Electricity rate reduction analysis device and electricity rate reduction analysis method {APPARATUS AND METHOD FOR ANALYZING IT TO REDUCE ELECTRICITY BILLS}

The present invention relates to an electric charge reduction analysis device and an electric charge reduction analysis method, and more specifically, to analyze a power consumption pattern in which power is consumed for each outlet (electronic device) in a home, add electronic devices in each home, and An electric bill reduction analysis device and electric bill reduction analysis method for comparing and calculating expected electric bills of each household by reflecting a change in the analyzed power consumption pattern, and notifying each household of the estimated electricity bill.

The establishment of the Smart Grid is a vision that can optimize energy efficiency by converting the existing one-way power grid, which was performed in the stages of generation-transmission and distribution-sale, into a system in which electricity operators and consumers exchange real-time information in both directions. present. With the establishment of the smart grid, power consumers can use low-cost electricity rates by checking electricity rates by hour, away from one-sided notification of power usage rates, and can further generate profits by reselling surplus power to the power system using distributed power sources. have.

As part of the smart grid, Korea Electric Power Corporation (KEPCO) is actively developing an in-home display (IHD) distribution project. IHD provides not only energy consumption but also various information necessary for life safety. It is a device that allows you to

However, a difference may occur between the electricity rate displayed on the IHD and the actual electricity rate charged. In particular, in the case of multi-unit dwellings, the electricity supply contract method is divided into a single contract method or a comprehensive contract method in addition to the residential (low-voltage) electricity rate standard, and the multi-unit dwelling may have its own electricity rate calculation method, and common facilities such as elevators Since an electric charge and the like must be additionally considered, an error between the displayed electric charge and the actually charged electric charge may be large.

In order to solve this problem, it is necessary to compensate for the displayed electricity rate by considering all factors that can cause rate errors. It can be said to be close, and in the current electricity rate system, where the step-by-step progressive system is applied, there is a discontinuous progressive phenomenon in which electricity usage rates increase significantly starting from the power consumption at which the unit price of electricity rates changes. You need an electricity bill display device that can be displayed.

As part of solving these problems, Patent Registration No. 10-1163561 (Registration Date: July 2, 2012), which is cited as prior literature in this application, acquires electricity consumption of consumers in real time to calculate electricity rates and correcting the calculated electricity rate to reduce the difference between the actual electricity rate and the displayed electricity rate.

In the network configuration (see FIG. 1) centered on the real-time electricity rate display device 100 according to the prior art, a method of calculating real-time electricity rates is described with reference to FIGS. 2 and 3 as follows.

1 is a network configuration diagram centered on an electric charge display device according to the prior art, FIG. 2 is a flowchart of a real-time electric charge calculation method according to an embodiment of the prior art, and FIG. 3 is a flow chart of another embodiment of the prior art. It is a flow chart of the real-time electricity rate calculation method according to

Referring to FIG. 2, in the technology disclosed in the prior art, an electricity rate standard is received, current electricity consumption information, which is electricity consumption information of the consumer until this month, is acquired (S310), the current electricity rate is calculated (S320), and the past month A correction coefficient is calculated from the electricity rate calculation information and the actual electricity rate information of the last month (S330), and the current electricity rate is corrected based on the calculated correction coefficient to calculate the expected electricity rate (S340). By using a linear proportional relationship between the time at the time of calculation and the total time of this month, the expected electricity price for this month, which is the expected electricity price for this month, is calculated (S350), real-time electricity price is calculated.

On the other hand, referring to FIG. 4, in the technology disclosed in prior literature, current electricity consumption, which is information on electricity consumption up to the present month of the consumer, is obtained (S410), and the expected electricity consumption of the consumer for the current month is calculated based on the current electricity consumption, (S420), after calculating the electricity price of the consumer for the current month based on the electricity price standard and the electricity usage for the current month (S430), correction is made based on the electricity price of the past month calculated by the electricity price calculation unit and the actual electricity price of the past month A method of calculating a coefficient (S440) and calculating an expected electricity price for the current month based on the calculated electricity price for the current month and a correction coefficient (S450) is also disclosed.

In both of these methods, there is only a change in the order, and a correction coefficient is calculated from the difference between the previous month's calculated rate information and the actual power billing information, and the correction coefficient is used to calculate the current month's electricity rate. The point is to reduce the variance.

However, there is no confirmation that the deviation generated between the electricity rate calculated in the previous month and the electricity rate actually charged also occurs in the current month. That is, even if the cause of the deviation occurred in the previous month is not known and the deviation amount or deviation ratio (correction coefficient) is applied to the current month, if the unknown factor is not applied to the current month, the correction coefficient is rather inverse to accurate rate calculation. It may act as a cause of an increase in the variance.

In addition, in the prior art, the estimated electric charge for the current month, which is the electric charge expected for this month, is calculated using a linear proportional relationship between the time at the time of calculating the estimated electric charge and the total time of this month, but the power consumption between the previous month and the current month is necessarily proportional. can't see doing it In other words, depending on the situation of each household, there may be variations in the use of devices by month, such as last month when it was hot and the air conditioner used a lot, but this month it became cool and the air conditioner use decreased. However, this year, there may be deviations in device use by year, such as relatively hot days due to severe typhoons and rainy season, so air conditioner usage was small, etc. There is bound to be a large margin of error in calculating rates.

In addition, in the conventional method, since it is possible to determine the cause of the deviation in the electricity calculation rate between the previous month and the current month, there is a problem in that the user cannot find an improvement in what to do to reduce the electricity rate.

In addition, since Korea Electric Power Corporation is currently applying the progressive system, and since the basic rate and unit rate are set differently for each section of electricity consumption, when there is a change in power consumption in each household, the rate on the boundary of the section to which the progressive system is applied Although this range of change may increase, from the consumer's point of view, information on rational use of convenience devices, that is, information on which electronic devices to use and which electronic devices to reduce the use of electronic devices to suit their convenience. was difficult to obtain. As a result, there is a problem in that even after purchasing an electronic device for the convenience of life, it is not fully utilized.

In addition, in the prior art, only the total amount of electricity in each home is used to calculate the expected electricity rate, and the power consumption for each individual device or individual outlet is not calculated, so that unused devices are operating or a short circuit occurs. Since the user does not grasp power loss that is not used for convenience in his or her own life, the waste of electric charges for this cannot be reduced.

The system controller 140 compares the power consumption pattern information per unit time received from the power consumption pattern analysis unit 130 for each of the plurality of outlets 320 with the power consumption pattern per unit time for the same period of the previous year previously stored in the database 120. Thus, it is determined whether a predetermined difference (eg, 10%) or more occurs (S120).

If there is no abnormality in step S120, the system control unit 140 proceeds to step S170 to be described later and calculates an expected monthly electric charge for each candidate rate plan, which will be described in detail in step S170.

Meanwhile, in step S120, the power consumption pattern information per unit time received from the power consumption pattern analysis unit 130 for each of the plurality of outlets 320 is compared with the power consumption pattern per unit time during the same period of the previous year previously stored in the database 120. , If a preset difference (eg, 10%) or more occurs, the system control unit 140 sends an inquiry message to the user terminal 400 through self-search or communication unit 150 such as home network search, or on an app or program. It is confirmed whether a new electronic device 330 is added to the number of customers by a method such as generating a push message (S130).

In step S130, if a new electronic device is added, the system control unit 140 determines the corresponding model name of the changed electronic device 330 found through self-discovery within the home network or through an application or program installed on the user terminal 400. The electronic device 330 selected from the list provided on the application or program or newly added by the model name manually input by the user is added to the electronic device information stored in the database 120 and registered (S140).

Thereafter, the system controller 140 downloads product information from the homepage of the corresponding electronic device 330 through the registered model name, and includes the downloaded product information in the electronic device information stored in the database 120, for example, the new electronic device 330 ) Stores usage and power consumption for the model name (S150).

In addition, the system controller 140 searches for an average consumption pattern from the corresponding homepage together with the operation in step S150 (S160). In another embodiment of the present invention, this step may be omitted, the accumulated power consumption pattern may be stored for a certain period of time, and the accumulated and stored power consumption pattern may be used.

On the other hand, in step S130, if a new electronic device is not added, a method such as self-searching such as home network search, sending an inquiry message to the user terminal 400 through the communication unit 150, or generating a push message on an app or program , it is confirmed whether the existing electronic device 330 has been changed to another product (another product having a different model name) (S135).

In step S135, if there is an electronic device 330 that has been changed to another product, the system controller 140 determines the model name of the changed electronic device 330 found through self-discovery within the home network or an application installed on the user terminal 400 or Through the program, the electronic device 330 selected from the list provided on the corresponding application or program or changed by the model name manually input by the user is added to the electronic device information stored in the database 120 and registered (S145).

Thereafter, the system controller 140 downloads product information from the homepage of the corresponding electronic device 330 through the registered model name, and includes the downloaded product information in the electronic device information stored in the database 120, for example, the new electronic device 330 ) Stores usage and power consumption for the model name (S155).

In addition, the system controller 140 searches for information on the electronic device 330 before the change from the database 120 (S165). That is, since the changed electronic device 330 has the same purpose as the electronic device 330 before the change, for example, because an existing air conditioner is changed to another new air conditioner or an existing refrigerator is changed to another new refrigerator, The power consumption is changed, but the power consumption pattern is the same. That is, when the changed power consumption of the electronic device is applied to the power consumption pattern of the existing electronic device 330, the changed power consumption pattern of the electronic device 330 can be used.

Thereafter, the system controller 140 determines the power consumption pattern calculated by the power consumption pattern analyzer 130 in step S110 and the previous power consumption pattern information stored in the database 120 or the power consumption pattern retrieved in steps S160 and S165. Comparing the information for each of the plurality of outlets 320, calculating the expected monthly power consumption per outlet for each outlet 320, and calculating the total expected monthly power consumption by the sum of the expected monthly power consumption per outlet, Based on the total expected monthly power consumption and the billing standard rate information stored in the database 120, the expected monthly electricity rate for each selected candidate rate plan is calculated (S170). That is, by applying the total estimated monthly power consumption calculated to the billing standard for each rate plan (hereinafter referred to as a candidate rate plan) that each household can select, including the rate plan for each additional discount provided by the power supply company 200, Calculate the expected monthly electricity cost for each tariff plan.

Thereafter, the system controller 140 displays a comparison table of estimated monthly electricity rates calculated for each rate plan in step S170 on a display not shown (S180). In another embodiment of the present invention, the system control unit 140 may transmit a comparison table of estimated monthly electricity rates calculated for each rate plan in step S170 to the communication terminal 400 in the form of a text message or data and provide it to the user.

On the other hand, the system control unit 140, when there is no electronic device 330 changed in step S135, that is, the power consumption pattern calculated by the power consumption pattern analysis unit 130 and the previous power consumption pattern information stored in the database 120 Compared to each of the outlets 320, there is an error of more than a predetermined range between the power consumption pattern calculated by the power consumption pattern analyzer 130 and the previous power consumption pattern information stored in the database 120, and the newly added electronic If there is no device 330 or the changed electronic device 330, an abnormal power consumption warning message including information about the outlet where the error occurred and the electronic device pre-registered in the outlet is sent to the user through the communication unit 150. (S190). That is, the electronic device 330 connected to each outlet 320 has a constant usage pattern for each purpose, period, and time, and even the variable outlet 320 where the electronic device is connected/disconnected consumes a constant for each outlet 320. Even though there is a power pattern, the power consumption pattern on the day of the corresponding period is significantly different, for example, the air conditioner operates even when there are no people indoors, or the electric blanket operates even when it is not bedtime. There is a high possibility that an electronic device that does not operate is likely to operate, and if it is not, or if the error persists, a short circuit may be suspected in the corresponding section. Accordingly, an abnormal evening consumption warning message including information about the corresponding outlet 320 and the electronic device 330 connected thereto is sent to the user terminal 400 through the communication unit 150 .

According to the method of analyzing the electricity cost reduction method described above, the power usage pattern of each electronic device used in the home is changed, the unit electricity rate of the electricity supply company is changed, the progressive section is changed according to the amount used, and the periodic discount or premium is applied. Even if billing standards, such as discounts or premiums for each time slot, are changed, an estimated electricity rate for each electricity rate plan can be calculated and information for selecting an optimal electricity rate plan can be provided to the user.

In addition, according to the method of analyzing the electricity cost reduction method described above, the power consumption pattern of each outlet (by electronic device) in the home is analyzed by unit time, and the usage characteristics of each electronic device by purpose, seasonal usage characteristics of each electronic device, The effect of enabling users to accurately recognize the impact of each electronic device on the electricity bill and to utilize the electronic device for their own purpose by accurately predicting the impact on the electricity bill for the current month according to the usage characteristics of the electronic device by time, etc. there is
