Shi-ping XIAN, Yu-long HUANG

Abstract


This paper introduced the detail steps of Latin hypercube sampling method in mid-term voltage stability analysis considering uncertainty of load and wind generation power. Then by introduction of quasi steady trajectory sensitivity, the corresponding sampling efficient is highly improved. Finally it is demonstrated on IEEE 14 bus system that it’s feasible to use the quasi steady trajectory sensitivity to solve the problems of mid-term voltage stability associated with randomness and it’s more efficient than the time domain simulation.
