Smart railway energy management system is one of the greenest, most modern, and eco-friendly techniques which optimizes energy usage and enhances efficiency in railway stations. As REMS is based on smart grid concepts, it can integrate with various railway components, using advanced technologies to monitor and control energy consumption.
Notably, a 6.5% and 9.6% reduction in supply energy is observed with PV and ESS integration for DF and AT configurations, respectively. These results underscore the imperative of the integration to optimize energy management in railway systems, fostering efficient energy utilization, potential cost savings, and environmental sustainability.

This study explores the integration of photovoltaic (PV) systems and energy storage systems (ESS) into AC railways, focusing on their impact on energy consumption and overall system performance. A mathematical model of the railway system is developed, and two case studies are performed on a standard AC railway route servicing suburban train.
Moreover, the most efficient option is found to be the reuse of RBE by ESS, PV, and WT. This option achieves a 56.09% reduction in costs for the stochastic approach. The findings highlight the significant benefits of incorporating ESS, PV, and WT in reducing the operational costs of smart railway stations.
The structure of the proposed convex programming (CP) model is used for fast and efficient optimization of decision variables, Equipment size, and the cost function of the station for
