Bus fast charging station (FCS) charging power is large, the load short-term peak power and charging costs is large. Configuring the battery energy storage system (BESS) in the FCS can reduce the load peak and the distribution capacity, and can also use the Time-of-Use (TOU) electricity prices to reduce the charging costs. But the storage capacity demand is too large if configure the BESS directly, economy is not ideal. In fact, the plug-in electric bus driving behavior is regular, it can improve the load characteristics by adjusting the bus's charging strategy, and then consider the configuration of BESS. In this paper, first, the load model of the bus FCS was established. Taking a plug-in electric bus station in Beijing as an example, the charging load of the station was simulated and analyzed using two charging strategies. Then, take maximize the net income of the bus FCS system as the objective, the economic model of the FCS with the BESS is established. The economy of the bus FCS system was simulated and analyzed without and with the BESS under two charging strategies. Finally, the results demonstrate that configure BESS in the bus FCS can improve the station system economy.
