Power Grid Resilience, Second Edition, Volume 1: Engineering for Natural Hazards delivers an updated comprehensive engineering guide to strengthening electrical infrastructure against natural disasters and emerging risks. It addresses today's urgent challenges by combining foundational theory with practical applications, giving power industry professionals a clear roadmap to bolster grid reliability under adverse conditions. Volume 1 provides an in-depth examination of how climate-driven hazards - from heat waves and droughts to fierce windstorms and blizzards - alter the performance and durability of generation, transmission, and distribution assets. Validated numerical models and documented case studies quantify vulnerabilities in equipment thermal limits, structural loads, and system stability. Dive deep into mitigation strategies that provide engineering solutions to harden and modernize the grid. Ranging from infrastructure hardening and advanced component design to adaptive operational practices and microgrid deployment, each approach is designed to ensure practitioners reduce outage risks. State-of-the-art analytics, including AI and machine learning techniques for predictive forecasting and anomaly detection, are integrated throughout as innovative tools to enhance situational awareness and crisis response. This authoritative resource empowers electrical engineers, utility planners, energy infrastructure operators, researchers, and technical policymakers to reinforce critical power systems and ensure continuity of essential services amid an evolving threat landscape.
