Northeast Asia interconnection, and power flow considering seasonal load patterns

This paper presents the effects of an increase or a decrease of a power reserve by load flow calculations 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 North-East Asia. In these connections, the types of a power transmission for interconnection consist of the 765 kV HVAC and the HVDC. In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. The power flow map is drawn from data simulated and the comparative study is done. In this future, a power flow analysis was considered to reflect the effects of seasonal power exchanges. And the plan of assumed scenarios was considered with maximum or minimum power exchanges during summer or winter in North-East Asia countries.
