[0025] Please refer to Figure 1-Figure 2 , a method for selecting a site for an energy storage power station based on a combined evaluation model, including: S101: Obtain power output, grid capacity, and load demand of a plurality of power supply target areas, establish a first evaluation model, and calculate a first evaluation value based on the power output, grid capacity, and load demand based on the first evaluation model; In this embodiment, power output refers to the total power supplied by the external power grid to the target area to be powered. The powered area is comprehensively evaluated based on power output, grid capacity, and load demand to obtain a comprehensive evaluation index for the target area to be powered.

[0026] S102: Obtaining basic data of several current energy storage systems, setting calculation weights for several energy storage power stations based on the basic data, establishing a second evaluation model, and outputting several second evaluation values ​​through the second evaluation model based on the several calculation weights and the first evaluation values; Currently, there are many different types of energy storage. In addition to traditional energy storage technologies such as pumped storage, new energy storage technologies are developing rapidly. Based on the operating principles of different energy storage technologies, energy storage can be divided into three types: physical energy storage, electromagnetic energy storage, and electrochemical energy storage. Physical energy storage includes flywheel energy storage and compressed air energy storage; electromagnetic energy storage includes supercapacitors; and electrochemical energy storage includes sodium-sulfur batteries, lithium-ion batteries, lead-acid batteries, and flow batteries. With the development of technology, more new energy storage technologies will emerge. The emergence of numerous energy storage technologies has affected the selection of appropriate energy storage types in practical engineering projects. Therefore, before using energy storage selection methods, it is necessary to review the performance indicators of all types.

[0027] Specifically, a comprehensive evaluation is performed in combination with the basic data of each energy storage system, that is, the calculated data of each energy storage system is calculated with the first evaluation value of the powered target area to obtain a judgment index for each energy storage system combined with the powered target area.

[0028] S103: Setting a site selection range with the target area to be powered as the center, obtaining geographic data within the site selection range, setting pre-selected points based on the geographic data, establishing a third evaluation model, and obtaining a plurality of third evaluation values ​​for a plurality of groups of pre-selected points using the third evaluation model based on the basic data and the second evaluation values ​​of the pre-selected points; Preselected points can be screened out through geographic location and geographic data. The preselected points can be locations uploaded after manual measurement, or locations inferred through neural network recognition of remote sensing data. By combining the geographic data of the preselected points with the second evaluation value of each energy storage system, a judgment index of the energy storage system combined with the preselected points is obtained for subsequent judgment.

[0029] S104: Establishing an environmental impact model, correcting the third evaluation value using the basic data of the energy storage system and the environmental impact model, and outputting a plurality of fourth evaluation values ​​of a plurality of groups of pre-selected points after correction; In the present invention, the impact of the energy storage power station on the environment is also taken into consideration. By adding the impact on the environment, it is judged again whether the energy storage power station is suitable for construction in the pre-selected point, making the final judgment result more accurate.

[0030] S105: Setting a comprehensive evaluation value threshold. If all fourth evaluation values ​​within the current pre-selected point are greater than the comprehensive evaluation value threshold, the current pre-selected point is discarded. If there is a fourth evaluation value within the current pre-selected point that is less than or equal to the comprehensive evaluation value threshold, the current pre-selected point is retained as the site selection point. The comprehensive evaluation value threshold can be set based on experience. Historical data related to this solution can be collected after the energy storage power station is built at a certain address. These historical data are calculated using the model of this solution to obtain a standard value. The standard values ​​of several energy storage power stations are averaged to obtain an objective comprehensive evaluation value threshold. In this embodiment, the comprehensive evaluation value threshold is set to twice the average value of the fourth evaluation value.

[0031] S106: Obtaining energy storage systems corresponding to several target fourth evaluation values ​​within the site selection point as the energy storage system to be set up at the site selection point, wherein the sum of the several target fourth evaluation values ​​is not greater than the comprehensive evaluation value threshold.

[0032] In the present invention, for example, if there are five fourth evaluation values ​​that are smaller than the comprehensive evaluation value threshold at the site selection point, a number of fourth evaluation values ​​whose sum is not greater than the comprehensive evaluation value threshold are freely combined as the target fourth evaluation value, and the energy storage system corresponding to the target fourth evaluation value is an energy storage system that can be installed in the site selection point.

[0033] The method provided by the present invention mainly includes the first evaluation model, the second evaluation model, the third evaluation model and the fourth evaluation model, and sets a comprehensive evaluation value threshold. If the fourth evaluation value in the current pre-selected point is greater than the comprehensive evaluation value threshold, the current pre-selected point is discarded. If the current pre-selected point has a fourth evaluation value less than or equal to the comprehensive evaluation value threshold, the current pre-selected point is retained as the site selection point. A complete and comprehensive set of evaluation indicators is established through the above method, and the indicator weights are determined according to actual conditions. The complexity of energy storage site selection and the influence of different factors are fully considered. The constructed indicator system can also be selected according to relevant stakeholders, so that the final result is more accurate, and the site selection location is more in line with the construction requirements of the energy storage power station. In an exemplary embodiment of the present invention, establishing a first evaluation model includes: Perform dimensionless normalization on the specific data of power output, grid capacity, and load demand of several target power supply areas to obtain the normalized values ​​of each data; A first evaluation value is calculated based on the normalized numerical value, wherein the first evaluation model includes:

[0034] Where, is the first evaluation value, is the number of target areas to be powered, After normalization, The power output data value of the target area to be powered, After normalization, The grid capacity data value of the target area to be powered, After normalization, The load demand data value of the target area to be powered.

[0035] In this embodiment, the normalization method is:

[0036] Where, is the normalized value, For the input data, is the minimum value in the current data group. The maximum value in the previous data group.

[0037] Normalization improves computational accuracy and efficiency. By mapping data to a specific range (such as [0,1]), the effects of data with different dimensions or ranges can be eliminated, making calculations more accurate and efficient.

[0038] In an exemplary embodiment of the present invention, outputting a plurality of second evaluation values ​​through a second evaluation model based on the plurality of calculation weights and the first evaluation value includes:

[0039] Where, For the The second evaluation value of For the The calculation weight of the energy storage system, is the average output power of several energy storage systems, For the The output power of the energy storage system, is the average floor space occupied by several energy storage systems, For the The area occupied by the energy storage system, is the average construction cost of several energy storage systems, For the The construction cost of the energy storage system is is the average operating cost of several energy storage systems, For the The operating costs of an energy storage system.

[0040] In the present invention, the output power, floor space, construction cost, and operating cost of the energy storage system are taken into consideration. The output power can be the rated output power or the maximum output power. Based on the above basic data, a comprehensive evaluation is performed on each energy storage system, reflecting the intuitive digital presentation and comparison of each energy storage system under the current circumstances. The floor space, construction cost, and operating cost of the energy storage system are set as positive feedback to increase the second evaluation value, and the output power of the energy storage system is set as negative feedback to reduce the second evaluation value. The higher the second evaluation value, the heavier the burden on the energy storage power station.

[0041] In an exemplary embodiment of the present invention, setting a site selection range centered on the target area to be powered includes: Obtain the center point of the current power supply target area, then obtain the distance of the power unit farthest from the center point, use the distance as the radius and the center point as the center to obtain a first target circle. The target circle is the coverage range of the current power supply target area, and the radius of the second target circle is determined based on the basic data of the current power supply target area; If the number of the current powered target area is 1, the range between the first target circle and the second target circle is the site selection range; If the number of current powered target areas is not 1, determine whether there is an intersecting area among several second target circles. If there is no intersecting area, the range between the first target circle and the second target circle is the site selection range. If there is an intersecting area, the site selection range of the intersecting powered target areas is the intersecting area.

[0042] Through the above method, the site selection range can be reasonably circled, and the pre-selected point can be searched and set within the range. After obtaining the pre-selected point, combined with the second evaluation value, it is further judged whether the pre-selected point is suitable for the setting of the energy storage power station.

[0043] Secondly, determining the radius of the second target circle according to the basic data of the current powered target area includes:

[0044] Where, is the radius of the second target circle, is the radius of the first target circle, is the population density of the target area to be powered, is the national average population density, is the GDP per capita output value of the target area to be powered, is the national GDP per capita, is the load demand of the target area to be powered, The total installed capacity of power generation equipment that supplies power to the target area.

[0045] Among them, regarding the determination of the radius of the second target circle, if the range is too large, the subsequent costs involved will increase significantly. If the range is too small, it may affect the powered area. Therefore, this plan mainly considers the economic index and population index, and corrects it through electricity load to obtain a comprehensive value.

[0046] In an exemplary embodiment of the present invention, obtaining a plurality of third evaluation values ​​of a plurality of groups of pre-selected points through a third evaluation model based on the basic data of the pre-selected points and the second evaluation values ​​includes:

[0047] Where, For the The first of the pre-selected points The third evaluation value, is the minimum distance between the preselected point and the first target circle, is the maximum distance between the preselected point and the first target circle, For the The available construction area of ​​the pre-selected points, is the green coverage rate of the power supply area, It is the green plant coverage rate of the site selection range where the pre-selected point is located.

[0048] In the present invention, a comprehensive judgment is made through the geographical data of the pre-selected points, that is, the pre-selected points and each energy storage system are combined to obtain a comprehensive judgment data, and subsequent judgments are made based on this data, which can better reflect the current situation of the combination of the pre-selected points and the energy storage system.

[0049] In an exemplary embodiment of the present invention, establishing an environmental impact model and revising the third evaluation value using basic data of the energy storage system and the environmental impact model includes: The environmental impact model includes:

[0050] Where, is the fourth evaluation value, is the green area within the pre-selected point, The economic value of green plants within the pre-selected points.

[0051] Among them, environmental factors are taken into consideration. Some energy storage systems in energy storage power stations may have a greater impact on the environment, such as chemical energy storage systems or pumped storage systems, which require significant changes to the local terrain. Therefore, environmental factors are comprehensively considered to make the final results more accurate.

If all fourth evaluation values ​​within the current preselected point are greater than the comprehensive evaluation value threshold, the current preselected point is discarded. If a fourth evaluation value less than or equal to the comprehensive evaluation value threshold exists within the current preselected point, the current preselected point is retained as the site selection point. The energy storage systems corresponding to several target fourth evaluation values ​​within the site selection point are obtained as the energy storage systems to be set up at the site selection point, and the sum of the several target fourth evaluation values ​​is not greater than the comprehensive evaluation value threshold.
