Abstract
A data center (DC) user device manages user power consumption in a time unit, and stores the user power consumption in a power consumption table. A DC provider device manages provider power consumption in a time unit and stores the provider power consumption in the power consumption table. A power retailer device measures provider power consumption for a certain period, and determines retailer power consumption when a measurement value of the provider power consumption is equal to a total value of all user power consumptions.
Claims15
A renewable energy certificate verification system configured to verify amortization of a renewable energy certificate, the renewable energy certificate verification system comprising:
- a data center (DC) user device assigned to a DC user;
- a DC provider device assigned to a DC provider;
- and
- a power retailer device assigned to a power retailer,
- the DC user device including:
- a power consumption management unit that manages user power consumption in a time unit;
- and
- a power consumption table,
- the power consumption table being configured to store the user power consumption,
- the DC provider device including:
- a power consumption management unit that manages a provider power consumption in a time unit;
- and
- the power consumption table,
- the power consumption table being configured to store the provider power consumption,
- the power retailer device including:
- a power consumption determination unit;
- and
- the power consumption table,
- the power consumption table being shared among the DC user device, the DC provider device, and the power retailer device,
- the power consumption determination unit of the power retailer device being configured to measure the provider power consumption in a certain period, and determine retailer power consumption when a measurement value of the provider power consumption is equal to a total value of all user power consumptions.
A method for verifying a renewable energy certificate to verify amortization of the renewable energy certificate using a renewable energy certificate verification system including a data center (DC) user device assigned to a DC user, a DC provider device assigned to a DC provider, and a power retailer device assigned to a power retailer, the method comprising:
- managing user power consumption in a time unit in the DC user device;
- storing the user power consumption in a power consumption table in the DC user device;
- managing provider power consumption in a time unit in the DC provider device;
- storing the provider power consumption in the power consumption table in the DC provider device;
- measuring the provider power consumption in a certain period in the power retailer device;
- and
- determining retailer power consumption when a measurement value of the provider power consumption is equal to a total value of all the user power consumptions in the power retailer device.
