Abstract: Provided are a power brokerage method and a power brokerage system, and the power brokerage system stores encrypted power brokerage and trading information and a digitally signed hash value in a blockchain distributed ledger through a smart contract code running on a blockchain platform and allows the same to be retrieved. Also, the power brokerage system protects sensitive information related to a brokerage trading contract, a bid, and a settlement by allowing a participant participating in the power market to retrieve original data related to power brokerage and trading information from a power trading server and to compare and verify data forgery/falsification and, at the same time, ensures data integrity and transparency of a brokerage contract and trading.

Abstract: An apparatus for controlling a self-power consumption includes an information receiving unit configured to receive a power supply and demand situation and power price information through a wire/wireless communication network. The apparatus includes a self-power consumption control unit configured to compare the power supply and demand situation with a predetermined power situation and produce a control signal to control a plurality of appliances when it is determined that the power supply and demand situation is put in a state of emergency, or the power price exceeds a predetermined threshold. The apparatus includes a standby power status control unit configured to select one or more appliances of the appliances in response to the control signal and switch the selected appliances into a standby power state.

Abstract: A power metering apparatus, a power metering server, and a power metering method based on a blockchain are disclosed. Particularly, in order to simultaneously assure integrity and transparency of power metering data based on a blockchain, power metering data generated by measuring an amount of power generated by an energy source and a unique key are stored in a database linked to a power metering server, and a digitally signed hash value of the power metering data is stored in a blockchain node. Accordingly, disclosed are blockchain-based power metering system and method for preventing forgery and tampering of power metering data, solving a problem associated with a blockchain storage capacity that may occur when storing the power metering data, and protecting sensitive information on the power metering data.
