要約(英語): The power grid model, which represents the state of the power grid connection and characteristics of grid components such as loads and generators, is utilized for the fault analysis of the power grid and the necessary calculation in power grid stabilization systems. From the viewpoint of increasing the calculation time due to the increasing scale of the power grid, and the viewpoint of the difficulty of the information acquisition from the outer grid, the power grid reduction, which aggregates the full detailed power grid model into the small-scale reduced grid model, becomes necessary. The reduced grid model needs to duplicate the feature of the full detailed power grid model to the utmost, and minimize the error of the necessary amount of generator shedding as to the power grid stabilization. With this background, we have developed the power grid reduction method (DE method) which can reduce the error of power oscillation waveform, and improved DE method so that the error of the necessary amount of the generator shedding can be also reduced. For evaluating general-purpose properties of DE method, the accuracy of DE method has been evaluated not only in the standard model of IEEJ, but also in the actual system grid model of TEPCO. In this paper, from the view point of recent large-scale and rapid growth of renewables, DE method was applied and evaluated under the condition of large-scale renewables deployment in the future in consideration of the renewable's rapid fluctuation.
