Load Topology Structure of Wind Farm Dissipation Line based on Simulated Annealing Algorithm

基于当前线路负载率具有较高的突发性、较高的实时性等特点,将对线路资源利用率和电流控制问题所采用的模拟退火算法进行风电场拓扑结构模型优化。利用模拟退火算法对线路负载均衡问题进行搜索,随后在全局最优区域附近进行局部拓扑结构优化,就可以找到线路负载均衡问题最优解。仿真研究表明,此方法不但完善了局部搜索速度,还提高了线路消纳的利用率,明显改善了线路拓扑负载不均衡的情形,进而可以为大型风电场建设中的功率设备线路拓扑优化提供有效的参考。

Based on characteristics of the current line load rate,such as high abruptness and high real-time performance,the simulated annealing algorithm employed in line resource utilization and current control issues will be used to optimize the wind farm topology structure model.By using the simulated annealing algorithm to search the line load balancing problem,and then performing local topology optimization near the global optimal area,the optimal solution of the line load balancing problem can be found.Simulation results indicate that this method can improve not only the local search speed,but also the utilization rate of line consumption,and significantly betters the situation of unbalanced load on the line topology,which can provide an effective reference for power equipment line topology optimization in large-scale wind farm construction.
