More specifically, the invention relates to an offshore wind farm site selection system and method configured to integrate and provide various data related to offshore wind farm site selection and to derive an optimal offshore wind farm site by analyzing the data according to the environment and various requirements set by the user, in order to solve the problems of conventional offshore wind farm site selection methods, which generally involve the selection of sites for the development of offshore wind farms, where data is dispersed among various institutions such as the government, various research institutes, and private sectors, making integrated and efficient site analysis difficult; furthermore, where site selection is carried out by analyzing each element individually and synthesizing them manually, resulting in high time and cost, as well as limitations in objectively evaluating the complex effects of various factors.

[0003] Furthermore, the present invention relates to an offshore wind farm site selection system and method configured to solve the problems of conventional offshore wind farm site selection methods, which, as mentioned above, are difficult to perform integrated and efficient site analysis due to data being dispersed among various institutions, and which have limitations such as requiring significant time and cost and being difficult to objectively evaluate the complex impact of various factors due to the method of analyzing each element individually and synthesizing them manually.

Background Technology

[0005] Recently, as environmental issues have emerged as a global concern, interest in and demand for eco-friendly power generation, such as wind power, are increasing. Among these, offshore wind power is seeing rising interest and demand due to its advantages over onshore wind power, including fewer site constraints and the ability to secure high-quality wind resources.

[0007] Here, in order to generate electricity through offshore wind power, an offshore wind farm capable of installing multiple offshore wind power facilities must be established, and to this end, a site with an appropriate location and size suitable for offshore wind power generation must first be selected.

[0009] Accordingly, as presented, for example, in the "Wind Power Plant Simulator Considering Environmental Impact Assessment" of Korean Registered Patent Publication No. 10-2222817 and the "Offshore Wind Power Site Selection System and Offshore Wind Power Site Selection Method Using the Same" of Korean Published Patent Publication No. 10-2024-0086160, various devices and methods have been proposed in the past for selecting the site of an offshore wind power plant; however, the contents of the prior art described above had the following limitations.

[0011] More specifically, as mentioned above, offshore wind power generation generally has the advantage of fewer site constraints and the ability to secure high-quality wind resources compared to onshore wind power generation; however, recently, conflicts among stakeholders are intensifying due to issues such as indiscriminate preemptive development, the undervaluation of marine resources, and limitations in analysis caused by the dispersion of information.

[0013] Furthermore, unlike overseas markets, domestic offshore wind power is characterized by the fact that operators must directly select sites. Consequently, there is a growing need for site selection technology that can be utilized for government-led offshore wind site selection under the Special Act on Offshore Wind Power; however, in reality, there have been limitations in conducting integrated site analysis because data held by various institutions—including the government, research institutes, and the private sector—is fragmented.

[0015] In addition, with the recent surge in demand for renewable energy driven by global companies' RE100 declarations and the goal of achieving carbon neutrality by 2050, and the government's Renewable Energy 3020 policy requiring an expansion of the share of new and renewable energy generation to 20% by 2030, efficient site selection and development of offshore wind power generation have emerged as urgent tasks.

[0017] However, generally speaking, existing site selection methods mostly involve analyzing individual elements separately and synthesizing them manually; consequently, this approach not only requires significant time and cost but also has limitations in that it is difficult to objectively evaluate the complex impact of various factors.

[0019] Furthermore, the aforementioned prior art only presented the selection of a site by reflecting environmental impacts, and did not present any content for solving the problems of the existing site selection method mentioned above.

[0021] Therefore, in order to resolve the limitations of the conventional offshore wind farm site selection method described above, it is desirable to present a new offshore wind farm site selection system and method configured to integrate various data related to offshore wind farm site selection dispersed across different institutions and provide them in a customized manner according to user requirements, while simultaneously deriving the optimal offshore wind farm site based on the environment and various requirements set by the user; however, a device or method that satisfies all such requirements has not yet been presented. Prior art literature

[0024] The present invention aims to solve the problems of the prior art as described above. Accordingly, the objective of the present invention is to present a system and method for selecting an offshore wind farm site that integrates and provides various data related to offshore wind farm site selection, and is configured to derive the optimal offshore wind farm site by analyzing data according to the environment and various requirements set by the user. This is done to address the limitations of the prior art method, which generally makes integrated and efficient site analysis difficult because data is dispersed among various institutions such as the government, research institutes, and private sectors, and furthermore, because site selection is carried out by analyzing each element individually and synthesizing them manually, resulting in high time and cost, as well as difficulty in objectively evaluating the complex effects of various factors.

[0026] Furthermore, another objective of the present invention is to present an offshore wind farm site selection system and method configured to solve the problems of conventional offshore wind farm site selection methods, which, as mentioned above, are difficult to perform integrated and efficient site analysis due to data being dispersed among various institutions, and which suffer from the limitations of requiring significant time and cost and being difficult to objectively evaluate the complex impact of various factors resulting from the method of analyzing each element individually and synthesizing them manually. This is achieved by constructing a framework that considers various evaluation factors necessary for offshore wind farm site selection and applying user-customized settings to utilize an exclusion analysis method that excludes areas with poor site conditions or those ineligible for site selection under current regulations. By configuring the system to derive the optimal site according to step-by-step options set by the user, while automatically selecting the optimal offshore wind farm site based on the analysis environment and various requirements set by the user, the system can integrate various data related to offshore wind farm site selection and provide it in a customized manner according to the user's request, thereby aiding in efficient decision-making during the early stages of offshore wind farm development. means of solving the problem

Specific details for implementing the invention

[0059] Hereinafter, specific embodiments of the offshore wind farm site selection system and method according to the present invention will be described with reference to the attached drawings.

[0061] Hereinafter, it should be noted that the following description is merely one embodiment for carrying out the present invention, and the present invention is not limited only to the contents of the embodiment described below.

[0063] In addition, it should be noted that in the following description of the embodiments of the present invention, detailed descriptions of parts that are identical or similar to the prior art or that are deemed to be easily understood and implemented by those skilled in the art have been omitted for the sake of brevity.

[0065] Next, with reference to the drawings, specific details of the offshore wind farm site selection system and method according to the present invention will be described.

[0067] More specifically, first, referring to FIG. 1, FIG. 1 is a block diagram schematically showing the overall configuration of an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0069] As shown in FIG. 1, the offshore wind farm site selection system (10) according to an embodiment of the present invention may be broadly configured to include a data collection unit (11) that performs processing to collect various predetermined data for offshore wind farm site selection, a site selection unit (12) that performs processing to select an optimal offshore wind farm site suitable for requirements input by a user according to a predetermined setting based on each data collected through the data collection unit (11), and provides various information related to offshore wind farm site selection in a customized manner according to the user's request or the predetermined setting, and an output unit (13) that performs processing to output various data including the data collected through the data collection unit (11) and the processing contents and results of the site selection unit (12) according to a predetermined setting or the user's request.

[0071] Here, the offshore wind farm site selection system (10) according to an embodiment of the present invention may further comprise a communication unit (14) for transmitting and receiving various data by communicating with an external device in at least one of wired or wireless communication as shown in FIG. 1, a database unit (15) for performing a process to build a database related to site selection for each offshore wind farm by storing each data obtained from each processing process and processing result, and a control unit (16) for performing a process to control the overall operation of each unit and the offshore wind farm site selection system (10).

[0073] In addition, the above-mentioned data collection unit (11) may be configured to perform a process of directly receiving various data predetermined for the selection of an offshore wind farm site, such as fixed or floating types of offshore wind turbines to be installed, along with data in various fields related to marine space, such as geographic information including map data for each region, environmental information including wind conditions, water depth, fishery resources, marine ecosystems, etc., and regulatory information including various licensing information, regulated areas, and military areas, etc., through a separate input means.

[0075] Alternatively, the data collection unit (11) described above may be configured to perform a process of receiving each data from an external device according to a predetermined setting, such as a user terminal or a server, instead of directly receiving each data.

[0077] In addition, the above-mentioned site selection unit (12) may be configured to perform a process of selecting an optimal offshore wind farm site that meets the user's requirements according to a predetermined setting, based on data collected through the data collection unit (11) as described below, and considering the perspectives of stakeholders in various fields such as wind conditions, water depth, seabed topography, fishing activities, maritime traffic, economic feasibility, grid connection, etc., and a process of providing various information related to the offshore wind farm site selection in a customized manner according to the user's request or a predetermined setting.

[0079] More specifically, referring to FIG. 2, FIG. 2 is a flowchart schematically showing the overall processing performed in the site selection unit (12) of the offshore wind farm site selection system (10) according to the embodiment of the present invention shown in FIG. 1.

[0081] As shown in FIG. 2, the above-mentioned site selection unit (12) first retrieves map data corresponding to the area where site selection is to be performed from the data collected through the data collection unit (11) to display various information and processing results processed through the site selection process, sets it as a basic map, and sets the analysis range by reflecting the territorial sea, coastline, boundary line, various water body information and regulation zone information on the set basic map (S10).

[0083] Next, analysis conditions for site selection are set by reflecting major consideration factor information and additional consideration factor information, respectively, according to the generator installation method (fixed type, floating type) set by the user (S20).

[0085] Here, the site selection area and generator installation method can be configured to be input by the user, and information on various consideration factors can also be configured to be input by selecting each item step by step.

[0087] That is, for example, regarding water depth, one of shallow, normal, or deep depth can be selected and entered; regarding wind speed, one of high, medium, or low wind speed can be selected and entered; and regarding fishery density, one of the upper, middle, or lower fishery density ranges can be selected and entered.

[0089] Next, the system can be configured to perform a pre-set preprocessing on the base map to convert it into a grid form (S30), and then, according to the generator installation method set by the user, to reflect the analysis range information (territorial sea, coastline, boundary line, various water body information and regulated area information) set on the base map, as well as the information on major consideration factors and additional consideration factors, to perform an analysis according to the pre-set settings, and to select the optimal location that meets each condition to provide the location selection result (S40).

[0091] More specifically, with reference to FIGS. 3 and FIGS. 4, FIG. 3 is a conceptual diagram schematically showing an example of the actual configuration of the overall processing of the site selection unit (12) shown in FIG. 2, and FIG. 4 is a conceptual diagram schematically showing an example of the configuration of the overall processing of an offshore wind farm site selection system according to an embodiment of the present invention.

[0093] As shown in FIGS. 3 and 4, according to the present invention, each consideration factor set by the user is collected to set the analysis range and conditions for the basic map, and after performing preprocessing to convert the basic map into a grid form, an analysis is performed by reflecting each consideration factor set by the user, and a result is provided.

[0095] To this end, in order to limit the scope of analysis, 20 layers such as boundary lines and water bodies were selected as basic maps, and layers from various fields related to marine space, including fishery resources, marine ecosystems, energy resources, and marine environment, were collected to identify factors to consider.

[0097] That is, the above-mentioned basic map is composed of approximately 20 map layers that serve as the basis for spatial information, and may include information such as territorial waters, cadastral lines, straight baselines, Korea-China transitional waters, Korea-Japan intermediate waters, maritime firing training zones, and maritime traffic networks to distinguish items or boundaries that may be subject to inter-departmental consultation in the future.

[0099] Furthermore, regarding generator installation methods, offshore wind power can be broadly classified into fixed and floating types based on the turbine installation method, as seen in the application of fixed jacket-type generators utilizing turbines at the Tamra and Southwest Sea demonstration complexes, and the planned application of floating semi-submersible generators at the Ulsan Floating Offshore Wind Farm. Since the scope of data that must be considered differs accordingly, the framework can be configured to derive different results through classification at the beginning to reflect these details in site selection.

[0101] In addition, matters where specific activities are restricted or require permission for the purpose of protection or development are designated as 'regulated zones' to enable the identification of legal matters. Specifically, the regulated zone information is information regarding zones where activity restrictions or consultation are legally specified in relation to offshore wind power generation, and can be composed of legal reviews and spatial information for 36 layers including, for example, marine protected areas, coastal wetland protected areas, World Heritage sites, conservation uninhabited islands, fisheries resource protection areas, park areas, fixed net fishing areas, etc.

[0103] Furthermore, wind speed and water depth data were selected as key elements in the offshore wind site selection process as major consideration factors. Additionally, the system is configured to allow users to directly consider additional factors or set step-by-step options; for instance, wind power operators can select and set offshore wind power generation business permits and the installation locations of wind measurement equipment as consideration factors, while fishermen can set fishing density and catch volume as consideration factors with high weighting.

[0105] In addition, in the present invention, map data corresponding to spatial data in the form of points, lines, and planes is converted into a 1-minute grid (width × height approximately 1.8 km) and an exclusion analysis method is applied by overlaying grids to exclude areas with poor location conditions or areas that cannot be located under the current system.

[0107] In addition, the analysis results display areas where offshore wind turbines can be installed on a map by summing the factors selected by the user, and furthermore, depending on predetermined settings or user selection, they can be configured to be provided in various forms or formats, such as tables, graphs, drawings (.png), and reports (.pdf).

[0109] Here, the provision of analysis results can be configured to provide information on fishery density and catch volume by applying, for example, fishery analysis data from the National Federation of Fisheries Cooperatives. In addition, it can be configured to more accurately and in detail identify matters requiring consideration and consultation during site selection by overlaying and providing maritime firing training zones requiring consultation with the Ministry of National Defense and maritime traffic networks requiring consultation with the Ministry of Oceans and Fisheries' maritime traffic safety assessment at the information provision stage.

[0111] Therefore, from the configuration described above, the optimal offshore wind farm site can be derived according to various considerations set by the user, and each data can be visualized and displayed, while simultaneously providing integrated data related to the selection of the offshore wind farm site.

[0113] To this end, the output unit (13) described above may be configured to include a display means, such as a display for displaying various data, and to perform a process of outputting various data obtained from the respective processing steps and results of the data collection unit (11) and location selection unit (12) in a specific form or format according to a predetermined setting or a user's request, such as, for example, a table or graph, or a drawing or a specific file format.

[0115] Furthermore, the communication unit (14) described above may be configured to perform processing to transmit and receive various data by communicating with an external device in at least one of wired or wireless communication according to a predetermined setting, such as a user terminal or a server.

[0117] Here, the aforementioned user terminal may be composed of, for example, an information and communication terminal that is portable by an individual, such as a smartphone or tablet PC, or an information processing device, such as a PC or laptop.

[0119] In addition, the above-mentioned database unit (15) may be configured to store various data obtained from the overall processing and processing results of each unit and the offshore wind farm site selection system (10) and to perform a process of building a database related to details, etc. for each region.

[0121] In addition, the above-mentioned control unit (16) may be configured to control the overall operation of each unit and the offshore wind farm site selection system (10), and at the same time, perform processing to provide customized information in accordance with a user's request based on data stored in the database unit (15).

[0123] Accordingly, the offshore wind farm site selection system (10) according to the embodiment of the present invention can be implemented as described above. That is, referring to FIGS. 5 to 8, FIGS. 5 to 8 are conceptual diagrams schematically illustrating examples of the configuration of an offshore wind site information screen provided through the offshore wind farm site selection system according to the embodiment of the present invention.

[0125] Here, Fig. 5 is an example of the configuration of a screen for searching information on the details of offshore wind farm site selection, Fig. 6 is an example of the configuration of a setting screen for allowing a user to input and set various consideration factors, Fig. 7 is an example of the configuration of a map screen for offshore wind farm site selection, Fig. 8 is an example of the configuration of a report screen for outputting the results of offshore wind farm site selection, and Windspot refers to a user-customized site analysis tool.

[0127] As shown in FIGS. 5 to 8, according to the present invention, a framework is constructed by considering various evaluation factors required for site selection of an offshore wind farm, and the most suitable optimal site is selected by using an exclusion analysis method that excludes areas with poor site conditions or areas that cannot be located under current regulations by applying user-customized settings. To this end, spatial information having the form of points, lines, and planes is preprocessed into a 1-minute grid unit (width × height approximately 1.8 km) as an evaluation factor for spatial analysis of the exclusion method.

[0129] More specifically, referring to FIG. 9, FIG. 9 is a diagram showing an example of the configuration of an analysis target sea area set for selecting a location of an offshore wind farm in an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0131] As shown in FIG. 9, in an embodiment of the present invention, first, for the site selection of an offshore wind farm, a sea area to be analyzed (i.e., the red part of FIG. 9) is set based on the range where a wind map can be calculated and the range considering the power system, and this sea area is represented by a GIS-based vector polygon and is considered as a region where fixed and floating offshore wind farm sites can be selected, and the site selection is performed using a three-stage filtering method as described below, and in each stage, a spatial area corresponding to a specific exclusion condition is removed.

[0133] More specifically, first, for filtering regulated areas, data regarding restricted activity areas, areas requiring consultation, marine protected areas, military facility areas, sea routes, etc. are collected through the data collection unit (11).

[0135] Next, the site selection unit (12) performs a process to calculate the area (S1) from which the regulated area is excluded by excluding the regulated area from the entire sea area to be analyzed based on the data collected through the data collection unit (11), as shown in [Mathematical Formula 1] below.

[0137] [Mathematical Formula 1]

[0138] S1 = Ω - R1

[0140] (Here, Ω represents the entire analysis area (1-minute grid interval, latitude 30˚–39˚ / longitude 122˚–135˚), and R1 represents the set of regulated areas (1-minute grid interval).)

[0142] In addition, referring to FIG. 10, FIG. 10 is a diagram showing a table summarizing examples of environmental conditions regarding wind speed and water depth applied as major consideration factors for selecting a location of an offshore wind farm in an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0144] As shown in FIG. 10, the above-mentioned site selection unit (12) calculates a regulated area and a sea area (S2) from which environmental conditions are excluded by applying three stages of conditions to wind speed and water depth as major consideration factors, respectively, according to the fixed / floating wind turbine installation method. This processing process can be represented as [Equation 2] to [Equation 4] below, and each grade can be configured to allow for multiple selections, and the specific conditions can be configured as shown in FIG. 10.

[0146] [Mathematical Formula 2]

[0147]

[0149] [Mathematical Formula 3]

[0150]

[0152] [Mathematical Formula 4]

[0153] S2 = S1 ∩ (R2 ∩ R3)

[0155] (Here, R2 represents the space excluded for wind speed, and R3 represents the space excluded for water depth, respectively.)

[0157] Continuing, referring to FIG. 11, FIG. 11 is a diagram showing a table summarizing an example of the configuration of consideration conditions for each item applied as an additional consideration factor for selecting the location of an offshore wind farm in an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0159] As shown in FIG. 11, the above-mentioned site selection unit (12) may be configured to selectively include or exclude the status of power generation business permits and measuring instruments related to offshore wind power as additional consideration factors, and additionally, may be configured to include or exclude fishing density and catch volume related to fishing activities by applying three-stage conditions to each.

[0161] More specifically, let R4 be the space excluded from power generation business licenses and S3 be the sea area excluded from additional consideration factors for power generation business licenses, R5 be the space excluded from measuring instruments and S4 be the sea area excluded from additional consideration factors for measuring instruments, R6 be the space excluded from fishery density, R7 be the space excluded from catch volume, and S5 be the sea area excluded from additional consideration factors for fishery density and catch volume. Each sea area can be represented as [Equation 5] below.

[0163] [Mathematical Formula 5]

[0164] S3 = S2 - R4 (0 if R4 is not considered)

[0165] S4 = S3 - R5 (0 if R5 is not considered)

[0166] R6= (E low ∪ E mid ∪ E high )

[0167] R7= (C low ∪ C mid ∪ C high )

[0168] S5 = S4 ∩ (R6 ∩ R7)

[0170] Also, referring to FIG. 12, FIG. 12 is a diagram showing a table of regulatory zone information applied as a basic consideration factor for selecting the location of an offshore wind farm in an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0172] That is, a regulated zone refers to an area where restrictions on activities or consultation are legally specified for the construction of an offshore wind farm (subject to change depending on amendments and enactments of laws). Specifically, an activity restriction zone refers to a case where it is specified as 'no one is allowed,' a permit-requiring zone refers to a case where it is possible upon permission / approval by a metropolitan local government or the head of a city, county, or district, and a consultation-possible zone refers to a case where it is legally permissible or where no restrictions are specified. As shown in Fig. 12, in the present invention, 36 layers corresponding to regulated zones were selected and applied out of approximately 200 or more spatial information layers.

[0174] Based on the above, according to the present invention, an optimal location is derived according to step-by-step options set by a user by considering location factors from the perspective of stakeholders in various fields, such as wind conditions, water depth, seabed topography, fishing activities, maritime traffic, economic feasibility, and grid connection, for example. At this time, it is expected that decision-making in the early stages of offshore wind farm development can be supported more efficiently by not only immediately displaying each element input by the user for location selection visually, but also providing the processing results in various forms such as drawings and reports.

[0176] Accordingly, as described above, an offshore wind farm site selection system (10) according to an embodiment of the present invention can be implemented, and by using this, an offshore wind farm site selection method configured to select an optimal offshore wind farm site that meets the user's requirements by reflecting consideration requirements for various fields can be easily implemented.

[0178] That is, referring to FIG. 13, FIG. 13 is a flowchart schematically showing the overall configuration of a method for selecting a site for an offshore wind farm according to an embodiment of the present invention.

[0180] As shown in FIG. 13, the method for selecting an offshore wind farm site according to an embodiment of the present invention may be broadly divided into a data collection step (S10) in which a process of collecting various predetermined data for selecting an offshore wind farm site is performed through a data collection unit (11) of the offshore wind farm site selection system (10) described above; a site selection step (S20) in which a process of selecting an optimal offshore wind farm site suitable for requirements input by a user according to a predetermined setting based on each data collected through the data collection step (S10) is performed through a site selection unit (12) of the offshore wind farm site selection system (10) described above; and an information provision step (S30) in which a process of outputting and providing corresponding information in a designated format or form according to a predetermined setting and a user's request based on information generated through the site selection step (S20) is performed through an output unit (13) of the offshore wind farm site selection system (10) described above.

[0182] Here, regarding the more specific details of the processing steps of each step described above, it should be noted that the offshore wind farm site selection system (10) according to the embodiment of the present invention described above can be configured in the same or similar manner with reference to FIGS. 1 to 12, and therefore, in order to keep the explanation brief, detailed descriptions of overlapping content have been omitted here.

[0184] Accordingly, from the above-described content, the offshore wind farm site selection system (10) and method according to the embodiment of the present invention can be easily implemented, and by using this, the offshore wind farm information provision system (20) and method can be easily implemented, which is configured to provide desired information in real time according to the user's request by integrating information for a wide area, such as a nationwide area, for example.

[0186] That is, referring to FIG. 14, FIG. 14 is a block diagram schematically showing the overall configuration of an offshore wind farm information provision service system (20) configured using an offshore wind farm site selection system (10) according to an embodiment of the present invention.

[0188] As shown in FIG. 14, the offshore wind farm information provision service system (20) according to an embodiment of the present invention may be broadly configured to include an information provision unit (21) that is installed in each region to collect various data predetermined for offshore wind farm site selection, selects an optimal offshore wind farm site suitable for requirements input by a user according to predetermined settings based on the collected data, and performs processing to provide various information related to offshore wind farm site selection in a customized manner according to the user's request or predetermined settings; a user terminal (22) for requesting and receiving services desired by each user; and a service server (23) that is linked with each information provision unit (21) and user terminal (22) to collect information from each information provision unit (21), builds a database related to offshore wind farms and site selection in each region, and performs processing to provide various information in a customized manner through the user terminal (22) according to the user's request received through the user terminal (22).

[0190] Here, the information providing unit (21) described above may be configured to be identical or similar to the offshore wind farm site selection system (10) according to an embodiment of the present invention configured as described above with reference to FIGS. 1 to 12, and it should be noted that detailed descriptions of redundant content have been omitted here for the sake of brevity.

[0192] In addition, the above-mentioned user terminal (22) can preferably be configured using an information and communication terminal that is portable by an individual, such as a smartphone or tablet PC, or an information processing device such as a PC or laptop, and thereby can be configured with a relatively simple configuration and low cost without the need to implement separate hardware.

[0194] In addition, in the above-described embodiment of the present invention, the invention was described by citing an example in which map data, environmental information such as wind speed and water depth, and regulatory information are collected for each region, and an analysis is performed in real time according to the type of offshore wind turbine and various consideration factors set by the user to select the optimal offshore wind farm location and provide various information. However, the present invention is not necessarily limited to the contents presented in the embodiment. That is, in addition to the configuration presented in the above-described embodiment, the present invention may be configured to automatically perform processing to select the optimal offshore wind farm location in real time from various data and requirements input by the user and provide various information customized according to the user's request, by using, for example, an artificial intelligence (AI) algorithm such as machine learning or deep learning, or an artificial intelligence model based on an artificial neural network (ANN) or a convolutional neural network (CNN).

[0196] More specifically, it should be noted that the present invention may be configured to be modified and changed in various ways by those skilled in the art as needed within the scope of the spirit and essence of the invention, for example, by utilizing Generative Artificial Intelligence (Generative AI) technology or multimodal processing models to interpret various data and requirements input by a user and propose optimal candidate sites for offshore wind farms in real time based thereon, while simultaneously automatically generating and providing relevant information (characteristics of candidate sites, constraints, legal regulations, etc.) in various formats upon the user's request.

[0198] Furthermore, regarding the more specific details of the processing process for collecting various predetermined data for offshore wind farm site selection and selecting the optimal offshore wind farm site that meets each requirement based on the collected data in the above-described embodiment of the present invention, since this is a matter that can be appropriately implemented by a person skilled in the art by referring to the contents of offshore wind farm site selection systems and methods of the prior art, it should be noted that, in order to simplify the explanation, the detailed description of the present invention has been omitted regarding content that is obvious to a person skilled in the art from the prior art as described above, or content that a person skilled in the art can easily understand and implement by referring to prior art literature, etc.

[0200] Accordingly, as described above, an offshore wind farm site selection system and method according to an embodiment of the present invention can be implemented. By doing so, according to the present invention, a framework is constructed by considering various evaluation factors required for offshore wind farm site selection, and by applying user-customized settings and utilizing an exclusion analysis method that excludes areas with poor site conditions or those that cannot be located under current regulations, the system is configured to derive an optimal site based on step-by-step options set by the user by considering site factors from the perspective of stakeholders in various fields. Consequently, the optimal offshore wind farm site is automatically selected according to the analysis environment and various requirements set by the user, and at the same time, various data related to offshore wind farm site selection can be integrated and provided in a customized manner according to the user's request. This can assist in efficient decision-making during the early stages of offshore wind farm development. Furthermore, this can resolve the problems of conventional offshore wind farm site selection methods, which had limitations such as difficulty in integrated and efficient site analysis due to data being dispersed among different institutions, high time and cost consumption resulting from the method of analyzing each element individually and synthesizing them manually, and difficulty in objectively evaluating the complex impact of various factors.

[0202] Although the details of the offshore wind farm site selection system and method according to the present invention have been described above through the embodiments of the present invention, the present invention is not limited only to the contents described in the above embodiments. Therefore, it is obvious that the present invention can be modified, changed, combined, and substituted in various ways by a person skilled in the art according to design needs and other various factors.
