Possible interconnection scenarios and impacts on composite system reliability between "ROK-DPRK-RF"

Abstract

This paper presents possible interconnection scenarios and reliability analysis results on power exchange between "ROK- DPRK-RF". Four possible scenarios on power system interconnection between "ROK-DPRK-RF" are proposed to compare pre-feasibility study results in technical, economic and marketable viewpoints. Among these topics, this paper deals with the composite system reliability on interconnected power system. NEAREL(NEAREST-RELIABILITY) program, HLII level composite system reliability program, is developed to analyze the reliability index such as LOLP and EENS for this interconnected system. This paper specifies four possible interconnection scenarios and presents the study results for composite system reliability variations based on these scenarios on NEAREST(North East Asian Region Electrical System Ties) between "ROK-DPRK-RF".
