Influence of Fully Rated Converter-based wind turbines on SSR

The potential of Fully Rated Converter-based wind turbines (FRC-WTs) on the mitigation of subsynchronous resonances (SSR) in the power system having series-compensated transmission line. IEEE First Benchmark Model (FBM) was featured with Aggregated FRC-WTs to perform the studies. The potential occurrence and mitigation of the SSR in steam turbine were investigated. The Linear Quadratic Regulator (LQR) was used to damp SSR oscillations occurred at steam turbines. MATLAB code was used to perform Eigenvalue analysis and digital time-domain simulations were used to test the control strategy.
