BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a power management system, a control device, and a method, specifically to a technology for utilizing power.

Description of the Related Art

Considerations are made to store and utilize power generated at a power plant in ordinary times, at a base prepared for disasters and the like (Japanese Patent Laid-Open No. 2016-092867).

According to the technology described in Japanese Patent Laid-Open No. 2016-092867, only power that is generated at a power plant provided in a base is stored at the base. Therefore, power that is generated at regionally distributed facilities such as solar panels or power that is stored at regionally distributed places cannot be effectively used.

SUMMARY OF THE INVENTION

The present invention provides a technology for effectively using power that is present in a regionally distributed manner.

According to one aspect of the present invention, there is provided a power management system comprising: a holding unit capable of holding power in the form of storable energy, a supply unit configured to supply power procured from a contractor to the holding unit, and a setting unit configured to set a utilizable range of storable energy held by the holding unit, wherein if an amount of storable energy held by the holding unit exceeds a predetermined amount, the setting unit sets an excess of the storable energy exceeding the predetermined amount as utilizable storable energy.

Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).
