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.
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 .
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).
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 power supply and distribution system, charging system, monitoring system, energy storage system, and photovoltaic power generation system are the five essential components of the PV and storage integrated fast charging stations. The battery for energy storage, DC charging piles, and PV comprise its three main components.
The energy relationship between the SC of electric vehicles (EVs), the SC of centralized energy storage, and the PV power generation is constructed to solve for the upward SC and downward SC of the entire charging station based on the detailed explanation of the electrical structure of the PV and storage integrated fast charging station.
