Abstract:
1. A self-sustainable electric power grid, not depending on a large-scale power plant but also capable of coexisting with a known electric power system, comprising: a plurality of supplier/demanders of electric power, mutually connected via an electric power supply and demand line; each supplier/demander comprising one control device; at least one load device; and at least one device selected from the group consisting of electricity power generation devices and electricity storage devices; the control devices including circuitry that determines whether there exists in each respective supplier/demander an electric-power shortage or an electric-power surplus; wherein, in the case where an electric-power surplus is determined, the respective control device delivers electric power to other suppliers/demanders via the electric power supply and demand line; wherein, in the case where an electric-power shortage is determined, the respective control device accepts electric power from other suppliers/demanders via the electric power supply and demand line; wherein delivery and receipt of electric power is performed by moving a movable power generation device and/or a movable electrical storage device to another supplier/demander; and wherein each supplier/demander refers to information from the control device in another supplier/demander, and sets or changes operating conditions of the control device or devices of said each supplier/demander on the basis of the amount of electric power consumption which is estimated by the other supplier/demander.
