Max-consensus protocol to determine the regulated node in distributed voltage regulation

Abstract

AbstractLiterature that deals with optimal voltage regulation in the power distribution grid often neglects the impact of communication on their control strategies or makes hard assumptions about the communication network. This paper extends a nearly optimal reactive power allocation mechanisms for distributed renewable energy sources with communication considerations and proposes a max-consensus-based communication schema to determine the regulated node in a distributed manner. The proposed consensus mechanisms is validated by co-simulation of a multi-agent system, the IEEE 906 low voltage test feeder and a simple communication simulator to evaluate the impact of message delay and communication network topology.
