1 is a flowchart illustrating an integrated energy service control method using smart grid interoperability according to an embodiment of the present invention.

Referring to FIG. 1, in an integrated energy service control method using Smart Grid interoperability according to an embodiment of the present invention, Internet addresses can be allocated to a plurality of application service servers (S110).

At this time, Internet addresses corresponding to the Anycast address can be assigned. Since the advanced metering infrastructure (AMI) network and the Internet are constructed with IPv4 or IPv6 network, in order to provide the same Internet access method to a plurality of application service servers irrespective of the location or location, an ancast address is allocated and connected according to their functions .

At this time, the plurality of application service servers may include application service servers corresponding to at least one of power, gas, water and sewage, traffic, U-health, safety, and security. Through this, it is possible to construct an integrated infrastructure by linking sensors and meters for various services as well as smart grid based on electric power energy to operation management system. If the infrastructure is set up separately for each service sector, waste due to redundant investment can become very serious. It also solves problems such as mutual requirements and service continuity that may arise to jointly build various services.

Also, an integrated energy service control method using Smart Grid interoperability according to an embodiment of the present invention sets any one of Internet addresses as a destination address of meter data based on a service type of a smart meter device, The data can be forwarded to a communication device corresponding to any one of a data concentrator (DCU) and a user energy management system (EMS) (S120).

At this time, the smart meter device stores the internet address of the application service server corresponding to the service type of the smart meter device among the plurality of application service servers, and when the meter data is received, the Internet address of the application service server corresponding to the service type Destination address. For example, if the service type of the smart meter device is a gas application service, the Internet address of the gas application service server among the plurality of application service servers is stored, and the Internet address of the gas application service server is set as the destination address of the meter data . Thereby, meter data related to the gas measurement information can be transmitted to the gas application service server to perform energy service control.

At this time, the communication apparatus can allocate the Internet address of the application service server corresponding to the service function of each communication apparatus among the plurality of application service servers to the forwarding destination address of the forwarding data. For example, if the destination address of the meta data is not included in the plurality of application service servers, it may not be determined which application service server among the plurality of application service servers should forward the meta data. In this case, the service function of each communication device can be confirmed, and the Internet address of the application service server corresponding to the service function of each communication device among the plurality of application service servers can be set as the forwarding destination address.

At this time, the smart meter device can measure meter data corresponding to a plurality of application service servers. For example, the smart meter device can measure power information corresponding to a power application service server, gas information corresponding to a gas application service server, and the like.

In addition, the integrated energy service control method using smart grid interoperability according to an embodiment of the present invention is a method in which a communication device receives Internet addresses, compares Internet addresses and destination addresses, The meter data can be forwarded to the application service server (S130). For example, when comparing the Internet addresses and the destination address, if the destination address is the same as the Internet address of the power application service server among the Internet addresses, the meter data can be forwarded to the power application service server.

At this time, if the destination address is not included in the Internet addresses, the Meter data can be forwarded based on the application service type of the interface included in the communication device. For example, the data concentrator and user energy management system corresponding to the communication device may include a communication I / F convergence unit. The communication I / F convergence unit can function to perform forwarding by setting an internet address of a pre-set application service server at a destination address to which the communication device, that is, the data concentrator or the user energy management system, transmits the meta data. At this time, the internet address of the application service server set in advance may be determined to be one of the internet addresses of the plurality of application service servers according to the service function of the data concentrator or the user energy management system.

At this time, if the communication device is a data concentrator, the meter data can be forwarded using an Advanced Metering Infrastructure (AMI) network, and if the communication device is a user energy management system, the meter data can be forwarded using the Internet have.

Also, in the integrated energy service control method using the smart grid interoperability according to an embodiment of the present invention, the application service server corresponding to the destination address can perform integrated energy service control (S140). For example, the application service server can grasp the status of current application services based on meter data received from the smart meter device. At this time, a system that can manage and control services integrally by controlling the services based on the status of the services constituting the smart city by receiving metric data of various services by each application service server Can be provided.

By defining interfaces that utilize interoperability to take advantage of advanced metering infrastructures built on the Smart Grid, such as integrated energy service control, cities such as gas services, water and sewer services, transportation, medical, safety and security It is possible to implement a model that can smartly manage the existing infrastructures that constitute the infrastructure. The larger the size of a city and the more services it offers to provide a variety of services, the greater the economic and efficiency effects of such a model.
