[0002] The voltage level sequence is an important specification for the design, construction, equipment and operation and maintenance of all links of power system transmission, distribution and use. A voltage level sequence with reasonable level difference and appropriate number can effectively reduce the investment in power system construction and the operation and maintenance costs. In the process of my country's power grid development and voltage level series simplification, 10 kV was promoted as the medium voltage distribution voltage and 35 kV as the high voltage distribution voltage. There are a large number of 10 kV and 35 kV stock power facilities in the current power grid.

[0038] Embodiment 1

[0039] Figure 1 A flowchart for determining a power grid construction plan provided in an embodiment of the present disclosure is applicable to situations where a reasonable selection and simplified configuration of a voltage level sequence is provided. The method can be executed by a device for determining a power grid construction plan, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC, a server, etc.

[0040] like Figure 1As shown, a method for determining a power grid construction plan provided by an embodiment of the present disclosure may specifically include the following steps:

[0041] S110. Obtain construction requirement information of the substation to be constructed.

[0042] The construction demand information includes: load power supply demand information and substation line circuit number demand information.

[0043] In this embodiment, the construction demand information may be the demand information of the target area to be constructed. Under the combined boundaries of load density, load structure, and power supply mode within the power supply range of the blank area, in order to ensure the power supply requirements within the power supply area, the power balance and the number of facility power line loop constraints must be met.

[0044] Specifically, obtain construction demand information in the area to be constructed.

[0045] S120. Obtain a model for determining a power grid construction plan.

[0046] Among them, the grid construction plan determination model is constructed based on the attribute information of substations at each voltage level.

[0047] Optionally, the construction process of the power grid construction plan determination model may be:

[0048] a1) Determine the construction cost impact coefficient corresponding to different attribute information of substations of different voltage levels;

[0049] b1) The sum of the product of each attribute information of each voltage level substation and the corresponding construction cost impact coefficient is used as the construction impact relationship of the power grid construction plan determination model;

[0050] c1) extracting power supply capacity information included in the attribute information of each voltage level substation, and determining the power supply impact coefficient of each voltage level substation;

[0051] d1) Determine the product of the power supply capacity information of each voltage level substation and the power supply impact coefficient, and use the sum of each product as the power supply impact relationship of the power grid construction plan determination model.

[0052] Among them, the attribute information includes: station construction cost, line cost, line length, operation cost and social resource occupation cost. The power supply capacity information includes: power supply amount and number of line loops; the power supply impact coefficient includes: power supply demand impact coefficient and line loop impact coefficient.

[0053] In this embodiment, the construction cost impact coefficient may be a corresponding impact relationship index between the construction cost and the attribute information, and the power supply impact coefficient may be an impact coefficient between the power supply capacity information and the power supply capacity of each voltage level substation.

[0054] Specifically, the construction cost impact coefficient corresponding to the different attribute information of the substations of each voltage level is determined, and the sum of the products of the attribute information of the substations of each voltage level and the corresponding construction cost impact coefficient is used as the construction impact relationship of the power grid construction plan determination model, the power supply capacity information included in the attribute information of the substations of each voltage level is extracted, and the power supply impact coefficient of the substations of each voltage level is determined, the product of the power supply capacity information of the substations of each voltage level and the power supply impact coefficient is determined, and the sum of each product is used as the power supply impact relationship of the power grid construction plan determination model.

[0055] Optionally, the method of determining the product of the power supply capacity information of each voltage level substation and the power supply impact coefficient, and taking the sum of the products as the power supply impact relationship of the power grid construction plan determination model may be:

[0056] d11) Determine the product of the power supply of each voltage level substation and the power supply demand impact coefficient.

[0057] d12) Determine the product of the number of line loops and the line loop influence coefficient of each voltage level substation.

[0058] d13) The sum of the products is used as the power supply impact relationship of the power grid construction plan to determine the model.

[0059] Exemplarily, the construction process of the construction impact relationship in the grid construction plan determination model is as follows: It should be known that the power facility cost parameters include: unit initial investment, annual equivalent operating cost and equivalent cost of social resource occupation for substations and lines of different voltage levels such as 110 kV and 35 kV. Among them, the social resource occupation cost refers to the equivalent cost of land resources occupied by substation site selection and line selection and other social impacts generated by them. It can be calculated based on the scale of facility land combined with unit land acquisition costs. For urban scenarios where land resources are very tight, this fee can be appropriately increased. Regional power demand parameters include: regional planning scope and land area, load density and load structure. Among them, the load structure refers to the power composition of users in the region. For example: the power load level of general residential users, the power load level of large industrial users, and the power load level of non-industrial large users. In order to facilitate research, users can be classified and sorted according to the power level and interval range. The boundaries of the power supply mode include: the connection types to be adopted in the regional planning of 110 kV, 35 kV and other different voltage levels of power grids, such as double-sided power supply chain connection type, double-sided power supply radial connection type, double-sided power supply ring network connection type, etc., the correspondence between the power supply voltage level and the power consumption level, that is, the voltage level selection rules adopted by users in a specific capacity range for power supply, the number of user power supply circuits, and the maximum allowable number of power supply line circuits for unit power facilities of different voltage levels such as 110 kV and 35 kV.

[0060] A regional power supply model with associated substations and lines is established based on the requirements of the grid connection type. Assuming that the load is evenly distributed in the region, the number of substations and the length of the corresponding voltage level lines are correlated within a specific area. The more substations there are at each level, the smaller the power supply range of a single substation, and the shorter the length of the new power supply line required to meet the power supply needs of users within its power supply range. Vice versa. A model describing the relationship between the length of the power supply line and the number of substations is established based on the grid connection type.

[0061] The first type is a double-sided power chain wiring model. Figure 2 The schematic diagram of the double-side power chain wiring and modeling provided by the embodiment of the present disclosure is as follows: Figure 2 As shown in the figure, taking the 110 kV power grid as an example, chain connection refers to a "hand-in-hand" connection method formed by multiple 110 kV substations using the upper 220 kV substations on both sides as power supply points, and a new 110 kV line is built from one side of the power supply to connect the 110 kV substations in sequence, and finally reaches the power supply on the other side. The formation of N such chain connections is called N chain connections. The average line length L of a newly built single 110 kV substation is described by the power supply radius and load density of the power facilities. ρ110 :

[0062]

[0063] Where: S1, S2 is the power supply capacity of a single 220 / 110 kV substation; ρ is the average load density; k1 is the wiring length coefficient. According to the double-side power supply, N-link wiring, considering the line tortuosity coefficient Calculated as:

[0064] The second type is the double-sided power supply radial wiring model. Figure 3 The schematic diagram of the double-sided power supply radiation wiring and modeling provided in the embodiment of the present disclosure is as follows: Figure 3 As shown in the figure, taking the 35 kV power grid as an example, radial wiring refers to a wiring method in which a single 35 kV substation uses the upper 220 kV substations on both sides as power supply points, and builds a new 35 kV line from each power supply point to the station. The substation using the modified wiring type has a total of 2 power supply lines of corresponding voltage levels. The average line length L of a newly built single 35 kV substation is described by the power supply radius and load density of the power facilities. ρ35 :

[0065]

[0066] Among them: S1, S3 are the power supply capacity of a single 220 / 35 kV substation; ρ is the average load density; k2 is the wiring length coefficient. According to the double-side power supply, radial wiring, and considering the line tortuosity coefficient Calculated as:

[0067] The third type is the double-sided power ring network wiring model. Figure 4 The ring network wiring and modeling diagram provided in the embodiment of the present disclosure is as follows: Figure 4 As shown in the figure, the ring network connection type has some similarities with the double-side power chain connection model, but it allows new lines to be built from the same power source point to connect the lower-level substations in series, and the lines finally return to the power source point. To illustrate a more complex situation, taking the 10 kV power grid as an example, the more substations (including 110 kV and 35 kV substations) are distributed within a unit area, the shorter the line length required to build a 10 kV ring network connection in theory. The following relationship is used to evaluate the outgoing line length L ρ10 :

[0068]

[0069] S is the total area of ​​the power supply area; n s_110 ,n s_35 is the number of 110 kV and 35 kV power facilities in the power supply area; ρ is the average load density; k3 is the networking coefficient, and the calculation method is the same as the chain connection length coefficient.

[0070] Construct the objective function in the power grid construction plan determination model. The objective function takes economic efficiency as the optimization goal, that is, the sum of the equivalent cost of substation and line construction, operation cost and social resource occupation in the power supply plan is optimal.

[0071] The construction cost includes two parts: substation and line.

[0072] Investment in the construction of the power substation part of the power grid project f1:

[0073]

[0074] Investment in construction of power grid line part f2:

[0075]

[0076] in:

[0077] n s_220 ,n s_110 ,n s_35 ,n s_10 is the number of 220 / 110 / 35 kV substations and 10 kV grid switch stations to be newly built, i is the facility number;

[0078] C s220 ,C s110 ,C s35 ,C s10The proposed new single 220 / 110 / 35 kV substation and 10 kV switch station investment, i is the facility number; C l220 ,C l110 ,C l35 ,C l10 The cost per kilometer of the proposed new 220 / 110 / 35 / 10 kV line; L ρ110 ,L ρ35 ,L ρ10 The average length of the 110 / 35 / 10 kV power line is used to build a single 110 / 35 / 10 power facility. The total cost over the entire life cycle is calculated based on the operating cost. The annual operating cost is estimated by averaging a certain proportion of the construction cost incurred in each year of the life cycle, as shown in the following formula:

[0079]

[0080]

[0081] In the formula: t1, t2 are the annual operating cost ratios of substation equipment and line equipment respectively; i% ​​is the discount rate; N is the operating life of the equipment. The social resource equivalent cost further considers the social resource occupation attribute correction item, as shown in the following formula:

[0082]

[0083]

[0084] Among them: k1 is the cost item of land resources occupied by the introduced site, k2 and k3 are the cost items of channel resources occupied by the introduced lines. At the site level, the power supply capacity of a single 110 kV substation is stronger than that of a 35 kV substation, so the site resource demand is small; but the channel resource demand occupied by the corresponding 110 kV line is higher than that of the 35 kV line. Therefore, different comparison results may be obtained under different parameter combinations.

[0085] Exemplarily, the construction process of the power supply impact relationship in the power grid construction plan determination model is as follows: construct the power supply voltage level sequence to select the optimization model constraint conditions. Under the combined boundary of load density, load structure, and power supply mode within the power supply range of the blank area, in order to ensure the power supply requirements within the power supply area, the power balance and the number of facility power line loop constraints must be met.

[0093] S 220 ,S 110 ,S 35 It is the power supply capacity that a single 220 / 110 / 35 kV substation can meet under the N-1 mode, that is, the maximum allowable load rate of a single substation that can meet the N-1 verification, such as 50% for two main substations and 67% for three main substations;

[0094] S L∑ ,S L_10 ,S L_0.4 It is total load / 10 kV and below / 0.4 kV load demand;

[0098] The number of power line loops of the facility is constrained. The maximum number of power lines that the proposed new substation in the area can provide should not be less than the total number of power lines required by users under the established power supply mode. The scale of the facility that can provide a certain voltage level interval outgoing line must match the number of required circuits for the interval of that voltage level.

[0099] The 110 kV interval meets the supply and demand constraints:
