Where are EVCs coupling nodes located?
To realize the conversion of the charging load, renewable energy power and the charging and discharging power of energy storage equipment generated by the EVCSs set up in the transportation network in the distribution network node power, the two coupling nodes connected by the network coupling line are geographically located closely.
Why do we need energy storage devices?
The unstable output power can easily fail to meet the charging demand, and even threaten the steady operation of the power grid. The energy storage device can alleviate the fluctuation of renewable energy sources, and can also reduce the pressure of load undulation on the distribution network.
What is the charging and discharging strategy of energy storage device?
Eqs. (32), (33) indicate that the remaining energy will be stored in the energy storage device after the wind and solar output power meets the load demand power. The charging and discharging strategy of the energy storage device is that when the combined energy output cannot meet the load demand, the energy storage device will discharge.
