There is a knowledge gap between the technology specialists, possible VSC HVDC project developers and key personnel involved in those projects. There are several books which cover the details of the power electronics, control engineering, modeling and simulation of VSC HVDC technology based on 2 level solutions but there is a need for the field engineers, project developers and those involved in the development and management of these projects (also graduate students) to understand the basics of the new MMC-based VSC HVDC technology. This book will provide an introduction regarding technical issues for VSC HVDC converter technology and issues related to the integration of the VSC HVDC links to offshore wind projects and onshore grids. As well as describing the fundamental principles, this book will also outline the differences between the available converter technologies, and show when to apply and how to integrate the MMC VSC HVDC to offshore wind farms in order to export the energy to an AC high voltage onshore grid and future MTDC systems. With this book, readers will be familiarized with VSC HVDC in offshore wind projects and future MTDC with the particularities of MMC technology, and at the same time will learn to analyze and evaluate the differences against the 2L converter technology in all application specific issues (control, stability, faults, protection, etc).This book has guidelines to support project developers in understanding the technical issues and challenges for the integration of a VSC HVDC link between an offshore wind farm and the AC grid.
