Simulation of multi-agent voltage control in distribution electric networks of railways

The introduction of adjustable devices for reactive power compensation in distribution electric networks of railways reveals new opportunities to increase their efficiency through the use of group-based voltage control methods based on the agent-based approach. Multi-agent voltage management allows obtaining new results linked the possible of self-management of the agents-active elements of the electrical network, which leads to an increase in the reliability of power supply and power quality. Modeling the 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-driven nature of the processes. Agent state diagrams have been developed in the AnyLogic environment to model multi-agent voltage control using reactive power sources in distribution electrical networks of railways. The voltage control is simulated in the test network featuring the changing mode parameters. The obtained simulation results indicate the validity of the approaches to voltage stabilization with multi-agent control methods and the possibility of their practical implementation on the basis of modern equipment.
