This paper proposes a system reduction method to reduce a bulk power system. Recently, power systems have been affected by tight supply and demand, and are operating in more stringent power flow conditions. Thus, improvements to the accuracy of reduction model (interconnected system) dynamics would be useful. In this paper, we propose a method to create a reduction model and parameters suitable for preserving the dynamics in a bulk power system. The model is determined based on an evaluation function using the power spectrum density of the oscillation waveforms obtained using the original detailed model and a reduced order model. The proposed method has the advantage that it requires only limited necessary data (short circuit capacity, total demand, and reference oscillation waveform) and does not require detailed power system data about the interconnected system. We applied the proposed method to a full‐scale system and verified the accuracy of the dynamics of the system.
