The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
The PV and storage integrated fast charging station now uses flat charge and peak discharge as well as valley charge and peak discharge, which can lower the overall energy cost. For the characteristics of photovoltaic power generation at noon, the charging time of energy storage power station is 03:30 to 05:30 and 13:30 to 16:30, respectively .
Finally, the calculation method for the SC of the charging station is constructed by defining the energy relationships among EVs, centralized energy storage, PV power and the grid. This study then provides a method to determine the daytime SC in order to offer a foundation for the grid to build a dispatching strategy.
For the characteristics of photovoltaic power generation at noon, the charging time of energy storage power station is 03:30 to 05:30 and 13:30 to 16:30, respectively . This results in the variation of the charging station's energy storage capacity as stated in Equation (15) and the constraint as displayed in (16)– (20).
This demonstrates that using energy storage facilities at the charging station can effectively alleviate the grid's load during peak electricity consumption. Fig. 8. Daily electricity requirements for electric vehicles during peak hours at charging stations.
