要約(英語): This paper proposes a system reduction method to reduce a bulk power system. Recently, power system is affected tight demand-supply, and is operated in more severe power flow condition. So, it is desired an accuracy improvement of reduction model (interconnected system) dynamics. In this paper, we propose a method to create a reduction model and its parameters suitable for preservation of dynamics in bulk power system. The model is determined based on evaluation function using the Power Spectrum Density of oscillation waveforms obtained using original detailed model and reduced order model. The proposed method has features that it requires only a couple of necessary data (short circuit capacity, total demand, reference oscillation waveform), without the detailed power system data about the interconnected system. The proposed method is applied to the real-size system, and verifies the accuracy of the dynamics of that system.
