HVDC grids and super grids have sparked so much interest these days that researchers and engineers across the globe are talking about them, studying them, supporting them, or questioning them. This book provides valuable information for researchers, industry, and policy makers. It explains why HVDC is favorable over AC technologies for power transmission; what the key technologies and challenges are for developing an HVDC grid; how an HVDC grid will be designed and operated; and how future HVDC grids will evolve. The book also devotes significant attention to nontechnical aspects such as the influence of energy policy and regulatory frameworks.This book is a result of collaboration between industry and academia. It provides theoretical insights into the design and control of MMC technology and investigates practical aspects of the project planning, design, manufacture, implementation, and commissioning of MMC-HVDC and multi-terminal HVDC transmission technologies; filling the knowledge gap between the technology specialists and VSC-HVDC project developers and key personnel involved in those projects.
