Mitigation of Active Power Oscillation in Multi-VSG Grids: An Impedance-Based Perspective
Active power oscillations frequently arise in inverter-dominated power systems with multiple converters operating under Virtual Synchronous Generator control, posing risks to system stability and protection coordination. While various mitigation strategies have been proposed, many rely on prior knowledge of system parameters, offer limited damping performance, or involve complex models that lack physical interpretability, making them difficult to apply in practice. To address these challenges, …
