S UPERCONDUCTING cables have been developed to be applied to power systems due to their continuous technological innovation potential and price reduction. Several demonstration projects have been conducted worldwide to promote the availability of superconducting cables [1]–[3]. Korea also began research on the development of superconducting cables through the support of a national research fund beginning in the early 2000s. As a result, the development and verification tests of superconducting cables for AC and DC from 23 kV to 154 kV have been successful [4]–[6]. Furthermore, KEPCO, Korea’s the only electric utility company, has initiated its first commercial project,

N2 - Research on the development of a superconducting power cable for commercialization is currently underway across the world. Many demonstrations of superconducting power cables connected to real power grids have already been conducted with various designs depending on the voltage levels of the distribution and transmission lines. In Korea, the first commercial project for high temperature superconducting (HTS) power cables, 'Shingal Project' which is fully funded by Korea Electric Power Corporation (KEPCO), is underway to connect two substations with a 23 kV HTS cable with a distance of 1 km. In addition, the KEPCO Research Center (KEPRI) initiated the project in 2017 to develop the 23-kV tri-axial HTS power cables, including a cooling system, for a distance of 3 km. In this paper, the recent progress and research activities related to the two 23-kV superconducting power cables projects are discussed. An economic evaluation of the HTS power cables for commercialization in consideration of their construction environments and social issues is also presented.
