This paper provides an H∞ robust control strategy for a permanent magnet synchronous generator (PMSG)-based wind farm to realize subsynchronous resonance suppression (SSR) subject uncertain system distortions and parameter perturbation. Firstly, eighth-order state space mathematical model of PMSG-based is established, including the grid-side converter (GSC), GSC controller, phase-locked loop (P...

In recent years, subsynchronous resonance (SSR) has frequently occurred in DFIG-connected series-compensated systems. For the analysis and prevention, it is of great importance to achieve wide area monitoring incident. This paper presents a Hankel dynamic mode decomposition (DMD) method identify SSR parameters using synchrophasor data. The basic idea employ DMD technique explore subspace matric...

Integration of wind energy resources into the grid creates several challenges for power system dynamics. More specifically, Type-3 turbines are susceptible to subsynchronous control interactions (SSCIs) when they become radially connected a series-compensated transmission line. SSCIs can cause disruptions in generation and result significant damage farm (WF) components equipment. This paper pro...

In this paper, the impacts of fixed series-compensated transmission lines (TL) on classical phasor-based fault location techniques are evaluated, in order to identify typical challenges faced by such methods. To do so, several Alternative Transients Program (ATP) simulations were carried out a 500 kV/60 Hz system, which is modeled considering parameters taken from real Brazilian network. Compar...
