► KEPCO has planned to construct a test site for renewable energy in Jeju power system. ► One kilometer length of total 8km was designed as superconducting DC cable. ► We have developed a simulation model of the 8km HVDC system using real time digital simulator. ► The simulation result shows that the HVDC line was not affected by wind power variation. Jeju island is located approximately 100km south from the mainland of Korea, and had a peak load of about 553MW in 2008. The demand increases 7.2% a year over the last 5years. Since the wind profiles of Jeju island are more favorable than mainland of Korea, many companies have shown interest in the wind power business at the Jeju island. Moreover KEPCO has a plan for renewable energy test too whose power will be delivered by HVDC system. One kilometer length of total 8km was designed as superconducting DC cable. Rest 7km will be the conventional overhead line. In this paper, the authors have developed a simulation model of the power network around 8km HVDC system using real time digital simulator (RTDS).
