Abstract
In the trend toward decarbonization, electric vehicles are also being introduced into the home delivery business, but the devel-opment of charging facilities is a challenge. In addition, dynamic pricing, in which electricity rates fluctuate depending on the time of day, is about to be introduced due to oversupply of daytime electricity from solar power generation. We consider the efficient use of surplus electricity during the day for delivery business. This study quantitatively demonstrates the effect of dy-namic pricing by using a mathematical optimization model to determine the optimal delivery route and charging plan in response to the fluctuating electricity prices. As a result, effects such as an increase enroute charging by daytime electricity, reduction in charging costs, and promotion of renewable energy use were observed. It is also shown that by taking the next day’s electricity prices into account, it is possible to plan more effective use of inexpensive electricity, and greater effects can be seen.
