多个海上风电场输电组网拓扑研究
摘要：多个海上风电场组网输电与陆地系统连接,可更好地实现海上风电场与大陆电网的协调对接。而输电组网的拓扑结构是其关键点之一。针对升压站和集控中心位置不确定,且升压站多条出线的情况,以最短交流海底电缆长度为优化目标,首先运用DFS(深度优先搜索法)和最短路径法形成初始方案,然后通过基于Dijkstra(迪杰斯特拉)算法的改进遗传算法进行拓扑优化。算例证明,该算法可自动生成多风电场输电组网的经济性最优拓扑方案,能够节省时间和人力,为未来多个风电场集群组网拓扑的自动生成提供有效的优化办法,对实际工程运用具有一定的指导意义。
Abstract:The connection of transmission system with multiple offshore wind farms and the land can achieve better coordination docking between offshore wind farm and the mainland power grid. The topology of the transmission network is one of the key issues. Because the booster station has a plurality of outlets and the position of booster stations and control center are uncertain, the shortest length of AC submarine cable is taken as the optimization objective. Firstly, DFS (depth-first search) and the shortest path methods are used to form the initial scheme. Then,the topology is optimized by using improved genetic algorithm based on Dijkstra algorithm. Finally,the simulation results show that the algorithm can generate the optimal economy topology scheme for transmission network with multiple wind farms automatically, which can save time and manpower. Meanwhile, it can provide an effective optimization method for automatic generation of cluster network topologies with multiple wind farms in the future, which is significant for the practical engineering application.
