Description

Power usage and cost verification system and method thereof

[0001] The present invention relates to a system and method for verifying power use and cost accordingly on the power demand side. In more detail, it verifies whether the electricity use and cost to be paid by the electricity demand side of buildings, collective residential facilities, business sites, etc. are appropriate in comparison with the electricity supply side's pricing, and if not appropriate, appropriate electricity use information and costs are calculated. It relates to a power use and cost verification system and method therefor.

The power demand side makes a kind of contract with the power supply side regarding power use. The power supply side sets the cost standards for power supply and power use and presents them to the power demand side. Based on that, it is determined as contract power by selecting between the transformer facilities to be applied to the power demand side and those calculated as the electricity usage facilities. For voltages above high voltage, optional (Ⅰ, Ⅱ, Ⅲ) rates can be selectively applied, and the selected rate can be changed to another optional rate after one year has elapsed. When the maximum demand power is less than 30% of the contract power, 30% of the contract power is applied as the applied power. In the case of receiving electricity at low voltage, an additional charge is levied for each 1kW of contract power exceeding 450kWh per month. If the peak of the contract power of 20kW or more exceeds the contract power, the imposition of an excess usage surcharge is announced in the first month exceeding the contract power, and 150% to 250% of the unit price of the electricity rate or basic charge for the excess power or excess power from the second month is charged as an overuse surcharge.

Under the standard presented by the power supply side, the power demand side sets the contract power and makes a contract, and the basic fee for power usage is determined according to the contract power, and the cost is calculated and paid according to the power usage.

However, the power demand side overestimates the initial contract power and uses power far less than the contracted power. There are many cases where you are paying for

Inventions have been developed to solve these problems of power use and cost. Korean Patent Publication No. 10-2010-0037430 (published on April 09, 2010) discloses an invention of a contract power and electricity rate calculation simulation system, and an implementation method thereof.

In the disclosed invention, the customer selects a model of an electric device currently in use or is expected to be used, enters the annual usage period and daily usage time for each model to calculate the expected maximum power demand, and multiplies the maximum power demand by the expected increase rate in future use It is a configuration in which contract power can be calculated and the lowest rate system can be selected by simulating the expected electricity rate by applying the calculated contract power to the calculation of the electricity rate in use. According to the disclosed invention, the customer directly inputs the electric device that he or she uses or plans to use into the web program to simulate the exact expected electricity price, calculates the contract power appropriate for the actual usage, and establishes a specific future power use plan. This invention has the effect of improving the customer's reliability as the customer directly calculates the electricity rate without contacting the power company.

However, the disclosed invention calculates the expected maximum demand power based on the annual usage period and daily usage time of the electric device models and calculates the contract power by reflecting the expected increase rate of use. There is a problem in that there is no difference from the conventionally suggested standard for calculating contract power.

In addition, the invention of the contract power recommendation apparatus and method of Republic of Korea Patent No. 10-1740661 (registration date: May 22, 2017) is disclosed.

The patented invention provides an apparatus for recommending contract power for a specific retail store, comprising: a receiving module configured to receive variable data of the specific retail store and power usage data and variable data of at least one other retail store; After calculating the peak power by using the power usage data of the at least one or more other retail stores received by the receiving module, the correlation between the variables of the at least one or more other retail stores received by the receiving module and the calculated peak power a correlation analysis module that analyzes and selects data of a variable indicating a correlation greater than or equal to a threshold; a recommendation model generation module for generating a contract power recommendation model based on statistical analysis using the power usage data of the at least one or more other retail stores and the data of the variable selected by the correlation analysis module; and a recommendation module for recommending contract power for the specific retail store using the variable data of the specific retail store and the contract power recommendation model, wherein the correlation analysis module moves in units of time smaller than a reference time and includes a plurality of Calculating the power of a reference time unit and determining the maximum value among them as the peak power, the reference time is a time when the electricity provider determines a contract power violation, and the correlation analysis module includes: In calculating the power, the power usage data for a plurality of reference times is calculated using the power usage data, and the calculated power usage for each reference time is converted into the power usage for the power amount unit time, and each converted power amount unit It is an invention in which the power consumption during time is the power of each reference time unit.

The patented invention is an invention for recommending contract power of a specific retail store in a statistical method using variable data of a specific retail store, power usage data of at least one or more other retail stores, and variable data. However, there is a problem in recommending contract power as an estimate because the statistical method and the contract power calculation method through correlation analysis do not take into account the complicated rated power consumption, used power, and energy efficiency of the fully-equipped facility.

Therefore, the verification target data stored by classifying the power usage verification target in detail, the usage facility power data including the rated power consumption and average power usage reflecting the energy efficiency of the electricity using facility used in the classified verification target, and the use Maximum demand power data calculated based on facility power data, charge applied power data calculated based on the used facility power data and maximum demand power data, monthly available power data calculated based on the existing contract power, and An invention capable of calculating the power use and cost of a verification target using various data including monthly maximum usage data, usage rate data calculated based on this data, and spare rate data collected based on the verification target data is desired. .

In addition, the electricity rate calculation and management unit 1700 compares the value corresponding to 30% of the contract power calculated by the rate applied power information management unit 1400 and calculates the deviation when the value of the maximum power demand is small, and , the unit electricity rate applied to the verification target is multiplied by the above deviation to convert the electricity rate amount.

In addition, the excess charge information management unit 1800 of the operating computer 100 exceeds a value corresponding to 30% of the contract power generated during a certain period of the verification target (for example, the immediately preceding year or two years). Check if the peak power value exists.

It is confirmed that the operating computer 1000 does not have a peak power value exceeding a value corresponding to 30% of the contract power generated during a certain period of the verification target (eg, one or two years immediately preceding). In this case, the amount converted from the appropriate contract power of the verification target calculated in the above process is generated as verification target power use and cost verification information and provided so that it can be confirmed in the user interface of the user terminal 3000 .

Referring to Table 1 above, on the premise that the verification target (A) is using general high-voltage equipment power and the rate is subject to Option I, Since this 1,000KW corresponds to 25% of the contract power (4,000KW), it appears to be less than 30% of the contract power (standard on the power supply side) (1,200KW), and a converted amount (1,600 thousand won) is generated from the electricity bill. Therefore, it is required to change the contract power based on the maximum demand power (1,000KW). Since the calculation of contract power to be changed here is contract power to be applied in the future, energy efficiency class, standby power reduction certification, usage period and monthly usage time of high voltage electricity using facilities subject to verification based on the maximum demand power (1,000KW) It is desirable to calculate by reflecting the information.

However, for example, if the maximum peak power of a specific month has been checked as 1,500KW during the set period, this is a figure exceeding 30% of the contract power, so it is judged that it is difficult to change the contract power.

In addition, when the power supply type of the verification target recognized by the operating computer 1000 is a low voltage facility, first, support information to be applied to the low voltage facility for verification of the verification target is prepared, the operating computer 1000 prepares For support information related to low voltage facilities, whether the monthly usage of the power demand side exceeds 450 times the contracted capacity, and if the monthly usage is significantly less than the contracted power, the adequacy of the contracted power is reviewed through load facility analysis, and the appropriate contracted capacity It may include calculation criteria information and the like.

In addition, it may further include additional charge standard information based on the addition or reduction of the charge according to the power factor of the used power and the additional charge payment standard information according to the excess of the peak power.

The verification target information management unit 1150 of the operating computer 1000 brings information about the current contract power contracted with the power supply side from among the stored verification target information. The monthly available electricity amount information management unit 1450 calculates the monthly available electricity amount on the power demand side by reflecting 450 times the support information based on the contract power of the verification target. The monthly maximum consumption information management unit 1500 brings the actual checked maximum monthly electricity consumption information of the verification target. The usage rate calculation information management unit 1550 calculates the usage rate based on the monthly available power amount and the monthly maximum usage information. The appropriate contract power calculation and management unit 1650 calculates appropriate contract power information based on the contract power and the usage rate information. The electricity rate calculation and management unit 1700 calculates a deviation between the value of the appropriate contract power and the value of the contract power, and applies the unit electricity rate to the deviation to convert the amount of the electricity rate.

The amount converted from the appropriate contract power of the verification target calculated in the above process is generated as verification target power use and cost verification information, and provided so that it can be confirmed in the user interface of the user terminal 3000 .

An example of the case where the verification target described above is a low-pressure facility will be described with reference to the contents disclosed in Table 2 below.

Referring to Table 2 above, the electricity consumption of the verification target (B: 2 industrial cases) corresponds to 2.4% and 0.9% of the contract power, and the appropriate contract power calculated based on this corresponds to 1KW. In addition, it was verified that the conversion amount of the electricity rate calculated based on the electricity consumption amounted to KRW 197,000 and KRW 246,000, so it was necessary to change the contract power based on the appropriate contract power of 1KW.

Here, in relation to the converted amount of the electricity rate, the value set as the change standard of the contract power may be used. For example, when the converted amount of electricity is 10% or more of the total electricity price, verification information can be provided to review the change of contract power.

In addition, when the power demand side maintains the contract power of the high-voltage facility and the low-voltage facility, respectively, for these complex facilities, verification in terms of electricity rates can be performed based on the support information of the power supply side.

For example, assuming that the examples in Tables 1 and 2 are maintained by one power demand side, looking at the application status of the selective rate plans I, II, and III, in the case of the low voltage facility (two for industrial use) If the electricity usage time is expected to be less than 200 hours per month, it is confirmed that the optional rate I is advantageous to the electricity demand side in terms of electricity rates.

In addition, since the usage rates of the low-voltage facilities (two for industrial use) in Table 2 are only 2.4% and 0.9%, it is confirmed that it is advantageous in terms of electricity rates to include them in the general high-voltage of Table 1 rather than the industrial account.

Table 3 shows that the electricity demand side of Table 1 and Table 2 is the same, and the electricity in the case of using the low-voltage equipment in Table 2 (2 cases for industrial use, Option Ⅱ) as it is, and when the general high voltage for industrial use and the rate are changed to Option I Shows the rate calculation result.

The above-described embodiment of the power use and cost verification system of the present invention is applied to a verification target currently using power.

Subsequently, the appropriate contract power calculation and management unit 1650 may calculate the appropriate contract power by applying a margin ratio to the calculated value of the maximum power demand. Here, as for the margin applied to the calculation of the appropriate contract power, the appropriate contract power can be calculated by applying a standard (eg, 50%) determined in the support information of the power supply side, but preferably, the margin ratio information management unit 1600 is The average value of the spare rate information of verification targets corresponding to various similar groups provided or collected by the spare rate information providing computer 7000 may be calculated and applied to the calculation of the appropriate contract power of the verification target.

The method of applying the margin ratio can also be applied to the calculation of the appropriate contract power of the verification target currently using power.

In addition, if the verification target that is scheduled to use power is a low-voltage facility, first, the maximum demand power is calculated by reflecting the energy efficiency rating information and standby power reduction certification information in relation to the electricity-using facilities to be verified, and the The contract power is calculated by applying the margin ratio.

When the contract power is calculated, the monthly available power information management unit 1450 calculates the monthly usable power by applying 450 times according to the standard set by the power supply side based on the contract power.

Next, the monthly maximum usage information management unit 1500 predicts the monthly usage time information of the electricity using facilities to be verified, and calculates the maximum monthly usage by reflecting the energy efficiency rating and standby power saving authentication information.

Next, the usage rate is calculated based on the monthly available power consumption information and the monthly maximum usage information.

Subsequently, it may be configured to calculate an appropriate contract power by applying a usage rate to the contract power value.

Then, energy efficiency information and standby power reduction certification information are reflected for the electricity-using facilities to be verified, and the monthly maximum usage is predicted for . In the case of the predicted maximum demand power, in calculating the monthly usage time for each facility, the average time of the original usage time secured by the same facility provided or collected and stored by the electricity usage facility information providing computer 5000 can be extracted and applied. have.
