Analysis the impact of Energy Storage a shared Asset between DC Railway Network and Electricity Distribution Network

European distribution networks and light-railway networks have been developed as independent networks, relying on the resilience and robustness of existing power supplies. This paper reports on findings of European Union H2020 funded E-LOBSTER project which in its concept, is proposing an innovative Railway to Grid (R+G) Management system which, combined with advanced power electronics, will be able to make the best use of the available energy on both the grids by increasing their mutual synergies and increasing the whole system efficiency. In this study, a sustainable solution, as a concept, represents a new type of electric infrastructure. In ELOBSTER, electrical energy storage will play a shared asset between grid and railway. To investigate the solution, a real case study of urban metro line is chosen for simulation study. The challenges that distribution networks are facing with integration of high intake of EV charging facilities is providing an insight on the solution addressed in the paper. The results show the effectiveness of the proposed solution.
