摘要
Abstract
The dynamic coupling relations among the source,network and load in a power system together with their in-teractive influences are difficult to analyze. Especially,the coupling characteristics will become increasingly complex along with the introduction of new energy sources,new technologies,and new equipment. To obtain the reactive power compensation scheme which is in accordance with the system’s dynamic characteristics,the related definitions of dy-namic impedance matrix are given in this paper based on the comprehensive dynamic equivalence. Combined with the dynamic impedance matrix and power weights,the passive/active impedance indicators of nodes are derived with the consideration of power weights. Afterwards,the node that satisfies the stability requirement is selected as reactive pow-er compensation. Finally,the reactive power compensation scheme is obtained with the consideration of dynamic char-acteristics of power grid. Simulation results show that the proposed passive/active impedance indicators can be applied to analyze the self-stability/resulting stability of nodes,and the novel reactive power compensation scheme can effective-ly reduce the voltage fluctuations of nodes while improving the voltage stability level.关键词
