Stability and Control of Converter-Dominated Modern Power Systems

Modern power systems are undergoing a profound transition toward low-carbon energy structures driven by the rapid expansion of renewable energy resources. The increasing penetration of wind, solar, and other renewable generation is fundamentally reshaping the architecture and operational characteristics of power grids. Unlike conventional synchronous generation, most renewable energy sources are interfaced with the grid through power electronic converters, which significantly alter system dynamics and operational behavior.As the share of inverter-interfaced generation continues to grow, traditional assumptions regarding system inertia, damping characteristics, stability mechanisms, and frequency or voltage regulation are increasingly challenged. The resulting low-inertia and converter-dominated operating conditions introduce new stability risks and complex interactions across multiple temporal and spatial scales. Ensuring secure, stable, and resilient operation of modern power systems therefore requires new analytical frameworks, control strategies, and system-level coordination mechanisms.This Research Topic aims to highlight recent advances in the modeling, analysis, stability assessment, and control of converter-dominated power systems. Particular emphasis is placed on understanding emerging dynamic characteristics, stability challenges, and advanced control solutions associated with large-scale integration of converter-based renewable generation.By bringing together contributions from academia and industry, this collection seeks to advance theoretical understanding and practical solutions for future power grids characterized by high renewable penetration, low system inertia, and strong power-electronics interactions. The goal is to support the development of reliable, flexible, and resilient power systems capable of facilitating the global transition toward sustainable energy.Topics of interest include, but are not limited to:• Modeling and dynamic analysis of converter-dominated power systems;• Stability analysis of low-inertia power systems with high renewable penetration;• Grid-forming, grid-following, and hybrid converter control strategies;• Frequency regulation and inertia support in renewable-dominated power grids;• Interaction and coupling between power electronic converters and power systems;• Coordinated voltage and frequency control in converter-rich power networks;• Oscillation analysis, mitigation, and damping control in modern power systems;• Advanced control and operational strategies for large-scale renewable integration.
