摘　　要：为提高智能电网中的切负荷控制的精准性,提出一种基于智能电网在线监测指标控制切负荷的策略,将动态分析法应用于电网极限传输功率时阻抗模指标计算,并和灵敏度算法结合,决定切负荷的点集及顺序。利用IEEE 14节点系统进行仿真实验,结果表明,通过该方法可准确计算出需要切负荷的危险节点,将危险节点切除后系统可恢复正常的运行状态,即该方法可以精准完成智能电网的切负荷控制。In order to improve the precision of load switching control in smart grid,a load switching control strategy based on on-line monitoring index of smart grid was proposed in this paper.The dynamic analysis method was applied to calculate the impedance mode index of the power system.Combined with the sensitivity algorithm,the set and order of points for load switching were determined.The simulation experiment was carried out using by IEEE 14 node system.Experiments show that the dangerous nodes that need to be switch can be accurately calculated through this method,and the system can return to normal operation after the dangerous nodes are removed,that is,the load switching control of the smart grid can be accurately completed by this method.
