This article explores the feasibility of using the regenerative energy from braking trains to charge electric buses. A case study of New York City's subway and electric bus networks is conducted to assess the advantages and challenges of using the subway system as a power source for the buses. The findings indicate that charging electric buses during off-peak periods does not disrupt regular train operation, and connecting the buses to the third rail allows for more energy to be recuperated. Additionally, including an energy storage system decreases the peak power consumption.
This article investigates the feasibility of using regenerative energy from braking trains to charge electric buses in the context of New York City's (NYC) subway and electric bus networks. A case study centered around NYC's system has been performed to evaluate the benefits and challenges pertaining to the use of the preexisting subway network as a power supply for its new all-electric buses. The analysis shows that charging electric buses via the subway system during subway off-peak periods does not hinder regular train operation. In addition, having the charging electric buses connected to the third rail allows for more regenerative braking energy (RBE) to be recuperated, decreasing the energy wasted throughout the system. It was also found that including a wayside energy storage system (WESS) reduces the overall substation peak power consumption.
