5 is a flowchart illustrating a method of generating monitoring information according to energy / carbon management according to an embodiment of the present invention.

Referring to FIG. 5, the energy / carbon control apparatus 120 receives power usage information (ie, measurement information) for each server from the power distributor 110 in step 510, and uses power usage for each server received in step 520. The information is generated and stored in the database 125.

In addition, the energy / carbon control apparatus 120 receives temperature information sensed by the temperature sensor from the power distributor 110 in step 530, and stores the temperature information received in step 540 in the database 125.

Naturally, the steps 510 to 520 and the steps 530 to 540 for generating power usage information and temperature information may be performed sequentially or simultaneously.

In operation 550, the energy / carbon control apparatus 120 generates various monitoring information by using the driving related information received from the power distributor 10. The monitoring information is, for example, information for monitoring information related to power usage, and the like may include demand forecast data, reference power usage, corrected reference power usage, carbon dioxide emission information, and scheduling information on power usage. The method of calculating the carbon dioxide emission by using the energy / carbon control device 120 using the power usage information will be described later with reference to FIG. 6.

In operation 560, the energy / carbon control apparatus 120 determines whether a request for providing monitoring information is received from the remote control terminal 130.

If a request for providing monitoring information has not been received, the process proceeds to step 510 and step 530 again.

However, if a request for providing monitoring information is received, the energy / carbon control apparatus 120 transmits the monitoring information to the remote control terminal 130 through the communication network in step 570.

Through the above-described process, the energy / carbon control apparatus 120 may collect various measurement information and equipment state information (eg, temperature information), and generate and provide monitoring information related thereto to the manager.

6 is a flowchart illustrating a method of calculating carbon dioxide emission according to an embodiment of the present invention. Each step illustrated in FIG. 6 may be a series of processes for calculating carbon dioxide emission information among monitoring information generated in step 550 of FIG. 5 described above.

The energy / carbon control apparatus 120 may generate carbon dioxide emission information in different ways depending on the type of greenhouse gas emission source. That is, it can be divided into direct and indirect sources according to whether the greenhouse gas is emitted from the source directly owned and controlled by the operator or whether the greenhouse gas is generated by the electricity purchased by the operator. For example, emissions from generators owned or controlled by a company, or from chemical production activities in a facility, can be defined as direct sources, and greenhouse gas emissions associated with the production of energy sources purchased by companies for direct consumption. May be defined as an indirect source.

First, the carbon dioxide emission by the direct emission source may be calculated by Equation 2 below.

Here, the units of consumption for each fuel are solid t, liquid kL, and gas kNm ³ , and the units of calorific value are solid kcal / kg, liquid kcal / L, and gas kcal / Nm ^3, respectively. 1kcal is 4.186kJ, 1ton is 1,000kg, and 1TJ is 106kJ.

Next, the carbon dioxide emissions of the indirect source can be calculated by the following equations (3) and (4), respectively. That is, Equation 3 is for estimating carbon dioxide emission according to power consumed by the IT device, and Equation 4 is carbon dioxide emission due to the use of heat (steam) and refrigerant supplied to the air conditioning facilities of the server room and / or the server section. It is to calculate.

Referring to FIG. 6, in order to calculate carbon dioxide emissions, the energy / carbon control apparatus 120 determines whether power usage information received from the power distributor 110 is directly for an emission source in step 610.

If it is for a direct emission source, the flow proceeds to step 620 where the carbon dioxide emission is estimated in the manner according to Equation 2 above.

However, if it is not for the direct source, the flow proceeds to step 630, where the energy / carbon control device 120 determines whether the power usage information received from the power divider 110 is for the power consumption of the IT device.

If it is for the power consumption of the IT device, the flow proceeds to step 630 where the carbon dioxide emission is calculated in the manner according to Equation 3 above.

However, if it is not about the power consumption of the IT device (i.e. by the use of heat and refrigerant supplied to the air conditioning facility for the server room and / or the server section), proceed to step 640 and in the manner according to Equation 4 above. CO2 emissions are estimated.

7 is a flowchart illustrating a load transfer method between server devices according to an exemplary embodiment of the present invention.

Referring to FIG. 7, the energy / carbon control device 120 receives operation rate information for each server device from the power distributor 110 in step 710.

In operation 720, the energy / carbon control apparatus 120 determines whether there is a server device that is driven at an operation rate equal to or lower than a previous reference value designated for efficient management of power usage by referring to the received operation rate information. The previous reference value can be specified as, for example, 20% utilization rate, which causes power usage regardless of the high and low operating rate, so that the load of the server with low utilization rate is concentrated and processed by other server devices. To minimize this.

In step 730, the energy / carbon control device 120 determines whether there is a server device that can afford to transfer the load of the server device having an operation rate of less than the previous reference value. Of course, the server device to be transferred may be present in the same server section or in a different server section as the server device to which the load is to be transferred.

If there is no server device to transfer the load (for example, if only the server device that is lower than the previous reference value remains in operation, other server devices cannot afford the operation rate to transfer the load, etc.) In step 710, the process returns to step 710 again.

However, if there is a server to transfer the load, the energy / carbon control device 120 generates a server change control signal for processing the load in another server device in step 740 and transmits to the power divider 110 do.

On the other hand, the technical idea of the present invention can also be applied to a computer-readable recording medium containing a computer program for performing the function of the energy / carbon control device 120 according to the present embodiment. In addition, the technical idea according to various embodiments of the present invention may be embodied in computer-readable code form recorded on a computer-readable recording medium.
