A study of the AC link with flexible transmission distance and half wavelength properties as an option for bulk power transmission over very long distances is presented. This alternative has been studied for many years, however, the present document introduces new insight and explanations about how the use of adequate optimisation methods of tower design and tuning procedures permits that AC transmission lines with half‐wavelength properties present enhanced performance that could be comparable with high‐voltage DC transmission systems. Issues highlighted in this work are: improvement of right of way size, flexible distance, adequate voltage‐reactive power regulation and the competitive system efficiency. Competitiveness of this AC link based on half‐wavelength properties is proved when old problems are eliminated.
