- •
We design a supplementary controller for a Static VAr Compensator (SVC) for inter-area oscillation damping using Synchrophasors.
- •
The design is based on a reduced-order dynamic equivalent model of the WECC network, and is simple to implement.
- •
The controller input is chosen via statistical variance analysis, and its parameters are tuned to improve the damping factors of the slow oscillation modes.
- •
The model is implemented in a real-time digital simulator, and validated using a wide range of disturbance scenarios.
- •
Detailed experimental analyses of the capacity of the SVC to satisfy the damping specifications are also presented via multiple contingencies.
