Energy storage power control for electric buses

Can energy storage systems improve bus charging and transit center energy management?

The widespread use of energy storage systems in electric bus transit centers presents new opportunities and challenges for bus charging and transit center energy management. A unified optimization model is proposed to jointly optimize the bus charging plan and energy storage system power profile.

Can a bus charging method optimize energy storage systems in seconds?

The numerical simulations demonstrate that the proposed method can optimize the bus charging time, charging power, and power profile of energy storage systems in seconds. Monte Carlo simulations reveal that the proposed method significantly reduces the cost and has sufficient robustness to uncertain fluctuations in photovoltaics and office loads.

Do electric buses need a range extender?

In comparison, the absence of a range extender contributes to a 7 % reduction in energy consumption. However, considering the range anxiety of the driver, the designed electric bus for rapid transit is recommended to utilize both the range extender and parallel regenerative braking strategy.

Can a commercial solver optimize bus charging time and power profile?

This means that we can obtain the exact solution of the model quickly with a commercial solver that is fully adapted to the time scale of day-ahead scheduling. The numerical simulations demonstrate that the proposed method can optimize the bus charging time, charging power, and power profile of energy storage systems in seconds.

Should electric buses be used for rapid transit?

However, considering the range anxiety of the driver, the designed electric bus for rapid transit is recommended to utilize both the range extender and parallel regenerative braking strategy. The developed model in this work can be implemented to redesign or further optimize specific components and operating procedures of the bus.
