Description

REDUCING SYSTEM OF ELECTRIC POWER CONSUMPTION USING DEMAND RESPONSE EVENT AND THE REDUCING METHOD THEREOF}

The present invention relates to a power consumption reduction system and a reduction method using a demand response event, and more particularly, the event to reduce the power demand of the end customer at the point where it is necessary to reduce the power consumption, and reduce the event result The present invention relates to a power consumption reduction system and a method for reducing power consumption using a demand response event to pay end users with incentives proportional to the amount of power consumed.

In mid-August or cold season in July-August, the use of electric appliances such as air conditioners and heaters is rapidly increasing, causing the power reserve to drop below 5%. If the power reserve is lowered, there should be a way to raise the power reserve above a certain level, as the power supply can be disrupted even if one or two power plants are shut down due to failure or periodic inspection.

In order to increase the electricity reserve ratio in terms of supply, measures such as reducing power loss by building more power plants or improving transmission and distribution facilities are implemented.In demand terms, refrain from using excessive air conditioners in the summer, and at home, office, public facilities, etc. Campaigns may also be conducted to keep room temperatures above acceptable levels.

The solution of increasing supply is expensive and is treated in an undesired way because it causes many environmental problems, such as an increase in carbon dioxide emissions due to increased use of oil or coal.

However, the method of suppressing electricity demand through voluntary participation of citizens is efficient because it can bring about environmental improvement effects, but there are limitations that simple promotions and campaigns can not achieve their intended purpose without special rewards or incentives.

The present invention for solving the above-mentioned problems is to reduce the power consumption by the voluntary or pre-set compulsory manner by reducing the power consumption load of the end customer when the power demand is high, it is necessary to reduce the power consumption of the end customer. It is an object of the present invention to provide a system and method for reducing power consumption using a demand response event that can prevent disruptions.

The present invention devised to solve the above-mentioned problems is an end-user in accordance with the power consumption DR (Demand Response) event that is performed by an independent system operator (ISO) that manages power transmission and price through a load aggregation (LA) operator. An energy saving system that reduces power consumption, stores information on electrical appliances used by end customers participating in the DR event, notifies the user of event contents transmitted from the LA operator, and sets whether to participate in the event on a display. A wall pad providing an interface capable of being connected; And a smart outlet connected to the wall pad in a short-range wireless communication mode to exchange data and control an amount of power supplied to the electrical appliance, wherein the ISO stores power saved by the terminal customer during the DR event. Incentives proportional to the amount used, characterized in that paid to the end-user.

The wall pad is characterized in that the internal structure of the terminal customer and the arrangement of the electrical appliances used in the terminal customer is converted into image information and stored.

The wall pad reduces the power consumption of the end customer by controlling the smart outlet to cut off the power supplied to the electrical appliance or reduce the power supply during the DR event in which the end customer participated, the ISO end Incentives proportional to the power consumption saved while the customer participates in the DR event is characterized by paying the end customer.

The power consumption saved by the terminal customer is a value obtained by subtracting the power consumption actually used during the DR event participation time from the estimated power consumption preset for the terminal customer.

According to another embodiment of the present invention, a method of reducing power consumption of an end customer by a power consumption reduction system according to a power consumption DR event that an ISO managing power transmission and price is performed through an LA operator is provided. A first step of inputting the personal information of the terminal customer in order to participate in the DR event, so that the saving system transmits and stores the personal information of the terminal customer to the LA operator or the ISO; When the end customer is registered as a participant load by describing the load type and load amount of the electrical appliance used in the end customer, the saving system transmits the information about the participant load to the LA operator or the ISO to store the second load. Steps; A third step of displaying, on the display, the announcement by the wall pad included in the saving system when the ISO announces the DR event to the end-users through the LA operator; During the DR event in which the end customer participates, the wall pad controls the smart outlet included in the saving system to cut off the power supplied to the electrical appliance or reduce the power supply to reduce the end user's power consumption. A fourth step; After the DR event is finished, the ISO calculates an incentive proportional to the power consumption saved by the terminal customer and transmits the incentive to the wall pad, and the wall pad displays the transmitted incentive information on a display. ; And a sixth step in which the ISO pays the determined incentive to the terminal recipient.

The power consumption saved by the terminal customer is a value obtained by subtracting the power consumption actually used during the DR event participation time from the estimated power consumption preset for the terminal customer.

The wall pad stores information on electrical appliances used in the end customer participating in the DR event, and the smart outlet is connected to the wall pad in a short-range wireless communication method to exchange data.

In the fourth step, when the DR event in which the terminal customer participates is a direct load control program, the wall pad reduces the power supply when the DR time starts, and restores the power supply again when the end time arrives. It is characterized by controlling the smart outlet.

In the fourth step, if the DR event participated in the end event is a load blocking / load reduction program or an emergency demand response program, the wall pad may check whether the end customer participates before the DR event starts. Display the screen on the display, and after the participation in the program is confirmed, when the start time of the DR event, the power supply is reduced, and when the end time, the smart outlet is controlled to restore the power supply again. It is done.

The fifth step is a penalty proportional to the size of the actually used power consumption and the expected power consumption, if the actual power consumption used during the event is greater than the expected power consumption preset for the terminal customer The settlement is transmitted to the wall pad, and the wall pad displays the transmitted penalty information on the display, and the sixth step is characterized in that the ISO imposes the determined penalty on the end-user.

In the fourth step, when the DR event in which the terminal customer participates is an automatic bidding program, the wall pad transmits and stores the incentive information input by the terminal customer to the LA operator or the ISO, and the terminal customer selected as a successful bidder The wall pad may control the smart outlet to reduce the power supply when the start time of the DR event and to restore the power supply when the end time comes.

The ISO or the LA operator may select a place where the smallest incentive is presented as a successful bidder based on the input incentive information.

According to the present invention, it is possible to reduce the power consumption of the consumer during the period in which the demand for power is increased, it is possible to reduce the cost of installing additional power equipment, it is possible to prevent industrial damage due to limited power transmission, etc. .

In addition, according to the present invention, the general electric power consumers can receive cash or other benefits proportional to their power consumption, thereby actively participating in demand reduction events.

Hereinafter, a power consumption reduction system and a reduction method (hereinafter, referred to as a “saving system” and a “saving method”) using a demand response event according to an embodiment of the present invention will be described with reference to the drawings.

1 is a block diagram showing a connection state of a saving system according to an embodiment of the present invention.

Saving system 100 of the present invention is installed in the end water service (home, office, factory, mall, etc.) facilities, and is connected to the ISO 200 and LA operator 300 through the network. The energy saving system 100 may be referred to as a home energy management system (HEMS), and measures a load installed in an end customer and controls an operation state. In addition, the demand pattern is changed by remotely controlling the load in response to a DR (Demand Response) event according to the load control information input to the basic setting of the saving system 100.

The saving system 100 may control the operation by the user using the external PC 10.

The energy saving system 100 notifies the DR event and provides an interface for setting an event participation. The wall pad 102 is connected to the wall pad 102 in a short-range wireless communication method to exchange data and to supply power. It includes a smart outlet 104 that can control in real time. Each of the plurality of smart outlets 104 is connected to a power source of the electrical appliance 20.

The DR event for power saving of the present invention measures the power saved by participating in the DR event and the power consumed by the electrical appliance 20 in the normal state by using the reduction system 100 installed in a home or office, On the basis of determining incentives or penalties to be imposed on the user.

The DR event is planned and executed by an independent system operator (ISO) 200. The ISO 200 is an independent service operator that is responsible for power transmission management and power price management. In Korea, since it is not a variable price system, there is no ISO (200) in the strict sense, but the Korea Electric Power Exchange (KPX) plays a role.

ISO 200 serves as a notification and implementation of DR events, installation of a savings system 100 for end customers.

The ISO 200 is equipped with a Demand Response Automation Server (DRAS), which transmits a DR event to the savings system 100 through the LA provider 300 when the DR event service provider (ISO) operates the DR service. It provides automated DR service through communication.

The LA operator 300 stands for Load Aggregation, and distributes DR event information received from the DRAS to the saving system 100 in the terminal customer. In addition, the DR system receives the load information of the end customer from the saving system 100 and performs the DR service with appropriate load control for each DR event.

The DR event is notified by the ISO 200 through the DRAS with information such as a DR service execution time and method. The DR event generated by the ISO 200 is delivered to the n LA operators 300 through the DRAS, and the LA provider 300 analyzes the DR event and distributes the DR event to the savings system 100 within the terminal customer.

2 is a flowchart illustrating a process of implementing and participating in a DR event.

DR events are divided into three types: A type, B type, and C type.

Type A is a program (direct load control program) in which the utility company or ISO 200 stops or restarts the load of the terminal customer remotely through the LA operator 300 after a short notice. In other words, when the DR event begins, the terminal customer load is forcibly reduced, and the incentive corresponding to the reduced load at the end of the event is calculated and paid. Therefore, end-users can only decide whether to participate in DR events, not the amount of load or incentive to save. Type A features are compulsory and insurable.

Type B provides compensation for discounts or reductions, incentive payments, etc., instead of agreeing to reduce the load for a certain period of time, in case of an accident in the power system or when the power usage is expected to increase. Program (load cut / load reduction program, emergency response program).

For type B DR events, the pre-contract between ISO 200 and end-users takes precedence, and if the load is reduced according to the contract details, incentives are provided according to a fixed form and amount. If the customer does not reduce the power consumption even after attending the event, the customer will be penalized (penalties, surcharges, etc.). The terminal consumer can autonomously determine whether or not to participate in the event. Type B guarantees autonomy of participation, but once it participates, anti-compulsive load reductions are made due to incentives or penalties.

Type C is an auction-based program (automatic bidding program) in which end-customers offer incentives for load reduction. When the ISO 200 announces the DR event time, the end-acceptor may be awarded a load reduction amount while presenting an incentive. In the event of a successful bid, the end-user must change the load pattern and will be penalized for failing to reduce the load by the winning bid.

Type C participates autonomously and determines incentives by auction.

The user selects a method best suited to his or her lifestyle from three types of events, and participates in the DR event. It is also possible to simultaneously participate in multiple events.

In order to participate in the DR event, the savings system 100 must be installed in the terminal customer. The savings system 100 includes a wall pad 102 and a plurality of smart outlets 104.

The wall pad 102 included in the energy saving system 100 has an interface that can be connected to other devices in a manner such as short-range wireless communication or wired Internet. The PC 10 connected to the wall pad 102 is a general computer terminal installed in a home or office. The PC 10 is connected to the wall pad 102 to set whether to participate in a DR event or to establish a connection state of the electrical appliance 20. Play a role.

The smart outlet 104 is a power control device having a general electrical outlet, a short range wireless communication interface, an output voltage adjusting means, and the like, and controls power consumption according to a setting content of a DR event. The electrical outlet 20 used in the home or office is connected to the smart outlet 104. The electrical appliance 20 mentioned in the present invention includes all general household appliances or office supplies such as TVs, refrigerators, washing machines, air conditioners, and lighting. May be included.

The DR event reduces power consumption by reducing or cutting off the power supplied through the smart outlet 104, and it is preferable to apply only to a device that can be used even if the power is reduced or cut off. Electric appliances 20 that can be used to some extent even when the power is partially reduced include lighting, air conditioners, and electric heaters. Washing machines, air conditioners, TVs, audio systems, and computers are used to completely reduce power consumption. Suitable for events Devices that should normally operate normally, such as refrigerators, should not participate in DR events.

The ISO 200 determines the execution of the DR event and informs the savings system 100 of the execution time, the method, and the like through the LA operator 300. Each home or office checks for known event information and decides whether to participate in the event.

Hereinafter, a detailed method of implementing an event and a participation process will be described with reference to the drawings.

Program Participation by Real-Time Selection of Users

First, the ISO 200 and the LA operator 300 enter into a contract for conducting a DR event, and the LA provider 300 recruits end users to participate in the event. To this end, the LA operator 300 advertises the event contents, participation method, incentive details, etc. to end-users through online and offline.

The terminal customer participates in the event while inputting his or her information to the LA provider 300 using the saving system 100 or the PC 10. 3 is a diagram illustrating a screen for inputting end-user information, name, ID, address, telephone number, and other identification information is entered, the LA operator 300 is the end-user's power usage information with the end user's consent This can be identified using the DB of ISO 200 or other organizations (such as KEPCO).

In general, the application to participate in the event will be made through the wall pad 102 installed at the end customer, but if the saving system 100 is not installed at the end customer, the PC of the LA operator 300 is provided through the PC 10. You will be able to log in and apply.

The LA operator 300 accesses the power load information of the end customer owned by KEPCO, checks the load information, and determines whether it is suitable as its customer. We then analyze the power consumption patterns of end-users and recommend the best DR events for the customer. End-users can choose the event that is most appropriate for them, but it is not necessary to select a program recommended by the LA operator 300.

End-users select and enter the DR events they will attend. 4 is a view illustrating a screen for selecting a demand response event by the end customer, and provides a button for selecting one of direct load control, load blocking / load reduction, emergency demand response, and automatic bidding program. Wall pad 102 is preferably to be able to press the selection button using the touch screen.

The end customer can select both direct load control and load shedding / load reduction programs at the same time.

When the end-user selects a program, after confirming that there is no error on the display of the wall pad 102, the event participation is confirmed.

Then, the ISO 200 or LA operator 300 visits the end customer and installs the reduction system 100. In order to install the reduction system 100, the smart outlet 104 should be installed where the load to participate in the event is installed. When the smart outlet 104 is installed, information on which electric appliance 20 is installed in which smart outlet 104 is installed.

5 is a layout view showing the installation state of the electrical appliance in the end water acceptor.

The screen of FIG. 5 is displayed on the wall pad 102 or the PC 10 screen, and is a screen displayed when the user sets the position and type of the electronic product 20 used by him, power consumption, and the like.

As shown in Figure 5, in order to control the power usage of the electrical appliance 20 to control the smart outlet 104 for supplying power to the electrical appliance 20, each smart outlet (104-1 ~) Record which electrical appliances 20-1 to 20-5 are used in 104-5) and set how you want to reduce power consumption.

On the screen of the wall pad 102 or the PC 10, a screen for setting power usage information is displayed. Information input through the input means of the wall pad 102 or the PC 10 is stored in the wall pad 102, and the location of the smart outlet 104 and the detailed information of the electrical appliance 20 are converted into image information. And stored.

The user first establishes the interior space by drawing a home or office structure. In order to draw the internal space, a drawing program (Windows Paint, Photoshop, etc.) generally used in the PC 10 may be used.

Next, select an appropriate type of icon (displaying an electrical appliance) from a menu displayed on the screen, and drag and drop the icon to a position corresponding to where the actual electrical appliances 20-1 to 20-5 are located. The internal structure drawn by the user is stored as an image file, and the icons placed by the user represent individual electrical appliances.

The setting is completed by recording the type of the selected electrical appliances 20-1 to 20-5, the power saving method, and the average power consumption.

Information on the amount of power used by each of the electrical appliances 20-1 to 20-5 while participating in the DR event is stored in the DB inside the wall pad 102. It is the reference data for judging whether the amount of power consumption has been reduced.

The DR event information transmitted from the ISO 200 is transmitted to the saving system 100 through the LA operator 300, and each smart outlet 104 adjusts the power output amount according to the event participation information stored by the user. Reduce usage

FIG. 6 is a diagram illustrating a screen for registering a load of electrical appliances to participate in a demand response event.

The end customer lists the load type and load for each electrical appliance 20 stored in the wall pad 102 and registers as a participating load. Load types can be divided into air conditioners, heaters, lights, and others, but other types may be added.

The sum of the participating loads is calculated automatically.

FIG. 7 is a diagram illustrating a screen for selecting selections of loads participating in an event. The total amount of loads selected for participation through the same process as in FIG. 6 is summed for each load type.

In addition, the LA operator 300 calculates and stores the sum of participating loads of the plurality of end users participating in the event, so as to identify the total amount of loads that the LA operator 300 can reduce in real time as shown in [Table 1].

Taking the above table as an example, Hong Gil-dong ① can reduce the load of up to 10kW when participating in the event, and Hong Gil-dong ② can be set to reduce the load of 7kW and Hong-gil-dong ③ by 15kW (target). will be.

This is a problem that can be entered arbitrarily because the decision is based on the information that the end-user accepts. In order to solve this problem, the average power consumption of the corresponding end customers over the past three years can be identified through KEPCO, and then the appropriate level of total power consumption data can be determined. In addition, predicting possible loads based on the confirmed data will make it impossible to obtain incentives by fraudulent methods.

FIG. 8 is a diagram illustrating a screen in which an LA operator registers its information in ISO. The LA operator 300 inputs the personal information to store the ISO 200 in order to participate in the event of the ISO 200. In this process, when the LA operator 300, which initially makes a contract with the ISO 200, inputs personal information only once, it can be used afterwards by automatically calling the stored information.

The difference between the contents of FIG. 8 and the contents shown in FIG. 3 is that information of the person in charge is input together. Since the LA operator 300 is generally selected by the person in charge of the management of the terminal customer separately, it can be efficiently managed by inputting them together.

Personal information input of the LA provider 300 will be made through its own system of the LA provider 300 irrespective of the saving system 100 installed in the terminal customer.

When the LA operator 300 fills in the personal information, the ISO 200 analyzes load information of the LA operator 300 through KEPCO.

The ISO 200 recommends an appropriate program by analyzing a load usage pattern of the LA service provider 300 participating in the event, and the LA service provider 300 selects a program according to a pattern suitable for itself.

On the other hand, Figure 9 is a diagram showing a screen that the ISO announces the implementation of the demand response event to LA operators.

The ISO 200 notifies the LA operator 300 of the execution of a DR event in a situation where it is necessary to reduce power demand. The situation that needs to reduce the power demand means that the power reserve ratio is below a certain level or the power consumption is rapidly increased by a certain degree or more. In addition, the event is expected to maximize the demand for electricity, so the event can be held even when preemptive measures are required.

The ISO 200 participates in the event by providing the LA operator 300 with information such as the type of program (direct load control, load blocking / load reduction, demand response in case of emergency, automatic bidding, etc.), event name, start time and end time. Induce. It also provides information on the target load reduction and the resulting incentives or penalties.

FIG. 10 is a view showing a screen for the LA operator to announce the demand response event implementation contents to the end customer, the LA operator 300 receiving the event implementation notification from the ISO (200) also to the end customer reduction system 100 Announce the same.

The name of the event that the LA operator 300 announces may be attached separately by the LA operator 300, and incentives and penalties to be imposed on the end user may also be set according to its own criteria. However, it is desirable that the other information (start time and end time of the event, target load reduction amount) cannot be changed.

Then, the event notice is displayed on the end pad wall pad 102, the user is free to determine whether to participate in the event. The user determines whether to participate in consideration of a known event execution time, load reduction amount, and incentive size.

However, participation is determined differently according to the type of event. In other words, in the case of the direct load control program, the load is automatically reduced at the event start time even when the end customer does not have final confirmation, and the load is recovered again at the end time.

That is, if the user of the terminal customer first inputs to participate in the direct load control program, the amount of power output through the smart outlet 104 is always present while the direct load control program is executed, unless there is any change in the information. Decreases. This will be applied only to electrical appliances that do not have a big problem even if the power consumption is reduced for a certain period of time since the end user can automatically participate in the program without having to express his / her intention every time.

The wall pad 102 is directly controlled by the ISO 200 or the LA operator 300 to reduce the load.

On the other hand, if the end user is initially set up to participate in load interruption / load reduction or emergency demand response program, the user's participation should be checked whenever the event program is executed.

That is, when the event is announced through the wall pad 102 and the user finally confirms the participation in the event by using the input means, the power usage amount through the smart outlet 104 is reduced for a predetermined time. Therefore, the user may refuse to participate in the event when the power must be normally used.

In the direct load control program, a forced load reduction occurs, so incentives for the load reduction amount are paid, but it is preferable not to impose a penalty in case the target reduction amount is not met.

However, the load cut / load reduction or emergency demand response program can aim at the appropriate amount of load reduction according to the user's judgment and must make an effort to do this.

In addition, KEPCO or ISO (200) should secure a proper power reserve by participating a number of end users when the maximum power demand has occurred or is expected to occur, to accurately identify and reduce the information of end users to participate in the event. Accurately predicting loads will prevent power emergencies. Therefore, by imposing some penalties on the end-users who interfered with the prediction of the load reduction amount, it is possible to set a feasible goal and to achieve predictable power management.

FIG. 11 is a diagram illustrating a screen for notifying incentive details to be paid to terminal customers. FIG.

After the event is over, the ISO 200 calculates the incentive or penalty according to the load reduction amount to the LA operator 300, and the LA operator 300 again sends it to the user through the end user's wall pad 102. Notice.

As shown in Figure 11, by providing the event name and the event notification information (start time, end time, load reduction amount, etc.) to the user can be clearly understood how the result of the event participation.

Finally, ISO 200 or LA operator 300 will pay incentives or impose penalties on end-users. Payment of incentives may be by direct cash payments, or by reductions in electricity usage fees for end-users participating in the event. And this payment method also allows the user to choose.

Automated Bidding Program

The above description relates to a method of calculating and paying an incentive or penalty according to a ratio (for example, 100 won per watt cut) specified by the ISO 200 or the LA operator 300. However, automated bidding programs allow users to determine incentives or penalties.

In other words, the user sets a condition to participate in a program in advance and stores it, and the program is automatically executed when a situation that meets these conditions occurs. In addition, it is possible to maximize the profit of the power supply by selecting a user who presents the most favorable conditions from the viewpoint of the ISO 200 or LA operator 300 among the various users as the event participants.

First, end-users choose to participate in the automatic bidding program (see Figure 4).

Then, after the detailed personal information is input, the user directly selects an appropriate incentive size on the incentive input screen as shown in FIG. Information on the selected incentive is transmitted to the ISO 200 or LA provider 300.

If you maximize the incentive per kW you input, you will receive at least a lot of incentives for load reduction. You will not be able to maximize it unconditionally.

In addition, end-users, which have a lot of load reductions, can gain a lot by increasing the incentive per kW cumulatively toward the top.

For example, load reduction amounts from 0 to 10 kW at 400 won per kW, 10 kW to 20 kW at 500 won per kW, and 20 kW to 30 kW at 800 won. By doing so, the user can make incentives smaller than other competitors at lower cuts to favor bidding, and at higher cuts, incentives can be made larger to generate more profit.

The ISO 200 or the LA operator 300 selects a bidder that presents the smallest incentive among the plurality of terminal users based on the input incentive information. However, there is a disadvantage in that the amount of the incentive presented is large when selecting a successful bidder, and the cost of the ISO 200 or LA 300 operator is high. You can even choose to win.

When the automatic bidding setting is completed through the above process, the process of inputting personal information and identifying the load is performed as described above.

FIG. 13 is a view showing a screen in which an LA operator notifies the end customer of conducting a demand response event. According to the automatic bidding contents, the user who inputs the smallest amount is determined as the event participant, and the load reduction and the incentive or penalty are charged as described above.

Meanwhile, FIG. 14 is a diagram illustrating a screen in which an LA operator determines an incentive margin rate and a penalty.

The incentives that ISO 200 notifies LA operator 300 include the margin of ISO 200. The LA operator 300 earns revenue by having some of the incentives provided by the ISO 200 set to its margin. The margin earned by the Los Angeles operator 300 is limited to the incentives provided by ISO (200), and the margin is paid to the end-user.

Referring to FIG. 14, when the incentive amount that ISO 200 notifies the LA operator 300 in the direct load control program is 1,000 won per kW, the LA operator 300 sets its margin to 10%. Won revenue will be generated, and the remaining payees will be paid the remaining 900 won.

In addition, in the case of a load blocking / load reduction program, if 13% of the incentives announced by the ISO 200 is set as a margin, 130 won is the profit of the LA operator 300, and the remaining 870 won is paid to the terminal customer.

As such, the LA operator 300 may select an appropriate margin rate and present it to the end user, thereby increasing program participation and maximizing their profits.

Through this process, terminal prisoners can participate in various events, and as a result, receive incentives.

15 to 17 are screens for determining incentives, FIG. 15 is a screen for determining incentives to be paid to terminal customers according to the results of the direct load control program, and FIG. 16 is for end users according to the results of the load interruption program. FIG. 17 is a diagram illustrating a screen for determining an incentive to pay according to the result of the automatic bidding program, and FIG. 17.
