Abstract

To suppress inter-area oscillations and enhance small-signal stability of power systems, wide-area damping controllers (WADC) have been used by utilising wide-area signals with high observabilities to inter-area modes. However, the requirement of the wide-area signal makes communication systems involved in the control loops of the power systems and therefore, the damping performance of the conventional WADC suffers from time-delay, data dropout and cyber-attacks. This paper proposes a local signal based inter-area damping controller (LSIADC) to suppress inter-area oscillation without using wide-area signals. The LSIADC extracts a signal with high observability to the inter-area mode from the local signal by dynamic state estimation (DSE) technique and the control signal is obtained by adding a proper phase shift to the extracted signal. The simulation results show that the proposed controller can effectively suppress inter-area oscillation using the local signal only.
