Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application claims priority from Japanese Patent Application No. 2021-214154 filed on Dec. 28, 2021, which is incorporated by reference herein in its entirety. BACKGROUND The technology disclosed herein relates to an electric power supply-demand adjustment method for an electric power system, and to a management device for an electricity storage device. In recent years, there is demand for reducing carbon dioxide (CO2) emissions to reduce the load on the global environment, since CO2 is a global greenhouse gas. Examples of effective means capable of reducing CO2 emissions include obtaining electric power by using renewable energy such as solar power, waterpower, wind power, geothermal power, biomass, and so forth, and using shared vehicles. Japanese Patent Application Publication No. 2015-005205 discloses a system including means for calculating an electric power consumption amount of an electric vehicle between a first station and a second station, and an electric power consumption amount per person from a count of passengers riding the electric vehicle in this section, means for registering an electric power amount for a passenger of the electric vehicle to sell, and means for converting an electric power amount for the passenger to pay into a fare. According to this system, prior to boarding the electrical vehicle, a passenger of the electric vehicle makes notification regarding an electric power amount that can be sold, out of electric power obtained from an electricity generating device that the passenger may own, such as solar power electricity generation, and can use the electric vehicle by paying a monetary amount obtained by subtracting a monetary amount, obtained by selling electricity, from the fare for using the electric vehicle. Also, Japanese Patent Application Publication No. 2021-033736 discloses a control device of a vehicle equipped with a CO2 recovery device, in which, in a case where there is a passenger in the vehicle, the amount of carbon dioxide recovered by the CO2 recovery device is calculated, and an incentive is imparted based on this data. Described therein is that usage of vehicles equipped with CO2 recovery devices will be promoted. SUMMARY However, in the technology described in Japanese Patent Application Publication No. 2015-005205 and Japanese Patent Application Publication No. 2021-033736, description is made only on the user him/herself using the electric vehicle or the vehicle equipped with the CO2 recovery device, and there is no disclosure regarding usage by those other than that person (e.g., family or the like of the person). Accordingly, there is demand for providing a framework in which the user him/herself and the family thereof and so forth can also obtain gain, thereby further reducing the load on the global environment. With the foregoing in view, it is an object of the present disclosure to provide an electric power supply-demand adjustment method for an electric power system that reduces the load on the global environment. Another object thereof is to provide a management device that suitably implements this electric power supply-demand adjustment method. In order to solve the above problem, the technology disclosed herein provides the following electric power supply-demand adjustment method. The electric power supply-demand adjustment method disclosed herein is a method for an electric power system in which supply and demand of electric power on the electric power system is adjusted by inputting, from an electricity storage device that is capable of storing electric power generated using renewable energy, at least the electric power, to the electric power system. The electricity storage device is configured to be capable of inputting the electric power from the electricity storage device to the electric power system. The electric power supply-demand adjustment method includes acquiring usage history information indicating history of usage of a shared vehicle by a tracked person, registered in advance in a manner associated with an electric power provider that provides the electric power from the electricity storage device to the electric power system, notifying the electric power provider of the acquired usage history information of the tracked person, calculating an electric power amount to be input from the electricity storage device to the electric power system on the basis of notification of the usage history information, and causing the electricity storage device to input the calculated electric power amount to the electric power system. By providing a framework in which the tracked person that is registered in association with the electric power provider can safely use the shared vehicle, usage of the shared vehicle is promoted. Also, calculating the electric power amount to be input to the electric power system from the electricity storage device storing electric power generated using renewable energ
