Power trading system and management apparatus

Abstract

The present invention provides a power trading system that executes power trading between a plurality of apparatuses, wherein at least one apparatus of the plurality of apparatuses includes a management unit configured to manage electric energy of a battery, and the management unit manages the electric energy of the battery by discrimination between electric energy derived from exhaustible energy and electric energy derived from renewable energy.

1 - 8 . (canceled) 
     
     
         9 . A power trading system that executes power trading, comprising:
 a power system network;   a plurality of apparatuses each of which includes a battery and a management unit,   wherein the management unit is configured to:
 manage electric energy charged in the battery, such that electric energy derived from exhaustible energy and electric energy derived from renewable energy are discriminated from each other, and 
 manage selling at least a part of the electric energy charged in the battery by supplying the at least a part to the power system network, so as to discriminate whether the at least a part is electric energy derived from exhaustible energy or electric energy derived from renewable energy. 
   
     
     
         10 . The system according to  claim 9 , wherein the management unit is configured to manage selling at least a part of the electric energy charged in the battery, by assuming that electric energy derived from exhaustible energy is preferentially soled over electric energy derived from renewable energy among the electric energy charged in the battery. 
     
     
         11 . A apparatus that is connected to a power system network, comprising:
 a battery; and   a management unit configured to manage electric energy charged in the battery, such that electric energy derived from exhaustible energy and electric energy derived from renewable energy are discriminated from each other,   wherein the management unit is configured to manage selling at least a part of the electric energy charged in the battery by supplying the at least a part to the power system network, so as to discriminate whether the at least a part is electric energy derived from exhaustible energy or electric energy derived from renewable energy.
