“…Even if the PV system is affected by the SSO, the AC system's strength can deteriorate. So, modified IEEE first-benchmark time-domain simulations [29] are used to study subsynchronous torsional interactions in a PV system. Here, the PV generator is connected to the same bus as the synchronous generator.…”

Series compensation is a cost-efficient way to enhance the system reliability and the power transfer capabilities of long transmission lines. As a result of series compensation, the sub-synchronous oscillation (SSO) causes a severe risk of torsional interactions (TI). Therefore, SSO becomes a serious risk factor in grid-integrated renewable energy systems. Numerous researchers have evaluated SSO instances in several types of asynchronous generators in power systems. In this paper, the categorization and the overview of the SSO phenomena have been vital for the different mechanisms, sophisticated systems, analytical techniques, and multiple reviews that have been propagated. This study provides SSO analysis for various types of renewable energy power plants. Finally, while dealing with conventional and new power systems, this study summarizes recent SSO-damping and alleviation techniques for practical perception and future perspectives.

“…In [36,37], SSRs originating from the interaction of series compensated transmission lines with synchronous generators torsional modes are studied, where auxiliary controllers are proposed to be incorporated into the PV-plant control system to enhance the damping of this type of SSR. The addition of a sub-synchronous damping controller (SSDC) to the PV plant is proposed in [38] to decrease the SSR risk in a series-compensated system.…”

This paper investigates the dynamic interactions between large-scale PV plants and nearby synchronous generators. To this end, a comprehensive model of a PV plant, including the PV arrays characteristic and their voltage controller, DC/DC converter, DC-link dynamic, DC/AC inverter controllers, and output filter, is obtained. Then, the eigenvalues of the PV plant model are calculated, and it is revealed that the PV plant has a dynamic mode in the sub-synchronous oscillations (SSOs) range. Furthermore, the modal analysis method is employed, and it is shown that the inductance of the DC/DC converter and the DC-link capacitor significantly contribute to the PV sub-synchronous mode. Also, it is shown that this mode oscillations penetrate the grid and increase the risk of sub-synchronous resonance (SSR). Then, the mechanism of dynamic interactions between large-scale PV plants and torsional modes of nearby synchronous generators is revealed. This paper also investigates the required conditions for these interactions and shows that solar irradiation level and the DC-link capacitance are the essential factors that can intensify these interactions.
