| Demand Response (DR), as one of the core technologies of smart grid, can fully tap the potential of the load in power grid control, and improve system reliability and the ability of accommodating intermittent. To carry out the interactive modeling of demand response can promote the standardization process, which is of great significance to promote large-scale demand response.First of all, introduce the advantages of smart grid compared to traditional power grid a, and the technical obstacles of demand response which is one of the most important applications of smart grid technology in the process of application and popularization. Combined with the current situation of the development of automated demand response technology in China, prove the importance of establishing demand response model for interactive information from the perspective of information integrationSecondly, summarize the current typical demand response service, analyse the functional requirements of business processes, and extracte the functional requirements. Using UML modeling tool of EA to analyse use case of peak electricity price, real-time price and interruptible load, demand side bidding and demand response service assessment requirements, and refine the information interactive content.Then, analyse the main function of information model of each package from the CIM standard, find out packages associated with demand response business. Comparison of demand response business information exchange content, to establish interactive information model of demand response according to the principle of expanding common information model.Finally, establish the frame structure of the service-oriented demand response system. Using demand response evaluation as an example to explain the application method of information model in demand response system based on model driven integration as the theoretical basis and the WebServices platform for the support. |
