Also, the terms "part," " module, "and the like described in the specification mean units for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software .

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view illustrating a configuration of a Smart Grid-based smart home system according to an embodiment of the present invention.

Referring to FIG. 1, a Smart Grid-based smart home system according to an embodiment of the present invention includes an operation domain 10, a service provider domain 20, a customer domain 30 and a distributed energy resource (DER) domain 40.

The operating domain 10 is responsible for the overall operation of the smart grid to provide and manage the power provided by the transmission domain to the customer domain 30 and includes an Energy Management System (EMS) And a meter data management system (MDMS) actor 11.

The energy management system actor 13 functions to control the generation and transmission of electric power corresponding to the user's electric power demand. For example, the energy management system actor 13 can perform the function of preventing the power wastage by grasping the power demand and distributing the power according to the grasped power demand.

The meter data management system actor 11 collects and stores meter information from the customer domain 30, provides the collected meter information to the related organizations, and uses the log information of the meter operator 37 to perform data verification and use authentication . For example, the meter data management system actor 11 preliminarily collects meter information including energy usage, energy production, and the like from the meter controller 37 of the customer domain 30, In the event of a problem, the original data can be analyzed and the function of supporting the problem solving can be performed.

The service provider domain 20 functions to provide power services to the customer domain 30 that substantially performs communication in the smart home system and includes a customer information system (CIS) 21, A Billing Actor 23 and a Home Manager Actor 25.

The customer information system actor 21 is a system for managing personal information of a customer. In the smart home system, data including a user's personal privacy among data generated by a user using a smart home appliance is leaked due to various events .

The billing agent 23 performs the billing function of the customer such as billing and billing of the customer including billing and payment processing. For example, the Billing Actor 23 prevents the power information generated when a customer uses power from a smart home appliance in a smart home system to be manipulated by hacking caused by an external or internal event to cause monetary damage Can be performed.

The home manager actor 25 installs equipment interacting between the customer domain 30 and the smart grid and performs energy management functions. For example, the home manager < RTI ID = 0.0 > actor 25 < / RTI > can perform functions such as maintenance of a communication network or various equipment for connecting a smart home system and a smart grid to prevent facility deterioration and increase safety from external threats.

The customer domain 30 includes a customer equipment 31, a customer EMS operator 33, an energy service interface (ESI) operator 35 and a meter operator (37).

The customer equipment controller 31 may include, for example, a terminal, a cable modem, and the like, which are devices existing in a smart home connected to the service provider domain 20 through a communication network. The customer equipment actor 31 can recognize this problem in real time in the event of a problem due to an event during bidirectional communication with the smart device in the smart home.

The customer energy management system actor 33 displays the customer's power usage and performs monitoring and control functions for meter information, remote control, and distributed energy support. For example, when the customer energy management system actor 33 detects a problem through real-time monitoring, it can perform a key role in problem solving by performing an audit and log function in order to solve the problem and to maintain security. It can be a necessary action required.

The energy service interface actor 35 is an interface for communicating with an actor in an external domain. For example, the energy service interface actor 35 may provide bidirectional communication between an actor in the customer domain 30 and an actor in the external domain to inform and quickly recover when a threat occurs in the smart home system .

The meter operator 37 functions to provide the measured power usage information in the customer domain 30. For example, the meter operator 37 may be a Smart Grid AMI (Automatic Metering Infrastructure), associated with the Billing Actor 23 of the service provider domain 20, and may be compared with the customer's raw data in the event of a hack May be necessary to minimize various damage situations.

The distributed energy resource domain 40 includes an Energy Services Interface (ESS)

The energy storage system actor 41 is a system for controlling the charging and discharging of the energy storage device. When a user uses a smart home appliance in a smart home system, the power supply is blocked due to an attack of an external and / or internal hacker or a disaster. The emergency power can be supplied as an emergency situation.

The smart grid-based smart home system according to an embodiment of the present invention includes a field area network (FAN) 100, a premise network 200, and a home area network (HAN) 300).

The field area network 100 communicates the operations of the operating domain 10, the service provider domain 20, the customer domain 30, and the distributed energy resource domain 40. In particular, the field area network 100 communicates with the actor of the operating domain 10 and the actor of the customer domain 30. For example, the field area network 100 may be capable of communicatively connecting devices capable of controlling breakers or transformers.

The on-premises network 200 is in the customer domain 30 and communicates all the activities existing in the customer domain 30 with each other. Accordingly, all the actors existing in the customer domain 30 can perform real-time bidirectional communication with each other. Therefore, if a problem occurs in the smart electronic device or the internal communication network in the smart home system, the users of the customer domain 30 can communicate with each other through the on-premises network 200 in order to inform the other domain.

The home area network 300 exists in the customer domain 30 and communicates between the smart meter existing in the home of the smart home environment and the smart home appliances and the smart home appliances existing in the home of the smart home environment.
