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 .
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.
When a large number of EVs are charged simultaneously at an EV charging station, problems may arise from a substantial increase in peak power demand to the grid. The integration of an Energy Storage System (ESS) in the EV charging station can not only reduce the charging time, but also reduces the stress on the grid.
In , the power grid is assumed to have small-scale charging stations and solar panels. EVs’ charging and discharging behaviors are optimized to balance the renewable energy cycle and reduce energy costs. The EV charging and discharging cycles are also shortened to prevent battery degradation.
The downward SC of the PV and storage-integrated fast charging station consists of two parts, including the downward SC of EVs and the downward SC of centralized energy storage. At this point, the PV is entirely abandoned because it is responding to the remaining power of the grid.
The main components of the energy storage system (ESS) are a battery pack and an energy storage converter, whose primary purpose is to give the fast charging station the ability to respond to the time-sharing tariff by managing the energy storage system, smoothing out the peaks and valleys, and returning power to the grid.
