Multi-Terminal Direct-Current Grids
by Nilanjan Chaudhuri, Balarko Chaudhuri, Rajat Majumder, and Amirnaser Yazdani
Published 1 January 2014
A generic DC grid model that is compatible with the standard AC system stability model is presented and used to analyse the interaction between the DC grid and the host AC systems. A multi-terminal DC (MTDC) grid interconnecting multiple AC systems and offshore energy sources (e.g. wind farms) across the nations and continents would allow effective sharing of intermittent renewable resources and open market operation for secure and cost-effective supply of electricity. However, such DC grids are unprecedented with no operational experience. Despite lots of discussions and specific visions for setting up such MTDC grids particularly in Europe, none has yet been realized in practice due to two major technical barriers: * Lack of proper understanding about the interaction between a MTDC grid and the surrounding AC systems. * Commercial unavailability of efficient DC side fault current interruption technology for conventional voltage sourced converter systems This book addresses the first issue in details by presenting a comprehensive modeling, analysis and control design framework.
Possible methodologies for autonomous power sharing and exchange of frequency support across a MTDC grid and their impact on overall stability is covered. An overview of the state-of-the-art, challenges and on-going research and development initiatives for DC side fault current interruption is also presented.

Voltage–Sourced Converters in Power Systems
by Amirnaser Yazdani and Reza Iravani
Published 1 January 2010
Presents Fundamentals of Modeling, Analysis, and Control ofElectric Power Converters for Power System Applications Electronic (static) power conversion has gained widespreadacceptance in power systems applications; electronic powerconverters are increasingly employed for power conversion andconditioning, compensation, and active filtering. This bookpresents the fundamentals for analysis and control of a specificclass of high-power electronic converters the three-phasevoltage-sourced converter (VSC). Voltage-Sourced Converters inPower Systems provides a necessary and unprecedented link betweenthe principles of operation and the applications of voltage-sourcedconverters.
The book: * Describes various functions that the VSC can perform inelectric power systems * Covers a wide range of applications of the VSC in electricpower systems including wind power conversion systems * Adopts a systematic approach to the modeling and control designproblems * Illustrates the control design procedures and expectedperformance based on a comprehensive set of examples and digitalcomputer time-domain simulation studies This comprehensive text presents effective techniques formathematical modeling and control design, and helps readersunderstand the procedures and analysis steps. Detailed simulationcase studies are included to highlight the salient points andverify the designs. Voltage-Sourced Converters in Power Systems is an idealreference for senior undergraduate and graduate students in powerengineering programs, practicing engineers who deal with gridintegration and operation of distributed energy resource units,design engineers, and researchers in the area of electric powergeneration, transmission, distribution, and utilization.
