*The purpose of this part is describing the definitions, terms, requirements, system architecture and use cases(in the Appendix) as the basis for the other parts of PC118/WG1 TR. The main content of Part1 includes TR mapRequirementsActorsSystem architecture and Interface Description.

*This technical report can be divided into 3 hierarchical layers. The top layer can be sub sectioned to general provision, information model, information exchange model, etc.; the second layer can be sub sectioned to overview, requirement, architecture and interface, etc. According to the urgency of standardization need, the prior action plan of the TR is not suggested to discuss here.

*This part regulates the requirements of architecture design and modeling construction for Smart Grid user interface, including requirements of function, communication, performance, security, install configure, maintenance, etc. for example, in which, Italic parts are proposed by U.S. in its Framing Paper

*This part regulates the requirements of architecture design and modeling construction for Smart Grid user interface, including requirements of function, communication, performance, security, install configure, maintenance, etc. for example, in which, Italic parts are proposed by U.S. in its Framing Paper

*This part identifies the actors involved in the system, main types including organization, person, system, equipment, etc., and describes the responsibilities or functionalities of the actors. In order to clarify the information need to be exchanged between grid and custormer, the actors are divided into two groups.*For instance characteristics, controllability, and adjustability of the equipment.*This sub-clause describes the nature of the smart grid user interface and the hierarchical communication relationships between different actors.Grid side actors includes distribution energy management system, transmission energy management system, AMI enterprise system, etc.; user side actors includes various smart equipment and energy management system.

*On user side, in the absence of the energy management system, communication gateway (e.g. smart meter) can also realize the monitoring and management on user side equipment. The exchange between grid and user side smart equipment can conduct as an indirect exchange, through the centralized coordination of customer energy management system, or as an direct exchange without the centralized coordination of customer energy management system. The later way is suitable for the control of large load/power source/energy storage which has a higher requirement on real-time, as well as the ancillary service involving large user.Besides, following requirements and characteristics should be taken into consideration for the smart grid user interfacearchitecture:1Architectural Consideration for a User Interface (U.S.)The user interface must be suitable for interaction with many different kinds of users with varying local abilities and constraints. The control and automation technology used to respond to the grid communication will vary with the type of user (residential, commercial, industrial) and the smart grid user interface must work with all of them. It is also important that changes in the control technologies found in the users facility not break the interface. These control technologies will evolve on independent time schedules. This means that architecture for the interface must be based on a specific communication exchanges that do not depend on the details of how the user implements a response. Because of the possibility of aggregation of users, a single entity (the aggregator) may look like a user to the grid but at the same time look like the grid to one of the aggregated users. The architecture must accommodate this type of hierarchical structure.2Communication PathThe grid may exchange information with users by three main ways: smart meter (using AMI network), communication gateway (using Internet or other public network), or exclusive gateway (using exclusive network without exchange with smart meter).3Control Mode The control modes of industrial, commercial, and residential customer side smart equipment will be supported: local autonomous control of equipment, centralized coordination by customer energy management system, and direct control by grid side.

*This section presents the description and taxonomy of the existing standards from the perspective of standard-setting, objectives of standards, etc. thus we can fully integrate the two approaches of Top-down and Bottom-up to accelerate the development of PC118/WG1 TR, and further identify the standard gap, based on PC118 SBP.

*The logic relationship between the 6 parts of TR is presented in the following Diagram. The first part of the TR needs to analyze the various applications and functions exchanged between grid side and customer side, in which, Demand Response is a key application. According to the top-down approach, the defined WG1 requirements need to be consistent to WG2 use cases.6DR top-downapproach ,WG1PC118 WG2

*Use cases of user interface by countries are listed in this Appendix A, which are applicable to one or more types in residential, commercial, industrial users. Smart grid user interface and the model will support a wide range of energy management applications and electrical service provider interactions, including: applications and electrical service provider interactions, including: (proposed in the first plenaryPC118/WG1 meeting in Tianjin)

**Various systems are developed independently by manufactures, each have their own internal data structure and communication. Therefore, information exchange are needed to realize the various applications, while the existing standard only defined the internal information model of various system.Through a defined common model, applications can realize information exchange by accessing the common date of system, and no longer depend on the internal information expression of system.

Realize interoperability and compatbility between various systems, and has no concerns to specific applications.
