The rated power of the AC charging pile in the residential area is 7 kW; the power of the AC charging pile in the commercial area is 7 kW; the power of the DC charging pile in the commercial area is 120 kW; and the DC charging pile in the centralized charging station is rated at 120 kW.
There are 5000 charging piles in the area, the charging rate of electric vehicles is considered, according to 0.45. The S13 type transformer is selected, with a rated capacity of 1000 kVA. 6.2. Analysis of Results
In addition, the impact of EV charging on the grid can be effectively alleviated by the configuration of energy storage systems, so the configuration of energy storage in FCSs has become a future development trend.
As shown in Fig. 8, the total number of EV charging demands in the planning area in a day under the FPSM is 2989, and the charging demands of private cars reach the peak value of 117 vehicles and the sub-peak value of 102 vehicles at 13:00 and 15:00, respectively, and the distribution is relatively even at the rest of the time.
The 30-day forecasted charging demand is clustered and integrated, and based on the analysis of the charging demand characteristics of EVs in the FPSM, the corresponding optimal number of FCSs, location selection and optimal configuration of the chargers in the station are generated.
Here, is the equivalent series resistance that contributes to the energy loss at the time of charging and discharging, is the equivalent parallel resistance, which represents the energy loss of the supercapacitor due to self-discharge, L is an inductance, which is very small and is a result of the physical construction of the supercapacitor.
