Abstract

Unified power flow controller (UPFC) is a powerful FACTS device. After analyzing the disadvantages of indexes used to evaluate the impact of UPFC on power system security at present, this paper proposes a new index system with considering the mechanism of UPFC working in power system. Then the reliability model of UPFC based on real-time operating conditions is established, and the probabilistic assessment method based on Monte-Carlo simulation is developed with this model. Simulation results of IEEE 57-bus system indicate than the proposed index system and method are valid and better than traditional indexes.
