Enhancing the Climate Resilience of High-Renewable Penetration Power Systems: Long-and Short-Term Strategies

the increasing penetration of renewable energy sources into modern power systems is accelerating the global energy transition but also introducing greater operational variability and uncertainty, especially under extreme weather events. This paper analyzes the necessity of enhancing resilience in high-renewable penetration power systems, identifies limitations in conventional protective measures, and proposes a dual-layer resilience framework. The framework integrates long-term planning strategies, such as infrastructure hardening, technical standard unification, and advanced technology deployment, with short-term emergency operational strategies, including pre-event prevention, real-time response, and post-event recovery. The proposed approach addresses renewable variability, compound hazards, and interdependent infrastructure vulnerabilities. Implementation guidelines, supported by recent case studies, demonstrate how coordinated strategies can improve system adaptability, recovery capability, and service continuity under extreme conditions. This work provides practical guidance for policymakers and utilities to ensure secure, sustainable power supply in the context of climate change.
