Super decentralized control for distribution voltage regulation robust against imperfect power flow data collection

Super Decentralized Control is a cooperative control method for voltage control devices on distribution networks. Each controller has a state estimation function and an optimal control function. The state estimation function estimates distribution voltage and current from imperfect power flow observations collected via limited communication lines. The optimal control function optimizes control of each voltage control device on the basis of a comparison between estimations and target voltage. By superposition of voltage controls, the distribution voltage is regulated as a decentralized feedback system. We designed a mathematical model of Super Decentralized Control and confirmed the capability of the model through power flow simulation.
