  • Patent number: 9595189
    Abstract: Adjustment values, including a station stop time or a departure interval, are set for each vehicle. Next, the set adjustment values and a traveling pattern are used to calculate the power consumption by and regenerative power from each vehicle when in operation for each time point. Next, the total vehicle power at each time point is calculated by subtracting the total regenerative power from braking vehicles from the total power consumption by powering vehicles one a per time point basis. Next, a positive value or a negative value is extracted from the total vehicle power at each time point. Next, an evaluation value is calculated using the absolute value of the total of the extracted values. Next, adjustment values that produce the smaller evaluation value are identified.

    Abstract: This electricity-demand prediction device is provided with a data reception unit, an individual-model generation unit, and a demand-prediction computation unit. Vehicle probe data in which specific driving states are recorded is inputted to the data reception unit, and on the basis of said vehicle probe data, the individual-model generation unit generates an individual model for each specific vehicle or for each user of a specific vehicle. Said individual models represent correlations between historical values associated with factor information regarding factors in decisions to charge specific vehicles at a specific charging facility and historical values representing electricity demand for said specific vehicles at said specific charging facility. The demand-prediction computation unit computes a predicted electricity demand for the specific vehicles at the specific charging facility on the basis of the generated individual models.
