Summary form only given. Following the Northeast blackout of 2003, the Wide-Area Measurement Systems (WAMS) technology using Phasor Measurement Units (PMUs) has tremendously matured for the North American grid. However, with the rapidly increasing number of deployed PMUs, the design and deployment of an efficient wide-area communication and computing infrastructure remains one of the greatest challenges to harvest the gigantic volumes of PMU data in real-time. Neither the architecture of such networks nor the impacts of their operational uncertainties such as delays and data losses on the envisioned control actions are well understood in the current state of art. This tutorial talk will address this gap, and propose a highly resilient, fault-tolerant, and reliable distributed network control system for tomorrow's power grids using cutting-edge emerging technologies such as cloud computing and software defined networks. The proposed architecture will be realized via three interactive layers. Layer 1 will consist of physics-based controllers for power oscillation damping. Layer 2 will contain delay control rules for the communication network that work in tandem with the grid controllers. Layer 3 will consist of a supervisory controller realized through embedding and reconfiguration rules in a distributed cloud environment that continuously monitors the system status, and ensures fault-tolerance, resilience, and reliability of the overall closed-loop control system.
