説明

Large amount penetration of renewable energies as distributed generators enlarges voltage fluctuation in distribution system. This fluctuation might be suppressed within allowable range by centralized voltage control. However, centralized control needs high-cost broadband communication network. This paper proposes a decentralized control method approximately minimizing voltage deviation with local measurements. In the proposed method, regulators control voltage independently with decentralized control models determined by linear regression of minimum voltage deviation control. The simulation results showed that the proposed method regulated voltage within allowable range in severe conditions with a large amount of renewable energies.
