This monograph rethinks grid control systems from first principles, placing resilience and security at the core. Written for researchers and practitioners in power systems and cybersecurity, it addresses a critical question: how can we design controls that are both efficient and inherently secure?

The answer lies in event-triggered control (ETC). Unlike traditional periodic communication, ETC uses demand-driven, aperiodic data exchanges. This simple shift delivers two powerful benefits at once. First, it reduces communication load, shrinking the cyber attack surface. Second, it creates a “moving target” defense by obscuring control traffic patterns, making it significantly harder for adversaries to detect, model, or exploit the system. You will learn how to move beyond conventional periodic control and build next-generation secure grid architectures without sacrificing operational performance. Basic knowledge of dynamic systems is helpful, but the book is accessible to motivated readers with an interest in control and security.
