However, in the planning of the structure optimization of the transmission system of offshore wind power clusters in the existing technology, if the laying path of the transmission cable is not optimized, it will increase the difficulty of cable maintenance and failure rate; if the location of the offshore booster platform is not properly selected, the transmission cable will need a longer distance to connect each wind turbine and the onshore power grid, thereby increasing the laying cost.

[0038] Figure 2 is a flow chart of a method for determining the structure of an offshore wind power cluster transmission system according to one embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0039] Step S20, obtaining the coordinates of multiple wind turbines in the offshore wind power cluster, the center coordinates of the onshore centralized control center, and regional restriction information;

[0040] In step S20, the coordinates of the above-mentioned multiple wind turbines are used to characterize the precise geographic location coordinates of the wind turbines. For example, a high-precision global positioning system (GPS) or geographic information system (GIS) technology is used to determine the precise location of each wind turbine. These technologies can provide longitude and latitude coordinates, and even altitude information, to ensure the accuracy of the wind turbine location.

[0041] The central coordinates of the above-mentioned onshore centralized control center are used to represent the central coordinates of the onshore centralized control center closest to the offshore wind power cluster, expressed in longitude and latitude.

[0042] The above regional restriction information is used to characterize the geographical and environmental constraints of the offshore wind power cluster transmission system to ensure that the design and construction of the transmission cables meet safety, environmental protection and technical standards. The above regional restriction information includes but is not limited to: seabed topography and water depth, environmental protection areas and ecologically sensitive areas.

[0043] Step S22, determining candidate coordinates of the offshore boost platform based on the coordinates and center coordinates of the plurality of wind turbines;

[0044] Step S24, determining a first transmission cable laying path and a target coordinate of the offshore boosting platform based on the candidate coordinates and the area restriction information, wherein the first transmission cable laying path is used to represent a transmission cable laying path between the wind farm cluster and the offshore boosting platform;

[0045] Specifically, the Ant Colony Optimization (ACO) algorithm is used to search between the candidate coordinates and the coordinates of multiple wind turbines in combination with the regional restriction information to obtain the candidate transmission cable laying path corresponding to each candidate coordinate. Multiple candidate transmission cable laying paths are screened to determine the first transmission cable laying path, and the candidate coordinates corresponding to the first transmission cable laying path are determined as the target coordinates of the offshore booster platform. At the same time, the low-voltage cable laying path and the low-voltage confluence cable laying path are determined according to the first transmission cable laying path, and the shortest path from other wind turbines to the low-voltage confluence cable is determined.

[0046] Step S26, determining a second transmission cable laying path based on the center coordinates and the target coordinates, wherein the second transmission cable laying path is used to represent a transmission cable laying path between the offshore boosting platform and the onshore centralized control center;

[0047] Specifically, the ACO algorithm is used in combination with the area restriction information to search between the central coordinates and the target coordinates of the onshore centralized control center to obtain the shortest path between the central coordinates and the target coordinates, and the shortest path is determined as the second transmission cable laying path.

[0048] Step S28, determining the offshore wind power cluster transmission system structure based on the first transmission cable laying path, the second transmission cable laying path and the target coordinates.

[0049] Specifically, the low-voltage cable laying path and the low-voltage converging cable laying path between the offshore booster platform and the offshore wind farm cluster are determined based on the first transmission cable laying path, and the transmission cable laying path between the onshore centralized control center and the offshore booster platform is determined based on the second transmission cable laying path. In summary, the offshore wind farm cluster transmission system structure is determined.

[0050] Based on the above steps S20 to S28, the coordinates of multiple wind turbines in the offshore wind power cluster, the central coordinates of the onshore centralized control center and the regional restriction information are obtained, and based on the coordinates and the central coordinates of the multiple wind turbines, the candidate coordinates of the offshore booster platform are determined; based on the candidate coordinates and the regional restriction information, the first transmission cable laying path and the target coordinates of the offshore booster platform are determined; based on the central coordinates and the target coordinates, the second transmission cable laying path is determined; based on the first transmission cable laying path, the second transmission cable laying path and the target coordinates, the transmission system of the offshore wind power cluster is determined The structure achieves the purpose of optimizing the site selection of the offshore booster platform and the laying path of the transmission cable by comprehensively considering the site selection of the offshore booster platform and the laying path of the transmission cable, thereby achieving the technical effect of comprehensively considering the geographical environment of the offshore wind farm and the site selection of the offshore booster platform to reduce the cable laying cost and operation and maintenance complexity of the offshore wind power cluster transmission system, thereby solving the technical problem of high transmission cable laying cost and high operation and maintenance complexity of the offshore wind power cluster transmission system due to failure to comprehensively consider the site selection of the offshore booster platform and the laying path of the transmission cable in the related technology.

[0051] Optionally, in step S22, determining candidate coordinates of the offshore boost platform based on the coordinates and center coordinates of the plurality of wind turbines includes:

[0052] Step S221, connecting the coordinates of the multiple wind turbines with the center coordinates to form multiple test straight lines;

[0053] Step S222, dividing the plurality of test straight lines into equal distances to obtain a plurality of equal distance lines;

[0054] Step S223: determine the midpoints of the multiple equidistant lines as candidate coordinates.

[0055] Specifically, Figure 3 is a schematic diagram of a method for determining the structure of an offshore wind power cluster transmission system according to one embodiment of the present invention, such as Figure 3As shown: the hollow circles represent the coordinates of multiple wind turbines, and the solid circles represent the central coordinates of the onshore centralized control center. As shown in the figure, the wind turbines include: wind turbine 1, wind turbine 2, wind turbine 3 and wind turbine 4, and the candidate coordinates include: candidate coordinate A, candidate coordinate B, ..., candidate coordinate G. First, the coordinates of each wind turbine are connected to the central coordinates of the centralized control center to form multiple test lines; then, each test line is divided into equal intervals, and the same equal interval points on each test line are connected to obtain multiple equal interval lines; then, the midpoints of the multiple equal interval lines are used as candidate coordinates of the offshore booster platform, where the lines between the midpoints are detection line segments. In the process of equal interval division, selecting the midpoint as the candidate coordinate helps to reduce the differences in the transmission paths from multiple wind turbines to the offshore booster platform, thereby improving the balance of power transmission and optimizing the transmission efficiency and stability of electric energy.

[0056] Based on the above steps S221 to S223, the coordinates of the multiple wind turbines are respectively connected to the central coordinates to form multiple test straight lines; the multiple test straight lines are equally spaced to obtain multiple equidistant lines; the midpoints of the multiple equidistant lines are determined as the candidate coordinates, which can ensure that the location selection of the offshore booster platform can fully consider the distribution of each wind turbine, avoid placing the offshore booster platform in a too remote or unreasonable location, and optimize the spatial layout of the offshore booster platform.

[0057] Optionally, in step S24, determining the first transmission cable laying path and the target coordinates of the offshore boosting platform in the offshore wind power cluster transmission system based on the candidate coordinates and the area restriction information includes:

[0058] Step S241, searching between the candidate coordinates and the coordinates of multiple wind turbines using an ant colony algorithm in combination with the area restriction information to obtain a candidate transmission cable laying path;

[0059] In step S241, the ant colony algorithm is a heuristic algorithm that simulates the foraging behavior of ants in nature and is used to solve the path optimization problem.

[0060] Specifically, the map between the wind turbine coordinates and the candidate coordinates is gridded, and each edge in the gridded map represents a possible transmission cable laying path, and each edge has pheromone concentration and heuristic data associated with it. The ants are simulated to search for paths on the graph, and the probability of the ants choosing a path depends on the pheromone concentration and heuristic data, where the heuristic data is determined based on the regional restriction information. After multiple iterations, the ACO algorithm gradually finds a better path from the wind turbine to the offshore boost platform. After each iteration, the pheromone concentration on the path is updated according to the quality of the path found by the ants to provide feedback for subsequent iterations. According to the ACO algorithm, a better candidate transmission cable laying path corresponding to each candidate coordinate is obtained. Figure 3As shown in , based on the ACO algorithm, the preferred candidate transmission cable laying paths between the candidate coordinates A, the candidate coordinates B, ..., the candidate coordinates G and the wind turbine coordinates are obtained respectively.

[0061] Step S242, screening the candidate transmission cable laying paths to obtain the first transmission cable laying path and the target coordinates.

[0062] Specifically, multiple candidate transmission cable laying paths are screened according to the laying cost of the transmission cable, and the candidate transmission cable laying path with the lowest laying cost of the transmission cable is selected as the first transmission cable laying path, and the candidate coordinates corresponding to the candidate transmission cable laying path are determined as the target coordinates, that is, the site selection location of the offshore boost platform.

[0063] Based on the above steps S241 to S242, the ant colony algorithm is used in combination with the area restriction information to search between the candidate coordinates and the coordinates of multiple wind turbines to obtain candidate transmission cable laying paths; the candidate transmission cable laying paths are screened to obtain the first transmission cable laying path and the target coordinates, and by screening the candidate transmission cable laying paths, the path with the lowest cost is selected as the first transmission cable laying path, which can maximize resource savings and reduce construction costs while ensuring the power transmission effect.

[0064] Optionally, in step S241, the candidate transmission cable laying paths are obtained by searching between the candidate coordinates and the coordinates of the plurality of wind turbines using an ant colony algorithm in combination with the area restriction information, and the candidate transmission cable laying paths include:

[0065] Step S301, determining the candidate coordinates as food points;

[0066] Step S302, determining the coordinates of the plurality of wind turbines as an ant nest;

[0067] Specifically, the candidate location of the offshore booster platform is set as the “food point”, and the coordinates of multiple wind turbines are set as the “ant nest”. The goal of the ants is to find the optimal path from the food point to each ant nest.

[0068] Step S303, searching between the food point and the ant nest based on the probability transfer rule, the area restriction information and the objective function to obtain a candidate transmission cable laying path, wherein the objective function is determined based on the length of the transmission cable laying path.

[0069] In step S303, the above objective function is used to characterize the shortest path from the food point to the ant nest.

[0070] The specific calculation process of the above probability transfer rule is shown in expressions (1)-(2).

[0071]

[0072] in, m represents the number of ants; ρ represents the pheromone evaporation rate; α represents the pheromone importance factor; β represents the heuristic data importance factor; τ ij represents the pheromone intensity between the two grid points i and j, initialized to a constant; η ij Represents the heuristic data between two grid points i and j, usually inversely proportional to the distance; S∈A k represents the set of next grid points that ant k can reach from its current position (excluding obstacles); L k represents the length of the path traversed by ant k; Q is a constant.

[0073] Furthermore, the search area is divided into a series of smaller, regular grids, and the center point of each grid is called a grid point. ij reflects the attraction of the path, which represents the distance between two grid points, where the shorter the distance, the greater the ij The smaller the value of , the more attractive the path is to ants. However, when it is determined that there are obstacles on the path between two points based on the regional restriction information, the heuristic data is set to a maximum value (e.g., infinity) to indicate that this path is not selectable for ants, thereby ensuring that ants will not choose this path for search and guiding them to find other feasible paths.

[0074] For example, Figure 3 As shown in the figure, there are 7 candidate offshore booster platform locations (food points) A, B, C, D, E, F, G, and 4 wind turbines (ant nests): 1, 2, 3, and 4. There is a potential path between each wind turbine and each candidate location. Ants will start from the candidate location and find the shortest path to each wind turbine. Each ant moves according to the probabilistic transfer rule, which takes into account the pheromone concentration and heuristic data. Assuming that the ant starts from A, it will calculate the path to wind turbines 1, 2, 3, and 4, and choose the next moving direction based on the pheromone concentration and heuristic data of the path. After the ant completes a path search from the candidate location to the wind turbine, it will update the pheromone concentration along the way according to the length of the path. The shorter the path, the greater the increase in pheromone, so that other ants are more likely to choose this path in the next round of search. This process will be repeated many times until a termination condition is met, such as reaching a predetermined number of iterations or the path length no longer decreases significantly. After each iteration, the ant colony will update the pheromone, thereby gradually finding the optimal path set from the candidate location to the wind turbine.

[0075] Based on the above steps S301 to S303, the candidate coordinates are determined as food points; the coordinates of multiple wind turbines are determined as ant nests; based on the probability transfer rules, area restriction information and objective functions, a search is performed between the food points and the ant nests to obtain candidate transmission cable laying paths, wherein the objective function is determined based on the length of the transmission cable laying path. The ant colony algorithm can automatically complete the path selection process by simulating the behavior of nature, reduce human intervention, and improve the efficiency and intelligence level of path selection.

[0076] Optionally, in step S242, the candidate transmission cable laying paths are screened to obtain the first transmission cable laying path and the target coordinates, including:

[0077] Step S401, obtaining transmission cable laying cost information corresponding to the candidate transmission cable laying path;

[0078] Specifically, the intersections between the candidate transmission cable laying paths are obtained, and several candidate transmission cable laying paths with the most intersections are determined. The candidate coordinates are connected with each intersection in turn to obtain a transmission cable laying path, and the transmission cable laying path is determined as the laying path of the low-voltage confluence cable. The path between the last intersection (the intersection far away from the candidate coordinates) and the wind turbine is determined as the low-voltage cable laying path. According to the above transmission cable laying method, the transmission cable laying cost of several candidate transmission cable laying paths with the most intersections is calculated.

[0079] Furthermore, when there is no intersection between the candidate transmission cable laying paths, the path between the selected coordinate and the midpoint of the candidate transmission cable laying path is used as the laying path of the low-voltage merging cable, and the path between the midpoint and the wind turbine is used as the low-voltage cable laying path.

[0080] Step S402, screening candidate transmission cable laying paths based on the transmission cable laying cost information to obtain a first transmission cable laying path;

[0081] Step S403: determine the candidate coordinates corresponding to the first transmission cable laying path as the target coordinates.

[0082] Specifically, the transmission cable laying costs of several candidate transmission cable laying paths with the most intersections are obtained, and multiple candidate transmission cable laying paths are screened according to the transmission cable laying costs, and the candidate transmission cable laying path with the lowest transmission cable laying cost is selected as the first transmission cable laying path, and the candidate coordinates corresponding to the candidate transmission cable laying path are determined as the target coordinates, that is, the site selection location of the offshore boost platform.

[0083] Furthermore, the laying paths of the low-voltage cables and the low-voltage converging cables are planned according to the laying path of the first transmission cable, and at the same time, the shortest path to the low-voltage converging cables after avoiding obstacles is found for the remaining wind turbines. The determination of the shortest path can be based on the ACO algorithm, the A* algorithm, the random search tree algorithm, etc.

[0084] For example, Figure 3 As shown, the laying path of the first transmission cable is determined to be the transmission cable laying path between the candidate coordinate A and the wind turbine 2, and then the laying paths of the low-voltage cable and the low-voltage merging cable are planned on the transmission cable laying path. On this basis, the shortest path to the low-voltage merging cable after avoiding obstacles is found for the remaining wind turbines.

[0085] Based on the above steps S401 to S403, the transmission cable laying cost information corresponding to the candidate transmission cable laying path is obtained; the candidate transmission cable laying paths are screened based on the transmission cable laying cost information to obtain a first transmission cable laying path; the candidate coordinates corresponding to the first transmission cable laying path are determined as the target coordinates, and the site selection of the offshore booster platform and the laying path of the transmission cable are optimized by comprehensively considering the site selection of the offshore booster platform and the laying path of the transmission cable, thereby achieving the technical effect of comprehensively considering the geographical environment of the offshore wind farm and the site selection of the offshore booster platform to reduce the cable laying cost and operation and maintenance complexity of the offshore wind power cluster transmission system, thereby solving the technical problem of high transmission cable laying cost and high operation and maintenance complexity of the offshore wind power cluster transmission system due to failure to comprehensively consider the site selection of the offshore booster platform and the laying path of the transmission cable in the related technology.

[0086] Optionally, the method for determining the structure of the offshore wind power cluster transmission system further includes:

[0087] Step S291, determining a search area based on the coordinates and center coordinates of multiple wind turbines;

[0088] In step S291, the search area is determined based on the coordinates of all wind turbines in the offshore wind power cluster and the central coordinates of the onshore centralized control center, which covers the potential connection area between all wind turbines and the centralized control center.

[0089] Step S292, gridding the search area to obtain grid point data;

[0090] Specifically, the search area is divided into a series of smaller, regular grids, and the center point of each grid is called a grid point. Gridding can transform continuous spatial problems into discrete node network problems, which is convenient for calculation and optimization. The coordinate information of each grid point is recorded, that is, the grid point data, which will be used in the subsequent path search and optimization process.

[0091] Step S293, in response to determining that there are obstacles on the paths between the grid points based on the area restriction information, determining the heuristic data in the probability transfer rule as a maximum value.

[0092] Specifically, when it is determined based on the regional restriction information that there are obstacles on the path between the grid points, it means that the path is not feasible, so the heuristic data ηij in the probability transfer rule is determined to be a maximum value. For example, in an offshore wind farm in a real environment, there may be a variety of natural or artificial obstacles, such as marine life protection areas, other submarine facilities, changes in submarine terrain, etc., which may limit the laying path of cables. If the path between two grid points is affected by obstacles, then this path is considered infeasible.

[0093] Based on the above steps S291 to S293, the search area is determined based on the coordinates and center coordinates of multiple wind turbines; the search area is gridded to obtain grid point data; in response to the determination that there are obstacles in the path between the grid points based on the area restriction information, the heuristic data in the probability transfer rule is determined as a maximum value, which effectively improves the path planning efficiency, feasibility and safety of the offshore wind power cluster transmission system, and can achieve efficient and reliable transmission path optimization in a complex environment.

[0094] Optionally, in step S26, determining the second transmission cable laying path based on the center coordinates and the target coordinates includes:

[0095] Step S261, searching between the target coordinates and the center coordinates using an ant colony algorithm in combination with the area restriction information to obtain a second transmission cable laying path.

[0096] Specifically, before performing a path search, it is necessary to consider the actual regional restriction information of the offshore wind power cluster transmission system and the surrounding area. The regional restriction information includes but is not limited to: seabed topography, marine biological protection areas, and other seabed facilities (such as oil and gas pipelines, other cables). Based on the regional restriction information, it can be determined which paths are feasible and which paths are infeasible due to obstacles or restrictions. Infeasible paths will be marked in the ACO algorithm to avoid being selected by ants during the search process.

[0097] Specifically, the ACO algorithm is used to "move" between the target coordinates (the selected offshore booster platform location) and the center coordinates (the location of the onshore centralized control center) to find the path with the lowest cost. During the search process, the ants will decide the direction of movement based on the pheromone concentration and heuristic information (cost) on the path. Paths with higher pheromone concentrations are more likely to be selected. After multiple rounds of search and pheromone updates, the ACO algorithm will gradually converge to the optimal path from the target coordinates to the center coordinates, that is, the second transmission cable laying path.

[0098] Exemplarily, the best location for the offshore boost platform has been determined through the previous steps. Next, it is necessary to determine the optimal high-voltage cable path from this location to the onshore centralized control center. First, based on the seabed topography of the area and the defined obstacle area, a detailed grid map is created, with each grid point representing a small section of the seabed area. Then, the ACO algorithm lets the "ants" start from the target coordinates of the offshore boost platform and try to find a path to the onshore centralized control center. During the search process, the "ants" will choose the direction of the next move based on the pheromones on the path (representing the frequency of passing through the path in previous searches) and heuristic information (cost). If a path is marked as restricted or there are obstacles, the "ants" will avoid choosing this path. After multiple iterations and pheromone updates, the algorithm converges to an optimal path, namely the second transmission cable laying path, which will be used to guide the actual laying of high-voltage cables and achieve efficient connection from the offshore boost platform to the onshore centralized control center.

[0099] Based on the above step S261, the ant colony algorithm is used to search between the target coordinates and the center coordinates in combination with the regional restriction information to obtain the second transmission cable laying path. By optimizing the transmission path from the offshore booster platform to the onshore centralized control center, the overall efficiency of the wind farm can be significantly improved. A shorter and lower-cost transmission path can reduce energy loss and improve power transmission efficiency, thereby optimizing the operating efficiency of the entire offshore wind power cluster.

[0100] Figure 4 is a flow chart of another method for determining the structure of an offshore wind power cluster transmission system according to one embodiment of the present invention. Figure 4 As shown, the method comprises the following steps:

[0101] Step S401, obtaining coordinates of multiple wind turbines in an offshore wind power cluster, central coordinates of an onshore centralized control center, and area restriction information;

[0102] Step S402, connecting the coordinates of the multiple wind turbines with the center coordinates to form multiple test straight lines;

[0103] Step S403, dividing the plurality of test straight lines into equal distances to obtain a plurality of equal distance lines;

[0104] Step S404, determining the midpoints of the plurality of equidistant lines as candidate coordinates;

[0105] Step S405, determining the candidate coordinates as food points;

[0106] Step S406, determining the coordinates of the plurality of wind turbines as an ant nest;

[0107] Step S407, searching between the food point and the ant nest based on the probability transfer rule, the area restriction information and the objective function to obtain a candidate transmission cable laying path;

[0108] Step S408, obtaining transmission cable laying cost information corresponding to the candidate transmission cable laying path;

[0109] Step S409, screening candidate transmission cable laying paths based on the transmission cable laying cost information to obtain a first transmission cable laying path;

[0110] Step S410, determining the candidate coordinates corresponding to the first transmission cable laying path as the target coordinates;

[0111] Step S411, searching between the target coordinates and the center coordinates using an ant colony algorithm in combination with the area restriction information to obtain a second transmission cable laying path;

[0112] Step S412: determining the offshore wind power cluster transmission system structure based on the first transmission cable laying path, the second transmission cable laying path and the target coordinates.

[0113] Based on the above steps S401 to S412, the coordinates of multiple wind turbines in the offshore wind power cluster, the central coordinates of the onshore centralized control center and the regional restriction information are obtained, and based on the coordinates and the central coordinates of the multiple wind turbines, the candidate coordinates of the offshore booster platform are determined; based on the candidate coordinates and the regional restriction information, the first transmission cable laying path and the target coordinates of the offshore booster platform are determined; based on the central coordinates and the target coordinates, the second transmission cable laying path is determined; based on the first transmission cable laying path, the second transmission cable laying path and the target coordinates, the transmission system of the offshore wind power cluster is determined. The system structure achieves the purpose of optimizing the site selection of the offshore booster platform and the laying path of the transmission cable by comprehensively considering the site selection of the offshore booster platform and the laying path of the transmission cable, thereby achieving the technical effect of comprehensively considering the geographical environment of the offshore wind farm and the site selection of the offshore booster platform to reduce the cable laying cost and operation and maintenance complexity of the offshore wind power cluster transmission system, thereby solving the technical problem of high transmission cable laying cost and high operation and maintenance complexity of the offshore wind power cluster transmission system due to failure to comprehensively consider the site selection of the offshore booster platform and the laying path of the transmission cable in the related technology.
