Voltage Stability of Electric Power Systems
The book describes practical methods that can be used for voltage security assessment and offers a variety of examples. This is a first attempt to condense the technical papers and reports on this subject into a single, coherent, and theoretically sound presentation.Transmission, generation, and load aspects of the voltage instability problem are treated in detail, and a comprehensive power system model for use in voltage stability analysis is developed and explained. Notions and concepts from nonlinear system theory are presented in a tutorial manner for the use of those new to the field.
Security of Ubiquitous Computing Systems : Selected Topics
T this book arise out of the EU Cost Action project Cryptacus, the objective of which was to improve and adapt existent cryptanalysis methodologies and tools to the ubiquitous computing framework. The cryptanalysis implemented lies along four axes: cryptographic models, cryptanalysis of building blocks, hardware and software security engineering, and security assessment of real-world systems.
Data and applications security XXI ; 21st Annual IFIP WG 11.3 Working Conference on data and applications security, Redondo Beach, CA, USA, July 8-11, 2007, Proceedings
This book presented secure query evaluation, location-based security/mobile security, distributed security issues, cryptographic-based security, temporal access control and usage control, as well as system security issues.
Data and applications security XIX ; 19th Annual IFIP WG 11.3 working conference on data and applications security, Storrs, CT, USA, August 7-10, 2005, Proceedings
Constitutes the refereed proceedings of the 19th Annual Working Conference on Data and Applications Security held in Storrs, CT, USA, in August 2005. The papers present theory, technique, applications, and practical experience of data and application security with topics like cryptography, privacy, security planning and administration, and more.
Computational Techniques for Voltage Stability Assessment and Control
The key concepts of both saddle node and Hopf bifurcation are covered. These are illustrated with the differential-algebraic equation (DAE) model of the system. The model is complex enough to include Load Tap-Changing transformers as well as HVDC models. The dynamic model of the generating unit includes the exciter since it plays a crucial role in voltage stability. A promising decoupled dynamic simulation technique is introduced for time domain analysis. Computational Techniques for Voltage Stability Assessment and Control provides the computational tools and algorithms needed for development of on-line voltage security assessment
