Research on automatic optimization of offshore wind turbines regular layout considering engineering constraints
In view of the characteristics that the wind turbine layout in offshore wind farms should conform to the multi-row regular lay-out form,an automatic optimization method for wind turbine regular layout was proposed.The method adopted the regular layout automat-ic optimization algorithm with parallelogram as the basic layout unit to traverse and obtain the parallelogram layout with optimal energy production firstly.Then,on this basis,a three-step optimization process was carried out,including boundary fitting,end position move-ment,and spacing fine-tuning,to ensure row regularity while further improving the power generation of the wind farm.An actual offshore wind farm project was selected to verify the automatic optimization method for wind turbine regular layout proposed in this paper,and the algorithm optimization result was compared with the manual experience layout scheme.The results showed that the algorithm optimiza-tion layout scheme reduced the average wake loss of wind turbines by 0.31％compared to the manual experience layout scheme,and in-creased the annual grid power of wind farms by 3.84 GWh.The optimization method proposed has high computational efficiency,and the obtained wind turbine layout scheme can achieve maximum power generation of the wind farm and meet practical engineering re-quirements.
