Wind Farm Optimization For Offshore Platform Power Supply

Wind farm layout optimization is an important issue to be considered in the development process of the actual wind power market.Adjusting the layout of wind farms can have a significant impact on the overall operating efficiency of wind farms.As for offshore wind farms,it is important to optimize the layout of wind farms in different periods due to the changes of offshore wind resources.So this paper presents a multi-period optimization of floating type wind turbine layout,through the wind resource distribution situation,the floating type wind turbine period is divided,and at the same time,in this paper,a genetic algorithm and Geosteiner algorithm are used to optimize the solution and optimize the layout of wind farms under different periods,which is of great significance to improve the power generation efficiency of wind farms.This paper adopted the multi-period way for open sea floating wind turbine layout,and according to offshore wind resources distribution,the number of wind farm operation period is divided into 1-6 periods,to contrast and analyze of the operation of the wind farm effect under different period.The results show that the multi-period optimization of wind farm is beneficial to increase the total annual economic benefits.In addition,the annual total economic benefits obtained when the wind farm is divided into six periods are 18% higher than that of a single period,indicating the advantages of multi-period optimization in improving the efficiency of wind farm.At the same time,this article also discussed the way of different kinds of wind turbine combination under the condition of multiple periods to simulate the operating effect.The result shows that wind turbine combination of different types is better for reducing the levelized cost of energy(LCOE).Therefore,there will be different schemes under different periods.When the number of periods is 2,the number of turbines when rated power is 3.5 MW and 12 MW is 11 and 2 can meet the minimized LCOE,which is 0.1031 €/k W·h.When the number of periods is 3,the minimized LCOE is 0.1031 €/k W·h when the number of 3.5 MW turbines is 11 can meet the open sea platform demand.To sum up,this paper completed the multi-period layout results of the floating wind farm through data collection and sorting,model building,algorithm optimization and other steps.It can provide some reference for wind farm layout optimization under multi-period condition.
