With the rapid social and economic development in the world, railway transportation plays an increasingly important role. As more railway industry expands, reduction in energy consumption and pollutant emission in railway systems represents a crucial factor for further development and deployment of rail way transportation. The ultimate goal is to provide higher quality service with more energy-saving. Various techniques are being developed to improve train performance in this aspect, which span from modifying the hardware structure to improving control strategy. The purpose of this article is to outline the latest development and state of the art energy-saving control techniques in railway transportation systems. The overview here is focused on two partsdriving strategy and energy storage system (ESS). Some relevant research topics and useful results are reviewed, and the research trends on energy saving are discussed.

“…With the rapid development of power electronics, regenerative braking have been widely used in the railway transit network [1]. Regenerative braking energy can be absorbed by the other train in some timing, the can further reduce energy consumption and improver the energy-saving efficiency [2][3][4]. In PSCAD software environment a railway transit network model is built in [5], regenerative current value is simulated in each substation, and has deployed the supercapacitor (SC) in accordance with the capacity and the economic evaluation; In the Matlab environment urban rail traction power supply is simulated and the capacity configuration and energy saving are analyzed in [6].…”

This paper discusses the control strategy for energy management in railway transit network with wayside (substation) supercapacitor (SC) energy storage system (ESS). Firstly, the structure of the wayside energy storage system is introduced. Secondly, the model of energy storage system is built and the control strategy is described. Thirdly, in order to estimate the required energy storage system, a useful method is proposed to predict the instantaneous regenerative energy magnitude which is delivered to each substation. Finally, the ESS configuration for each substation is determined. A simplified mathematical model of the whole metro network is established and the main features of the control strategy are developed. Numerical simulations show the efficacy of suggested control strategy and the energy saving obtained for railway transit network.

In order to prevent regenerative energy failure for the metro-trains, this paper proposes a new circuit configuration of an energy storage systems. The system enables improved performance of the powering and the regenerative braking at the high speed region without regeneration failure. Suggests a novel energy management control algorithm for metro trains based on acceleration measurement and estimation. The energy management control is integrated with the motor drive control. The algorithm is based on two nested loops on voltage and current of SC. The voltage and current references are calculated on the basis of the estimation of the train inertial force and motor torque. A simplified mathematical model of the whole electrical drive has been developed, the main features of the circuit configuration and the control strategy have been presented. Numerical simulations show the efficacy of suggested configuration and the energy saving obtained for metro trains. Experimental tests made on an electromechanical simulator fully confirm theoretical results.
