The objective of this book is to assist the power industry’s on-going multibillion-dollar investments to enhance resiliency of the grid, and efforts to mitigate and respond to incidents. The proposed book’s contents will focus on improving the power grid’s ability to predict, adapt and respond to all hazards and threats, which is a paradigm shift from the current design and operation of the grid. Chapters will be organized so as to facilitate quick review of distribution system fundamentals and easy-but-thorough understanding of the importance of resiliency. The later chapters present most advanced and applicable methodologies and architectures frameworks which evaluate degradation, advance proactive action, and transform system behaviour to maintain operation, despite contingencies. These chapters will elaborate frameworks that engineers and system operators can leverage to predict cyber-physical attacks, strategize response on multiple timescales, and optimize operational efficiencies and priorities for the power grid.
