This paper presents a centralized control algorithm for power system performance in the Korean power system using Flexible AC Transmission Systems (FACTS) devices. The algorithm is applied to the Korean power system throughout the metropolitan area in order to alleviate inherent stability problems, especially concerns with voltage stability. Generally, control strategies are divided into local and centralized control. This paper is concerned with a centralized control strategy in terms of the global system.
In this research, input data of the proposed algorithm and network data are obtained from theSCADA/EMS system. Using the full system model, the centralized controller monitors the system conditionand decides the operating point according to the control objectives that are, in turn, dependenton system conditions.
To overcome voltage collapse problems, load-shedding is currently applied in the Korean power system.In this study, the application of the coordination between FACTS and switch capacitor (SC) canrestore the solvability without load shedding or guarantee the FV margin when the margin is insufficient.Optimal Power Flow (OPF) algorithm, for which the objective function is loss minimization, isused in a stable case.
The results illustrate examples of the proposed algorithm using SCADA/EMS data of the Korean power system in 2007.
