Optimization of offshore wind farm collection systems based on scanning method

The topology optimization of offshore wind farm collection systems is of great significance to reduce the investment cost of the wind farm. A feasible optimization method is proposed for the topology optimization of collection systems in the offshore wind farm, which makes the internal submarine cable connection shortest under the premise of meeting the construction requirements. Firstly, the maximum number of wind turbines allowed to be connected to submarine cables and non-crossing in the collection system are analyzed. It is proposed to use the scanning method and the minimum spanning tree to set the wind turbines connected by a single transmission submarine cable. On this basis, the adjacent positions mutation is used to improve the proposed algorithm. The results show that compared with the current project planning scheme, this method can generate multiple topologies that meet the conditions in a short time and effectively improve the economy of the system.
