Following the first Workshop on DC technologies at RWTH, last June 23,the 2nd workshop, organized by Seoul NationalUniversity and RWTH Aachen University, took place at KEPCO, Naju, South Koreaon December 16, 2022. Presentations were given by Prof. De Doncker (on site) and online by Prof. Figgemeier and Prof. Rupp. As KEPCO was hosting theworkshop it gave the attendees an opportunity to visit the 30 MW +/- 35 kV MVDCpilot test bed (see poster picture) of the The New Energy Technology Laboratoryof KEPCO at Naju. Despite the freezing temperatures (-12 °C) Dr. Kang Sik Kimenthusiastically explained the design and the capabilities of this test bed (see picture). Clearly, with this facility, KEPCO impressively demonstrates thebenefits of MVDC distribution systems. The main goal of the pilot test facilityis to improve power quality and reduce RES connection delay issues. Furthermore, the cost reduction by utilizing 20 km MVDC cables versus AC cables will be evaluated.
