3Smart research team members published an article "Hierarchical Model Predictive Control for Coordinated Electric Railway Traction System Energy Management" - H. Novak, V. Lešić, M. Vašak, in IEEE Transactions on Intelligent Transportation Systems, a prestigious IEEE scientific journal. The paper is published within a Special Issue on Intelligent Rail Transportation, focussed on development and application of intelligent technologies for improvement of railway's autonomy, cooperation and integration.

The paper presents a novel railway energy management system based on hierarchical coordination of electric traction substation energy flows and on-route trains energy consumption levels. The levels are coordinated through parametric hierarchical model predictive control with the main goal of additionally increasing the energy efficiency and decreasing the operational costs of the overall system.
