“…A damping controller may be an auxiliary controller that is present in addition to another controller (like a voltage regulator in a STATCOM or SVC). Some FACTS installations have also been conceived primarily for power swing damping improvement [3]. In such cases, the damping controller function utilizes the whole control range (including transient over-rating capability, if available).…”

Modal controllability, observability, and transfer function zeros play an important role in the selection of candidate locations and feedback signals for flexible ac transmission systems (FACTS)-based power swing damping controllers. This paper investigates location of zeros of the transfer function corresponding to FACTS devices and certain local feedback signals. Signals synthesized from locally measured signals are derived that can give good pole-zero separation. It is also shown that relative modal controllability of FACTS controllers at various locations can be directly inferred from relative modal observability in certain signals at those locations. These signals are identified for various FACTS devices. Case studies using detailed model are used to validate the results.Index Terms-Flexible ac transmission systems (FACTS), power system control, power system dynamic stability.

“…It is to be noted that the estimated value of the equivalent impedance should be close enough to the actual one in order to get satisfactory response of power swing damping control. Thevenin's voltage at the SVC bus has been used as a control input signal to the PSDC loop of the SVC installed on the 500 kV transmission line between Arizona and California [9]. The Thevenin's voltage is synthesized using local measurements and the estimated value of the Thevenin's equivalent impedance seen from the SVC bus.…”

This paper presents a novel concept of Static Var Compensator (SVC) damping control using a weighted sum of bus voltage angles of remote generators that are responsible for causing interarea oscillations in power systems. These remote bus voltage angle signals are acquired through Phasor Measurement Units (PMUs). A time domain simulation study on a 39-bus New England multi-machine system is utilized to show that an SVC auxiliary damping control, based on the derivative of these remote bus voltage angles, is superior to the conventionally employed local signals in damping inter-area oscillations. The effect of transmission delay in the acquisition of remote signals is also presented and a simple mechanism to compensate this delay is proposed and validated. The robustness of the delay compensator is finally shown for a wide range of signal transmission delays. The designed SVC controller shows a superior performance in damping the inter-area oscillations despite the signal transmission delays.

The analysis of low-frequency inter-area oscillations is of special concern in large weakly interconnected power systems. The ability ofstatic VAr compensators (SVC) to contribute to damping depends strongly on the relative location ofgeneration, load and the SVc. A comprehensive investigation ofthe use ofstatic VAr compensators to aid damping oflow-frequency inter-area oscillations in a real weakly interconnected large power system is presented. Based on modal analysis, efficient algorithms to compute voltage-and power-oscillation flow for each mode of concern are developed. Controllability and observability measures are also used to assess the impact ofdynamic voltage support on system damping as well as to identify optimal locationsfor SVc. The knowledge gained by these techniques allows to investigate the influence ofexistent SVC on overall system damping as well as to evaluate suitable alternatives to site new devices. Detailed time-domain simulations are finally performed to check the validity of the knowledge gained and to assess the impact of dynamic voltage support Oil system transient behaviour. (I a)
