Modeling of Multi-agent Voltage Control in Distribution Electric Networks of Railways

Abstract

The introduction of adjustable reactive power compensation devices in distribution electric networks of railways opens up new opportunities for increasing their efficiency through the use of group-based voltage control methods based on the agent-based approach. Multi-agent voltage control allows obtaining new results related to the possibility of self-organizing agents - active elements of the electric network, which leads to an increase in the reliability of power supply and power quality. Modeling of considered multi-agent control systems on classical models of system dynamics is difficult because of the complex interaction of agents due to their individual utility goals, the presence of logical operations, and the event nature of the processes. State diagrams of agents were developed for modeling multi-agent voltage control using reactive power sources in distribution electric networks of railways in the Anylogic environment. The modeling of the voltage control in the test electric network when changing the mode parameters is done. The obtained modeling results show the validity of approaches to voltage stabilization using multi-agent control methods and the possibility of their practical implementation on the basis of modern equipment.
