Power system interconnection scenario and analysis between Korean peninsula and Japan

In this paper, we present possible scenarios, along with the accompanying power flow analyses and flow maps, in order to provide for the interconnection of the electric power grids between South Korea and North Korea and between South Korea and Japan. The first scenario involves the interconnection of the 765 kV HVAC power transmission system between the Kyungin area in the northwest part of South Korea and Shinpo in the eastern part of North Korea. The second scenario concerns the interconnection of the HVDC power transmission system between the Busan area in the southeast part of South Korea and the Kyushu area in the northwest part of Japan. In this paper, the various scenarios providing for the interconnection of the power systems among South Korea, North Korea and Japan are presented and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E tool.
