Study of integrated optimization design of wind farm in complex terrain

Aiming at the present stage the micro-site selection of wind farm in complex terrain and the wind turbine layout and other close relationship, and selecting more reasonable wind turbine layout, more online power and saving more investment as the goal, analyzing briefly the main factors influencing wind farm design in complex terrain and setting up integrated optimization mathematical model for micro-site selection, power lines and road maintenance design etc.. Based on the existing 1-year wind measurement data in the wind farm area, the genetic algorithm was used to optimize the micro-site selection. On the basis of location optimization of wind turbine, the optimization algorithms such as single-source shortest path algorithm and minimum spanning tree algorithm were used to optimize electric lines and maintenance roads. The practice shows that the research results can provide important process guidance for the actual preliminary work of wind farm construction.
