摘　　要：随着电力市场运营方式改革的深入发展,各市场参与者都为获得最大经济效益而按自己经济目标运行以及输电线路运行的随机性,容易导致线路阻塞情况的发生。针对线路的阻塞情况,用交流最优潮流分析了线路阻塞情况下系统各节点电价以及支路潮流等变化,完成了在Matlab环境下对IEEE14节点系统发生线路阻塞情况下的仿真和数据分析,取得了较好的效果。With the development of the reform of power market operation,according to their own economic goals all market participants operate on their own way in order to obtain maximum economic benefits,so the line congestion will easily happen also because of the randomness of the running transmission lines.Aiming at the situation of line congestion,the changes of each nodal price and branch power flow are analyzed by AC optimal power flow under line congestion,the simulation and data analysis are completed in the Matlab environment when line congestion occurs in IEEE 14 bus system,which has achieved good results.
