Korea 's electric energy consumption has been steadily increasing since the 1970s due to the improvement of living standards, the pursuit of convenience and the intermediate energy production - oriented energy rather than the non - industrial structure. The price of electricity, which is the primary energy, continues to rise, and the cost of electricity increases. However, electricity prices, which are secondary energy produced by processing the electricity, have only recently risen, but the government is relatively free from gas and oil Has continued.

On the other hand, the imbalance in the relative price of energy caused by electricity prices that do not reflect actual energy prices is giving a distorted signal to each economic entity 's consumption and investment, causing side effects. For example, in the domestic manufacturing industry, overcapacity investment is taking place mainly in the energy consuming industry due to the relative low price of electricity. In addition, the use of electric heating and cooling in general buildings is increasing rapidly. Recently, the demand for energy conversion, in which the heating of building, which was using gas or oil, is gradually replaced by electricity is also increasing rapidly.

As a result, there is a vicious cycle in which electric power demand must be renewed every year and the power plant must be built continuously. However, it is very difficult to build a large capacity power plant due to domestic and foreign incidents such as the anxiety of the people and the parts irregularity about the nuclear power plant after the recent incident in Japan. The bigger problem is that as the power system grows, the construction of transmission lines and substations, which are essential for the transmission of electricity, is suffering from environmental problems and local civil complaints.

Referring to FIG. 1, an electricity bill saving system according to an embodiment of the present invention may include a usage power meter 120, a power supply server 200, and a power demand management device 300.

Here, the used power meter 120 may measure the amount of power used by at least one power consumer 10 having a plurality of loads 110-1 to 110-N consuming power. In one example, the used power meter 120 can measure the used power amount of at least one power demanding device 10 having a plurality of loads 110-1 to 110-N consuming power in real time. In another example, the used power meter 120 may periodically measure the amount of power used by at least one power consumer 10 having a plurality of loads 110-1 to 110-N consuming power.

In another example, the used power meter 120 may be provided in the power demander 10 to measure the amount of power used by the power demander 10, as shown in the figure. In another example, the used power meter 120 may be provided in a power supply source 20 or a load management company 30, which will be described later, to measure the amount of power used by the power consumer 10. In another example, the used power meter 120 may be separately installed at a location different from the power demanding place 10, the power supplying place 20, and the load managing company 30 to measure the amount of power used by the power demanding place 10 .

The used power meter 120 may include an electronic meter capable of performing remote meter reading on the amount of power used by the power consumer 10, a maximum demand power controller, or a peak controller. However, the present invention is not limited thereto. Any device capable of measuring the amount of power can be included.

The power source server 200 may be included in the power source 20. The power supply unit 20 may be a subject that can reduce the cost and stabilize the power supply and demand by improving the load factor by reasonably adjusting the power demand through the demand side management (DSM).

The demand management (DSM) can mean all activities of the electric power company to induce consumers 'electric usage patterns in a reasonable direction to meet consumers' electric energy service needs at a minimum cost. Demand Response, DR) and energy efficiency (EE). The demand management (DSM) may be an upper concept encompassing load management (load management) as a concept corresponding to the previous supply side management (SSM) which has been focused on the expansion of the power supply facilities.

The power supply source 20 is a company that purchases electricity from a power generation company to sell electricity (for example, KEPCO), a system operator (for example, KEPCO) that operates a power system, And a power generation company (for example, a private power generation plant) that supplies power to the consumer.

Then, such a power supply source 20 can calculate the electricity rate, and can charge the electricity demander 10 with the electric rate calculated according to the contract.

In addition, the power supply source server 200 may be connected to the used power meter 120 through the communication network 1. In addition, the power supply source server 200 can receive the measured power consumption of the power consumption source 10 measured by the used power measurement device 120.

In one example, the power source server 200 may receive the measured amount of power used by the power demander 10 from the used power meter 120 in real time. In another example, the power source server 200 may periodically receive the amount of power used by the power demand source 10 measured from the power meter 120.

Here, the communication network 1 is a communication network 1 which is a high-speed period network of a large communication network capable of a large-capacity, long-distance voice and data service. The communication network 1 is a next generation including WiFi, Wibro and Wimax for providing Internet or high- It can be a wireless network.

If the communication network 1 is a mobile communication network, it may be a synchronous mobile communication network or an asynchronous mobile communication network. As an embodiment of the asynchronous mobile communication network, a WCDMA (Wideband Code Division Multiple Access) communication network is exemplified. In this case, although not shown in the drawing, the mobile communication network may include a Radio Network Controller (RNC). Meanwhile, although the WCDMA network is taken as an example, it may be a next generation communication network such as a 3G LTE network, a 4G network, and a 5G network, or an IP network based on other IPs.

In addition, the power supply source server 200 can store the data in a database using the amount of power consumed by each power consumer 10, based on the amount of power consumed by each power consumer 10 transmitted from the used power measurer 120.

In addition, the power supply source server 200 can calculate the current monthly electricity charge for each power consumer 10 by using the amount of power used by the database of the demanded power consumers 10. That is, the power source server 200 can use the amount of power used by each of the power demanders 10 that have been converted into the database, including the current month, when calculating the current month's electricity bill.

As described above, the power supply source server 200 can calculate the electricity tariff, and the power supply source 20 can charge the electricity demand source 10 with the electricity tariff calculated by the power source server 200 have.

Referring to FIG. 2, an electricity rate applied to an embodiment of the present invention is a charge imposed in exchange for using electric power by the power demanding entity 10, and includes a basic charge, a power usage charge (or a power charge, Other fees may be included. That is, the electricity rate may be calculated by adding other fees to the sum of the base rate and the power usage rate, as shown in the following Equation (1). Here, the other charges can be calculated using the following equation (2).

[Equation 1]

Electricity charge = Basic charge + Electricity consumption charge rate + Other charge

&Quot; (2) "

Other Fares = Power Factor Charge + Value Added Tax + Power Industry Based Fund

Referring to Equations (1) and (2), the electricity rate may be calculated differently depending on the electricity supply system or contract type. That is, the electricity rate may include a low-voltage electricity rate or a high-voltage electricity rate depending on the electricity supply system.

The electric charges may be classified into electric charges for residential use (for example, residential use), electric charges for general use (for example, public use or business use), electric charges for industrial use (for example, mining or industrial use) (For example, a school or a museum), an electricity bill, an agricultural bill (for example, for agriculture or fishery), an electricity bill or a street bill (for example, a street lamp or security bill, etc.)

In addition, the electricity rate may be calculated differently by month and time zone. Further, the electricity bill can be estimated in advance through the contract between the power supply source 20 and the load management company 30 or the power consumption source 10.

The basic charge may be calculated on the basis of the contract power that the electric power supplier (for example, KEPCO) 20 agrees to supply to the electric power consumer (for example, electric consumer) 10.

That is, the basic charge can be calculated using the maximum demanded electric power amount of the electric power consumer 10 during the predetermined basic charge calculating period calculated based on the electric power used by the electric power consumer 10 measured by the electric power consumption measuring device 120 have.

On the other hand, the electric power usage charge rate is a rate for the electric power consumption used by the electric power consumer 10 in the current month, and may be calculated every month on the basis of the used electric energy used in the electric power consumer 10 in the current month.

Meanwhile, the power factor rate among the above-mentioned other charges is calculated based on whether the power factor of the loads 110-1 to 110-N provided to the power demander 10 exceeds or does not exceed the previously calculated reference power factor, And a charge added to or subtracted from the sum of the basic charge and the electric power usage charge of the battery. Here, the reference power factor may be 90%, but is not limited thereto and can be changed.

In one example, the power factor rate is calculated by multiplying the base rate of the power consumer 10 by the power of the power source 10, when the power factor of the loads 110-1 to 110-N provided in the power consumer 10 exceeds a previously calculated reference power factor. Can be subtracted from the sum of usage charges. Accordingly, the current monthly electricity charge of the power consumer 10 can be reduced by the power factor rate.

In another example, when the power factor of the loads 110-1 to 110-N provided in the power consumer 10 is less than the previously calculated reference power factor, the power factor rate is lower than the base rate of the power consumer 10, Can be added to the sum of usage charges. Accordingly, the current monthly electricity charge of the power consumer 10 can be added by the power factor rate.

On the other hand, the above-mentioned value-added tax and power industry-based fund among other charges may be a charge determined by law. At present, the VAT rate is 10%, while the electric power industry-based fund is 37% of the total of the base rate and the electricity usage rate, but the VAT rate and the electricity industry based fund can be changed by law.

Referring to FIG. 1, the power supply source server 200 calculates a predetermined basic charge calculation period for calculating a basic charge of the current month's electric charge using the electric power consumption amount of the electric power consumer 10 measured by the electric power consumption measuring device 120 And calculates an average used power amount that is the maximum of the calculated average used power amount of the power demand place 10 as the maximum demanded power amount of the power demand place 10 .

In another example, the power supply source server 200 uses the amount of power consumed by the power consumer 10 measured by the used power meter 120 to determine the number of months in January, February, July, August Calculates the average used power amount of the power demanding place 10 every 15 minutes in September and the month of the meter reading and calculates the average used power amount which is the maximum of the average used power amount of the calculated power demanding place 10 to the maximum demand of the power demanding place 10 Based on the maximum demanded electric power amount of the electric power demanding unit 10, the basic charge of the electricity charge of the current month can be calculated.

In another example, the power supply source server 200 uses the average power consumption of the power consumer 10 every 15 minutes from the immediately preceding 12 months including the survey month using the power consumption of the power consumer 10 measured by the power consumption measuring device 120 It is possible to calculate the amount of electric power and calculate the average used electric power amount which is the maximum of the calculated average electric power consumption amount of the electric power using place 10 as the maximum demanded electric power amount of the electric power consuming place 10, Based on this, it is possible to calculate the base rate among the electricity rates of the current month.

In another example, the power supply source server 200 uses the amount of power consumed by the power demanding unit 10 measured by the used power measuring unit 120 to calculate the amount of power used by the power demanding unit 10, which is the maximum at 12 months immediately preceding the surveying month It can be calculated based on the maximum demanded power amount of the power demanding unit 10 and the base charge amount of the current monthly electricity based on the maximum demanded power amount of the power demanding unit 10 can be calculated.
