of a regional power grid is not allocated to the power grids at the district and county levels. This results in imbalances between power grid supply and demand, especially at night when photovoltaic power generation is essentially zero, during peak summer and winter periods, and at night when photovoltaic power generation is essentially zero. Industrial loads can easily affect residential loads, thus impacting the normal power supply to residents.

[0004] The technical solution adopted by this invention to solve its technical problem is: a method for allocating daily load of a regional power grid, comprising the following steps:

[0005] Step (1): Divide all users in the regional power grid into residential electricity users and industrial electricity users according to their electricity consumption nature. Define the total daily load of residential electricity users as A and the total daily load of industrial electricity users as B.

[0006] Step (2): By comparing the month-on-month and year-on-year comparisons, the historical highest value of A in the regional power grid is obtained and defined as the benchmark value C;

[0007] Step (3): Obtain the growth rate of regional power grid A through historical data, take the highest value, add the set threshold, and obtain the estimated growth rate of regional power grid A, which is defined as D;

[0008] Step (4): Multiply the growth rate D by the benchmark value C to obtain the maximum reserved load value of A, which is defined as E;

[0009] Step (5): Define the total amount of B in the regional power grid as 1;

[0010] Step (6): Based on the same period of the previous year, obtain the historical highest value of the total daily load of industrial electricity consumption in each district and county-level regional power grid under the regional power grid, and compare it to obtain the ratio between the total daily load of industrial electricity consumption in each district and county-level regional power grid. Then, according to step (5), calculate the ratio according to the ratio to obtain the proportion of the total daily load of industrial electricity consumption in each district and county-level regional power grid relative to B in the regional power grid, which is defined as F.

[0011] Step (7): Define the total daily load allocated by the upper-level power grid to the regional power grid as G. Then, the remaining daily load of industrial electricity that can be allocated to each district and county-level regional power grid is: B = GE;

[0012] Step (8): Define the total daily load of industrial electricity that can be allocated to each district and county-level regional power grid as H. Then H = B multiplied by F. Once the total daily load of industrial electricity in each district and county-level regional power grid is obtained, the allocation is completed.

[0013] Furthermore, the growth rate in step (3) is calculated as follows: compared with the annual growth rate of A in the regional power grid over the past five years, the highest value is taken, and a set threshold is added to obtain the estimated growth rate of A in the current year, which is defined as D.

[0014] Furthermore, the growth rate calculation method in step (3) can also be: using the month-on-month comparison, the monthly growth rate of regional power grid A is obtained and compared with the annual growth rate. The maximum value is defined as D. The growth rate calculation method can be selected from the two methods as needed.

[0015] To further improve the reliability of the growth rate, in step (3), when calculating the growth rate, two values ​​are first obtained through two calculation methods, and then the larger value is selected by comparison and defined as D.

[0016] The beneficial effects of this invention are as follows: In this invention, the maximum reserved load value of the total daily load of residential electricity consumption is directly obtained according to the growth rate, and the total daily load of residential electricity consumption is directly reserved. Then, the remaining portion of the total daily load allocated by the tertiary power grid to the regional power grid is used to allocate industrial electricity. This allocation method directly ensures the normal power supply to residential electricity consumption and avoids the impact of industrial electricity consumption on residential electricity consumption during peak electricity consumption periods.

[0017] Based on the proportion of the total daily industrial electricity load of each district and county-level regional power grid to the total daily industrial electricity load within the regional power grid, the total daily industrial electricity load of each district and county-level regional power grid is obtained. This enables the allocation of the total daily industrial electricity load of each district and county-level regional power grid, achieving the most reasonable allocation possible, making the power grid supply and demand more balanced, and improving the fairness, impartiality, and transparency of power dispatch.

[0018] The present invention will be described in more detail below with reference to the embodiments. Detailed Implementation

[0019] An example of a method for allocating daily load in a regional power grid includes the following steps:

[0020] Step (1): Divide all users in the regional power grid into residential electricity users and industrial electricity users according to their electricity consumption nature. Define the total daily load of residential electricity users as A and the total daily load of industrial electricity users as B.

[0021] Step (2): By comparing the month-on-month and year-on-year comparisons, the historical highest value of A in the regional power grid is obtained and defined as the benchmark value C;

[0022] Step (3): Obtain the growth rate of regional power grid A through historical data, take the highest value, add the set threshold, and obtain the estimated growth rate of regional power grid A, which is defined as D;

[0023] Step (4): Multiply the growth rate D by the benchmark value C to obtain the maximum reserved load value of A, which is defined as E;

[0024] Step (5): Define the total amount of B in the regional power grid as 1;

[0025] Step (6): Based on the same period of the previous year, obtain the historical highest value of the total daily load of industrial electricity consumption in each district and county-level regional power grid under the regional power grid, and compare it to obtain the ratio between the total daily load of industrial electricity consumption in each district and county-level regional power grid. Then, according to step (5), calculate the ratio to obtain the proportion (which can be a percentage) of the total daily load of industrial electricity consumption in each district and county-level regional power grid relative to B in the regional power grid, which is defined as F.

[0026] Step (7): Define the total daily load allocated by the upper-level power grid to the regional power grid as G. Then, the remaining daily load of industrial electricity that can be allocated to each district and county-level regional power grid is: B = GE;

[0027] Step (8): Define the total daily load of industrial electricity that can be allocated to each district and county-level regional power grid as H. Then H = B multiplied by F. Once the total daily load of industrial electricity in each district and county-level regional power grid is obtained, the allocation is completed.

[0028] The total amount of B in the regional power grid in step (5) is not limited to being defined as 1. For example, it can be defined as 100, as long as the ratio between the total daily load of industrial electricity consumption in each district and county-level regional power grid in step (6) can be achieved. The main purpose of the ratio is to obtain the percentage of the total daily load of industrial electricity consumption in each district and county-level regional power grid to the total amount of B in the regional power grid. This is to facilitate the allocation of the daily load of industrial electricity consumption in each district and county-level regional power grid in step (8) based on the regional power grid B.

[0029] The growth rate in step (3) is calculated as follows: compared with the annual growth rate of A in the regional power grid over the past five years, the highest value is taken, and a set threshold is added to obtain the estimated growth rate of A in the regional power grid for the current year, which is defined as D.

[0030] In Example 2, the growth rate calculation method in step (3) can also be: using month-on-month comparison, the monthly growth rate of regional power grid A is obtained and compared with the annual growth rate. The maximum value is defined as D. The growth rate calculation method can be selected from the two methods as needed. The rest is the same as in Example 1.

[0031] In Example 3, when calculating the growth rate in step (3), two values ​​are first obtained through two calculation methods, and then compared. The larger value is taken and defined as D. The rest is the same as in Example 2.
