Development of equivalent systems for a KEPCO enhanced power system simulator

For real-time power system analysis, there exists a limitation to the scale of the system to be simulated, hence it is necessary for the real-time simulation to develop reduced equivalent systems which preserve the desired property of the original system. In this paper, a procedure for developing an equivalent system whose scale is reduced within the hardware capacity of a real-time simulator is proposed. Also, the proposed procedure is applied to a Korea Electric Power Corporation (KEPCO)'s system. The comparison between the original system and equivalent systems illustrates the capabilities of the proposed procedure.
