Traditional site selection methods focus on wind energy resource assessment and the convenience of power transmission, but often overlook the potential impact on the ecological environment. With increasing environmental awareness and the advancement of sustainable development strategies, how to minimize adverse ecological impacts while ensuring the economic viability and power generation efficiency of wind farms has become an urgent technical problem to be solved. Summary of the Invention

[0006] Based on the obtained wind resource data and wind turbine parameters, an objective function for the comprehensive cost per kilowatt-hour and power generation is constructed.
[0007] Based on wind resource data, wind turbine parameters, and objective functions of levelized cost of electricity (LCOE) and power generation, an initial population is generated using heuristic search. A genetic algorithm is then executed in the initial population to optimize the wind turbine layout and update the population generation by generation in order to achieve the optimal levelized cost of electricity and power generation efficiency.
[0008] The individual with the highest fitness value is selected from the updated population and used as the optimal wind turbine layout scheme for the wind farm.
[0009] Based on the optimal wind turbine layout scheme and the actual ecological conditions of the wind farm, and combined with expert knowledge, an ecological protection and restoration plan for the wind farm is generated to ensure that the construction and operation of the wind farm meet the requirements of ecological protection.
[0010] In one exemplary instance, the method further includes integrating the analysis of the wind resources, the optimized objective function, the arrangement results of the genetic algorithm, and the ecological protection and restoration scheme into a visual decision-making system to support the dynamic management and adjustment of wind farm projects.

[0013] In one exemplary instance, the wind speed frequency f(v) is statistically analyzed using the Weibull distribution according to the following formula:
[0014]
[0015] Where v represents wind speed, c is the scale parameter, and k is the shape parameter.

[0021] In one exemplary instance, generating the initial population using heuristic search includes:
[0022] From all possible installation locations, select the location with the highest wind speed as the installation location for the first fan;
[0023] Wind speed correction is applied to the grid affected by the wake effect, and stops when the first preset threshold of the required total number of wind turbines is reached;
[0024] After completing the placement of some wind turbines, the remaining wind turbine locations are screened to generate an initial population containing high-quality chromosomes.
[0025] In one exemplary instance, the wake effect is calculated as follows:
[0026]
[0027] Where u represents the wind speed at the downstream fan; u0 represents the free wind speed upstream; a represents the axial induction factor; α represents the entrainment constant; x represents the distance from the downstream location to the fan; and r represents the radius of the wake effect downwind.
[0028] In one exemplary instance, the filtering of remaining wind turbine locations includes:
[0029] The remaining grids are sorted by wind speed value, and the grids that are below the first preset threshold are selected as candidate positions. The remaining wind turbine positions are randomly selected from these candidates to form a certain number of individuals containing high-quality chromosomes. The number of high-quality individuals is set as the second preset threshold of the initial population size.
[0030] In one exemplary instance, the optimization of wind turbine layout using a genetic algorithm includes:
[0031] Perform genetic algorithm operations on the generated initial population to iteratively generate a new population;
[0032] The fitness function value is calculated for each generation of individuals, and the population is updated generation by generation until the maximum number of generations is reached or the fitness change is less than the threshold. Optimization stops and a population is obtained, which contains several wind turbine layout schemes, and the fitness values are sorted from high to low.
[0033] In one exemplary instance, the value of the fitness function is the reciprocal of the value of the objective function.
[0034] In one exemplary instance, the ecological protection and restoration scheme for generating a wind farm includes:
[0035] Based on the ecological environment of the wind farm area and the optimal wind turbine layout scheme, assess the impact of wind turbine location on the local ecosystem;

[0040] The acquisition module is used to acquire the actual wind resource data of the target wind farm and determine the wind turbine parameters of the target wind farm;
[0041] The module is used to construct an objective function for the overall cost per kilowatt-hour and power generation based on the obtained wind resource data and wind turbine parameters;
[0042] The optimization module is used to generate an initial population based on wind resource data, wind turbine parameters, and objective functions of levelized cost of electricity and power generation. It uses heuristic search to generate an initial population, and executes a genetic algorithm in the initial population to optimize the wind turbine layout and update the population generation by generation to achieve the optimal levelized cost of electricity and power generation efficiency.
[0043] The determination module is used to select the individual with the highest fitness value from the updated population as the optimal wind turbine layout scheme for the wind farm.
[0044] The generation module is used to generate ecological protection and restoration plans for wind farms based on the optimal wind turbine layout and on-site ecological conditions, combined with expert knowledge, to ensure that the construction and operation of wind farms meet ecological protection requirements.

[0059] The construction and operation of wind farms can have long-term negative impacts on biodiversity and ecosystems, thereby affecting project compliance and public support. Therefore, developing new technologies and methods to more systematically consider and mitigate these impacts is crucial for the sustainable development of the industry.
[0060] To consider the impact on the ecological environment, this application integrates expert knowledge and ecological assessment data, utilizing a visualized integrated system to manage ecological restoration and protection measures, forming an intelligent ecological restoration plan. This not only provides an innovative environmental protection approach for wind farms but also demonstrates the commitment of modern wind power projects to higher environmental responsibility standards. The core of this method is the use of an improved genetic algorithm to assess and optimize long-term wind resource distribution, enhancing the optimization process of wind turbine layout. This method not only improves the energy efficiency and economy of wind farms but also significantly enhances their adaptability to the ecological environment, providing reliable support for eco-production synergy decision-making in wind farms.
[0061] Figure 1This is a flowchart illustrating the method for arranging wind turbines in a wind farm, as described in the embodiments of this application. Figure 1 As shown. It can include:
[0062] Step 100: Obtain the actual wind resource data of the target wind farm and determine the wind turbine parameters of the target wind farm.
[0063] In one exemplary instance, the wind resource data of the target wind farm may include, but is not limited to, measured wind speed data, measured wind direction data, probability distribution of wind speed, wind rose diagram, etc.
[0064] In one embodiment, wind speed and direction data can be obtained from weather stations and wind measurement towers to provide basic data for wind energy analysis and wind turbine layout.
[0065] In one embodiment, wind rose diagrams can be drawn using measured data to determine the prevailing wind direction, providing directional basis for the overall layout of wind farms and wake effect assessment.
[0066] In one embodiment, the probability distribution of wind speed can be described by the Weibull distribution or other statistical models, thereby more accurately estimating the annual average wind speed and frequency.
[0067] In one exemplary instance, step 100 may include: acquiring wind speed and direction data from meteorological stations and meteorological towers near the target wind farm and assessing its long-term wind energy resource distribution. Based on the long-term measured wind data, a wind rose diagram of the region is drawn to determine the dominant wind direction; and the wind speed frequency is statistically analyzed using the Weibull distribution. Taking the statistical analysis of wind speed frequency f(v) using the Weibull distribution to assess the long-term wind energy resource distribution as an example, as shown in formula (1):
[0068]
[0069] In formula (1), v represents wind speed, c is the scale parameter, and k is the shape parameter.
[0070] In one exemplary instance, initial parameters for the wind turbines of a target wind farm can be determined based on the obtained wind resource data, such as setting the installed capacity of the wind farm and the turbine model. This provides the necessary foundational conditions for optimizing the construction of the target model, including the turbine hub height, blade diameter, and wind power curve.
[0071] In one embodiment, the wind turbine parameters mainly refer to the physical and performance characteristics of the wind turbine equipment, which may include, but are not limited to, wind turbine hub height, wind turbine blade diameter, wind power curve representing the relationship between wind speed and wind turbine output power, and the maximum output power of the wind turbine under rated wind speed conditions, i.e., rated power.
[0072] Step 101: Based on the obtained wind resource data and wind turbine parameters, construct an objective function for the comprehensive cost per kilowatt-hour and power generation.
[0073] In one exemplary instance, step 101 establishes a wind farm levelized cost of electricity that takes into account the ecological and environmental impact in order to find the optimal layout. The objective function consists of two parts: one part is the wind farm levelized cost of electricity, and the other part is the wind farm power generation.
[0074] The objective function includes the levelized cost of electricity (LCOE) and the amount of electricity generated. The calculation of the levelized cost of electricity is shown in formula (2):
[0075]
[0076] In formula (2), C ECC Indicates total power generation; C LCC This represents the total cost, including the initial investment cost C. I Operation and maintenance costs C OM Cost of retirement upon expiration C DR and ecological and environmental costs C ES C LCC =C I +C OM +C DR +C ES .
[0077] Electricity E i The calculation is shown in formula (3):
[0078]
[0079] In formula (3), P(v) is the power at wind speed v, which is obtained from the wind power curve; f(v) represents the probability density function of wind speed, which is obtained from the Weibull distribution, etc.; y represents the ratio of the wind turbine's normal operating time to the total annual time.
[0080] Step 102: Based on wind resource data, wind turbine parameters, and objective functions of levelized cost of electricity (LCOE) and power generation, an initial population is generated using heuristic search. A genetic algorithm is then executed in the initial population to optimize the wind turbine layout and update the population generation by generation to achieve the optimal LCOE and power generation efficiency.
[0081] In one exemplary instance, generating an initial population using heuristic search may include:
[0082] From all possible installation locations, select the location with the highest wind speed as the installation location for the first fan to ensure the efficiency of the initial layout plan;
[0083] Wind speed correction is applied to the grid affected by the wake effect, and stops when the wind speed reaches the first preset threshold of the required total number of installed wind turbines, such as 30%.
[0084] After completing the placement of some wind turbines, the remaining wind turbine locations are screened to generate an initial population containing high-quality chromosomes.
[0085] In this embodiment of the application, a heuristic search method is used to add a high-quality wind turbine layout scheme (called an individual) when the genetic algorithm initializes the population, so as to converge to a high-quality solution faster and reduce the risk of getting trapped in local optima.
[0086] In one embodiment, if there are equal wind speeds, one of them is randomly selected as the installation location of the first fan.
[0087] When one wind turbine is located downwind of another, the upstream turbine generates a wake, causing a decrease in wind speed at the downstream turbine. Therefore, a wake correction is applied to the wind speed in the downwind region. The wake effect is calculated using formula (4):
[0088]
[0089] In formula (4), u represents the wind speed at the downstream fan; u0 represents the free wind speed upstream; a represents the axial induction factor, which is a coefficient related to the energy extracted by the fan from the upstream airflow, and its value is generally 0.2; α represents the entrainment constant, and its value is 0.1; x represents the distance of the downstream location from the fan; and r represents the radius of the downwind direction affected by the wake.
[0090] In one embodiment, after completing the placement of some wind turbines, for example, reaching a preset proportion of the total number of wind turbines, such as 30%, the remaining wind turbine locations are screened. Specifically, this may include: sorting the remaining grid cells by wind speed value, selecting the top 30% of grid cells as candidate locations, randomly selecting remaining wind turbine locations from these, and finally forming a certain number of individuals containing high-quality chromosomes. The number of high-quality individuals is set as a second preset threshold of 20% of the initial population size. The initial population generated in this way contains high-quality chromosomes, which helps the genetic algorithm converge to a high-quality solution more quickly and reduces the risk of getting trapped in local optima.
[0091] In one embodiment, other genetic algorithm parameters may include, for example, population size, mutation rate, maximum number of iterations, etc., and the fitness function may be set as the reciprocal of the levelized cost of electricity (LCOE).
[0092] In one exemplary instance, optimizing wind turbine layout using a genetic algorithm may include:
[0093] Genetic algorithm operations (selection, crossover, mutation) are performed on the generated initial population to iteratively generate a new population; the fitness function value is calculated for each generation of individuals, and the population is updated generation by generation until the preset maximum number of generations is reached or the fitness change is less than the threshold, at which point the optimization stops and a population is obtained, which contains several wind turbine layout schemes, with fitness values sorted from high to low.
[0094] In a genetic algorithm, each generation contains a set of schemes (i.e., a set of different wind turbine arrangements), called a population. Through multiple iterations, individuals in each generation of the population are selected through fitness, crossover, and mutation to produce new individuals. Individuals with higher fitness (i.e., wind turbine arrangements with lower levelized cost of electricity) are more likely to be retained and carried over to the next generation. The ultimate goal of the genetic algorithm is to gradually optimize the wind turbine arrangement scheme through multiple generations of iteration, and finally find the scheme with the highest fitness, that is, the wind turbine layout with the lowest levelized cost of electricity, the highest power generation efficiency, and the best ecological friendliness.
[0095] In one embodiment, in the genetic algorithm, the fitness function is defined as the reciprocal of the objective function value, as shown in formula (5):
[0096]
[0097] As shown in formula (5), individuals with higher fitness indicate lower cost per kilowatt-hour. Wind turbine arrangement schemes with lower cost per kilowatt-hour are more likely to be selected for crossover and mutation in the genetic algorithm. This helps the genetic algorithm select the optimal wind turbine arrangement scheme until the preset maximum number of iterations or fitness value is reached, at which point the genetic algorithm terminates.
[0098] In one embodiment, the optimal wind turbine layout is selected through multiple iterations based on the calculated fitness, which may include:
[0099] Based on the calculated fitness, individuals with higher fitness (i.e., wind turbine layout schemes with low cost per kilowatt-hour and high power generation efficiency) are selected from the current population to enter the next generation. The selection operation is a prerequisite for crossover and mutation; only selected individuals will participate in crossover and mutation, thereby generating the next generation population.
[0100] The arrangement of wind turbines in two individuals can be partially swapped, for example, by cross-selecting certain turbine positions. This allows the offspring to inherit part of the layout from the parent while also acquiring new characteristics. The cross-selection operation follows the selection operation and relies on the highly fit parent provided by the selection operation.
[0101] For some individuals, the positions of some wind turbines are randomly changed, such as moving one turbine from its current location to another randomly selected location. Mutation typically follows crossover and is applied with low probability to newly generated individuals. The purpose of mutation is to break possible local optima by introducing new genes to increase population diversity, giving the algorithm the opportunity to explore a wider solution space.
[0102] In step 102 of this embodiment, a heuristic search method is used to add high-quality individuals when the genetic algorithm initializes the population, which helps to converge to a high-quality solution faster and reduces the risk of getting trapped in local optima.
[0103] Step 103: Select the individual with the highest fitness value from the updated population as the optimal wind turbine layout scheme for the wind farm.
[0104] In one exemplary instance, step 103 may include:
[0105] The fitness value of each individual in the updated population obtained from the final output of the genetic algorithm is calculated. The wind turbine layout schemes with the highest fitness values are then selected. In this way, the optimal layout is obtained by judging the merits of the wind turbine layout schemes based on the individual fitness calculation results.
[0106] Step 104: Based on the optimal wind turbine layout scheme and the actual ecological conditions of the wind farm, and combined with expert knowledge, generate an ecological protection and restoration plan for the wind farm to ensure that the construction and operation of the wind farm meet the requirements of ecological protection.
[0107] In one exemplary instance, step 104 may include:
[0108] Based on the ecological environment of the wind farm area and the optimal wind turbine layout, assess the impact of the wind turbine location on the local ecosystem, including but not limited to the potential impact on vegetation, water resources, and wildlife habitats;
[0109] Based on expert knowledge, the system intelligently generates ecological protection and restoration plans adapted to the local environment. These plans include: protecting local flora and fauna and preventing habitat impact from wind turbine construction; ensuring that wind turbine construction and operation do not affect local water quality; and post-construction vegetation restoration to reduce soil erosion and protect the local landscape. Step 104 intelligently selects an ecological restoration and protection plan for the wind farm based on local ecological conditions and expert knowledge.
[0110] The method for wind turbine layout in wind farms provided in this application collects actual wind resource data and analyzes wind energy conditions, including considerations of power generation, cost per kilowatt-hour, and wake effect. Then, a heuristic search method is used for initial optimization of the turbine layout; an improved genetic algorithm is used to further refine the turbine layout to achieve optimal power generation efficiency and cost control. This application ensures that wind power projects meet ecological requirements while achieving efficient production and management, thereby promoting the sustainable development of wind power projects and balancing economic benefits and environmental responsibility.
