Sažetak
Railway transport system microgrid model is observed from the point of balancing energy flows between accelerating and decelerating trains, hybrid energy storage systems and a single supply substation connected to the main power grid. In this paper, an energy flow optimization of a railway system microgrid is presented. Optimization problem is formulated as a linear program that takes into account energy storage systems with corresponding charge and discharge efficiencies, actual electricity prices and simulated daily train consumption profiles. Performance of the proposed approach is verified through one-day simulation scenario with model predictive control scheme and by considering different prediction horizon lengths.
