A new distributed algorithm for integrated volt-VAR control in smart grids

The goal of this paper is to present a new and completely distributed scheme for voltage control using capacitor banks in advanced distribution systems. The distributed scheme makes use of intelligent agents, which possess three key characteristics, namely autonomy, local view, and decentralization. In this paper, the intelligent shunt capacity agent will serve as a means to regulate the voltage profile under different system conditions. The agent monitors local voltages through its sensor. In the case of a violation, the agent will decide autonomously to either take immediate action or communicate with other agents through peer-to-peer communication channels to work out the best switching setting. Three case studies are provided.
