Abstract：Power grid operation is a complex dynamic process, the intense competition of electricity market and the randomness of load may lead to the phenomenon of power blockage in some period, and cause security hidden troubles. The Unified Power Flow controller (UPFC) can control the line powers flow and stabilize the node voltage, and effectively alleviate the problem of electrical congestion. In order to adjust the power generation schedule as little as possible, in view of the shortcoming of the existing UPFC configuration method has not fully considered the uncertainty of system operating state, this article establishes a various screens UPFC configuration model based on power system generation schedule, and divides the load according to the quarterly power generation plan, takes the minimum average value of maximum load rate of each line in each scene as the objective function, and uses the genetic algorithm to solve the optimal scheme of UPFC configuration. An analysis of IEEE-39 node system is presented to verify the correctness and effectiveness of the model and algorithm.
