This book discusses HVDC grids based on multi-terminal voltage-source converters (VSC), which is suitable for the connection of offshore wind farms and  a possible solution for a continent wide overlay grid. HVDC Grids: For Offshore and Supergrid of the Future begins by introducing and analyzing the motivations and energy policy drives for developing offshore grids and the European Supergrid. HVDC transmission technology and offshore equipment are described in the second part of the book. The third part of the book discusses how HVDC grids can be developed and integrated in the existing power system. The fourth part of the book focuses on HVDC grid integration, in studies, for different time domains of electric power systems. The book concludes by discussing developments of advanced control methods and control devices for enabling DC grids.

This book is intended for power system engineers and academics with an interest in HVDC or power systems, and policy makers. The book also provides a solid background for researchers working with  VSC-HVDC technologies, power electronic devices, offshore wind farm integration, and DC grid protection.

This book explores the mechanisms and applications of acoustic metasurfaces in the hypersonic transition control area. It begins with an introduction of the concepts of acoustic metasurface and hypersonic boundary-layer stabilization, which also provides a full scene of the research progress in the past two decades. This book then discusses the modeling methods of various acoustic metasurfaces, including the regular and irregular ones, and describes how the models are to be used in theoretical analysis and numerical calculations. The design strategies and optimization methods are presented to promote the applications in the engineering community. The possible stabilization mechanisms are explored, and the proposed analysis methods are used to clarify other flow instabilities. This book delivers valuable insight for aerospace engineers, postgraduate students, and researchers.
