The phenomenon of subsynchronous resonance (SSR) is important to understand the operation and stability of the power system. The system becomes vulnerable to SSR oscillations due to series compensation that is unavoidable as it enhances transmission capability. So different alleviation measure is necessary, and this paper presents a novel control with the implementation of fuzzy logic control (FLC) and active disturbance rejection control (ADRC) for the abatement of SSR using a static synchronous compensator (STATCOM). This control can compensate for reactive power as well as alleviate SSR oscillations.Both the proposed controllers have the inherent capability to overcome the limitation of proportional and integral (PI) in a non-linear framework. In the proposed control, the use of a phase-locked loop is eliminated, thus providing a faster response. Thus, the proposed algorithm highly enhances the capability of STATCOM in controlling the level of series compensation, which results in a substantial reduction of the SSR oscillations. To validate the effectiveness of the proposed algorithm, an IEEE second benchmark model is simulated.Furthermore, the dynamics of SSR are put forth through various analyses, such as, eigenvalue analysis, frequency scan, fast Fourier analysis, and timedomain analysis, which helps to better understand the problem of SSR.
