This book focuses on the role of systems and control. Focusing on the current and future development of smart grids in the generation and transmission of energy, it provides an overview of the smart grid control landscape, and the potential impact of the various investigations presented has for technical aspects of power generation and distribution as well as for human and economic concerns such as pricing, consumption and demand management. A tutorial exposition is provided in each chapter, describing the opportunities and challenges that lie ahead. Topics in these chapters include:
- wide-area control; - issues of estimation and integration at the transmission; - distribution, consumers, and demand management; and - cyber-physical security for smart grid control systems.
As the world grows more interconnected, we are becoming surrounded by complex networked systems. These systems consist of numerous components interlinked in complicated webs. As a result of the number of components and their intricate interconnections, complex networked systems are extremely difficult to design, analyze, control, and protect. Despite these challenges, understanding complex networked systems is becoming critical.
While wide-area controls are typically implemented within SCADA, an isolated industrial control system (ICS) with dedicated communication network, a more open and network-enabled control architecture of cyber-physical-human system will become prominent due to the proliferation of PMUs, micro-PMUs, AMI and other IoT/networking technologies, to the expansion of electricity market from the bulk transmission network to distribution networks, and to distributed controls and optimization. The ever-increasing uses of information technology and communication technology make the grid vulnerable to cyber intrusions, false data attacks, and coordinated control/measurement attacks. Various scenarios such as inside attack, denial-of-service attack, switch/breaker attack, interdiction attack, data alteration, and spoofing attack have to be investigated. For each of these potential attacks, defense mechanisms such as enhanced passive/active state estimation algorithms against data attacks should be developed. A systematic design with a layered approach is needed to address monitoring and optimization/control functions at the levels of physical layer, control layer, communication layer, network layer supervisory layer, and market layer. And finally, resilient architectures such as competitive control need to be developed to ensure the overall system dynamic stability in the presence of potential attacks, especially during the period when multilevel monitoring is active and attacks are present but yet to be identified. As attack strategies evolve with more sophistication, defense mechanisms have to be more advanced. All of these challenges fall under the fourth category of cyber-physical security and control.
The contributors describe the problems involved with each topic, and what impact these problems would have if not solved. The tutorial components and the opportunities and challenges detailed make this book ideal for anyone interested in new paradigms for modernized, smart power grids, and anyone in a field where control is applied. More specifically, it is a valuable resource for students studying smart grid control, and for researchers and academics wishing to extend their knowledge of the topic.
