a storage unit that stores a plurality of data models respectively corresponding to the communication protocols to store the data in each of the plurality of data models; and a processing unit that generates a basic data model by performing data modeling according to any one of the communication protocols, generates one or more extended data models by performing data modeling according to the rest of the communication protocols, includes the extended data models in the basic data model, and stores the included extended data models in the storage unit. ## Claims ### Claim 1 A data collection apparatus of a power system that manages a plurality of sites using different communication protocols, the data collection apparatus comprising: a communication unit that communicates with the plurality of sites to receive data on energy use information from the plurality of sites; a storage unit that stores a plurality of data models corresponding to the communication protocols, respectively, to store the data in the plurality of data models, respectively; and a processing unit that performs data modeling according to any one of the communication protocols to generate a basic data model, and performs data modeling according the other communication protocols to generate one or more extended data models so as to allow the extended data models to be included in the basic data model and stored in the storage unit; wherein the processing unit is configured to: generate the basic data model, store the data inside of the basic data model, generate the one or more extended data model, corresponding to each of the other communication protocols, store the one or more extended data models inside of the basic data model, map the data stored inside of the basic data model to each of the one or more extended data model, thereby producing mapped data corresponding to each of the one or more extended data models, and store each of the mapped data inside of each of the one or more extended data models, wherein the data stored inside of the basic data model are stored separately from a plurality of extended data models stored inside of the basic data model. ### Claim 2 (depends on 1) The data collection apparatus of claim 1, wherein each of the plurality of sites uses any one of OPC UA (Open Platform Communications Unified Architecture), RESTful API, MODBUS, and DNP protocols. ### Claim 3 (depends on 2) The data collection apparatus of claim 2, wherein the basic data model is a model according to the OPC UA protocol. ### Claim 4 (depends on 2) The data collection apparatus of claim 2, wherein the extended data model is a model according to any one of the RESTful API, MODBUS, and DNP protocols. ### Claim 5 (depends on 1) The data collection apparatus of claim 1, wherein the communication unit performs communication according to the communication protocol based on the plurality of data models. ### Claim 6 (depends on 1) The data collection apparatus of claim 1, wherein the processing unit processes data stored in the plurality of data models according to whether the communication unit transmits and receives data. ### Claim 7 (depends on 1) The data collection apparatus of claim 1, wherein the processing unit links data stored in the basic data model with data stored in the extended data model. ### Claim 8 (depends on 7) The data collection apparatus of claim 7, wherein when the data stored in the basic data model is changed, the processing unit changes the data stored in the extended data model in response to the data change of the basic data model. ### Claim 9 (depends on 7) The data collection apparatus of claim 7, wherein when the data stored in the extended data model is changed, the processing unit changes the data stored in the basic data model in response to the data change of the extended data model.
