ELECTRIC POWER SYSTEM, ELECTRIC POWER RECEPTION DEVICE, AND ELECTRIC POWER TRANSMISSION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To prevent falsification of information as to green electric power.

SOLUTION: An electric power system includes an electric power transmission device and an electric power reception device. The electric power transmission device includes: an electric power generation unit for generating electric power from renewable energy; an electric power measurement unit for measuring an amount of the electric power generated by the electric power generation unit within a predetermined period of time; and an electric power transmission unit for transmitting, to the electric power reception device, the electric power generated by the electric power generation unit within the predetermined period of time and information as to the electric power amount measured by the electric power measurement unit. The electric power reception device includes: an electric power reception unit for receiving the electric power transmitted from the electric power transmission device and the information as to the electric power amount transmitted from the electric power transmission device; a second electric power measurement unit for measuring an amount of the electric power received by the electric power reception unit within the predetermined period of time; a judgement unit for comparing the information as to the electric power amount received by the electric power reception unit and information as to the electric power amount measured by the second electric power measurement unit with each other and judging whether the electric power amounts agree with each other; and an electric power reception control unit for, when the judgement unit has not judged that the electric power amounts agree with each other, halting the reception of the electric power and the information by the electric power reception unit.
