A Distributed Voltage Control Method Based on Local Sensitivity Information for Incremental Distribution Network

Abstract

The access of the distributed generator supply provides a supportive effect for the node voltage in the active distribution network, but at the same time also reduces the stability of the distribution network. The algorithm establishes the sensitivity matrix and analyzes the relationship between the node voltage and the reactive power output, to coordinating the output of each reactive power. Since the undervoltage and overvoltage of different nodes can be present in the network at the same time, the overvoltage and undervoltage can be adjusted, which achieve the control of the network node voltage. The simulation results show that the algorithm can realize the effective return of the node voltage and increase the stability of the distribution network voltage.
