Abstract

A server manages power balancing resources electrically connected to a power network. The server includes a processor. In response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, the processor predicts a power supply and demand balance on the power network for the date and time of travel, based on power supply and demand performance information of the power network. In response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel, the processor provides the user suggestion to keep the vehicle connected to the power equipment on the date and time of travel and a reward for the vehicle responding to a request to adjust the power supply and demand balance.

First claim

What is claimed is:

1 . A server that is configured to manage power balancing resources electrically connected to a power network, the power balancing resources including power equipment configured to supply power from a vehicle to the power network and to charge the vehicle from the power network, the server comprising:
a processor; and a memory storing a program that is executable by the processor, wherein the processor is configured to, in response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, predict a power supply and demand balance on the power network for the date and time of travel according to the program, based on power supply and demand performance information of the power network; the processor is configured to access information regarding public transportation during the travel time period for the day of travel; the processor is configured to generate travel route information indicating a travel route from the departure point to the destination point based on the travel schedule and the information regarding public transportation; the processor is configured to, in response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel, provide the user at least one of:
suggestion to keep the vehicle connected to the power equipment on the date and time of travel; and
a reward for the vehicle responding to a request to adjust the power supply and demand balance.

2 . The server according to claim 1 , wherein the processor is configured to suggest traveling from the departure point to the destination point using public transportation as the suggestion.

3 . The server according to claim 2 , wherein the processor is configured to:
create a first travel route using the vehicle and at least one second travel route using the public transportation, based on the travel schedule; and present the first travel route and the at least one second travel route together with required travel time of each travel route to the user.

4 . The server according to claim 3 , wherein the processor is configured to:
calculate, for each of the first travel route and the at least one second travel route, power consumption per occupant during the required travel time; set priorities for the first travel route and the at least one second travel route in ascending order of the power consumption per occupant; and present the first travel route and the at least one second travel route to the user in descending order of priority.

5 . The server according to claim 1 , wherein the processor is configured to:
predict, based on the power supply and demand performance information, a time period during which the power supply and demand balance is going to be adjusted on the date and time of travel; and present the predicted time period to the user.

6 . The server according to claim 1 , wherein the processor is configured to present information on the reward to the user.

7 . The server according to claim 1 , wherein the processor is configured to, when the processor receives input of an attribute of the user together with the travel schedule, determine whether to provide the user the suggestion depending on the attribute of the user.

8 . The server according to claim 7 , wherein:
the processor is configured to provide the suggestion when the user has a first attribute, and not to provide the suggestion when the user has a second attribute; the first attribute includes able-bodied; and the second attribute includes at least one of following: with disabilities, elderly, pregnant, and having a child.

9 . The server according to claim 8 , wherein the processor is configured to:
create a first travel route using the vehicle and at least one second travel route using public transportation, based on the travel schedule; calculate, for each of the first travel route and the at least one second travel route, the reward to be provided to the user and physical burden on the user; set priorities for the first travel route and the at least one second travel route in descending order of the reward when the user has the first attribute; set priorities for the first travel route and the at least one second travel route in ascending order of the physical burden when the user has the second attribute; and present the first travel route and the at least one second travel route to the user in descending order of priority.

10 . A power supply and demand balancing method in which power balancing resources electrically connected to a power network is managed, the power balancing resources including power equipment configured to supply power from a vehicle to the power network and to charge the vehicle from the power network, the power supply and demand balancing method comprising:
in response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, predicting a power supply and demand balance on the power network for the date and time of travel, based on power supply and demand performance information of the power network; accessing information regarding public transportation during the travel time period for the day of travel; generating travel route information indicating a travel route from the departure point to the destination point based on the travel schedule and the information regarding public transportation; in response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel, providing the user at least one of:
suggestion to keep the vehicle connected to the power equipment on the date and time of travel; and
a reward for the vehicle responding to a request to adjust the power supply and demand balance.

11 . A server that is configured to manage power balancing resources electrically connected to a power network, the power balancing resources including power equipment configured to supply power from a vehicle to the power network and to charge the vehicle from the power network, the server comprising:
a processor; and a memory storing a program that is executable by the processor, wherein the processor is configured to, in response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, predict a power supply and demand balance on the power network for the date and time of travel according to the program, based on power supply and demand performance information of the power network, and the processor is configured to, in response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel:
suggest the user to travel from the departure point to the destination point using public transportation;
keep the vehicle connected to the power equipment on the date and time of travel;
create a first travel route using the vehicle and at least one second travel route using the public transportation, based on the travel schedule; and
display, on a touch panel display of a user terminal that communicates with the server, the first travel route and the at least one second travel route together with required travel time of each travel route to present each travel route to the user.
