A Total Optimization Model and the Evaluation of EV Taxi Operation and Electric Power Charge and Discharge

Abstract

We propose a total optimization model of electric power networks for EV taxi services. Planning of charging and discharging of the EV batteries are optimized in conditions of not only the transportation demand but also the PV generation. This optimization problem is modeled into a mixed integer programming model, in which each EV movement in a day is expressed. The optimal solution obtained by this model can provide performance limits for the assumed system performance and will provide important information for the design policy of the system designer or relevant stakeholders. Through some numerical experiments using actual demand data, we show the potential of the target transportation services.
