Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0064] The embodiment of the present invention provides a method for evaluating the development potential of solar energy resources. Figure 1 As shown, the solar energy resource development potential assessment method includes:
[0065] S101. Calculate the solar energy resource data, permitted area data, and surrounding environment data of each candidate area using a preset comprehensive analysis model to obtain development data of each candidate area, and select areas to be developed from each candidate area based on the development data.
[0066] Optionally, in an optional embodiment of the present invention, the solar energy resource data may include: horizontal plane irradiation, annual sunshine hours, and annual effective sunshine days, etc. The permitted area data may include: terrain data and prohibited construction area data, etc. The surrounding environment data may include: data on existing power stations, power grid data, and traffic data, etc. The present invention analyzes and screens the areas to be developed from multiple perspectives, including solar energy resource data, permitted area data, and surrounding environment data. Compared to the prior art method of dividing the overall development area, the present invention improves the accuracy of the data used to calculate the solar energy resource development potential score while ensuring calculation efficiency.
[0067] S102. Based on the spatial coordinates of the areas to be developed, a preset GIS spatial analysis algorithm is used to perform a multi-layer overlay analysis operation on the development data of the areas to be developed to obtain spatial image data of each area to be developed, wherein there is a one-to-one correspondence between the spatial image data and the areas to be developed.
[0068] Optionally, in an optional embodiment of the present invention, the above-mentioned preset GIS spatial analysis algorithm can be an analysis method based on a geographic information system (GIS). The preset GIS spatial analysis algorithm can generate an image containing complex data such as geographic spatial information and implicit information based on the spatial location data and indicator data of the geographic object. This is to assist in relevant decision-making. The present invention introduces a preset GIS spatial analysis algorithm to establish a correspondence between the scope of the to-be-developed area and the development data of the to-be-developed area by combining the acquired development data with the spatial image of the to-be-developed area through multi-layer overlay analysis. Compared with the existing technology, the present invention can establish a correspondence between development data and the to-be-developed area by assigning relevant data based on the subjective cognition of experts, thereby ensuring the accuracy of calculating the solar energy resource development potential score of each to-be-developed area.
[0069] Optionally, in another optional embodiment of the present invention, the above-mentioned spatial coordinates may be the longitude and latitude coordinates of the area to be developed.
[0070] Optionally, in another optional embodiment of the present invention, the above-mentioned spatial image data may be a digital map of the area to be developed carrying development data.
[0071] S103. Based on the spatial image data, a preset entropy weight algorithm is used to calculate the solar energy resource development potential score of each area to be developed.
[0072] Optionally, in an optional embodiment of the present invention, the aforementioned preset entropy weighting algorithm (The Entropy Method) is used to determine the degree of dispersion of a certain indicator in an event. The greater the degree of dispersion of the indicator, the greater the impact of the indicator on the event. This degree of dispersion can be reflected by the entropy value. By introducing the entropy weighting method, the present invention transforms the prior art method of subjective manual judgment of data into an objective method based on mathematical calculations of the data. This improves data utilization while enhancing the objectivity and accuracy of the final analysis results.
[0073] This invention introduces a pre-set GIS spatial analysis algorithm to combine acquired development data with spatial images of the undeveloped area through a multi-layer overlay analysis method, establishing a correspondence between the scope of the undeveloped area and the development data for that area. Compared to the prior art, this invention uses an expert's subjective knowledge to assign relevant data values, thereby establishing a correspondence between development data and undeveloped areas, thereby ensuring the accuracy of calculating the solar resource development potential score for each undeveloped area. Furthermore, by introducing the entropy weight method, this invention transforms the prior art's manual and subjective data assessment method into an objective method based on mathematical calculations based on the data. This improves data utilization while enhancing the objectivity and accuracy of the final analysis results. Finally, this invention analyzes and screens undeveloped areas from multiple perspectives: solar resource data, permitted area data, and surrounding environmental data. Compared to the prior art's method of dividing development areas into entire areas, this invention improves the accuracy of the data used to calculate the solar resource development potential score while maintaining computational efficiency. Thus, this invention achieves the inventive goal of improving the accuracy of solar resource development potential assessments.

Based on the development data, areas to be developed are screened from each candidate area, including:
[0075] The solar resource data of the candidate area is evaluated using a preset solar resource assessment model to obtain the solar energy utilization rate of the candidate area. The permitted area data of the candidate area is analyzed using a preset terrain analysis model to obtain the terrain suitability of the candidate area. The surrounding environment data of the candidate area is analyzed using a preset surrounding feature analysis model to obtain the economic suitability of the candidate area.
[0076] Alternatively, in an optional embodiment of the present invention, the data type of the solar energy utilization rate may be a solar energy exploitation coefficient. The data type of the terrain suitability may include: aspect, slope, and land exploitation rate. The data type of the economic suitability may include: distance to the transportation network, distance to existing power stations, photovoltaic power station electricity cost, and annual carbon emissions of the power station.
[0077] Optionally, in another optional embodiment of the present invention, the above-mentioned preset comprehensive analysis model is as follows: Figure 2As shown, it can include a solar resource assessment model, a terrain analysis model, a power plant annual carbon emission reduction model, a road network distance estimation model, and a kilowatt-hour cost estimation model. The specific model type can be determined according to the actual application scenario and is not limited in this invention.
[0078] Based on solar energy utilization, terrain suitability and economic suitability, areas to be developed are selected from various alternative areas.
[0079] In order to illustrate the process of screening out the areas to be developed, Figure 3 A specific embodiment of the present invention is shown for explanation:
[0080] Step S301 , using a preset comprehensive analysis model, calculates the solar energy utilization rate, terrain suitability and economic suitability of the candidate area, and triggers step S302 .
[0081] Step S302: Determine whether the solar energy utilization rate of the candidate area is greater than a first preset threshold. If yes, step S303 is triggered; if no, step S306 is triggered.
[0082] Step S303: Determine whether the terrain suitability of the candidate area is greater than a second preset threshold. If yes, step S304 is triggered; if no, step S306 is triggered.
[0083] Step S304: Determine whether the economic suitability of the candidate area is greater than a third preset threshold. If yes, step S305 is triggered; if no, step S306 is triggered.
[0084] Step S305: determine the candidate area as the area to be developed, and end the process.
[0085] Step S306: Delete the candidate area.
