환경비용과 전력거래요금 차이를 고려한 한-중 계통 연계선로 경제성 분석

다국어 초록 (Multilingual Abstract)

The Northeast Asia Super Grid, a large-scale power line interconnection project in Northeast Asia, is being reviewed in the second half of 2017. As a result, there is increasing interest in research on the feasibility of interconnection between countries. Prior to the interconnection business, reviewing the technical and economical analysis is an essential process. This paper is based on the review of technical feasibility in 2016 on the interconnected between Korea-China to submarine cable. There is based on the result of the technical feasibility of the shortest distance (380 km) of submarine cable among several Korea-China interconnection sites of previous studies. The Interconnection between Korea and China is configured by HVDC ±500kV submarine cable. The following three variables are considered to construct the scenario and analyze the economic feasibility : CO₂ reduction effect, power price uncertainty of both countries, economic comparison with additional power plants. For the analysis, we use the four indices NPV (Net Present Value), IRR (Internal Rate of Return), B/C ratio(Benefit-Cost ratio) and CRP(Cost Recovery Period). The economical analysis of these scenarios are shown in this study.
