📋 Session Abstract

The global energy transition, electrification of end-use sectors, and increasing penetration of renewable and power-electronic-based resources are fundamentally reshaping power system dynamics. Modern grids exhibit complex multi-scale, multi-physics, and stochastic behaviors that challenge conventional stability paradigms. This session provides a broad forum for advancing stability theories, assessment methodologies, and control strategies across the following key areas:

  • (1) Stability of Renewable-Rich and Converter-Interfaced Systems. Including wideband oscillations, low-inertia frequency dynamics, transient overvoltage, weak-grid interactions, and Grid-Forming (GFM) / Grid-Following (GFL) control.
  • (2) Stability in AC/DC Hybrid and Bulk Power Networks. Covering multi-infeed HVDC systems, flexible AC transmission, DC grid dynamics, and interaction between power electronics and conventional synchronous machines.
  • (3) Data-Driven and AI-Enabled Stability Assessment. Real-time stability monitoring, early warning, risk identification, digital twin technologies, and physics-informed machine learning for situational awareness.
  • (4) Coordinated Control of Distributed and Storage Resources. Virtual power plants, hybrid energy storage coordination, distributed energy resource (DER) aggregation, and multi-agent control for frequency/voltage support.
  • (5) Resilience and Stability Under Extreme and Uncertain Conditions. Stability under extreme weather, cyber-physical contingencies, cascading failure analysis, and black-start/restoration strategies.

We invite contributions on analytical modeling, computational methods, real-time assessment tools, and innovative control designs that address stability challenges in any of the above domains. Studies that bridge theoretical advances with practical implementation, from component-level control to wide-area system operation, are particularly encouraged.
