Power system, power receiving apparatus, and power transmission control method

A power receiving apparatus comprising:

• a power receiving unit receiving power transmitted from a power transmitting unit of a power transmitting apparatus and receiving information on a power amount transmitted from the power transmitting unit, the power transmitting apparatus including a power generating unit generating the power using renewable energy, a first power measuring unit measuring the power amount of the power generated by the power generating unit in a specified period, and the power transmitting unit transmitting the power generated by the power generating unit in the specified period and the information on the power amount measured by the first power measuring unit to the power receiving apparatus;
• a second power measuring unit measuring a power amount of the power received by the power receiving unit in the specified period;
• a determining unit comparing the information on the power amount received by the power receiving unit and information on the power amount measured by the second power measuring unit and determining whether the two power amounts match;
• and
• a power reception control unit operable when the determining unit has determined that the two power amounts do not match, to stop the power receiving unit from receiving the power and from receiving the information.

A power transmission control method comprising:

• generating, by a power transmitting apparatus, power using renewable energy;
• measuring, by the power transmitting apparatus, a power amount of the power generated in a specified period;
• transmitting, by the power transmitting apparatus, the power generated in the specified period and information on the power amount measured by the power transmitting apparatus to a power receiving apparatus;
• receiving, by the power receiving apparatus, the transmitted power and receiving the transmitted information on the power amount;
• measuring, by the power receiving apparatus, a power amount of the power received in the specified period;
• comparing, by the power receiving apparatus, the information on the power amount received by the power receiving apparatus and information on the power amount measured by the power receiving apparatus and determining whether the two power amounts match;
• and
• stopping, by the power receiving apparatus when it has been determined that the two power amounts do not match, reception of the power and reception of the information.
