The smart grid includes a power plant generating electricity through thermal power generation, nuclear power generation, or hydroelectric power generation, and a photovoltaic power generation plant and a wind power generation plant using solar power or wind power .

The thermal power plant, nuclear power plant or hydroelectric power plant transmits electric power to the electric power plant through a transmission line, and electric power is sent to the substation in the electric power plant so that electric power is distributed to the consumer such as the home or the office.

Electricity generated by renewable energy is also sent to the substation and distributed to each customer. Electricity transmitted from the substation is distributed through the electric power storage device to the office or each household.

Even in the home using a home network (HAN), it is possible to produce electricity by itself through the fuel cell mounted on sunlight or PHEV (Hybrid Electric Vehicle, Plug in Hybrid Electric Vehicle) The remaining electricity can be returned to the outside.

In the office or home, a smart measuring device is provided to grasp real-time power and electric charges used in each customer. Through this, the user recognizes the current amount of electric power and the electric charge, Can be considered.

In addition, since the power plant, power station, storage device, and consumer are two-way communication, it is necessary to notify the storage device, the power station and the power station of the situation of the demanding place separately from the one- Electric distribution can be performed.

Meanwhile, in the above-mentioned smart grid, an Energy Management System (EMS) and an Advanced Metering Infrastructure (AMI), which measure real-time power communication and power consumption of a customer in real time, It is responsible for the role of

The measurement device under the Smart Grid is based on an open architecture and is an underlying technology to integrate consumers. It provides consumers with the ability to use electricity efficiently, and power suppliers to detect system problems and efficiently operate the system do.

Here, open architecture is a standard that allows all electric devices to be connected to each other regardless of which manufacturer manufactures the electric devices in a smart grid system, unlike a general communication network.

Thus, the metering devices used in the Smart Grid enable consumer-friendly efficiency concepts such as "Prices to Devices ".

That is, the real-time price signal of the electric power market is relayed through the energy management device (EMS) installed in each home and the smart meter, and the energy management device (EMS) and the smart meter communicate with each electric product, Energy and cost can be saved by recognizing the electric power information of each electric appliance by the EMS or the smart meter and performing the power information processing such as the setting of the consumed electric power or the electricity rate limit based on the electric power information.

Meanwhile, it is also possible to collect status information on the operation mode of each electric appliance in each of the electric appliances, receive environmental information such as electric power information or temperature or humidity received from the energy management device (EMS) or the smart meter, A smart control device is provided that reflects the operation control of the product.

The control for each electrical product can be performed by communication between the smart control device, the energy management device (EMS), and the smart meter.

Here, the energy management apparatus (EMS) performs bidirectional communication with the local energy management apparatus (Local EMS) and the local energy management apparatus (EMS) used in the office or the home to collect information collected from the local energy management apparatus (Central EMS) that processes the energy.

Since the smart grid enables real-time communication of power information between the supplier and the consumer, it is possible to realize a "real-time power grid reaction ", thereby reducing the high cost required to meet the peak demand.

Fig. 2 shows the power communication network 10 in a home, which is a major demand source of the smart grid.

The power communication network 10 includes a smart meter 20 capable of receiving electric power information such as electric power and electric power charges to be supplied to each household from outside and measuring the electric power used and power charges in the household in real time, (EMS) 30 connected to the smart meter 20 for communicating with and controlling the operation of one or more appliances.

Thus, the smart meter 20, the energy management device (EMS) 30, and the electrical product constituting the power communication network 10 can be referred to as a communication component.

That is, certain elements in the power communication network 10 may communicate with other elements to exchange information, and certain elements may control or control other elements depending on the information.

Here, the energy management device (EMS) 30 includes a screen 31 for displaying the current power consumption state and external environment (temperature, humidity), and includes an input unit 32 and the like It is preferable that the terminal is provided in the form of a terminal.

The EMS 30 is again connected to an electric appliance such as a refrigerator 101, a washing machine and a dryer 102, an air conditioner 103, a TV 105 or a cooking appliance 104 through a home network (100), and performs bidirectional communication with them.

Communication within the house can be done via wire or wireless, such as a PLC.

Further, it is preferable to arrange each electric appliance so as to be connected to other electric appliances so as to be able to communicate with each other.

The power supply source 50 for supplying power to the home includes a system power source 51 having general power generation equipment (thermal power, nuclear power, hydro power) or generating power using renewable energy (solar, wind, geothermal) ), And a power company such as KEPCO will be a representative example.

In addition, the home power generation facility 52 such as a photovoltaic power generation facility provided in each home, or the fuel cell 53 provided in a home or a vehicle may be another power supply source.

Typically, the power supply 50 is connected to the smart meter 20 and the energy management device 30 to provide power information to the smart meter 20 and the energy management device 30, and the information thus provided is used as basic information for controlling each electric appliance do.

The information provided from the power supply source 50 may be transmitted directly to each communication device (not shown) provided in each of the electric products 100 without passing through the smart meter 20 and the fraudulent energy management device 30 So that it is possible to directly provide information for controlling the operation of the specific electric appliance of each household, such as the electric utility company 51. [

FIG. 3 illustrates an embodiment of an energy management device (EMS), which is in the form of a terminal with a touch panel 33.

The touch panel 33 is provided with information such as the current electricity usage amount and the electricity rate, the estimated rate estimated by the accumulated history, and the carbon dioxide generation amount, the electricity rate of the current time interval, the electricity rate of the next time interval, A screen 31 on which real-time energy information and weather information including a time zone in which the electricity rate is changed is displayed.

The screen 31 of the touch panel includes a graph showing the amount of power consumed by each household appliance and the change in the power consumption by time slot.

Also, matters concerning whether or not the power is supplied for each product are displayed in ON / OFF state.

An input unit 32 is provided at one side of the screen 31 to allow the user to set an operation of the electric product as required.

By using the input unit 32, the user can set the amount of electric power or the limit of the electric charge he / she intends to use. According to the setting, the energy management apparatus (EMS) 30 can control the operation of each electric appliance .

Figure 4 shows a control block diagram of a power supply 50 under a smart grid and a power communication network responsible for powering electrical appliances in the home.

As described above, the power supply source 50 may be the system power supply 51, the self power generation facility 52, or the fuel cell 53.

The power source 50 may be connected to the smart meter 20 or may be connected to the energy management device (EMS) 30.

The EMS 30 includes a control unit 35 and an input unit 38, a communication unit 34, and a display unit 39.

The communication unit 34 communicates with the home appliance 100, that is, the refrigerator 101, the washing machine or the dryer 102, the air conditioner 103, the cooking apparatus 104, And transmits and receives information and driving information.

The control unit 35 can grasp the setting information inputted by the user by the input unit 38, the operation history and the electric power usage history information of the electric equipment which are accumulated in the past and the amount of electric power supplied from the outside, To control the operation of electrical products, and to control the power supplied to these electrical products.

Hereinafter, a situation will be described in which the operation of the energy management device 30 or the smart meter 20 or the electric appliance itself is controlled in order to reduce the electric power charge in response to the change in the electric power charge with time .

The control unit is collectively referred to as the energy management device 30 or the smart meter 20 that conducts the control operation of the electric product, or a control unit that is built in the communication component such as an electric product.

As shown in FIG. 5, the control device recognizes the operation state information of the electric appliance (S501).

The operation state information includes a desired operation mode of the electric appliance desired by the user and a predicted operation required time.

On the other hand, an operation mode or an operation time period of the electric appliance for processing the load based on the load applied to the electric appliance is included in the operation state information.

Examples of the load include weight, material, etc. of the laundry when the electric appliance is a washing machine, and the weight of the drying subject when the dryer is a dryer. Also, in the case of an air conditioner, the degree of temperature change of the room will be the degree of change. In the case of a refrigerator, the degree of temperature change in the storage compartment falls within the category of the load.

Then, power information including a power rate that varies with time is recognized (S502).

The step of calculating, recognizing, and displaying expected power consumption information in operation of the electrical product in accordance with the operation state information may also be included.

Here, the estimated power consumption information includes at least one of an estimated power consumption rate and an estimated power consumption amount (S503).

Thereafter, it is determined whether the estimated power consumption information is equal to or less than a predetermined reference value. For example, it is determined whether the estimated power consumption rate required when the desired operation mode is performed in the current or desired operating time zone exceeds the reference power consumption rate based on the user (S504).

If it is determined that the estimated power consumption information is less than the predetermined reference value, the desired operation mode may be performed in the current state or the desired time period, so that the operation is performed in a predetermined state (S511).

If it is determined in step S504 that the estimated power consumption information does not exceed the predetermined reference value but exceeds the predetermined reference value, it is determined whether or not the power saving operation is selected (S505).

As a result of the determination, if the power saving operation is not performed, the desired operation mode may be performed in the desired driving time zone (S511).

However, if it is decided to perform the power saving operation for reducing the electric power charges, first, it is determined whether the user desires to change the operation time zone (S506).

The concept of the power saving operation includes both operation for reducing power consumption or operation for keeping the power consumption unchanged while operating the electric appliance in a time period in which the electric power charge is low.

That is, this means that the operation state information (operation mode, operation time) described above is changed.

If the user wishes to change the driving time period, he or she will follow the control flow of changing the driving time period from the desired driving time period to another driving time period while maintaining the desired driving mode.

 However, if the user does not want to change the driving time period, the electric appliance is operated in the desired driving time zone, and the power saving operation for reducing the electric power charge is performed (S507).

That is, by changing the operation mode, the power consumption and the electric power charge are reduced.

If the user desires to change the operation time zone in step S506, the user is informed of the power charges for each time zone. At this time, the displayed power rates for the time zones are the power per time zone (S508).

Then, it is determined whether the user selects a specific time zone among the power rates for the displayed time zones (S509). If so, the electric appliance operates in the desired driving mode in the time zone selected by the user (S510).

FIG. 6 is a diagram illustrating a state change in an electric appliance or an energy management apparatus to implement the control method according to the present invention.

Herein, the operation control of the washing machine is shown, but the present invention is not limited to this, and can be applied to all electric appliances such as a refrigerator, an air conditioner, a cooking appliance, and the like.

First, as shown in Fig. 6 (a), the user puts the laundry into the washing machine and selects the desired operation mode. In this figure, a standard course was selected.

When the desired operation mode is selected, the estimated time required to perform the desired operation mode and expected power consumption are automatically displayed.

It is desirable that the expected power consumption charge to be imposed when performing the desired operation mode in the current time zone or the desired time zone is also displayed.

Then, as shown in Fig. 6 (b), power information such as electric power charge information is received from outside and is displayed, and the power saving possible time can also be recommended.

Here, the power save time is preferably recommended in a time zone in which the estimated power consumption rate is lower than the preset reference power consumption rate.

On the other hand, when the user selects the washing start time in FIG. 6 (b), the user is instructed to select the washing time by displaying the power charges for each time period as shown in FIG. 6 (b).

7 (a) to 7 (c) show examples in which the operation time is shifted to the off-peak time in order to reduce the power consumption charge when the operation time of the desired operation mode belongs to the on-peak time period, The electric power consumption of the electric appliance is reduced while the driving state of the electric appliance is maintained.

As shown in FIG. 8, the on-peak time period is a relatively expensive time period in which the electric power charge per hour is higher than a predetermined reference level. The off-peak time period refers to a relatively low time .

As shown in FIG. 7 (a), when the estimated power consumption price of the electric appliance is lower than a predetermined reference (desired consumption of the user) in the on-peak time period in which the user first desires a desired driving time period (time zone between the desired start time and desired end time) Electric power charges) or more.

At this time, as shown in FIG. 7 (b), the control device determines whether or not the other guided driving time zones (for example, Between the guided start time and the guided end time) to allow the appliance to operate in that time period.

Alternatively, instead of shifting the time zone, the operation in the on-peak time interval may be performed as in step S507 of FIG. 5, but the operation mode may be changed from the desired operation mode to another operation mode to reduce the electric power consumption of the appliance, (See Fig. 7 (c)).
