Description

Electricity savings analysis device and electricity bill savings analysis method

The present invention relates to an apparatus for analyzing electricity bill savings and a method for analyzing electricity bill savings, and more particularly, by analyzing a power consumption pattern in which power is consumed for each outlet (electronic device) in a home, adding an electronic device in each home and The present invention relates to an electricity rate reduction analysis apparatus and an electricity rate reduction analysis method for reflecting a change in an analyzed power consumption pattern, comparing and calculating the expected electricity cost of each household, and notifying each household of this information.

The Smart Grid is a vision that can optimize energy efficiency by converting the existing one-way power grid, which consists of power generation-transmission and distribution-sales, into a system in which power providers and consumers exchange real-time information in both directions. present. According to the smart grid construction, electricity consumers can use low electricity rates by checking electricity rates by time, away from unilateral electricity usage rate notification there is.

As a part of the smart grid, Korea Electric Power Corporation (KEPCO) is actively developing an In Home Display (IHD) distribution business, which provides not only energy consumption but also various information necessary for life safety It is a device that made it possible.

However, there may be a difference between the electricity rate displayed on the IHD and the electricity bill actually charged. In particular, in the case of apartment houses, the electricity supply contract method is divided into a single contract method or a comprehensive contract method, other than the standard for residential (low voltage) electricity rates, and there may exist a method for calculating the electricity rate of the apartment house itself, and there is a common facility such as an elevator. Since the electricity rate for electricity needs to be additionally considered, there may be a large error between the displayed electricity rate and the actual billed electricity rate.

In order to solve this problem, it is necessary to compensate for the displayed electricity rate in consideration of all factors that may cause rate error. In addition, in the current electricity rate system, where a step-by-step progressive system is applied, there is a discontinuous progressive phenomenon in which electricity usage rates increase significantly from the starting point of the electricity usage when the unit price changes. You need an electricity bill display device that can display it.

As a part of solving this problem, registered patent No. 10-1163561 (registration date: July 02, 2012), which is cited as a prior document in the present application, calculates electricity rates by acquiring electricity consumption of consumers in real time. In addition, a method is proposed to reduce the error between the actual billed electricity rate and the displayed electricity rate by correcting the calculated electricity rate.

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

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

Referring to FIG. 2 , in the technology disclosed in the prior literature, the electricity rate standard is received, the current electricity consumption information that is electricity usage information up to this month of the consumer is acquired (S310), the current electricity rate is calculated (S320), and the past month Calculates a correction coefficient from the electricity rate calculation information of the last month and the actual electricity bill information of the previous month (S330), corrects the current electricity rate based on the calculated correction coefficient to calculate the expected electricity rate (S340), and the estimated electricity rate The real-time electricity rate is calculated by using the linear proportional relationship between the calculation time and the total time of the month to calculate the current month's expected electricity rate, which is the current month's expected electricity rate (S350).

On the other hand, referring to FIG. 4 , in the technology disclosed in the prior literature, the current electricity usage, which is the electricity usage information up to this month, of the consumer is acquired (S410), and the expected current electricity consumption of the consumer is calculated based on the current electricity consumption, (S420), after calculating the current monthly electricity rate of the consumer based on the electricity rate standard and the current monthly electricity consumption (S430), corrected based on the electricity rate for the past month calculated by the electricity rate calculation unit and the actual electricity rate for the past month It also discloses a method of calculating a coefficient (S440), and calculating an estimated electricity charge for the current month based on the calculated current electricity rate and a correction coefficient (S450).

In both of these methods, there is only a change in the order, and the correction coefficient is calculated from the deviation between the electricity billing information calculated for the previous month and the actual electricity billing information, and the correction coefficient is used to compare the actual electricity bill generated when the electricity bill is calculated for the current month. The point lies in reducing the deviation.

However, there is no confirmation that the deviation generated between the electricity rate calculated in the previous month and the electricity bill actually charged will also occur in the current month. In other words, even if the amount of deviation or the deviation ratio (correction coefficient) is applied to the current month without knowing the cause of the deviation that occurred in the previous month, if the unknown factor is not applied to the current month, the correction coefficient is the opposite of accurate rate calculation. It may act as a cause of increased deviation.

In addition, in the prior art, the expected electricity rate for the current month, which is the expected electricity rate for the month, is calculated using a linear proportional relationship between the time at the time of calculating the expected electricity rate and the total time of the current month. can't see doing it In other words, depending on the situation of each household, there may be variations in device usage from month to month, such as it was hot last month and used a lot of air conditioner, but this month it got cooler and the air conditioner usage decreased. However, this year, due to severe typhoons and rainy seasons, there are relatively few hot days, so there may be variations in device use by year, such as small air conditioner usage. There is bound to be a large error in calculating the fee.

In addition, in the conventional method, since it is possible to determine the cause of the occurrence of a 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 point to know what to do to reduce the electricity bill.

In addition, since Korea Electric Power Corporation is currently applying the progressive system, the basic rate and the unit rate are set differently for each section of power consumption. Although this range of change may be large, from the consumer's point of view, information on how to use convenience devices reasonably, that is, information on which electronic devices to use, which electronic devices to use, and how to use electronic devices for their own convenience by reducing the use of them was difficult to provide. As a result, there is a problem in that even after purchasing an electronic device for living convenience, it is not fully utilized.

In addition, in the prior art, only the estimated electricity bill is calculated using only the total amount of electricity in each household, and the power consumption for each individual device or individual outlet is not calculated. The loss of power that users do not use for their own convenience is not understood, so the waste of electricity bills cannot be reduced.

Thus, it is determined whether a preset difference (eg, 10%) or more occurs ( S120 ).

If there is no abnormality in step S120 , the system controller 140 proceeds to step S170 to be described later to calculate the expected monthly electricity rate for each candidate rate plan, which will be described in more detail in step S170 .

Meanwhile, in step S120, by comparing the power consumption pattern information for each unit time received from the power consumption pattern analysis unit 130 for each of the plurality of outlets 320 and the power consumption pattern for the same period of the previous year stored in the database 120 in advance, , when more than a preset difference (eg, 10%) occurs, the system control unit 140 sends an inquiry message to the user terminal 400 through self-discovery, such as home network search, or the communication unit 150, or on an app or program It is checked whether the new electronic device 330 has been added to the customer 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 through the model name of the changed electronic device 330 found through self-discovery in the home network or through an application or program installed on the user terminal 400 , the corresponding Select from a list provided on the application or program, or add the electronic device 330 newly added according to the model name manually input by the user to the electronic device information stored in the database 120 and register (S140).

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

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

Meanwhile, in step S130, if a new electronic device is not added, a method such as self-discovery such as home network search, sending an inquiry message to the user terminal 400 through the communication unit 150, or generating a push message in an app or program , it is checked whether the existing electronic device 330 has been changed to a different product (a different product with 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 in the home network, or an application installed on the user terminal 400 or Through the program, the electronic device 330 is selected from a list provided on the corresponding application or program, or the electronic device 330 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 downloads product information to the electronic device information stored in the database 120 , for example, the new electronic device 330 . ) for the model name, use and power consumption are stored (S155).

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

Then, the system control unit 140, the power consumption pattern calculated by the power consumption pattern analysis unit 130 in step S110, the previous power consumption pattern information stored in the database 120 or the power consumption pattern found in steps S160 and S165 By comparing the information for each of the plurality of outlets 320, the monthly estimated power consumption for each outlet for each of the outlets 320 is calculated, and the total monthly expected power consumption is calculated by the sum of the monthly expected power consumption for each outlet, Based on the total monthly expected electricity consumption and the billing reference charge information stored in the database 120, a monthly estimated electricity charge for each candidate rate plan is calculated (S170). That is, by applying the total monthly electricity consumption calculated to the billing standards of each of the rate plans (hereinafter also referred to as candidate rate plans) that can be selected by each household, including the rate plan for each additional discount provided by the power company 200, each Calculate the estimated monthly electricity bill for each rate plan.

Thereafter, the system control unit 140 displays a comparison table of the expected 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 the monthly expected electricity rates calculated for each rate plan to the communication terminal 400 in the form of a text message or data in step S170 and provide it to the user.

Meanwhile, when there is no electronic device 330 changed in step S135 , the system controller 140 , that is, the power consumption pattern calculated by the power consumption pattern analyzer 130 and the previous power consumption pattern information stored in the database 120 . is compared for each of the outlets 320 , and there is an error over a preset range between 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 , In the absence of the device 330 or the changed electronic device 330, an abnormal power consumption alert message including information on the electronic device previously registered in the outlet and the outlet in which the error occurred 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 use, period, and time, and even the variable outlet 320 to which the electronic device is connected/disconnected has a constant consumption for each outlet 320 . Even though there is a power pattern, a significant deviation in the power consumption pattern on the day of the period is not used by actual users, such as, for example, that the air conditioner operates even when no one is 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 high, and if it is not, or if the error persists, you may suspect a short circuit in the relevant section. Accordingly, an abnormal evening consumption warning message is transmitted to the user terminal 400 through the communication unit 150 , including information on the corresponding outlet 320 and the electronic device 330 connected thereto.
