WAMS-Based Model-Free Wide-Area Damping Control by Voltage Source Converters

In this paper, a novel model-free wide-area damping control (WADC) method is proposed, which can achieve full decoupling of modes and damp multiple critical inter-area oscillations simultaneously using grid-connected voltage source converters (VSCs). The proposed purely measurement based requires no knowledge the network topology dynamic model parameters. Hence, designed controller VSCs update signals online as system operating condition varies. Numerical studies in modified IEEE 68-bus with show that estimate accurately effectively under different working conditions topologies.
