要約(日本語): Shifting the charging of electric vehicles to daytime or midnight has the possibility to suppress the variations in voltage and power flow in distribution systems. For evaluating its impact, the authors simulated the shifted charging load curves based on traffic simulation, and calculated the power flow and voltage in the distribution line integrating these curves. The results show that charge shifting can reduce the forward power flow at evening and the reverse power flow from photovoltaic (PV) generation at noon, but it may also cause new peaks at night or violate the thermal capacity or voltage limits of the distribution system.
