Control and communication co-design framework for Voltage/Var control in distribution network

Abstract

Today's power systems are in transformation process to a smarter grid via integration of distributed generation and intelligent loads, where advanced information and communication technology provides more reliable and efficient communication links. For purpose of dealing with the increasing dynamic parts of the smart grid and its corresponding cyber systems, we propose a control and communication co-design framework for Voltage/Var control (VVC) in distribution network, which consists of a communication protocol and an adaptive dynamic programming (ADP) based algorithm. To minimize voltage deviation and communication cost, we extend control interval by integration of an event-triggered mechanism. The effectiveness of proposed algorithm is demonstrated by a simulation using Matlab+NS-3 co-simulation in a distribution network.
