Specification for information exchange of power demand response 1 Scope This standard specifies the general principles and requirements of information exchange, information model, information exchange service and information exchange mechanism of power demand response system. This standard is applicable to the design, development and upgrade of power demand response system. 2 Normative references The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 32672-2016 General technical specification of power demand response system GB/T 7408-2005 Data elements and interchange formats - Information interchange - Representation of dates and times Decree No.14 of the National Development and Reform Commission of the People's Republic of China - Regulations on security protection of power monitoring systems 3 Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 32672-2016 and the following apply. For the convenience of application, some terms and definitions specified in GB/T 32672-2016 are listed below. 3.1 information model describing the main objects involved in demand response businesses, which are mainly composed of information class and its association relation 3.2 information exchange service information model encapsulated via specified data encapsulation mode and transmitted between systems, system and end in the demand response system 3.3 information exchange information flows of different systems or ends organize information according to a unified information model and exchange information through information exchange services 3.4 information class composed of a set of properties that describe the characteristics of objects and represent specific objects in demand response businesses 3.5 association relation representing the mutual relation between different information classes, including association, dependence, generalization, aggregation, etc. 3.6 package composed of a set of information classes of the same type and their association relation 3.7 data type type used to describe an property in an information class 3.8 demand response business organizer demand response service manager who organizes and implements the demand response business relying on the demand response service system; it may also refers to the demand response aggregator that implements the demand response business for the demand response service manager or the superior demand response aggregator based on the demand response aggregation system. 3.9 demand response business participant power users and demand response aggregators who directly participate in the demand response business organized by the demand response service manager, or power users and demand response aggregators who participate in the demand response business organized by the demand response aggregators 3.10 demand response event describing the information such as power price, load reduction or transfer volume according to certain rules during the execution of demand response business, and the information shall be released by the implementation organization to power users 3.11 up node; UN code used to represent the system or end participating in information exchange in the demand response system. Compared with the down node, it usually refers to the demand response service system and demand response aggregation system 3.12 down node; DN code used to represent the system or end participating in information exchange in the demand response system. Compared with the up node, it usually refers to the demand response aggregation system and demand response end 4 General principles and requirements of information exchange 4.1 General principles Legality, normalization, security, authenticity, reliability, validity, timeliness. 4.2 Legality requirements Ensure the legitimacy of users participating in information exchange during the implementation of demand response business, so as to ensure the legitimacy of information exchange. 4.3 Normalization requirements The essential feature of information exchange is normalization, which is an important premise for information exchange to carry out and realize information resource sharing and exchange in different countries and regions, different industries and different enterprises. 4.4 Security requirements Including confidentiality, integrity, non-repudiation and authentication of information exchange, which is in accordance with Decree No.14 of the National Development and Reform Commission of the People's Republic of China. 4.5 Authenticity requirements Various information data shall truthfully reflect the real situation during the implementation of the demand response business.
