Northeast Asia interconnection, and technical & market considerations

This paper proposes technical and market considerations for the power system interconnection in Northeast Asia (NEA). In technical sides, the effects of an increase or a decrease of a power can compensate reserve power by the utilization under seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of the South Korea in NEA. The transmission voltage for interconnection between South Korea and North Korea may be used 345 kV or 765 kV HVAC, and also the transmission voltage between North Korea and North China or Far-East Russia may be used 500 kV HVAC or HVDC. In market sides, we firstly deal with a monopoly electric power market, and secondly a competitive electric power market with complexity because the transition from the regulated monopoly to a free electricity market in NEA countries radically changes the situation with ISET substantiation and financing. In this paper, in the various cases of the power system interconnections in Far-East Asia, technical and market considerations are presented.
