With the deepening of the global energy transition, the integration of high shares of renewable energy into power grids has become an irreversible trend. In April 2025, a regional power system disturbance in Spain and Portugal highlighted the systemic challenges faced by power systems in terms of stability maintenance, resilience assurance, and emergency response under high penetration of intermittent renewable energy. This paper systematically reviews the frontier research progress on enhancing power system stability and resilience, with a focused analysis on five key technical areas: disturbance identification and feature extraction, system inertia support, resilience quantification and assessment, multi-level coordinated control, and power-communication system coupling security. From a comprehensive perspective of cross-temporal-spatial scales, multi-hazard impacts, and system coupling, this paper aims to construct a novel analytical framework for power system stability and resilience, providing theoretical foundations and technological pathways for building a low-carbon, highly reliable, and resilient modern power system.
