| At present,offshore wind energy technology has become the focus of global renewable energy development,and how to improve the economic benefits of wind farms in the process of wind farm development and construction has attracted much attention,especially in the process of wind farm planning wind turbine location and cable line topology.The location and layout of wind turbines is related to the power generation efficiency of all wind turbines in a wind farm,while the line topology undertakes the important task of collecting wind power generated by wind turbines and conveying it to the land power grid.The two affect and restrict each other,so it is urgent to solve the problem of how to comprehensively consider the relationship between the two to reduce the construction cost of wind farms.Wind turbine are introduced in this location and the main equipment in the process of cable line topology,each device is studied,the topological relationship between quantitative analysis and the influencing wind turbine sites and cable line topology economy the main influencing factors of cost,analyzes the blower wind turbine siteselection for wind power generation efficiency and the distance between cable topological relationship between the cost.Considering the relationship between wind turbine location layout and cable line topology optimization,a two-layer collaborative optimization method for wind turbine location layout and cable line topology optimization was proposed.Taking the total output power of offshore wind field as the target,the site selection and layout of offshore wind turbine was optimized by adopting improved genetic algorithm and considering the superposition effect of wake.Taking a classical offshore wind farm as an example,it is verified that the mathematical model and collaborative algorithm established in this thesis are of great value in improving the economic benefits of wind field.The example results show that the collaborative optimization method of wind turbine location and cable line topology takes into account the total power generation efficiency of wind farm and the investment cost of cable line topology.It has important guiding significance for the wind turbine location layout and cable line topology in the process of offshore wind field planning. |
