Development of KEPCO equivalent systems for the KEPCO enhanced power system simulator

Abstract

For real-time power system analysis, there exists a limitation of the scale of the system to be simulated; hence, it is necessary for real-time simulation to develop reduced equivalent systems that preserve the desired properties of the original system. In this paper, a procedure for developing equivalent systems whose scale is within the hardware capacity of the Korea Electric Power Corporation (KEPCO) real-time simulator is proposed. In addition, the KEPCO equivalent systems are developed by applying the proposed procedure. The comparison between the original system and equivalent systems illustrates the capabilities of the proposed procedure.
