This book provides comprehensive coverage of the resilience and reliability of power grids. It begins with the definition and theory of power grid resilience and then extends to cover the full spectrum of power grid resilience, ranging from planning to operation including system hardening, mitigation, and restoration. Practical case studies on both the bulk power system and distribution networks are included to illustrate how adaptive measures can be taken to improve the grid resilience against large-scale events.  Power Grid Resilience: Theory and Applications is a state-of-the-art guide that is essential reading for practicing engineers, researchers, and scientists working in the power and energy industry. The book is also useful as a reference for undergraduate and graduate students studying power systems.
