Method for controlling a device

The present invention relates to a control method of a device that can save electricity costs and can efficiently use electric power.

Currently, power grids for electrical appliances such as electrical appliances used in homes or office equipment used in offices are generally supplied in the order of power plants, transmission lines, and wiring lines.

The power grid has the characteristics of a central power source, not a distributed power source, and further has a radial structure that spreads from the center to the periphery, and is characterized by being a supplier center in one direction rather than a consumer center.

The technology base is also analogue or electromechanical. However, the above-described electric power grid was not able to know the price information on the power used in real time, but was limited only through the power exchange. In addition, since the price system is actually a fixed price system, there is a problem that incentives such as incentives to consumers through price changes cannot be used.

In order to solve these problems and improve the energy efficiency, research on the next generation power grid, a so-called "Smart Grid" (Intelligent Power Grid), is being actively conducted. The intelligent power grid refers to the next generation power system and its management system, which are realized through the convergence and complex of modern power technology and information and communication technology.

The calculating of the moving average may include calculating a moving average value of power information of each pre-stored time interval and power information of the recognized current time interval; And recognizing the calculated moving average value as reference information of a subsequent time interval.

In the calculating of the moving average value, the average value may be calculated by multiplying first and second weight values proportional to importance with power information of each pre-stored time period and power information of the recognized current time period.

In addition, the sum of the first and second weight values may be one.

In addition, the reference information may be directly set by a user or provided from a power provider.

In addition, the reference information may be derived through a microcomputer for controlling the driving of the device.

In addition, when the reference information is decreasing and the current time interval is included in the off peak time interval, the device may be driven.

In addition, when the reference information is increasing and a subsequent time interval is included in the off-peak time interval, the device can be driven.

In addition, when the reference information is increasing, the current time interval is included in the off-peak time interval, and the subsequent time interval is included in the on-peak time interval, the device may be driven only in the current time interval.

Referring to FIG. 6, the method of controlling a device according to an exemplary embodiment of the present disclosure may include: (a) recognizing at least one or more power information including an electric charge for each time interval divided into predetermined time intervals (S100). And (b) deriving reference information for each time interval from the recognized power information (S101) and (c) recognizing a trend of reference information during a predetermined time interval (S102) and (d) And determining whether to drive the device according to the trend of the reference information (S103).

In addition, the step of processing the power information may be processed by the user, or may be processed by the power supplier, may be calculated in the microcomputer for controlling the driving of the device, may be calculated in the above-described energy management device.

Referring to FIG. 7, in the intelligent power grid according to the present invention, for example, an electric charge may be changed at a specific day, a specific week, or a specific month, and in particular, the electric charge may be changed according to a specific time on a specific day. For example, in an On Peak Time section in which power consumption is high, an electric charge is set higher than in an Off Peak Time section in which power consumption is relatively low.

In addition, under the intelligent power grid, the power provider may supply the user with electricity rate information for each time interval divided by a predetermined time interval.

Here, the electricity rate information may be known only in the form of schedule information that can be known in advance to the electricity rate information after the time interval including the current time or the electricity rate information of the time interval including the current time, and the electricity rate information of the time interval thereafter Can be classified into a form of real-time information that can be known only in the corresponding time interval, the former is easy to predict because the electricity price information of the next section from the current time in advance, the latter is easy to forecast The difference is that it is difficult to predict because it is unknown.

For example, the electricity rate information (schedule information format) for each section divided into a predetermined time interval that follows, the power bill information for 24 hours after 12 noon day or 12 o'clock every day for 1 hour Alternatively, it may be provided by being divided into a time period of 30 minutes.

In detail, the user may check the power rate for 24 hours in advance through the energy management device. On the other hand, the electric charge information for each section divided into a predetermined time interval in real time means, for example, to continuously receive the electric charge information for the next 5 or 30 minutes at intervals of 5 or 30 minutes, for example. do. Therefore, the user can know the electricity rate information for up to 5 minutes or 30 minutes in the future, it is difficult to know more electricity rate information.

As described above, under the intelligent power grid, bi-directional communication between the power supplier and the demand source is possible, and the power supplier can monitor the power usage of the demand source in real time and flexibly set an electricity rate thereafter. Can be received in real time to postpone the start of the appliance or stop the use of the appliance in operation, thereby enabling the customer to save on electricity bills and allowing the power supplier to distribute power efficiently. .

Under this intelligent power grid, it is desirable for the user or the customer to reduce the running time of the electrical appliance in the on-peak time interval in order to save the electricity bill.

Referring to FIG. 7, in more detail, the real time fee type may be newly set by the power provider in a subsequent time interval at a predetermined time interval and transmitted to the demand destination in real time. For example, if the power provider transmits at 5 minute intervals and the first time T_1 is 9 am, the second time T_2 is 9: 5 am, and then each time T_3 to T_6 and T_K. To T_K + 2) are increased by 5 minutes from the previous time.

Each time included between the first time and the second time may be referred to as a first section ΔT1, and the electric charge at each time within the first section ΔT_1 is the same. Similarly, each time included between the K-th (K> 1) time and the K-th time may be referred to as the K-th period, and the electric charge at each time in the K-th period ΔT_K is the same.

In the real-time rate form, when the time for driving the device (ON) belongs to the K-th time period ΔT_K, the user may recognize the electric charge of the K-th time period, but K + 1 which is a subsequent time period. The electric charge of the time interval ΔT_K + 1 is unknown.

A control method of a device according to an embodiment of the present invention is to derive reference information for each time interval from the recognized power information in order to predict power information (for example, electric charge) of the subsequent time interval as described above. Steps. For example, the reference information represents a predicted value of an electric charge in a subsequent time interval.

The deriving of the reference information may be derived by selecting at least one or more power information of a corresponding time interval of a specific day, a specific week, or a specific month.

For example, the reference information of the K + 1 time period ΔT_K + 1, which is a subsequent time interval, is the electric charge of the K + 1 time interval ΔT_K + 1 of a specific day (for example, yesterday). It may be determined, or may be determined by the electric charge of the K + 1th time interval ΔT_K + 1 of a specific week or a specific month.

In addition, the deriving of the reference information may be derived by selecting a plurality of power information of a corresponding time interval of a specific day, a specific week, or a specific month, and calculating an average value of two or more selected power information.

For example, the average value of the electric charges of the K + 1 time period ΔT_K + 1 for a certain period (5 days or 7 days) may be calculated and adopted as reference information.

In addition, the deriving of the reference information may be derived by calculating power information of each corresponding section for a specific number of days as a moving average.

For example, in the case of adopting the moving average value of 5 days as the reference information, if the reference information is derived from the electricity rates of the K + 1 hour interval (ΔT_K + 1) for the last 5 days, and when one day has elapsed, The moving average may be calculated by including the electric charge of the K + 1 hour period ΔT_K + 1 of the previous day, except for the electric charge of the K + 1 hour interval ΔT_K + 1 of the oldest day.

The calculating of the moving average may include calculating a moving average value of power information of each pre-stored time interval and power information of the recognized current time interval; And recognizing the calculated moving average value as reference information of a subsequent time interval.

In the calculating of the moving average value, the average value may be calculated by multiplying first and second weight values proportional to importance with power information of each pre-stored time period and power information of the recognized current time period.

In addition, the sum of the first and second weight values may be one.

For example, referring to FIG. 10, FIG. 10 (b) shows a table of electricity rates for the current time interval (ie, today) for which the device is to be driven, and FIG. 10 (a) shows the previous time interval (ie, , Electricity rates for yesterday).

Referring to FIG. 10B, when the current time is 00:15, it is possible to recognize that the electric charge is 1000 won, but the electric charge after 00:30 cannot be recognized.

Therefore, the electric charges after 00:30 are required to be predicted. At this time, with reference to FIG. 10 (a), the electric charges of the previous time interval (00:30 ~ 01:00, B) are recognized at 1100 won. You can estimate the electricity bill after 00:30 of the time interval. That is, after multiplying the 1000 won by the first weight value, multiplying the 1100 won by the second weight value, it can be averaged and predicted as an electric charge for a time interval after 00:30. In this case, the sum of the first weight value and the second weight value may be 1, and when the first weight value is 0.5, an electric charge after 00:30 of the current time interval may be predicted as 1105 won (B ′). This weight may be determined by the user or provided by the power provider.

In addition, the reference information may be directly set by the user or provided from a power provider, and may be derived through a microcomputer for controlling the driving of the device.

Referring to FIG. 8, all current reference rates may be predicted using previous electricity rates. The above-described various averages may be used to predict power information of the current A 'time interval from power information of the previous A time interval through several update processes.

Further, in step (b), reference information of the current and at least one subsequent time interval may be derived, reference information of the current and at least one previous time interval may be derived, and thus the electric charges of all time zones may be derived. If all are predicted, this can be used similarly to schedule type power information.

8 and 9, in a method of controlling a device according to an exemplary embodiment of the present invention, an on-peak time interval in which reference information is a predetermined average and an on-peak time interval in which the reference information exceeds a predetermined average value is less than or equal to an off-peak time interval. It may further comprise the step of recognizing. The average value may include an average of power information of a specific day, a specific week, or a specific month.

The recognizing of the on peak time period and the off peak time period may be performed by comparing the power information provided to the device with the reference information set in the device, or the on peak time provided from the outside of the device. It can be recognized by the information of the interval and the off-peak time interval.

On the other hand, the control method of a device according to an embodiment of the present invention includes the step of recognizing the trend of the reference information for a predetermined time interval.

That is, when the reference information for each time interval is derived from the recognized power information, the trend of the reference information for the subsequent time interval after driving the device is recognized, and it is determined whether to drive the device according to the trend of the reference information. do.

For example, as a result of comparing the average value with the reference information, even if the current time interval corresponds to the off-peak time interval, if the reference information corresponds to an increasing trend, it is predicted that the subsequent time interval corresponds to the on-peak interval. The device may not be driven.

In addition, when the reference information is decreasing and the current time interval is included in the off peak time interval, the device may be driven.

In addition, when the reference information is increasing and a subsequent time interval is included in the off-peak time interval, the device can be driven.

In addition, when the reference information is increasing, the current time interval is included in the off-peak time interval, and the subsequent time interval is included in the on-peak time interval, the device may be driven only in the current time interval.

In addition, when reference information is increasing and a subsequent time interval is included in the on-peak time interval, the device may not be driven.

The determining of whether the device is driven may be automatically performed by a user input or a microcomputer, and may further include displaying the power information and reference information to the outside so that a user can recognize the device. have.

On the other hand, in the step of determining whether to drive the device, it is possible to drive only the function of some of the power consumption unit of at least two or more power consumption unit included in the device, or may not drive the function of some power consumption unit.
