A network system according to another aspect includes: a first component having a first communication means; And a second component having second communication means for communicating with the first communication means, wherein the first component is capable of predicting information relating to operation of the second component.

According to the present invention, a plurality of components communicate with each other to recognize energy information and additional information, thereby enabling effective management of an energy source.

In addition, since the energy information and the additional information related to the selected operating condition of the user can be predicted, the user can easily confirm the energy information and the additional information for the desired operating condition, The convenience is improved.

Referring to FIG. 3, in the network system of the present invention, the specific component C can receive information related to energy (hereinafter, "energy information") by communication means. Further, the specific component (C) can be configured to include additional information (environmental information, program update information, time information, operation or status information of each component (failure), and consumer habit information using the energy consumption unit Can be further received.

The environmental information may include carbon dioxide emission amount, carbon dioxide concentration in air, temperature, humidity, rainfall amount, rainfall amount, insolation amount, air amount, and the like.

On the other side, the information includes internal information such as information related to each component (operation or status information (failure) of each component, energy use information of the energy consumption part, consumer habit information using the energy consumption part, etc.) (Energy related information, environmental information, program update information, and time information).

At this time, the information can be received from other components. That is, the received information includes at least energy information.

The specific component may be one component that constitutes the utility network 10 or one component that constitutes the home network 20.

The energy information I may be one of electricity, water, gas, and the like as described above.

For example, the types of information related to electricity include time-based pricing, energy curtailment, grid emergency, grid reliability, energy generation amount, (operation priority), and energy consumption amount (energy consumption amount). In this embodiment, the charge related to the energy source is an energy charge.

That is, energy related information can be classified into charge information (energy charge) and non-charge information (energy reduction, emergency situation, network safety, power generation, operation priority, energy consumption, etc.).

Such information can be divided into scheduled information generated in advance based on previous information and real time information that varies in real time. The schedule information and the real-time information can be classified according to the prediction of the information after the present time (future).

The energy information I may be divided into time of use (TOU) information, critical peak pattern (CPP) information, or real time pattern (RTP) information according to a change pattern of data over time. The energy information I may vary with time.

Referring to FIG. 4 (a), according to the TOU information, data is changed stepwise according to time. According to the CPP information, the data changes stepwise or real-time with time, and emphasis is displayed at a specific time point. That is, in the case of the CPP pattern, the general charge is cheaper than the charge of the TOU pattern, but the charge at the specific point in time is significantly more expensive than the charge in the TOU pattern.

Referring to FIG. 4 (b), according to the RTP information, data changes in real time according to time.

On the other hand, the energy information I may be transmitted or received as true or false signals such as Boolean on the network system, actual price information may be transmitted or received, or a plurality of levels may be transmitted and received. Hereinafter, an example of information related to electricity will be described.

When the specific component C receives a true or false signal such as a Boolean signal, it recognizes one of the signals as an on-peak signal and the other signal as an off-peak ) Signal.

Alternatively, the specific component may recognize at least one or more energy information including the electricity bill, and the specific component may compare the recognized information value with the reference information value to determine on-peak and off- peak) can be recognized.

For example, when a specific component recognizes leveled information or actual price information, the specific component compares the recognized information value with the reference information value to determine on-peak and off-peak values, Lt; / RTI >

At this time, the recognized information value may be at least one of an electricity rate, a quantity of electricity, a rate of change of the electric rate, a rate of change of the quantity of electricity, an average value of the electricity rate and an average value of the electric quantity. The reference information value may be at least one of an average value, an average value of a minimum value and a maximum value of power information during a predetermined section, and a reference change rate of power information during a predetermined section (for example, a slope of power consumption amount per unit time).

The reference information value may be set in real time or set in advance. The reference information value may be set in a utility network or set in a home network (input by a consumer direct input, energy management unit, central management unit, etc.).

If the specific component (eg, energy consuming unit) recognizes an on-peak (recognizes information related to the reduction of energy bills or energy consumption) (eg, when it recognizes) Stop or stop state) output can be reduced. The specific component may determine the driving method in advance before starting the operation, and may change the driving method when the on-peak is recognized after the operation starts.

And, if a particular component recognizes off-peak, it can recover or increase its output when needed. That is, when a specific component recognizing the on-peak recognizes an off-peak, the output may be restored to its previous state or may be increased (different from the previous state) than the previous output.

At this time, the total consumed power and / or the total electricity use charge during the entire driving time of the specific component is reduced, even when the output of the specific component is recovered or the output is increased after recognizing the off-peak.

Alternatively, when the specific component recognizes an on-peak (for example, a recognition time point), the output can be maintained if it is an operable condition. At this time, the operable condition means that the information value of the driving is below a certain standard. The information value regarding the drive may be an electricity rate, an amount of power consumption, a time relating to energy or information on operation time, and the like. The constant criterion may be a relative value or an absolute value.

In one example, the operable conditions are, for example, when the on-peak interval is less than a predetermined time, when the operation remaining time is less than a predetermined time, when the energy charge when operating in the on- And the ratio of the on-peak period of the entire operation time when the energy consumption is less than a predetermined amount.

At this time, if the operating start point of the component is included in the on-peak period in the non-operating state of the component, the output of the component can be maintained if the operable condition is satisfied.

The predetermined criteria may be set in real time or may be set in advance. The predetermined criteria may be set in the utility network or in a home network (input by a consumer direct input, energy management unit, central management unit, etc.).

Alternatively, the output may be increased if the particular component recognizes an on-peak (for example, a point-in-time). However, even when the output is increased at the time when the on-peak is recognized, the total output amount during the entire driving period of the specific component can be reduced or maintained to be less than the total output amount when the specific component operates at the normal output.

Alternatively, the total power consumption or total electricity charge during the entire drive period of a particular component, even when the output increases at the time when it recognizes the on-peak, is the total power consumed or total It can be reduced than the electricity rate.

That is, after the output of the specific component increases, the output of the particular component may be reduced or the output may be zero.

If the specific component recognizes an off-peak (for example, a recognition time point), the output can be increased. For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first.

Further, in the case of a refrigerator, it is possible to store the hot water in the hot water tank by supercooling the output by increasing the output from the existing output, or by driving the heater before the expected operation time of the heater in the case of the washing machine or the washing machine. This is to operate the off-peak in advance to be operated at an on-coming peak to reduce the energy charge.

Or when a particular component recognizes an off-peak (for example, when it is recognized).

Or if the specific component recognizes an off-peak, the amount of generated electricity (or supplied amount) can be reduced.

In the present invention, the particular component (e.g., the energy consuming unit) may maintain, reduce or increase the output. Thus, a particular component may include a power changing component. Since the power can be defined by current and voltage, the power variable component may include a current regulator and / or a voltage regulator. The power variable component may, for example, be operated in response to an instruction issued from the energy manager.

On the other hand, the energy curtailment information is information related to a mode in which the component is stopped or the electricity fee is reduced. That is, the energy reduction information is information related to the reduction of the energy consumption amount or the energy charge. The energy reduction information may be transmitted or received as a true or false signal, such as a Boolean on a network system. That is, a stop signal (turn off signal) or a reduction signal (lower power signal) can be transmitted and received.

When the specific component recognizes the energy reduction information, it can reduce the output (when the lower power signal is recognized) or to zero the output as described above (if the stop or stop state is maintained) have.

Or when the specific component recognizes the energy reduction information (for example, when it recognizes it), the output can be maintained if it is an operable condition.

The emergency information (Grid emergency) is information related to a power failure or the like, and can be transmitted and received as a true or false signal, for example, as a Boolean. The information related to the power failure or the like is related to the reliability of components using energy.

If the particular component recognizes the emergency information, it may be immediately shut down.

When the specific component receives the emergency information as the schedule information, the specific component may increase the output before the arrival of the emergency time point and perform the same operation as that of the off-peak of the specific component described above . And, at the time of the emergency, the specific component can be shut down.

The grid reliability information is information about the amount of electricity supplied or the amount of electricity supplied or information about the quality of electric power. The grid reliability information is transmitted or received as a true or false signal such as a Boolean or supplied to a component (for example, The component may determine the frequency of the AC power source.

That is, when the underfrequency of the AC power supplied to the component is detected (recognized), it is judged that the supplied electricity quantity is small. If an overfrequency higher than the reference frequency of the AC power supply is detected (recognized) Can be judged to be many. That is, an underfrequency lower than the reference frequency corresponds to the information related to the reduction of energy consumption or energy bills.

When the specific component recognizes that the amount of electricity is low or the quality of the electricity is poor, the specific component may set the output 0 (stop or stop) depending on the case, as mentioned above, The output can be reduced, the output can be maintained, or the output can be increased.

The electricity generation excess information is information about the state where the electricity consumption of the component consuming energy is smaller than that of the electricity generation and the surplus electricity is generated and can be transmitted or received as a true or false signal such as Boolean.

The output can be increased if the specific component recognizes the generated electricity excess information (eg, when it recognizes grid overfrequency or recognizes an over energy signal). For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first. Further, in the case of a refrigerator, it is possible to store the hot water by supercooling the output by increasing the output from the existing output, or by driving the heater in advance of the expected time of operation of the heater in the case of a washing machine or a washing machine.

When the specific component recognizes information that the energy consumption of the network itself or the home network is large, the output component may be set to output 0 (hold or stop) or to reduce the output , Or increase the output.

The specific component may increase the output if it recognizes that the energy consumption is less than the reference amount.

Specifically, each type of information related to the energy includes first information (I1) that is not processed, second information (I2) that is information processed in the first information, And third information (I3), which is information for performing a function of the component. That is, the first information is raw data, the second information is refined data, and the third information is a command for performing a function of a specific component.

And, energy related information is included in the signal and transmitted. At this time, at least one of the first to third information may be converted only the signal, but the content may be transmitted a plurality of times without being converted.

For example, as shown in the figure, a component receiving a signal including the first information I1 may simply convert a signal and transmit a new signal including the first information I1 to another component.

Therefore, in this embodiment, the conversion of the signal and the conversion of the information are described as different concepts. At this time, it can be easily understood that the signals are also converted when the first information is converted to the second information.

However, the third information may be transmitted a plurality of times in a state in which the contents are converted, or may be transmitted a plurality of times in a state in which signals are converted while maintaining the same contents.

In detail, when the first information is unprocessed electricity rate information, the second information may be processed electricity rate information. The processed electricity bill information is information or analytical information in which electric bill is divided into multiple levels. The third information is an instruction generated based on the first information or the second information.

The specific component may generate, transmit, or receive one or more of the first to third information. The first to third pieces of information are not necessarily sequentially transmitted and received.

For example, a plurality of third information can be transmitted and received in sequence or in parallel without first and second information. Alternatively, the first and third information may be transmitted or received together, the second and third information may be transmitted or received together, or the first and second information may be transmitted or received together.

In one example, when a particular component receives the first information, the particular component may transmit the second information, transmit the second information and the third information, or transmit only the third information.

When a specific component receives only the third information, the specific component can generate and transmit new third information.

On the other hand, in the relationship between two pieces of information, one piece of information is a message and the other piece of information is a response to a message. Accordingly, each component constituting the network system can transmit or receive a message, and can respond to a received message when receiving a message. Therefore, the transmission and correspondence of a message is a relative concept for individual components.

The message may comprise data (first information or second information) and / or instructions (third information).

The command (third information) includes at least one of a data storage command, a data generation command, a data processing command (including generating additional data), an additional command generation command, a further generated command transmission command, Command, and the like.

In this specification, responding to a received message means that it is necessary to store data, to process data (including generating additional data), to generate a new command, to send a newly created command, ), Operation, transmission of stored information, transmission of an acknowledge character or negative acknowledge character, etc.

For example, if the message is first information, the component that received the first information may generate a second information by processing the first information, generate second information, and generate new third information, Only the third information can be generated.

Specifically, when the energy management unit 24 receives the first information (internal information and / or external information), the energy management unit 24 generates the second information and / or the third information, And may be transmitted to one or more constituent components (e.g., an energy consuming unit). The energy consuming unit 26 may operate according to the third information received from the energy managing unit 24. [

Since the electric charge may vary with time, the memory unit stores electric power information when one or more energy consuming units operate, and the controller 71 uses the electric charge information and the electric power information received from other components You can calculate the electricity bill.

Of course, the memory unit 74 stores energy information when operating in the fixed mode.

Therefore, the user can confirm the predicted energy information and the predictive supplementary information when the component operates under the condition selected by the user. Accordingly, the user can check the predicted information to determine whether to start the operation, or to reset the condition, thereby finding a condition in which the performance is improved with less energy use charge.

The operation mode information (operation factor information) related to the predicted information may be stored in the memory unit 74 using the mode selection unit. The operation mode stored in the memory unit 74 with respect to the predicted information may be referred to as a user preference mode. At this time, a plurality of user preference modes may be stored in the memory unit.

If the user selects a specific user preference mode using the mode selection unit, the component can operate in the selected mode.
