Guest Editorial: IEEE Transactions on Power Delivery IEEE Transactions on Power Systems Joint Special Section on Hybrid AC/DC Transmission Grids

IEEE Transactions on Power Delivery IEEE Transactions on Power Systems Joint Special Section on Hybrid AC/DC Transmission Grids HVDC technology has brought many advantages to power transmission. Examples are increased flexibility in operation, expanded power transfer capability and easier interconnection of energy sources. However, HVDC links need to be built along existing AC transmission grids. It has become increasingly evident that the future power transmission systems will become interwoven networks of AC and DC subsystems, i.e., hybrid AC/DC transmission grids. In view of this major trend in the evolution of power transmission systems, the IEEE Transactions on Power Delivery and IEEE Transactions on Power Systems have decided to publish this joint special section on the subject, with the objective to promote research, innovation and exchange in the broad field of hybrid AC/DC transmission grids. In this special section, we invited submission of original research and/or review works from both power delivery and power system perspectives.
