Power New Technologies, Supercapacitors and Electrical Resistance-Free Superconducting Cables
In the future, the way we consume electricity may change, as well as the equipment that draws it from power plants and through transmission lines. Technological advancements have expanded electricity transmission from alternating current (AC) to direct current (DC), and solar panels in homes are now able to generate power. With the development of auxiliary devices such as energy storage systems (ESS), we are living in an era where homes and buildings are both power plants and power consumers. KEPCO, which is in charge of transmission and distribution, is preparing for a different future by developing power technologies. Representative examples are the development of supercapacitors for frequency regulation and superconducting cables without electrical resistance. Supercapacitors Supercapacitors for frequency regulation are a complement to lithium battery-type ESSs. One of the many roles of an ESS is to keep the electrical frequency constant at 60 Hz. If the frequency is high...
