Hybrid Energy Storage System Taking Advantage of Electric Vehicle Batteries for Recovering Regenerative Braking Energy in Railway Station

Nowadays, nations are moving toward the electrification of the transportation section, and the widespread development of EV charging stations and their infrastructures supplied by the grid would strain the power grid and lead to overload issues in the network. To address this challenge, this paper presents a method for utilizing the braking energy of trains in railway stations to charge EVs located in strategic areas like park-and-ride regions close to railway stations improving energy efficiency and preventing grid overload. To validate the feasibility of the proposed system, a metro substation in Milan city is considered as a case study located in outskirts of the city and contains large number of parking space for vehicles. Three different scenarios are evaluated including DC fast charging station, AC low charging station and collaborative hybrid energy storage based AC charging station as EV charging station type. The results are studied for different EV population number, charging rate and the contractual power grid. Meanwhile, the possibility of proposed system in participating as V2G technology and taking advantage of the EV’s batteries to provide ancillary support to accelerating trains is investigated regarding peak shaving objective. The results indicated that the suggested interconnected system operates effectively when a significant quantity of EVs are parked at the station. However, the results revealed that the performance of the proposed system is notably influenced by other factors and a limited number of EVs during the early morning and late evening periods. Overall, this study confirms the feasibility of energy transfer between two types of transportation means in intermodal areas

Collaborative Electric Vehicle Charging Strategy with Regenerative Braking Energy of Railway Systems in Park & Ride Areas

In the last years, focusing on electric vehicles (EVs) is enhanced by nations due to the environmental reasons and the deficiency of fossil fuels. Meanwhile, supporting the required power of widespread EV charging infrastructures (EVCIs) would surcharge the power grid and cause some problems. Utilizing the inherent energy-saving method in electric railway systems (ERSs) known as regenerative braking energy (RBE) in strategic points, like parking areas close to railway stations or park-And-ride areas can help the grid to avoid overload situations and increase energy efficiency. In this paper, a new collaborative charging method is proposed to charge EVs batteries by RBE of trains and taking advantage of batteries energy to auxiliary supply the trains during acceleration mode towards peak shaving purposes. In this context, a park-And-ride area in Milan San Donato metro substation is considered as a real case study. The simulation results are provided to validate the effectiveness of the proposed method with 24 hours train traffic considering the EV population number with different global charging/discharging rates and grid connection limits
