11、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 ITU. ITU-T is responsible for studying technical, operating and tariff questions and i
12、ssuing 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 for study by the ITU-T study groups which, in turn, produce Recommendations on these
13、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 prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the express
14、ion “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 contain certain mandatory provisions (to ensure, e.g., interoperability or applicabili
15、ty) 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 express requirements. The use of such words does not suggest that compliance with the Rec
16、ommendation 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 Property Right. ITU takes no position concerning the evidence, validity or applicability o
17、f 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 received notice of intellectual property, protected by patents, which may be required to implement this Reco

30、ommendation uses the following terms defined elsewhere: 3.1.1 aggregator b-ITU-T FG-Smart: A system in smart grid for collecting the energy generated by residences and micro grids. 3.1.2 building automation system (BAS) b-ITU-T FG-Smart: A system capable of computerized monitoring and control of a b
31、uildings lighting and mechanical systems, and monitoring for performance and potential failure. 3.1.3 customer b-ITU-T FG-Smart: The end user of energy or services, who may also generate, store, and manage the energy. Traditionally, three customer types are discussed, each with its own domain: resid
32、ential, commercial and industrial. 3.1.4 customer information system (CIS) b-ITU-T FG-Smart: A software application for handling customer calls, billing, and related operations. 2 Rec. ITU-T Y.2071 (09/2015) 3.1.5 data collector b-ITU-T FG-Smart: A distributed processing device that has supervisory

34、tive. Mechanisms and incentives for utilities, business, industrial, and residential customers to cut energy use during times of peak demand or when power reliability is at risk. Demand response is necessary for optimizing the balance of power supply and demand. 3.1.7 distributed energy resources (D
35、ER) b-ITU-T FG-Smart: Energy generation and energy storage facilities located at the customer premises, or power transmission and distribution systems. 3.1.8 energy management system (EMS) b-ITU-T FG-Smart: A computer system comprising a software platform providing basic support services and a set o

37、tions and functions required for smart grid applications to control and manage the smart grid services in the customer premises. 3.1.10 energy storage b-ITU-T FG-Smart: Energy storage provides storage functions of electricity using various types of batteries. NOTE One example usage of energy storage
38、 is used to respond effectively to a dynamic price mechanism from a utility network. The electric energy is stored in the storage during a relatively lower price period, while the stored electric energy may replace the higher price of electric power from the utility network. 3.1.11 meter data manage
39、ment system (MDMS) b-ITU-T FG-Smart: Meter data management (MDM) refers to a key component in the smart grid infrastructure that is in the process of being evolved and adopted by utility companies. An MDM system (MDMS) performs long term data storage and management for the vast quantities of data th
40、at are now being delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head end servers that manage the data collection in advanced metering infrastructure (AMI) or automatic meter reading systems. An MDMS will typically import the data
41、, then validate, cleanse and process it before making it available for billing and analysis. The more flexible the MDM application, the better it is able to integrate to existing enterprise applications and help to streamline utility business processes. Benefits can be seen in billing, customer serv
42、ice, outage management and analysis of utility operations. 3.1.12 sensor b-ITU-T FG-Smart: Sensors are a significant component of the electrical grid; sensors are used in several ways: temperature monitoring, security, providing data for peak demand adjustment. They are integral components of a smar
43、t grid. 3.1.13 service provider b-ITU-T FG-Smart: An organization providing smart grid related services to electrical customers and utilities. 3.1.14 smart grid b-ITU-T FG-Smart: The “Smart Grid“ is a two way electric power delivery network connected to an information and control network through sen
44、sors and control devices. This supports the intelligent and efficient optimization of the power network. 3.1.15 smart meter b-ITU-T FG-Smart: Smart meter is a premise device to monitor and control electrical power usage of home devices based on “Demand Response (DR) information“ from home devices. B
45、ut, it is not recommended that the smart meter controls directly per each premise appliance because of the private security policy. To control and manage each premise appliance, it is required for a home management system such as a home gateway and a home server to support the control and management

ITU-T Y.2071 (09/2015) 3 3.1.16 substation b-ITU-T FG-Smart: The site where equipment for switching or regulating electrical voltage is located. 3.1.17 supervisory control and data acquisition (SCADA) b-ITU-T FG-Smart: A computer system that monitors an industrial, infrastructure, or facility
47、-based control process. 3.1.18 utility provider b-ITU-T FG-Smart: An organization that provides electric power, gas and water. In smart grid, a utility company supplies electric power. 3.2 Terms defined in this Recommendation This Recommendation defines the following term: 3.2.1 micro energy grid (M
