Electric power controller, electric power management device, electric power control method, and electric power management system for trading and distributing electric power

An energy management device, comprising:

• an electric power management unit configured to generate an instruction that indicates a supply destination for electric power generated by an electric power generator;
• and
• a communication unit configured to:
• transmit the instruction to an energy control device that controls supply of the electric power to the supply destination, wherein the energy control device is connected to a storage battery module,
• receive electric storage amount information that indicates an electric storage amount stored in the storage battery module,
• wherein the energy control device determines a surplus power based on a difference between a generation amount of the electric power generated by the electric power generator and a charge amount of the electric power to charge the storage battery module;
• and
• wherein the energy control device distributes a first amount of the surplus power for personal consumption and a second amount of the surplus power for sale to the supply destination based on a determination that a maximum amount of the electric power required for the personal consumption is less than the surplus power.

An energy control method, comprising:

• receiving an instruction from an electric power management device, the instruction indicating a supply destination of electric power generated by an electric power generator;
• receiving electric storage amount information indicating an electric storage amount stored in a storage battery module;
• receiving a discharge amount discharged from the storage battery module to an electric power market;
• determining a surplus power based on a difference between a generation amount of the electric power generated by the electric power generator and a charge amount of the electric power required to charge the storage battery module;
• and
• distributing a first amount of the surplus power for personal consumption and a second amount of the surplus power for sale to the supply destination based on a determination that a maximum amount of the electric power required for the personal consumption is less than the surplus power.

An energy management system, comprising:

• an energy management device including:
• an electric power management unit configured to generate an instruction that indicates a supply destination for electric power generated by an electric power generator;
• and
• a first communication unit configured to transmit the instruction to an energy control device;
• the energy control device including:
• a power conditioner configured to:
• output the electric power generated by the electric power generator to a storage battery module;
• measure an amount of the electric power output to the storage battery module;
• and
• measure discharge amount of electric power discharged from the storage battery module;
• and
• a control unit configured to:
• determine a surplus power based on a difference between a generation amount of the electric power generated by the electric power generator and a charge amount of the electric power required to charge the storage battery module;
• and
• control the power conditioner to distribute a first amount of the surplus power for personal consumption and a second amount of the surplus power for sale to the supply destination based on a determination that a maximum amount of the electric power required for the personal consumption is less than the surplus power.
