Hereinafter, various embodiments of the present application will be described. For reference, the embodiments provided in the present application are provided as an example for describing the technical idea of the present application, and the technical scope of the present invention is not limited to the provided embodiments.

1 is a diagram illustrating power usage utilizing the smart grid power information network 10 according to an embodiment of the present application. The smart grid power information network 10 is connected to a power supply organization 11 that produces and supplies power and a power management organization 12 that manages power generation and supply, and a power consumption organization 13 that consumes power. May be called an 'acceptor'). In particular, FIG. 1 illustrates one of various power consumption organizations 13 connected to the smart grid power information network 10. For example, in a general home environment, a power network 20 (hereinafter also referred to as an 'internal network') is shown. It is shown in the center. In the internal network 20, various electronic devices 21 to 26 are connected to a communication network. For example, the air conditioner 22, the refrigerator 23, the TV 24, the washing machine 25, And a portable mobile device 26 and the like, and a power control device 21 (also referred to as a “smart server”) that controls and manages power use of the electronic devices may exist separately.

In this regard, the present application, in particular, is connected to the smart grid power information network 10, the configuration of the power control device 21 for controlling the power use of electronic devices in the internal network 20 and the power control method using the same It is about. In this regard, the present application is intended to describe the power control device 21 as an example of a separate product for convenience of description, but the power control device 21 is required as an independent product to implement the present invention. In some embodiments, it is possible that any one of the specific electronic devices inside the internal network replaces the electronic device. For example, it is also possible to include the configuration of the power control device and control method to be described in the present application inside the TV 24 or the portable mobile device 26.

The customer 13 is based on the power consumption of the electronic devices (21 ~ 26) connected to the internal network of the power rate management institution (for example, the power supply agency 11 or power management agency 12 of the You may pay for the electricity you used for either) or another organization.

2 illustrates various examples of power plans, applicable to embodiments of the present application. In particular, the plan # 1 (31) shows an example of a plan generally used in the prior art composed of the basic charge item 41 and the power charge item 42. The power rate item 42 may be, for example, a progressive agent applied, which means a method in which a higher unit price power rate is applied as the amount of power usage increases.

In connection with the present application, new plans such as Plan # 2 (32) and Plan # 3 (33) are proposed. The rate plan # 2 32 and the rate plan # 3 33 further include a power saving period discount rate 43 in addition to the basic rate item 41 and the power rate item 42 of the rate plan # 1. The power saving period discount rate item 43 may be, for example, a certain portion (eg, 20%, or 30 to 40% discount) of the electricity bill as an incentive for achieving the power saving target in the specified power saving period. It is an item. In this regard, the 'power saving section' is a section set by the above-described power bill management institution. For example, the electric power demand section, the high charging section or the emergency power section may correspond to this. In other words, the power saving period is a time period in which a large amount of power consumption is expected in the consumer, and this may be a period in which power consumption is required to save power or a section in which other emergency power is used.

In relation to this, instead of applying the unit price of the progressive power rate item 42 between plan # 2 32 and plan # 3 33 differently, depending on the existence of a premium rate item 44 when the power saving period is not met. Can be distinguished. For example, plan # 2 (32) refers to a plan that is composed of a power plan item 42 of the same progressive plan as plan # 1 (31), while a premium rate is charged as a penalty when the power saving target is not met. . On the other hand, the plan # 3 (33) is a plan that is higher than the plan # 1 (31) in the power rate item 42 of the progressive plan, while a plan that does not impose a premium rate as a penalty when the power saving target is not met. it means. Instead, plan # 3 33 may apply a higher discount rate 43 than plan # 2 32.

Power plan (31, 32, 33) described as an example in Figure 2 is presented for convenience of explanation, it will be apparent that there are more various types of plan may exist. However, the embodiment of the present application may be referred to as a method that is more in line with the rate system in which there is an incentive for achieving the power saving target in the power saving period.

3 illustrates an example of a power rate management method and a power rate differential management method according to an embodiment of the present application. In relation to this, the process of Figure 3 is shown centering around the communication between the server 51 and the consumer smart server 52 of the power bill management authority, which is presented as an example for convenience of description, various other examples may exist . For example, the consumer smart server 52 may be replaced with a mobile device or a smart TV.

The process of FIG. 3 begins with power plan selection. As described above with reference to FIG. 2, the power rate management agency provides a plurality of plans (S101), and the customer may select any one of these plans (S102). However, the steps S101 and S102 are not necessarily performed only in an on-line state through a network, but may be set in advance in an off-line state. If the steps (S101, S102) proceeds in an on-line state using the customer smart server 52, the user by providing a graphical user interface (GUI) for the power plan selection by the user It is desirable to be able to choose a plan.

Particularly, in the embodiment of the present application, among the plurality of power plans of FIG. 2, the customer smart server 52 receives a plan (for example, FIG. 2, plan # 2, plan # 3) in which an incentive is granted to a power saving period. The explanation will focus on the selected case. Hereinafter, such a plan will be referred to as a 'sleep plan' for convenience.

In relation to this, when a user (eg, the person who charges the electricity bill) selects the power saving plan, the power bill management agency notifies the power saving section and the power saving target amount corresponding to the selected power saving plan.

For example, when the user selects the rate plan # 2 of FIG. 2 as the power saving rate plan, the power rate management authority may select at least one of the charge rate periods existing within the corresponding charge period before the corresponding charge section (also referred to as the 'all section') begins. You will be notified by specifying one or more power saving intervals. In detail, for example, if the billing section (or the entire section) is billed monthly (monthly), it will be applicable from the beginning of the month to the end of the month, the power saving period is the power saving within the billing section As the required time zone, it may be determined as, for example, '1 pm to 4 pm daily' or '11 am to 3 pm weekdays: Monday to Friday '. That is, the selection of the power saving period is determined by comprehensively considering and predicting the current state of power production and demand in the power rate management agency. Accordingly, the power saving section is determined as at least one discontinuous section within the charging section, and the determined power saving section is notified to the customer in advance before the charging section starts. For reference, for example, the graph of FIG. 9 illustrates a case where n power saving sections are set in the entire charging section.

In addition, the "power saving target" means a power saving target to be achieved in the determined power saving section. For example, the power saving target amount may be set to the same target value for all customers, or may be set to a different target value for each customer. For example, if the customer is a general household, the same power saving target can be given to all consumers based on the average power consumption of the same type of general household customer managed by the power bill management agency (common power saving). Target volume). Alternatively, it is possible to assign different power saving targets to each customer, taking into account the characteristics of individual consumers, taking into account the average power consumption during the previous specific interval (eg, 1 year, June, or March). (Individual power saving target). That is, it is also possible to include the setting of the 'power saving target amount' as one item in various tariffs so that individual consumers can select their own power saving target amount (eg, common power saving target amount or individual power saving target amount).

In addition, the power saving target amount may be set to a different target value according to the kind of inactive (eg, power saving discount rate) and / or penalty (eg, premium rate). For example, when the power saving discount rate is 40%, a larger power saving target may be given than when the power saving discount rate is 20%. Alternatively, if the penalty rate is imposed, it is possible to set a lower power saving target than if the premium rate is not imposed.

As described above, the customer smart server 52 receiving the 'power saving section' and the 'power saving target' in step S103 performs a power control process corresponding thereto (S104). A detailed description of the power control process will be described later with reference to FIGS. 5 to 10.

When performing the power control process by the step S104, and the entire billing section is finished, the consumer smart server 52 is the power consumption management authority for the total 'power consumption' and 'power saving information' used in the billing section; The server 51 is notified (S105). For example, the total 'power consumption' refers to the total amount of power used in the consumer within the billing section regardless of the power saving section, and the 'power saving information' indicates whether the power saving target is achieved within the given power saving section. Means information that can be checked. For example, the power saving achievement information may be replaced with the amount of power used in the power saving period. Even if only the amount of power used in the power saving period is notified, the power rate management institution can check whether the corresponding power saving is achieved by comparing with the power saving target amount already set. In addition, for example, the power saving achievement information may be configured only with information (Yes or Not) for notifying whether the achievement is achieved, the final confirmation of the achievement is possible in the power bill management agency.

In this regard, step S105 may be omitted, depending on the specific power system usage example. For example, if the power rate management agency has a process for checking the total power consumption of each individual customer and the power consumption in the power saving period, there is no need to go through a separate power notification step after the billing section as in step S105. It will be alright.

Even by the step S105 or by another process, the power rate management agency that has confirmed whether the total power consumption and the power saving has been achieved, is determined according to the total power consumption and the power saving at the customer based on the selected price plan of the individual customer. The final power fee for the billing section is determined and notified (S106).

Hereinafter, an embodiment of the present application for performing the power control process (S104) to meet the power saving target, in particular, according to the power billing process as described above is as follows.

First, FIG. 4 exemplarily illustrates a configuration of a power control device (for example, a smart server) according to an embodiment of the present application. In the power control apparatus according to the embodiment of the present application, for example, the reference value setting unit 101, the used power checking unit 102, the comparing unit 103, the communication unit 104, the control unit 105, and the display unit 106. ) And a power rate management unit 107. In this regard, the configuration is shown as a functional block for the convenience of description, in actual implementation it may be possible to exist in a single configuration or to be implemented in a software program. For example, the reference value setting unit 101, the power usage checking unit 102, the comparing unit 103, the control unit 105, and the power rate management unit 107 may be configured as one control function block. . In addition, specific functions in the reference value setting unit 101, the power usage checking unit 102, and the power rate management unit 107 may store and use the corresponding information by using a storage means (eg, a memory). In addition, in certain embodiments of the present application, it will be apparent that some of the components may be additional components that are not necessarily necessary components.

The communication unit 104 is connected to the above-described smart grid power information network 10 is capable of bidirectional communication for receiving power information or transmitting related information. In particular, the communication unit 104 will be connected to the above-described power bill management organization in a network to perform the above-described steps of the communication process of FIG. 3 (eg, S101, S102, S103, S105, S106). In addition, the communication unit 104 may be connected to the internal network 20 to perform bidirectional communication with various electronic devices (eg, 22 to 26 of FIG. 1) that are connected and exist in the internal network 20. In particular, it is responsible for transmitting a power control signal according to the control process of the control unit 105 in the power control device to each of the electronic devices (22 to 26). Therefore, for convenience of description, the communication unit 104 is illustrated as one function block, but as described above, a set of various communication modules (eg, wired, wireless, short-range communication capable modules) that perform a plurality of communication functions. Can be understood in units.

The power bill management unit 107 is a plan selection module 1071 that provides a program including a user interface (UI) for selecting a plan suitable for a user among a plurality of plans, received in step S103 of FIG. A module 1072 for checking the power saving section and the power saving target amount and storing the corresponding value, and a module 1073 for checking the power billing notification received in step S106 of FIG. 3 and determining whether there is an abnormality. In this regard, the information checked by each module in the power bill management unit 107 may be visually displayed on one side of the display unit 106 and provided to the user.

The reference value setting unit 101 sets a reference value for power control and stores the set reference value. First, the reference value setting unit 101 includes a section setting module 1011 for setting the entire billing section and the power saving section in the billing section. Each power saving section in the charging section is determined based on the power saving section information received in step S103 of FIG. 3. In addition, the reference value setting unit 101 includes a module 1012 for setting a power saving target reference value based on the power saving target amount received in step S103 of FIG. 3. The power saving target reference value refers to a maximum cumulative amount of power allowed during the power saving period. For example, the power saving target reference value may be set to a power value converted from the received power saving target amount (eg, power saving target 20%) into power amount. That is, the power saving target reference value corresponds to a basic reference value for performing a power control process in the power saving period, and the controller 105, which will be described later, performs power control to use power within a range not exceeding the set power saving target reference value. Will be performed. Therefore, it is also possible to set the power saving target reference value to a value lower than the power value converted from the power saving target amount (for example, the power saving target 20%) into the power amount, in which case the power control will be further enhanced. In other words, by allowing the user to select the power saving target reference value, it is possible to adjust the intensity of the power control process applied within the customer.

In addition, the reference value setting unit 101 includes a module 1013 for setting a reference value for each power saving period received. The reference value for each power saving period is determined in consideration of the number and interval size of power saving sections within a range not exceeding the above-described total power saving target reference value. In addition, the reference value setting unit 101 includes a module 1014 for setting an instantaneous power reference value for use in power control.

For reference, the power saving period setting and the reference value setting in the graph of FIG. 9 will be described below. That is, FIG. 9 illustrates a virtual power saving period graph in which each power saving period in the billing section is continuously aligned. Specifically, for example, only n power saving sections (power saving section # 1, power saving section # 2, ..., power saving section #n) notified within the entire billing section are extracted and rearranged on a continuous time axis. will be. Therefore, after setting the power saving target reference value applied to the power saving section to 'Max-P', the reference value THS # i is set for each power saving section. The reference value THS # i for each power saving period is a reference value for managing the cumulative power amount used in the power saving period up to the corresponding time point. Therefore, the reference value THS # n of the power saving section #n existing in the last section should be set at least equal to or preferably lower than the final power saving target reference value Max-P.

In addition, the power usage check unit 102 is responsible for checking the power usage state of the electronic devices (eg, FIGS. 1 to 22 to 26) in the internal network 20. In the used power information checking unit 102, a current time check module 1021 for checking whether a current time corresponds to a power saving period within the set billing period, and a start time of the set power saving period (power saving period # of FIG. 9). Power saving section cumulative power check module 1022 to check the cumulative power consumption value in the power saving period from the start time of 1) to the current time point and instantaneous power checking module for checking the instantaneous power value at the current power saving section time (1023).

In addition, the comparison unit 103 performs a comparison between the above-mentioned information in the reference value setting unit 101 and the used power checking unit 102 under the control of the control unit 105.

The control unit 105 controls all the components in the power control device, and determines the 'control mode' for each electronic device in the internal network 20 based on the result of the comparison unit 103 and corresponds thereto. After generating a power control signal to control, and to transmit the power control signal generated by the communication unit 104 for each electronic device. In relation to this, the control mode determined by the controller 105 may be divided into, for example, a normal mode, a primary control mode (for example, a power saving mode), and a secondary control mode (for example, a shutdown mode). Detailed description thereof will be given later.

The display unit 106 is constituted by means in which the user in the power control apparatus is audible and / or visually recognizable. Through the display unit 106, the power control device can provide a variety of information to the user. For example, it is possible to provide a user notification message suitable for a plan selection process, setting a power saving target reference value, and a control mode of the controller 105.

Hereinafter, a power control method according to an embodiment of the present application will be described in detail with reference to FIGS. 5 to 10. 5 to 8 illustrate a flowchart of a power control method according to an embodiment of the present application, and FIGS. 9 to 10 illustrate graphs for explaining the power control method.

Referring to FIG. 5, first, a power plan is selected through the plan selection module 1071 (S201). Thereafter, at least one power saving period (e.g., n total power saving periods) and power saving targets within the charging period related to the selected power plan are received from the aforementioned power bill management authority, and the received power saving period and the power saving target amount are the power rates. The related module 1072 in the management unit 107 confirms and stores (S202).

Thereafter, the above-described section setting module 1011 sets an entire charging section and a power saving section within the charging section (S203). In addition, through the above-described reference

value setting modules

1011, 1012, and 1013 in the reference value setting unit 101, an instantaneous power reference value to be used for power saving target reference value Max-P and power control applied to the entire charging period. (THI) and the set reference value for each power saving period (THS # i, i = 1, 2, ..., n) are set (S204). In this regard, for example, when setting the reference value, the power saving target reference value Max-P is first set in consideration of the received power saving target amount, and the instantaneous power reference value THI and the reference value for each power saving section THS # i are set. May be set in consideration of the set power saving target reference value Max-P.

When setting the reference value is completed by the step S204, it is checked whether the first power saving section (i = 1) is started (S205). In the section in which the power saving section is not started, power control is performed in the normal mode (S206), and when the first power saving section (i = 1) is started, the power control process is operated (S207). A detailed operation of the step S207 will be described later in detail with reference to FIGS. 6 to 8.

The power control in step S207 can be terminated at the end of the power saving section (i = 1), and then is performed again in step S205 in the next power saving section (i = 2). However, if the entire billing period is terminated (S208), it is confirmed whether the power saving target is achieved within the power saving period, and the corresponding information is notified to the power rate management authority (S209).

Hereinafter, the step S207 (power control process) will be described in detail with reference to FIGS. 6 to 8. Referring to FIG. 6, first, when entering the power saving section, the power control process according to the embodiment of the present application is started (S2071). For example, when the above-described timing check module 1021 generates a power control start signal according to the power saving period entry, the power control process S207 by the control unit 105 is recognized as a start signal. It is also possible to. Also, in relation to this, it is preferable to provide a visually identifiable indication (eg, a power control icon, a notification message) to the user through the display unit 106 described above while the power control process S207 is in operation.

When the power control process is started, first, the cumulative amount of power used in the current power saving period i is compared with the reference value THS # i of the power saving period i (S2072). As a result of the comparison of S2071, if the cumulative power consumption in the power saving period does not exceed the reference value THS # i of the current power saving period, control is performed in the normal mode (S2074). The normal mode is a control method based on maintaining a power control method applied at a corresponding time. For example, referring to the graph of FIG. 9, in the power saving period # 1, the power saving period # 2, the power saving period # 3, and the power saving period #n, the cumulative power consumption 901 is a corresponding power saving period reference value (for example, THS # 1, THS # 2, THS # 3, THS # n) do not exceed, all power control is performed in the normal mode.

However, if the S2071 comparison result, if the cumulative power consumption in the power saving period exceeds the current value (THS # i) of the current power saving period, the control mode is entered, and at this time, the instantaneous power is checked (S2973). One of the first control mode S2076 and the second control mode S2077 may be determined by comparing the amount of power with the set instantaneous reference value (S2075). That is, for example, referring to the graph of FIG. 9, in the power saving section # 4, a section 910 in which the cumulative power consumption 901 exceeds the corresponding power saving section reference value THS # 4 occurs, and the corresponding section ( During 910, the instantaneous power value currently being used within the customer is compared with the set instantaneous reference value THI. That is, if the instantaneous power value currently being used does not exceed the instantaneous reference value, the first control mode (for example, 'power saving mode') is performed (S2075). If exceeded, the second control mode (for example, the blocking mode) is performed (S2076). Specifically, referring to the graph of FIG. 10, for example, in the excess period 910 of FIG. 9, the second control mode is performed during the period 1001 in which the instantaneous power exceeds the reference value THI. The first control mode will be performed for the remaining period.

In relation to this, the first control mode S2076 may proceed, for example, as shown in the flowchart of FIG. 7. First, when the first control mode is started, the power consumption for each electronic device in the current consumer is checked (S2076a). After that, it is checked whether there is an electronic device that focuses on the average power consumption of each electronic device (S2076b). For example, the average power consumption for each electronic device may be preset by the controller 104. Specifically, for example, as the average amount of power applied to the power saving period of the electronic device shown in FIG. 1, the air conditioner 22 consumes 700W of power for 1 hour in the power saving period, and the refrigerator ( 23) is the average power of all the time spent in the power saving period at 100W power consumption, TV 24 is the average power consumption of 2 hours in the power saving period at 200W power consumption, and washing machine 25 saves at 100W power consumption You can set the hourly usage as the average power in the section.

Thereafter, the controller 104 may provide a user notification message for the electronic device exceeding the average amount of power, and may utilize the aforementioned display unit 106 and / or display means of the electronic device. After that, additional control selections (e.g., power-off of the electronic device) are executed by the user, or if the user does not have a control command for a certain time, power saving control of the electronic device is automatically performed. It is performed (S2076d). For example, the control method performed in step S2076d may perform power control in consideration of characteristics of the corresponding electronic device. Specifically, for example, in the case of the air conditioner 22, a power saving mode for raising the target temperature, in the case of the refrigerator 23, a power saving mode for preventing overcooling, and in the case of the TV 24, screen brightness and / or size In the power saving mode to reduce the, the washing machine 25 can be operated in a power saving mode to suspend the washable operation.

In relation to this, the second control mode S2077 may proceed as shown in, for example, the flowchart of FIG. 8. First, when the second control mode is started, the power consumption for each electronic device in the current consumer is checked (S2077a). Thereafter, each electronic device is classified as a necessary and unnecessary electronic device (S2077b). Subsequently, the controller 104 may provide the classification result as a user notification message, but may utilize the aforementioned display unit 106 and / or display means of the corresponding electronic device. For example, if the air conditioner 22, TV 24, indoor lighting equipment, etc. are classified as unnecessary electronics, and the refrigerator 23 and the washing machine 25 are necessary electronics, they are notified to the user in the form of a notification message. , Perform additional control selections (e.g., power off the electronic device yourself), or automatically perform power saving control on the electronic device if there is no user control command for a certain period of time. (S2077d). In the control method performed in step S2077d, for example, the electronic device classified as the necessary electronic device will perform power control considering the characteristics of each electronic device in the same manner as in step S2076d. On the other hand, the electronic devices classified as unnecessary electronic devices may be operated in a blocking mode for preventing additional power generation by performing a power cut.

In addition, the controller 104 may perform the step S2077e of adjusting the set instantaneous power reference value THI to a lower lower level reference value M-THI. The step S2077e may be performed by a selective determination by the user or the controller 104. If the instantaneous reference value is adjusted to a low value, a lower reference value (M-THI) is applied when comparing the reference value in step S2075. The probability of proceeding to the secondary control mode S2077 having a greater control intensity than the primary control mode S2076 is increased. As a result, the controller 104 takes into account the position of the current power saving period in relation to the entire billing period, and actively controls power so as to satisfy a range not exceeding the final control target power saving target reference value Max-P. It can be done.

While executing the primary control mode (S2076) or the secondary control mode (S2077), the controller 104 checks whether the current power saving period is terminated (S2078), and if the power saving period is continued, returns to the step S2072. Power control is continued. Therefore, even during the power saving period, the power control mode is changed to, for example, the normal mode (S2074)-> the primary control mode (S2076)-> the secondary control mode (S2077), or, for example, the normal mode ( S2074)-> secondary control mode (S2077)-> primary control mode (S2076)-> normal mode (S2074) can also be changed. This means that power control (eg, cumulative usage, instantaneous usage) and active reference value can be actively controlled by comparing the set reference value. When the corresponding power saving section ends in step S2078, the power saving control process ends (S2079).

Steps S2071 to S2079 illustrate detailed operations of the power saving section power control process S207. As described above, step S207 is performed for all power saving sections in the entire charging section and when the charging section is finished (S208). ), The power control process is terminated, and for the next charging section, a new power saving period and a power saving target amount are received, and are performed again from the above-described step S203 (section setting step) and step S204 (reference value setting step). Of course, if the power saving section and the power saving target applied to the next billing section are the same as the power saving section and the power saving target applied to the previous charging section, steps S203 (section setting step) and S204 (reference value setting step) may be omitted.
