Therefore, voltage control and reactive power management tools are used using a genetic algorithm to provide fair charging conditions for EVs in all charging stations in the distribution network. Here, it is assumed that the charging time periods are 15 min and that EVs enter the charging stations in a specific time period to get to full charge.
In distributed voltage control, the distribution network with EVs and PVs connected is first partitioned into several regions based on the similarity of bus voltage sensitivity. Then, regional voltage control is applied to each regional distribution network via the active and reactive power control of their member EVs and PVs [34, 35].
According to the day-ahead forecasting of preliminary load consumptions, PV generations, and EV charging demands (Figure 11, Figure 12 and Figure 13), the grid voltage distribution patterns before the control activation can be estimated via the time series power flow simulations, as illustrated in Figure 15.
Proper management in shaping the charging stations of EVs in the distribution system can create a suitable opportunity to help the energy and ancillary services power market, which can potentially present a challenge for the electricity network.
In this control method, the charging and discharging of EVs are used as a load in the power system to fill the valleys in the voltage profiles of the network. In ref 27, the optimal coordination of the EVs charging into the power system is carried out with the aim of total loss minimization in the power system.
Thus, it is very important to consider and control charging for electric vehicles in the distribution grid, so with proper charge management of EVs, due to the connection of a large number of EVs to the network, they will have significant effects on the distribution network.
