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.

In another aspect, the information includes internal information such as information relating to each component (operation or status information (failure) of each component, energy usage information of the energy consumption unit, consumer habits information using the energy consumption unit, etc.) (Energy-related information, environmental information, program update information, and time information), which are 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, a particular component may recognize information about at least one drive that includes an electricity bill, and the particular component may compare on-peak and off-peak values by comparing the recognized information value with a reference information value off-peak.

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 information value about the driving may be at least one of an electricity rate, a power rate, a rate of change of the electricity rate, a rate of change of the electric power rate, an average value of the electricity rate and an average value of the electric power amount. 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 (for example, the energy consuming unit) recognizes an on-peak (for example, a recognition time point), the output may be set to 0 (stop or stop) and the output may 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 particular component that recognizes an on-peak recognizes an off-peak, the output can be restored to its previous state or increased further 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, if the specific component recognizes an on-peak (for example, a recognition time point), the output can be maintained if the condition is operable. At this time, the operable condition means that the information value of the driving is below a certain standard. The information value of the driving may be information on an electric charge, an amount of power consumption, or an operation time. The constant criterion may be a relative value or an absolute value.

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 of recognizing the on-peak, It can be reduced than the electricity rate.

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 in the case of a washing machine or a washing machine, by driving the heater ahead of the scheduled operation time of the heater. This is to operate in off-peak in advance to be operated at an on-peak to be reached in the future, thereby reducing electric charges.

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

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 according to an instruction issued from the energy management unit.

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. 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.

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 arriving at the emergency time point and perform the same operation as the operation at 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 determined 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.

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 operation time of the heater in the case of the washing machine or the washing machine.

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. [

Referring to FIG. 5, the first component 31 of the home network 20 may communicate directly with the utility network 10. The first component 31 may communicate with a plurality of components 32, 33, 34 (second to fourth components) of the home network. It is noted that there is no limit to the number of components of the home network that communicate with the first component 31 at this time.

That is, in this embodiment, the first component 31 serves as a gateway. The first component 31 may be, for example, one of an energy management unit, an energy measurement unit, a central management unit, an energy network auxiliary unit, an energy consumption unit, and the like.

A component acting as a gateway in the present invention not only enables communication between components communicating using different communication protocols, but also enables communication between components communicating using the same communication protocol.

Each of the second to fourth components 32, 33 and 34 may be one of an energy generating unit, an energy distributing unit, an energy managing unit, an energy storing unit, an energy measuring unit, a central managing unit, have.

The first component 31 may receive information from the utility network 10 or one or more components that make up the utility network 10 and may forward or process the received information so that the second component- (32, 34). For example, when the first component 31 is an energy measurement unit, the first component may receive electric bill information and transmit it to an energy management unit, an energy consumption unit, and the like.

And each of the second to fourth components can communicate with another component.
