摘　　要：电力系统中负载分布不均匀导致缺失,且缺乏有效的负荷调节和平衡机制,容易导致线路过载问题。为此提出基于DBSCAN算法的电力系统线路过载控制策略研究。对原始电力系统中缺失的负荷数据通过DBSCAN二次聚类方法进行修补,以获得更全面的负荷数据;修补后的负荷数据用来构建线路过载控制模型。在构建模型时,以用电负荷、机组有功调整以及电压偏差最小为目标函数,以发电功率、负荷节点功率以及节点电压负荷为约束条件;使用二进制布谷鸟搜索算法对该模型进行求解,获取满足约束条件的最优解,通过不断地迭代和调整搜索的位置,寻找电力系统线路过载控制的最优策略。实验结果表明:所提方法的功率波动及电压偏移控制效果较好,在保障系统较好的线路过载控制效果的同时,具有较高的计算效率。The uneven distribution of loads in the power system and the lack of effective load regulation and balancing mechanisms can easily lead to line overload issues.Therefore,a study on the overload control strategy of power system lines based on DBSCAN algorithm is proposed.Fix the missing load data in the original power system using DBSCAN secondary clustering method to obtain more comprehensive load data;The repaired load data is used to construct a line overload control model.When constructing the model,the objective function is to minimize the electricity load,unit active power adjustment,and voltage deviation,and the constraint conditions are the generation power,load node power,and node voltage load;The binary cuckoo search algorithm is used to solve the model and obtain the optimal solution that meets the constraint conditions.By continuously iterating and adjusting the search position,the optimal strategy for line overload control in the power system is found.The experimental results show that the proposed method has good control effects on power fluctuations and voltage offsets,and has high computational efficiency while ensuring good line overload control effect in the system.
