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.

Abstract: A method of controlling an energy storage and an energy storage controlling apparatus are disclosed. The method may include dividing an energy storage of large capacity into virtual energy storages corresponding to respective users based on a required energy amount and a period of use of an energy storage of each of the users, and integrally controlling, for each time, the virtual energy storages corresponding to the respective users based on a management schedule of the energy storage of each of the users.
