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).
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 instance, the APP of TELD, that is, a leading charging facility manufacturer and operator in China, claims that the DC charging pile's advertised charging power of 60–150 kW is 60 kW, but the highest charging power it is capable of is about 90–100 kW.
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 .
