Wall pad for power consumption control {WALLPAD FOR CONTROLLING ELECTRIC POWER CONSUMPTION}

The present invention relates to a wall pad for power consumption control, and more particularly, to a wall pad for power consumption control to control the power consumption as needed by adjusting the use state of electrical appliances connected to the outlet of a home or office. .

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 is a limit that simple promotions and campaigns without special rewards or incentives cannot achieve their intended purpose.

In order to suppress the power demand, payback events are carried out, and in order to compensate for the power savings caused by the event, the amount of power used and the amount of power saved within a specific building must be identified. This data collection is not possible.

To this end, install smart outlets equipped with communication modules and power control switches in the building, control power consumption by controlling each smart outlet, and total power consumption of the building by combining the power consumption transmitted from each smart outlet. Measures should be taken.

However, even if you control the power consumption by using a smart outlet, if you do not know which electrical appliances are connected to each outlet, it is impossible to select the appropriate control method and the amount of savings, which leads to a burden on the electrical appliances, thereby reducing participation. There was a problem.

The present invention for solving the above problems is connected to the smart outlet and short-range wireless communication can control the power usage pattern while collecting the power consumption, connected to a general PC in the home or office to graphically display the state of use of electrical appliances An object of the present invention is to provide a wall pad for controlling power consumption.

In addition, an object of the present invention is to provide a wall pad for power consumption control using the Android platform-based OS as a basic operating system that can be smoothly run in a small system with low power consumption.

The present invention devised to solve the above problems is a control device used in the HEMS (100) to reduce the power consumption by adjusting the power supplied to the electrical appliance through a smart outlet, Android platform-based OS (102a) and ; An API 102b used for communication between an operating system and an application program; A power usage control unit 102c which grasps the installation state of the electrical appliance 20 and adjusts the amount of power output through the smart outlet 104; An installation information DB 102d for storing information on the type of electric appliance 20, power consumption, and whether to participate in a DR event; A power consumption DB 102e for storing information on the amount of power used by the electrical appliance 20; Gateway 102f for transmitting and receiving data by connecting to the PC 10 or the smart outlet 104 through a wired or wireless communication network.

The power-saving payback event of the present invention measures the power consumed by participating in an event and the power consumed by the electrical appliance 20 using a home energy management system (HEMS) 100 installed in a home or office, and based on this. In a way that determines incentives or penalties.

The payback 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.

The ISO 200 serves as a payback event, a demand response (DR) event, and an HEMS 100 installation for end customers.

The ISO 200 includes a Demand Response Automation Server (DRAS), which transmits DR events to the HEMS 100 through the LA provider 300 when the DR service provider (ISO) operates the DR service. 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 HEMS 100 in the terminal consumer. In addition, the DRMS receives the end user's load information from the HEMS 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 HEMS 100 within the terminal customer.

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 HEMS 100 needs to be installed in the end customer. The HEMS 100 includes a wall pad 102 and a plurality of smart outlets 104.

The wall pad 102 included in the HEMS 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 HEMS 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.
