Technical Field

[0001] This invention relates to the field of offshore wind power technology, and in particular to a method and apparatus for co-location planning of offshore wind power and marine ranching. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, offshore wind power, with its abundant resources, high power generation efficiency, and lack of land occupation, has become a strategic emerging industry prioritized by many countries. Simultaneously, to address challenges such as declining near-shore fishery resources, limited aquaculture space, and environmental degradation, marine ranching supported by modern technology is becoming an important direction for the sustainable development of marine fisheries and is gradually expanding into deeper waters. Therefore, coordinating the needs of these two industries within the same sea area, and avoiding the duplication and inefficient use of marine resources, has become a key bottleneck in promoting high-quality development of the marine economy.

[0003] In related technologies, offshore wind power and marine aquaculture mostly adopt a "separate development" model, that is, spatially demarcating independent areas for wind farm construction and aquaculture activities respectively. However, in the above schemes, large areas of unused sea space between wind turbines are not effectively utilized, resulting in a huge waste of space resources. Based on this, there is an urgent need for a co-location planning method for offshore wind power and marine ranching to improve the low space utilization rate. Summary of the Invention

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a flowchart of a co-location planning method for offshore wind power and marine ranching according to an embodiment of the present invention; Figure 2 This is a structural diagram of a co-location planning device for offshore wind power and marine ranching according to an embodiment of the present invention. Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] The following description, with reference to the accompanying drawings, describes a method and apparatus for co-location planning of offshore wind power and marine ranching according to embodiments of the present invention.

[0030] Figure 1 This is a flowchart of a method for co-location planning of offshore wind power and marine ranching according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the method includes: S1. Obtain multi-source data and preliminary design parameters of offshore wind farms for the target planned sea area, and establish a three-dimensional sea area model based on the multi-source data and preliminary design parameters.

[0032] In one embodiment of the present invention, the aforementioned multi-source data includes seabed topographic data, geological data, hydrological data, ecological data, and meteorological data. Furthermore, in one embodiment of the present invention, the aforementioned preliminary design parameters for the wind farm may include wind turbine coordinates, wind turbine foundation dimensions, submarine cable routing, and maintenance access routes.

[0033] In one embodiment of the present invention, an integrated geographic information system (GIS) platform can be used to integrate seabed topographic data, geological data, hydrological data, ecological data and meteorological data to form a high-precision three-dimensional spatial model.

[0034] In one embodiment of the present invention, after obtaining the three-dimensional spatial model through the above steps, the discrete data points can be spatially reconstructed using the B-spline interpolation algorithm to generate a three-dimensional marine model containing wind turbine coordinates, wind turbine foundation dimensions, submarine cable routes, and maintenance channels.

[0035] In one embodiment of the present invention, the aforementioned B-spline interpolation algorithm is a local interpolation method based on control points, exhibiting good smoothness and local control capabilities. In another embodiment, spatial data of the wind turbine coordinates, wind turbine foundation dimensions, submarine cable routes, and maintenance channels of the wind farm are used as discrete control point inputs. Cubic B-splines are then used for interpolation to obtain a three-dimensional marine model. Furthermore, in another embodiment, the algorithm can construct continuous curves or surfaces by defining knot vectors and control point weights, thereby achieving high-precision fitting of complex terrain and facility layouts. In three-dimensional space, this algorithm can perform surface modeling of the wind turbine foundation contours, submarine cable routes, and maintenance channel boundaries, ensuring the geometric continuity and topological integrity of the model.

[0036] S2, based on a three-dimensional sea area model, uses the wind turbine array gap adaptation method to identify the gap areas between wind turbine arrays as potential aquaculture areas.

[0037] In one embodiment of the present invention, after obtaining a three-dimensional sea area model through the above steps, the gap area between the wind turbine arrays can be identified as a potential aquaculture area based on the three-dimensional sea area model using the wind turbine array gap adaptation method.

[0038] In one embodiment of the present invention, the method for identifying gap areas between wind turbine arrays as potential aquaculture zones based on a three-dimensional sea area model and using the wind turbine array gap adaptation method may include the following steps: S21, Determine the fan array spacing based on the impeller diameter of the fan model; S22, determine the size of a single aquaculture unit located within the fan gap based on the fan array spacing.

[0039] In one embodiment of the present invention, there is a mapping relationship between the fan array spacing and the impeller diameter of the fan model. Specifically, in one embodiment of the present invention, the fan array spacing can be a preset multiple of the impeller diameter. The preset multiple can be set as needed, such as 5 times.

[0040] In one embodiment of the present invention, after determining the fan array spacing, the size of a single aquaculture unit located within the fan array gap can be determined based on the fan array spacing, and the size of the single aquaculture unit can be defined as the potential aquaculture area. In one embodiment of the present invention, the largest edge area within the fan array gap can be defined as the size of a single aquaculture unit, such as 50m × 100m.

[0041] S3, within the potential aquaculture area, delineates the core aquaculture area, safety buffer zone, and shared waterway based on preset safety distance standards.

[0042] In one embodiment of the present invention, after determining the potential aquaculture area through the above steps, a core aquaculture area, a safety buffer zone, and a shared waterway can be delineated within the potential aquaculture area based on a preset safety distance standard.

[0043] In one embodiment of the present invention, the method for delineating a core aquaculture area, a safety buffer zone, and a shared waterway within a potential aquaculture area based on a preset safety distance standard may include the following steps: S31, the drift trajectory of the ship under the action of wind, waves and current is calculated by Monte Carlo simulation, and the first safe distance between the ship and the wind power facility, as well as the first horizontal distance between the ship and the submarine cable are determined based on the formula of the maximum braking distance of the ship. In one embodiment of the present invention, the drift trajectory of the ship under the action of wind, waves and currents is calculated by Monte Carlo simulation, and the first safe distance between the ship and the wind power facility, and the first horizontal distance between the ship and the submarine cable are determined based on the formula for the maximum braking distance of the ship. The formula for the maximum braking distance of the ship is: , For ship speed, The coefficient of friction, This is the acceleration due to gravity.

[0044] Specifically, in one embodiment of the present invention, the drift trajectory of a ship under the influence of wind, waves, and currents is dynamically modeled using the Monte Carlo simulation method, thereby providing a scientific basis for setting safe distances in the co-location planning of offshore wind power and marine ranching. The simulation process is based on random sampling of ship dynamics models and environmental disturbance parameters to construct multiple sets of ship motion trajectories under different wind speeds, wave heights, and current speeds to assess the maximum displacement range under uncontrolled or abnormal drift conditions. In the simulation, the initial state of the ship (including position, speed, and heading) and environmental parameters (such as wind speed vw, wave period T, and current speed vc) are extracted from historical meteorological data and real-time monitoring data, and randomized using normal or Weibull distributions to reflect the uncertainties of the actual marine environment.

[0045] Furthermore, in one embodiment of the present invention, the maximum skidding distance of a ship under emergency braking conditions can be calculated based on the above-mentioned formula for the maximum braking distance of a ship, thereby assessing whether the ship can complete braking within a specified safe distance when it loses power or control, thereby avoiding collisions with wind turbine foundations or submarine cables.

[0046] Furthermore, in one embodiment of the present invention, after determining the maximum displacement range and the maximum sliding distance through the above steps, the first safe distance between the ship and the wind power facility, and the first horizontal distance between the ship and the submarine cable can be determined based on the maximum displacement range and the maximum sliding distance.

[0047] In one embodiment of the present invention, the above steps can be used to set safety boundaries in the planning of shared areas for offshore wind farms and marine ranches. For example, a first safety distance of 20 meters is defined around the wind turbine foundation to ensure that the ship can still brake within this range even under the most unfavorable drift conditions; at the same time, the first horizontal spacing of the submarine cables is 10 meters to prevent damage from trawling, anchoring and other operations.

[0048] S32, Calculate the maximum offset angle of the aquaculture facility under extreme working conditions based on the dynamic swaying model of the aquaculture facility; In one embodiment of the present invention, the dynamic oscillation model of the above-mentioned aquaculture facility can be: Where h is the maximum wave height, This refers to the anchorage length of the facility.

[0049] In one embodiment of the present invention, the maximum offset angle of the aquaculture facility under extreme marine conditions is calculated by using a dynamic swaying model of the aquaculture facility, thereby providing a key basis for the design of a safety buffer zone between the aquaculture area and the wind power facility.

[0050] Furthermore, in one embodiment of the present invention, the maximum wave height h can be determined based on historical wave data of the sea area; the anchorage length L can be set according to the structural form of the aquaculture facility (such as floating cages, raft aquaculture, etc.) and design specifications to ensure that it can maintain structural stability under extreme working conditions.

[0051] S33, based on the maximum offset angle, safety distance and horizontal distance, delineates the core aquaculture area, safety buffer zone and common waterway within the potential aquaculture area.

[0052] In one embodiment of the present invention, the maximum offset angle θ is determined through the above steps. max Then, it can be done using D=L×sinθ max The maximum lateral offset D of the aquaculture facility is obtained, and the maximum lateral offset D is determined as the minimum width for defining the safety buffer zone.

[0053] In one embodiment of the invention, a safety buffer zone with a minimum width (e.g., 20m) is defined around the wind power facility, and a core aquaculture zone is defined within the potential aquaculture area outside the safety buffer zone.

[0054] Furthermore, in one embodiment of the invention, a standardized sea passage is planned for joint use by aquaculture and operation and maintenance as a common waterway.

[0055] S4. The layout of the core aquaculture area is optimized using a hydrodynamic model to obtain the target core aquaculture area.

[0056] In one embodiment of the present invention, after determining the core aquaculture area through the above steps, the layout of the core aquaculture area can be optimized using a hydrodynamic model to obtain the target core aquaculture area.

[0057] Specifically, in one embodiment of the present invention, the method of optimizing the layout of the core aquaculture area using a hydrodynamic model to obtain the target core aquaculture area may include: conducting an ecological impact assessment of the core aquaculture area based on the hydrodynamic model, and adjusting the arrangement density of each aquaculture unit in the core aquaculture area to make the water exchange rate of the core aquaculture area meet the preset conditions to obtain the target core aquaculture area.

[0058] In one embodiment of the present invention, an ecological impact assessment of the core aquaculture area can be conducted based on a hydrodynamic model, thereby adjusting the arrangement density of each aquaculture unit in the core aquaculture area so that the water exchange rate of the core aquaculture area meets the preset conditions, thus obtaining the target core aquaculture area and thereby improving the water exchange rate of the aquaculture area.

[0059] Furthermore, in one embodiment of the present invention, a MIKE or DELFT-3D hydrodynamic model is used to simulate the disturbance effect of the wind turbine foundation group on the flow field surrounding the core aquaculture area, thereby assessing the water exchange capacity. The water exchange rate is... , This refers to the amount of water exchanged between the core aquaculture area boundary and the external sea area per unit time. The total water volume of the aquaculture area. In one embodiment of the present invention, the water exchange rate can be adjusted to meet the preset condition E≥30% by adjusting the arrangement density of the aquaculture units, ensuring that the aquaculture area has good self-purification ability and pollutant diffusion ability, avoiding the formation of "dead water zone", thereby determining the target core aquaculture area.

[0060] In one embodiment of the present invention, independent marine ranches or aquaculture areas lack natural or artificial barriers for protection. Their aquaculture facilities (such as net cages and rafts) are exposed to the open marine environment for extended periods, making them susceptible to damage from severe sea conditions such as typhoons, strong waves, and currents. They also face the risk of accidental collisions with out-of-control vessels (such as merchant ships and fishing boats), resulting in insufficient safety and stability and a high risk of aquaculture losses. Therefore, in one embodiment of the present invention, after determining the safety buffer zone, shared waterway, and target core aquaculture area through the above steps, the method may further include: constructing a composite protection system for wind power facilities and the target core aquaculture area. This composite protection system includes deploying physical isolation devices around the wind turbines, deploying an intelligent early warning system at the wind farm boundary, and setting up flexible fences in the target core aquaculture area to form a three-tiered protection architecture.

[0061] In one embodiment of the present invention, the physical isolation device surrounding the wind turbine for primary protection can be a collision-resistant pile or a floating breakwater structure, the arrangement of which must meet the dynamic collision risk analysis requirements of ship maneuverability and drift range. Furthermore, in another embodiment of the present invention, the installation spacing of the physical isolation devices should be controlled within 1.5 times the diameter of the wind turbine foundation to ensure a continuous protective zone is formed even under strong wind and wave conditions; and the material of the physical isolation devices can be high-density polyethylene (HDPE) or composite fiber reinforced materials, possessing good impact resistance and corrosion resistance, suitable for marine environments with water depths of 10-40 meters.

[0062] Furthermore, in one embodiment of the present invention, the intelligent early warning system deployed at the wind farm boundary for secondary protection can integrate an Automatic Identification System (AIS), radar monitoring, and VHF radio communication modules. In one embodiment of the present invention, the intelligent early warning system can monitor the dynamics of vessels entering the warning area in real time through the AIS, identify vessels without AIS signals or deviating from their course, and automatically trigger voice warnings or flashing light alerts when the vessels are less than a preset distance (e.g., 300 meters) from the wind turbine foundation.

[0063] Furthermore, in one embodiment of the present invention, the flexible fence for three-level protection in the target core aquaculture area can be made of high-elasticity polyester fiber mesh or polyethylene floating rope structure. The fence height is not less than 2 meters, and the tensile strength is not less than 500 N / m, which can effectively resist the impact of wind and waves with a wave height not exceeding 1.5 meters. The fence design must match the size and layout of the aquaculture facilities (such as net cages) to ensure structural stability under wave action, preventing the escape of aquatic organisms or damage to the facilities.

[0064] In one embodiment of the present invention, the above-mentioned three-level protection architecture can effectively improve the safety of the aquaculture area, reduce the risk of damage to the aquaculture facilities from the external environment, and enhance the collaborative protection capability between the wind farm and the aquaculture area.

[0065] In one embodiment of the present invention, wind power projects typically do not adequately consider the future energy demands of aquaculture during the planning, design, and construction phases. This leads to the need for separate submarine cables or diesel generator sets when adding aquaculture facilities, resulting in high power supply costs and the inability to directly supply clean energy. Furthermore, the wind power infrastructure does not provide design features for the convenient installation and connection of aquaculture facilities, limiting the flexible expansion and dynamic adjustment of marine ranches. Therefore, in one embodiment of the present invention, the method may further include: reserving standardized power supply interfaces in the wind power facilities and configuring them to meet the AC and DC voltage levels of the aquaculture equipment, wherein the standardized power supply interfaces use waterproof connectors with an IP68 protection rating.

[0066] In one embodiment of the present invention, the AC interface voltage level is 380V / 220V, the DC interface voltage level is 48V / 24V, and the maximum output power of a single interface is not less than 50kW, and the total power when connected in parallel does not exceed 20% of the available power of the wind farm. ,in, For the first The power of the aquaculture facilities is N, where N is the number of parallel groups.

[0067] Furthermore, in one embodiment of the present invention, the aforementioned power supply interface employs a waterproof connector with an IP68 protection rating. This rating conforms to the IEC 60529 standard, indicating that the connector can maintain good sealing performance even when continuously immersed in water (at a depth of more than 1 meter), making it suitable for marine environments with high salt spray, high humidity, and strong splashes. The connector's outer shell is made of corrosion-resistant stainless steel or aluminum alloy, and the internal insulation material is silicone rubber or EPDM, ensuring long-term electrical safety and mechanical stability.

[0068] Furthermore, in one embodiment of the present invention, the power supply interface supports both AC and DC voltage levels. The AC interface voltage is 380V / 220V, suitable for three-phase or single-phase loads, such as aerators and circulating water pumps; the DC interface voltage is 48V / 24V, suitable for low-power monitoring equipment, control systems, and auxiliary power supply modules for intelligent cages. This design is compatible with the electrical input requirements of mainstream aquaculture equipment, avoiding equipment modifications or additional configurations due to voltage mismatch.

[0069] Furthermore, in one embodiment of the present invention, the maximum output power of the aforementioned single interface is not less than 50kW, meeting the power requirements of a medium-sized aquaculture unit. Also, to ensure the safe operation of the wind farm, the total power must not exceed 20% of the available power of the wind farm; this limit is dynamically controlled through linkage between the power distribution controller and the wind farm's SCADA system.

[0070] Furthermore, in one embodiment of the present invention, the aforementioned power supply interface can be deployed on a wind turbine platform or floating foundation structure, and connected to the wind farm's main control system via a submarine cable to provide a stable and adjustable power supply for the aquaculture facilities. Based on this, the aforementioned power supply interface enables energy sharing between wind power and aquaculture, reducing the construction and operation costs of independent power supply systems, while simultaneously improving the expansion flexibility and system integration of the aquaculture area, providing reliable technical support for the comprehensive development of deep-sea areas.

[0071] This invention discloses a method for co-location planning of offshore wind power and marine ranching. The method acquires multi-source data and preliminary design parameters of the target planned sea area and establishes a three-dimensional sea area model based on these data and parameters. Using this model, a wind turbine array gap adaptation method is employed to identify gaps between wind turbine arrays as potential aquaculture zones. Within these potential zones, a core aquaculture zone, a safety buffer zone, and a shared waterway are delineated based on preset safety distance standards. A hydrodynamic model is then used to optimize the layout of the core aquaculture zone, resulting in the target core aquaculture zone. This invention can determine the target core aquaculture zone, safety buffer zone, and shared waterway, thereby improving the utilization rate of offshore space while meeting aquaculture requirements.

[0072] To achieve the above embodiments, such as Figure 2 As shown, this embodiment also provides a co-location planning device 10 for offshore wind power and marine ranching. The device includes a setup module 201, an identification module 202, a determination module 203, and an optimization module 204. Module 201 is established to acquire multi-source data of the target planned sea area and preliminary design parameters of offshore wind farms, and to establish a three-dimensional sea area model based on the multi-source data and preliminary design parameters. The identification module 202 is used to identify the gap area between wind turbine arrays as potential aquaculture areas based on a three-dimensional sea area model and using the wind turbine array gap adaptation method. The determination module 203 is used to delineate the core aquaculture area, the safety buffer zone, and the common waterway within the potential aquaculture area based on a preset safety distance standard. The optimization module 204 is used to optimize the layout of the core aquaculture area using a hydrodynamic model to obtain the target core aquaculture area.

[0073] In one embodiment of the present invention, the aforementioned multi-source data includes seabed topographic data, geological data, hydrological data, ecological data, and meteorological data; the aforementioned preliminary design parameters for the wind farm include wind turbine coordinates, wind turbine foundation dimensions, submarine cable routes, and operation and maintenance channels.

[0074] In one embodiment of the present invention, the identification module 202 is specifically used for: The spacing of the fan array is determined based on the impeller diameter of the fan model; The size of a single aquaculture unit located within the fan array gap is determined based on the fan array spacing.

[0075] In one embodiment of the present invention, the determining module 203 is specifically used for: The drift trajectory of the ship under the action of wind, waves and currents was calculated by Monte Carlo simulation, and the first safe distance between the ship and the wind power facility, as well as the first horizontal distance between the ship and the submarine cable, were determined based on the formula for the maximum braking distance of the ship. The maximum offset angle of the aquaculture facility under extreme working conditions was calculated based on the dynamic swaying model of the aquaculture facility. Based on the maximum offset angle, safety distance, and horizontal distance, a core aquaculture area, a safety buffer zone, and a shared waterway are delineated within the potential aquaculture area.

[0076] In one embodiment of the present invention, the optimization module 204 is specifically used for: An ecological impact assessment of the core aquaculture area was conducted based on a hydrodynamic model. By adjusting the arrangement density of each aquaculture unit in the core aquaculture area, the water exchange rate of the core aquaculture area was made to meet the preset conditions, thus obtaining the target core aquaculture area.

[0077] In one embodiment of the present invention, the above-described apparatus is further configured to: A composite protection system is constructed for wind power facilities and the target core aquaculture area. The composite protection system includes deploying physical isolation devices around the wind turbines, deploying an intelligent early warning system at the boundary of the wind farm, and setting up flexible fences in the target core aquaculture area to form a three-level protection architecture.

Based on the three-dimensional sea area model, a wind turbine array gap adaptation method is used to identify the gap areas between wind turbine arrays as potential aquaculture zones. Within the potential aquaculture zones, a core aquaculture zone, a safety buffer zone, and a shared waterway are delineated based on preset safety distance standards. The layout of the core aquaculture zone is optimized using a hydrodynamic model to obtain the target core aquaculture zone. The present invention can determine the target core aquaculture zone, the safety buffer zone, and the shared waterway, thereby improving the utilization rate of offshore space while meeting aquaculture requirements.
