The Research on Under-Voltage Load Shedding Based on Voltage-reactive Power Sensitivity in Power System

摘要：

This paper puts forward an approach that applies active margin,sensitivity index,and N-1,N-2-voltage scanning of the network to search the voltage weak areas,based on the mechanism analysis of the voltage instability and collapse. The installation locations of under-voltage load shedding devices are determined through the voltage weak areas. On this basis,a setting method based on voltage-reactive power sensitivity is put forward. The simulation results verify the validity and practicality of the method,using the actual data of some one province network of China.
