要約(日本語): This paper presents the novel reduction methods of distribution system with PVs. In the proposed methods, low-voltage distribution systems are integrated into an aggregated model as one simple unit of distribution system. The aggregated model is expressed by a parallel connection of one equivalent current source and one equivalent admittance. The proposed method enables to consider the effect of PVs penetrated in distribution system on the transient stability in the trunk power system. In order to verify the proposed method, the system reduction method is applied to a low voltage distribution system model.
