Real-World Subsynchronous Oscillation Events in Power Grids With High Penetrations of Inverter-Based Resources

Yunzhi Cheng et al.

Summary: This paper presents a survey of real-world subsynchronous oscillation events associated with inverter-based resources (IBR) over the past decade. The focus is on oscillations influenced by power grid characteristics, such as series compensation or low system strength. The paper provides an overview of historical events and detailed descriptions of specific events. It also discusses causation mechanisms and proposes future research directions to address global grid needs.

Differentiating between plant level and inverter level voltage control to bring about operation of 100% inverter based resource grids

Deepak Ramasubramanian

Summary: Recent research has developed grid forming inverter control architectures that behave as voltage sources. This paper demonstrates the ability of current sources to achieve stable operation in a zero inertia network using auxiliary control loops, which has not been shown in previous research. Analysis and simulations show that fast local inverter level voltage control is crucial in ensuring the stability of the power system, indicating a paradigm shift in voltage control implementation in large solar and wind farms.
