To ensure the security and economy of future power system operation in the context of a high degree of renewable energy penetration, this thesis proposes a new distributed algorithm called generalized master-slave-splitting (G-MSS) theory and a new transmission-distribution coordinated energy management (TDCEM) method that is based on the G-MSS theory. The thesis studies the mathematical properties of the G-MSS theory in detail. Based on the G-MSS theory, a distributed TDCEM method - which involves distributed security analysis, distributed voltage stability analysis, distributed economic dispatch and distributed optimal power flow for an integrated transmission-distribution system - is then developed for the first time. The thesis demonstrates that the proposed TDCEM method significantly contributes to more reliable and optimal operation in power systems. The book will benefit researchers, scientists and engineers in the field of power system operation and optimization.

This book discusses the development of promising technologies for compact antennas for high data-rate communications. It discusses and analyzes the design of compact ultra-wideband (UWB) and multiple input, multiple output (MIMO) antennas, providing essential know-how for designers, practicing engineers and scientists. These wireless communication technologies enable consumers to have convenient access to a wide range of services - anytime, anywhere. And the introduction of wireless mobile access points eliminates the limitations to communication imposed by geographical location. The Internet has allowed people to access and share information much more rapidly, but in order to achieve higher data rates with the limited available resources and imposed constraints, wireless communication technology needs to be pushed beyond the physical limits of the propagation channel. This book contributes to achieving this goal.

This book focuses on the modelling methodology of microstrip interconnects, discussing various structures of single-input multiple-output (SIMO) tree interconnects for signal integrity (SI) engineering. Further, it describes lumped and distributed transmission line elements based on single-input single-output (SIMO) models of symmetric and asymmetric trees, and investigates more complicated phenomenon, such as interbranch coupling. The modelling approaches are based on the analytical methods using the Z-, Y- and T-matrices. The established method enables the S-parameters and voltage transfer function of SIMO tree to be determined. Providing illustrative results with frequency and time domain analyses for each tree interconnect structure, the book is a valuable resource for researchers, engineers, and graduate students in fields of analogue, RF/microwave, digital and mixed circuit design, SI and manufacturing engineering.
