| Outline of Final Research Achievements |
In future distribution networks with high penetrated photovoltaic (PV) generations, intermittent PV generations must be effectively utilized for charging electric vehicles (EVs) with batteries. The purpose of this research project is to resolve both the voltage-rise problems by PV integration and the voltage-drop and the distribution line capacity problems by fast EV charging simultaneously. Therefore, a new methodology for evaluating the fast EV chargeable capacity under the voltage constraints in medium-voltage and low-voltage distribution networks was developed based on the short-term prediction values of the PV output. Furthermore, assuming a case that the PV output is suddenly reduced by cloud passing, the fast EV chargeable capacity was evaluated considering the reactive power support from roof-top PV inverters.
