Power quality enhancement in series compensation of the transmission line may lead to a phenomenon called Sub Synchronous Resonance (SSR). SSR is a mechanical phenomenon of coincidence of the resonant frequency of the turbine shaft and that of the generator shaft units causing shaft failure in some extreme cases. Generally, the use of FACTS devices is one of the effective methods of mitigating SSR to improve the system's performance. This work utilizes PV solar farm as STATCOM to mitigate the sub-synchronous resonance (SSR). Here PV-STATCOM acts with the dual property to provide the real power support to the system and mitigate SSR in the system. The FUZZY's control technique with the PI controller is carried out to achieve this dual objective. The execution of the proposed controller is tested on MATLAB/SIMULINK software. These results in the improvement of system performance by damping the torsional oscillations. And the use of PV-STATCOM either hinders or reduces the use of FACTS devices to achieve the same objective, and the use of a fuzzy controller results in a fast response compared to the conventional PI controller.
