[0048] Please refer to Figures 1-2 A site selection method for energy storage power stations based on a combined evaluation model includes:

[0049] S101: Obtain the power output, grid capacity, and load demand of several target areas to be powered, establish a first evaluation model, and calculate the first evaluation value based on the power output, grid capacity, and load demand using the first evaluation model;

[0050] In this embodiment, power output refers to the total power supplied by the external power grid to the target area. The target area is comprehensively evaluated by considering three aspects: power output, grid capacity, and load demand, to obtain a comprehensive evaluation index for the target area.

[0051] S102: Obtain basic data of several types of energy storage systems, set calculation weights for several energy storage power stations based on the basic data, establish a second evaluation model, and output several second evaluation values ​​based on several calculation weights and the first evaluation value through the second evaluation model;

[0052] Currently, energy storage technologies are diverse. Besides traditional technologies like pumped hydro storage, new energy storage technologies are developing rapidly. Based on their working principles, energy storage can be categorized into three types: physical energy storage, electromagnetic energy storage, and electrochemical energy storage. Physical energy storage includes forms such as flywheel energy storage and compressed air energy storage; electromagnetic energy storage includes supercapacitors; and electrochemical energy storage includes forms such as sodium-sulfur batteries, lithium-ion batteries, lead-acid batteries, and flow batteries. Furthermore, with technological advancements, even more new energy storage technologies will emerge. The proliferation of energy storage technologies has impacted the selection of appropriate energy storage types in practical engineering applications. Therefore, before using energy storage selection methods, it is essential to analyze the performance indicators of all types.

[0053] Specifically, a comprehensive evaluation is conducted by combining the basic data of each energy storage system. This involves calculating the data of each energy storage system with the first evaluation value of the target area to obtain a judgment index for the combination of each energy storage system and the target area.

[0054] S103: Set the site selection range with the target area to be powered as the center, obtain the geographical data within the site selection range, set the pre-selected points based on the geographical data, establish a third evaluation model, and obtain several third evaluation values ​​of several sets of pre-selected points through the third evaluation model based on the basic data and second evaluation values ​​of the pre-selected points.

[0055] Pre-selected points can be selected by using geographical location and geographic data. These pre-selected points can be locations that have been manually measured and uploaded, or locations that have been identified and calculated by neural networks using remote sensing data. By combining the geographic data of the pre-selected points with the second evaluation value of each energy storage system, a judgment index for the energy storage system combined with the pre-selected points is obtained, which is used for subsequent judgment.

[0056] S104: Establish an environmental impact model, correct the third evaluation value based on the basic data of the energy storage system and the environmental impact model, and output the corrected fourth evaluation value for several pre-selected points.

[0057] In this invention, the environmental impact of the energy storage power station is also considered. By incorporating the environmental impact, the suitability of the energy storage power station for construction at the pre-selected site is determined again, making the final judgment more accurate.

[0058] S105: Set a comprehensive evaluation value threshold. If all fourth evaluation values ​​in the current pre-selected point are greater than the comprehensive evaluation value threshold, discard the current pre-selected point. If there is a fourth evaluation value in the current pre-selected point that is less than or equal to the comprehensive evaluation value threshold, retain the current pre-selected point as the site selection point.

[0059] The comprehensive evaluation threshold can be set based on experience. Historical data related to this scheme can be collected after the construction of this type of energy storage power station at a certain address. After these historical data are calculated by the model of this scheme, a standard value is obtained. The average value of the standard values ​​of several energy storage power stations can be used to obtain an objective comprehensive evaluation threshold. In this embodiment, the comprehensive evaluation threshold is set to twice the average value of the fourth evaluation value.

[0060] S106: Obtain the energy storage system 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 several target fourth evaluation values ​​is not greater than the comprehensive evaluation value threshold.

[0061] In this invention, for example, if there are 5 fourth evaluation values ​​at the site selection point that are less than the comprehensive evaluation value threshold, then a number of fourth evaluation values ​​whose sum is not greater than the comprehensive evaluation value threshold can be freely combined as the target fourth evaluation value. The energy storage system corresponding to the target fourth evaluation value is an energy storage system that can be installed at the site selection point.

[0062] The method provided by this invention mainly includes a first evaluation model, a second evaluation model, a third evaluation model, and a fourth evaluation model. A comprehensive evaluation value threshold is set. 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 a site selection point. This method establishes a complete and comprehensive set of evaluation indicators, and determines the indicator weights according to actual conditions. It fully considers the complexity of energy storage site selection and the influence between different factors. The constructed indicator system can also be selected based on relevant stakeholders, making the final results more accurate and the selected sites more in line with the construction requirements of energy storage power stations.

[0063] In one exemplary embodiment of the present invention, establishing a first evaluation model includes:

[0064] Dimensionless normalization is performed on the specific data of power output, grid capacity and load demand of several target power supply areas to obtain normalized values ​​for each data type.

[0065] The first evaluation value is calculated based on the normalized numerical values. The first evaluation model includes:

[0066]

[0067] In the formula, As the first evaluation value, The number of target areas to be powered. For the normalized first Power output data values ​​for each target area being powered. For the normalized first Data value of the power grid capacity of the target power supply area. For the normalized first Load demand data values ​​for each power supply target area.

[0068] In this embodiment, the normalization method adopted is:

[0069]

[0070] In the formula, The normalized value. For the input data, The minimum value in the current data group. This represents the maximum value among the groups in the previous data.

[0071] Normalization improves computational accuracy and efficiency. By mapping data to a specific range (such as [0,1]), the influence of data with different dimensions or ranges can be eliminated, making calculations more accurate and efficient.

[0072] In one exemplary embodiment of the present invention, the step of outputting several second evaluation values ​​through a second evaluation model based on several calculated weights and a first evaluation value includes:

[0073]

[0074] In the formula, For the first The second evaluation value, For the first The calculation weights of various energy storage systems The average output power of several energy storage systems For the first The output power of this type of energy storage system The average footprint of several types of energy storage systems. For the first The footprint of this type of energy storage system The average construction cost of several types of energy storage systems. For the first The construction cost of this type of energy storage system The average operating cost of several types of energy storage systems For the first The operating costs of various energy storage systems.

[0075] In this invention, the output power, floor space, construction cost, and operating cost of the energy storage system are considered. The output power can be the rated output power or the maximum output power. Based on the above basic data, each energy storage system is comprehensively evaluated, reflecting a direct digital presentation and comparison of each energy storage system under the current conditions. The floor space, construction cost, and operating cost of the energy storage system are set as positive feedback to increase the second evaluation value, while the output power of the energy storage system is set as negative feedback to decrease the second evaluation value. The higher the second evaluation value, the heavier the burden on the energy storage power station.

[0076] In one exemplary embodiment of the present invention, setting the location range centered on the target area to be powered includes:

[0077] If the center point of the current power supply target area is obtained, the distance of the power-consuming unit farthest from the center point is obtained. Using the distance as the radius and the center point as the center, a first target circle is obtained. The target circle is the coverage area of ​​the current power supply target area. The radius of the second target circle is determined based on the basic data of the current power supply target area.

[0078] If the number of current power supply target areas is 1, then the range between the first target circle and the second target circle is the location range;

[0079] If the number of current power supply target areas is not 1, then it is determined whether there is an intersection area among the several second target circles. If there is no intersection area, then the range between the first target circle and the second target circle is the location range. If there is an intersection area, then the location range of the intersecting power supply target areas is the intersection area.

[0080] Using the above method, the site selection area can be reasonably delineated, and pre-selected points can be found and set within this area. After obtaining the pre-selected points, the second evaluation value is used to further determine whether the pre-selected points are suitable for setting up energy storage power stations.

[0081] Secondly, determining the radius of the second target circle based on the current basic data of the target area being powered includes:

[0082]

[0083] In the formula, Let the radius of the second target circle be . Let be the radius of the first target circle. The population density of the target area for power supply. The national average population density The per capita GDP of the target area for electricity supply. For the national per capita GDP, For the load demand of the target area to be powered, The total installed capacity of power generation equipment supplying power to the target area.

[0084] Regarding the determination of the radius of the second target circle, if the range is too large, the subsequent costs will increase significantly; if the range is too small, it may affect the area being powered. Therefore, this scheme mainly considers economic and population indices and corrects them through electricity load to obtain a comprehensive value.

[0085] In one exemplary embodiment of the present invention, obtaining several third evaluation values ​​for several sets of pre-selected points through a third evaluation model based on the basic data and second evaluation values ​​of the pre-selected points includes:

[0086]

[0087] In the formula, For the first The first of the pre-selected points The third evaluation value, The minimum distance between the pre-selected point and the first target circle. The maximum distance from the pre-selected point to the first target circle. For the first The usable construction area of ​​each pre-selected site The green coverage rate of the area being supplied with electricity. The green coverage rate of the site selection area where the pre-selected site is located.

[0088] In this invention, a comprehensive judgment is made by using the geographical data of the pre-selected points. This involves combining the pre-selected points with various energy storage systems to obtain comprehensive judgment data. Subsequent judgments are made based on this data, which better reflects the current integration status of the pre-selected points with the energy storage systems.

[0089] In one exemplary embodiment of the present invention, the step of establishing an environmental impact model and correcting the third evaluation value using the basic data of the energy storage system and the environmental impact model includes:

[0090] The environmental impact model includes:

[0091]

[0092] In the formula, It is the fourth evaluation value. The green area within the pre-selected site. To assess the economic value of the greenery within the pre-selected sites.

[0093] Environmental factors were taken into account. Some energy storage systems in energy storage power stations may have a significant impact on the environment. For example, chemical energy storage systems or pumped hydro storage systems require significant changes to the local terrain. Therefore, environmental factors were taken into account to make the final results more accurate.

[0094] The energy storage power station site selection system based on the combined evaluation model includes:

[0097] The judgment module is configured to set 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 energy storage system corresponding to several target fourth evaluation values ​​within the site selection point is obtained as the energy storage system to be set at the site selection point, and the sum of several target fourth evaluation values ​​is not greater than the comprehensive evaluation value threshold.
