Abstract

This paper shows a robust control strategy to address the inter-area oscillations in power systems using PSS’s. The approach is based on the well-known Δω strategy of Kundur, and it was modified to take into account remote signals of the whole power system. The control center computes control signals for each generator in the system weighting the different measurements of each active generator. The robustness of the approach allows to face the communications delays due to remote
measures. The strength of the proposed technique is validated through simulations over the Kundur two-areafour- machines test case power system, here it was used
the complete model for the generators. The inter-area oscillations after a three-phase fault were successfully damped; also, the latencies which add instability in closed loop were faced.
