本論文では無効電力出力を抑制できる新しい自律分散型rn制御方式を提案し，その動作を数値計算により検証した。rn提案手法は3つの制御方式の協調的な動作によって実現さrnれており，モデル系統を用いた試算により経済性改善の効rn果を定量的に検証した。%In a future distribution network, it is difficult to maintain voltage because a large number of distributed generators are introduced to the system. The authors have proposed an autonomous decentralized voltage control method using multi-agent technology in the previous work. However, the control method does not include the function which saves the excessive decrease of power factor of distributed generators. In this paper, we propose a new control method which is improved to save the reactive power output. Generally, an autonomous decentralized control method is inferior to a centralized control method in efficiency. However, the efficiency of this proposed method is greatly improved using local information exchange about reactive power output. The proposed method is tested in 4-node simple model and 24-node complicated model. The relationship between control performance and information exchange area is also discussed.
