10、 ii Rec. ITU-T F.747.9 (03/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of I

11、TU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics

12、for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepare

13、d on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may c

14、ontain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to expr

15、ess requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Prope

16、rty Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of

17、intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

30、be strictly followed and from which no deviation is permitted if conformance to this Recommendation is to be claimed. The expression “is recommended“ indicates a requirement which is recommended but not absolutely required. Thus, this requirement need not be present to claim conformance. 6 Backgroun

31、d There are growing concerns about energy efficiency and emissions reduction among people from all aspects of life, which raises the demand for energy management for customers. With the development of information technology (e.g., Internet of things (IoT) ITU-T Y.4252), various smart objects, includ

32、ing sensors and actuators, can interconnect with one another to monitor and change the status of energy consumption equipment, which provides methods for energy management. Thus, user-side energy management service (EMS) is used to help consumers improve their energy efficiency as well as reduce the

33、ir energy costs. The user-side EMS provides raw data to users as well as processed information of energy consumption by collecting and monitoring energy consumption data from various equipment. It also makes energy-saving decisions based on multiple factors, such as user demands, suppliers pricing s

34、trategies, and optimization policies. Some other factors, such as government subsidies, device status and environmental conditions can also affect energy-saving decisions. For example, usage related information, such as the number of customers shopping in a mall, the occupancy rate of a hotel, the n

35、umber of students enrolled in a school, or attendance at a stadium, can affect energy-decisions, e.g., which lights and air conditioners need to be turned on/off. In recent years, various EMS systems have been developed and standardized. ITU-T Y.4252 describes requirements and capabilities for savin

36、g energy by using smart objects in home networks. The home energy management system (HEMS) ITU-T Y.4409 supports energy efficiency and reduction of energy consumption by monitoring and controlling devices. All these existing standards consider only smart objects which can be monitored and controlled

37、 automatically and remotely. However, not all existing energy-consumption devices are smart objects. They are not only different in the type of consumed energy (e.g., electricity, gas, coal), but also different in the capacity of metering and control. For example, in practice, an electricity meter c

38、an measure the amount of electric energy consumed by one circuit, which may be wired with multiple electrical equipment located in a home or in a factory. It can also be wired with individual electrical equipment. Thus, both coarse-grained and fine-grained data of consumed electric energy are collec

39、ted manually or through automatic meter reading (AMR). Also, many electrical devices can only be turned on and off manually, e.g., a light bulb with on-off switches. Some other electrical devices can be fine-tuned, e.g., temperature setting of an air conditioner. Furthermore, smart appliances can be

40、 controlled automatically and remotely. Considering the cost of adding metering units for individual energy consumption equipment and the difficulties of updating all traditional devices to smart objects, various heterogeneous devices with different capacities of metering and control must be support

41、ed in a practical user-side EMS system. In such an EMS system, energy consumption data for both single device and device group need to be collected, and these devices can be controlled by coarse-grained (on-off state) and fine-grained instructions. Furthermore, such operations are executed manually

42、or automatically. Rec. ITU-T F.747.9 (03/2017) 3 This Recommendation describes the requirements and scenarios of user-side EMS as well as the functional architecture for user-side EMS with heterogeneous devices. 7 General requirements for user-side EMS Several basic requirements of user-side EMS are

43、 given, including device management, data acquisition, policies management, energy consumption analysis, and decisions implementation. 7.1 Requirements for device management DM-01: The user-side EMS is required to register and deregister energy-consumption devices, metering devices and controlling d

44、evices. DM-02: The user-side EMS is required to maintain attribute information of energy-consumption devices, meter devices and control devices. DM-03: The user-side EMS is required to associate the energy-consumption devices with the corresponding metering device(s) and control device(s). 7.2 Requi

45、rements for data acquisition DA-01: The user-side EMS is required to collect and store the energy consumption data for each energy consuming device or device group. DA-02: The user-side EMS is required to provide the raw data as well as pre-processed data for further energy consumption calculation,

46、optimization, and device control. DA-03: The user-side EMS is required to support at least one kind of mechanism (i.e., manual or automatic) of metering data collection. DA-04: The user-side EMS is recommended to implement a metering adaptation layer which supports various data collection mechanisms

47、, such as remote and manual meter reading. DA-05: The user-side EMS is recommended to include the consumption of electricity, natural gas, wood, coal, gasoline, diesel and other energy resources as energy consumption data, if applicable. DA-06: The user-side EMS is recommended to collect environment

48、al data periodically. 7.3 Requirements for policies management PM-01: The user-side EMS is recommended to fetch and store energy consumption demands and optimization policies of users. PM-02: The user-side EMS is recommended to fetch and store the pricing policies of supply side. 7.4 Requirements fo

49、r energy consumption analysis EA-01: The user-side EMS is required to process the collected energy consumption data and provide the statistical energy consumption report to the user and the supplier if required. EA-02: The user-side EMS is recommended to provide an energy efficiency evaluation. For domestic users and public buildings, this evaluation is based on the amount of energy used, the number of people, and the environmental conditions. For a factory, the evaluation takes the amount of production into consideration. EA-03:
