Modeling of SVC and TCSC for power system dynamic simulation

From the viewpoint of operational planning, this paper focuses on the evaluation of the impact of FACTS devices on control of voltage profile and line flows. This paper presents modeling and interfacing techniques of static VAr compensator (SVC) and thyristor controlled series capacitor (TCSC) for real time long term simulation. The proposed models are shown to be effective both for maintaining the voltage at load bus and real power flow through a typically selected line. The effectiveness of the controls are demonstrated for a standard nine bus system
