The invention provides a complex terrain wind power plant integration optimization method comprising: a first step of micro-siting optimization: with the maximization of the generating capacity of a wind power plant as the target, calculating the position coordinates of each wind turbine iteratively by using the genetic algorithm; a second step of electricity collection line optimization: calculating a scheme with the minimum total path weight by using the Dijkstra algorithm and the minimum spanning tree algorithm and determining the connecting loops between the wind turbines; a third step of maintenance road optimization: based on the connecting paths between the wind turbines obtained in the last step of electricity collection line optimization, calculating the fill and cut generated by the distance of the paths, and, by using the minimum spanning tree algorithm, calculating the scheme with the lowest cost and determining the road connection between the wind turbines. The method has the advantages of high convergence rate, stable generalization performance and high prediction accuracy. Through micro-siting optimization, the method optimizes the layout of wind turbines and can increase the generating capacity of wind power plants and reduce the economic cost; through electricity collection line optimization, the method is economical and reasonable; through maintenance road optimization, the working efficiency is increased and the cost is reduced.

Problems solved by technology

However, there are very few researches on the route selection of roads in wind farms at home and abroad at present. Enterprises usually design roads manually based on experience. The repetitive workload is large and the work efficiency is relatively low, so the optimization of roads cannot be guaranteed.
