ABSTRACT
The fast-charging station for electric vehicles has the characteristics of a high charging power and short charging time. However, there are also problems such as severe load fluctuation and a low load rate of the transformer. This chapter explains a mathematical model for the daily total cost of the fast-charging station with an energy storage system, and a linear programming method is used to solve the problem. It analyzes the charging and discharging rates of the storage battery. The chapter aims to minimizing the total cost per day of the system, and considers the power and capacity constraints of the energy storage battery. The energy storage system can also make use of the Time-of-Use electricity price by charging during the valley-price period and discharging during the peak-price period to reduce the operation cost of the charging station.
