Scenarios of high penetration of RES involve a high penetration of non-synchronous, inverter-based generation. On the one hand, inverter response during faults es different from the response of synchronous generation. On the other hand, high penetration of RES affects the dispatch of conventional synchronous generators that are in charge today of damping low-frequency oscillations. RES generator could also contribute to the damping of low-frequency oscillations. The objective of this project is two-fold: design of protection settings by using machine learning techniques and tuning of PSS to damp low-frequency oscillations in a inverter-dominated power system.
