There are various types of distributed energy resources (DERs), which are interconnected to power grids for a decarbonized society. The amount of generation and demand power fluctuates depending on weather conditions and users' lifestyles. Thus, flexible control strategies are required to coordinate for large number of DERs. However, due to concerns about data privacy or cyber security, conventional centralized control methods are not suitable because they require all information from all DERs. In this paper, we propose a decentralized control strategy that can achieve both supply/demand power control and voltage regulation in distribution power grids. In the proposed strategy, the operator of the distribution power grid provides a virtual price to each home. And each home determines its active and reactive powers according to the decentralized optimization. We evaluate the effectiveness of the proposed strategy through numerical experiments.
