摘要: |
开发海上风电基地具有统筹布局、统一规划的优势。小规模海上风电场送出规划方法不再适用于千万千瓦级海上风电基地,其送出系统规划包括海上风电基地分区、海上升压站及汇集站选址、输电线路及并网点优选。鉴于此,提出一种基于编码规划矩阵的海上风电基地送出系统规划方法。首先,提出改进K-means法对海上风电基地进行分区。其次,考虑到海上风电基地风电机组容量的不同及海缆线路损耗,采用改进重心法对海上汇集站和升压站进行选址。然后,以经济性最优为目标,建立基于编码规划矩阵的海上风电基地送出系统规划模型,实现海上风电基地分区、海上升压站和海上汇集站选址、海缆选型和并网点优选的协同规划。最后,通过某实际规划的海上风电基地进行仿真验证,结果表明所提方法较传统规划方法求解更迅速,规划结果更经济。 |

Abstract: |
The development of offshore wind power base (OWPB) offers advantages in coordinated layout and unified planning. However, planning methods suitable for small-scale offshore wind farms are no longer adequate for OWPB at the ten-gigawatt level. Transmission system planning for such bases involves partitioning the wind power base, locating offshore booster and aggregation stations, optimizing transmission routes, and selecting grid connection points. To address these complexities, this paper proposes a planning method for grid integration of OWPB based on a coded planning matrix. First, the improved K-means cluster method is introduced to partition the OWPB. Second, the improved gravity center method is adopted to locate the offshore collector and booster stations, considering varying cable transmission loss and capacities of wind turbines. Then, aiming for optimal economic performance, a planning model based on a coded planning matrix is established to achieve coordinated planning of partitioning, station locating and sizing, cable selection, and grid connection point optimization. Finally, simulations are conducted using a real OWPB for verification, and the results show that the proposed method achieves faster computation and more economical planning outcomes than traditional planning methods. |
