Electric power systems are a vital part of modern life. We are reminded of this whenever there is a significant blackout in any of the world's developed economies. Even in countries that have a minimal reliance on electricity, we see the powerful impact of supply disruptions on the quality of daily life. The development of new technologies, including new forms of electric power generation and storage and new mechanisms to regulate the flow of power, is having an enormous impact on power systems large and small.
New and more widespread applications of electric power such as vehicle propulsion and distributed and remote generation continue to expand. Society has become increasingly reliant on electric power and consequently more vulnerable to service breakdowns.
Recent events worldwide have brought with them the startling realization that civil infrastructure systems are vulnerable to assault by small organized groups with malicious intent. Whereas power systems have traditionally been designed with a focus on protecting them from routine component failures and atypical user demand, we now also confront the fact that deliberat attacks intended to cause maximum disruption are a real possibility. In response to this changing environment, new concepts and tools have emerged that address many of the issues facing power system operation today.
This book is aimed at introducing these ideas to practicing power system engineers, control system engineers interested in power systems, and graduate students in these areas. This book is intended to provide sufficient information about power system modeling and behavior, so that a control engineer without a background in power systems can think coherently about power system control.
