12、 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 issuing Recommendations on

13、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 topics. The approval of IT

14、U-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 publication, the expression “Administration“ is used

15、for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the publica

16、tion 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 publication is required of any party. INT

24、upplement on security functional architecture for smart grid services using telecommunication networks 1 Scope This Supplement defines a security functional architecture for smart grid (SG) services using telecommunication networks. The following issues are specified in this Supplement: security ris

25、ks of smart grid services using telecommunication networks; security requirements for smart grid services using telecommunication networks; security functional architecture for smart grid services using telecommunication networks based on a smart grid functional model. 2 References None. 3 Definitio

26、ns 3.1 Terms defined elsewhere This Supplement uses the following terms defined elsewhere: 3.1.1 access control b-ITU-T X.1252: A procedure used to determine if an entity should be granted access to resources, facilities, services, or information based on pre-established rules and specific rights or

27、 authority associated with the requesting party. 3.1.2 data integrity b-ITU-T X.800: The property that data has not been altered or destroyed in an unauthorized manner. 3.1.3 privacy b-ITU-T X.1252: The right of individuals to control or influence what personal information related to them may be col

28、lected and managed, retained, accessed, and used or distributed. 3.1.4 advanced metering infrastructure (AMI) b-ITU-T G.9902: The primary means for utilities to interact with meters on customer sites. In addition to basic meter reading, AMI provides two-way communication which allows energy usage da

29、ta to be collected and analysed and it enables the interaction with advanced devices such as electricity meters, gas meters, heat meters, and water meters, through various communications media. 3.1.5 home area network (HAN) b-ITU-T G.9959: A network capable of connecting devices in home premises. 3.

30、2 Terms defined in this Supplement This Supplement defines the following terms: 3.2.1 demand response (DR): A smart grid feature that allows consumers to reduce or change their electrical use patterns during peak demand, usually in exchange for a financial incentive. Demand response provides mechani

31、sms and incentives for utility, 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 to optimize the balance of power supply and demand. 3.2.2 distributed energy resources (DER): Energy generat

32、ion and energy storage facilities located at the customer premises or at power transmission and distribution systems. 2 X series Supplement 26 (03/2016) 3.2.3 electric vehicle supply equipment (EVSE): Equipment that charges a vehicular electric battery by direct current or an alternating current pow

33、er source. 3.2.4 energy management system (EMS): A computer system comprising a software platform providing basic support services and a set of applications providing the functionality needed for the effective operation of electrical generation and transmission facilities so as to ensure adequate se

34、curity of the energy supply at a minimum cost. 3.2.5 intelligent electronic device (IED): A term used in the electric power industry to describe microprocessor-based controllers of power system equipment, such as circuit breakers, transformers and capacitor banks. 3.2.6 regional transmission organiz

35、ation (RTO): An independent organization (profit or non-profit) established for the purpose of operating the transmission assets and providing wholesale transmission services within a defined (usually multi-state) geographic region. Typically, an RTO does not itself own the transmission facilities,

36、but instead operates them on behalf of the transmission-owning utilities. 3.2.7 remote terminal unit (RTU): A microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or a supervisory control and data acquisition (SCADA) system by tran

37、smitting the telemetry data to the system or altering the state of connected objects based on control messages received from the system. 3.2.8 smart grid (SG): A two-way electric power delivery network connected to an information and control network through sensors and control devices. The smart gri

38、d supports the intelligent and efficient optimization of the power network. 3.2.9 smart meter: A device in the premises to monitor and control the electrical power usage of home devices based on demand response (see clause 3.2.1) information from home devices. 3.2.10 supervisory control and data acq

39、uisition (SCADA): A computer system that monitors an industrial, infrastructure or facility-based control process. 4 Abbreviations and acronyms This Supplement uses the following abbreviations and acronyms: AMI Advanced Metering Infrastructure CE Central Equipment CEMS Customer Energy Management Sys

44、n this Supplement, R indicates a risk. The digit on the right side of R is an indication of the security risk (e.g., R1). Thus, a security level (i.e., 1, 2, 3) refers to the classification in this Supplement. One of the notation examples in this Supplement is as follows: R1-2 indicates the security

45、 risk categorization of data disclosure for the moderate security level case. In this Supplement, SR indicates a security requirement. 6 Reference architecture and smart grid services This clause introduces the reference architecture of smart grids of clause 6.2 of b-ITU-T Smart-O-33 and explains ho

46、w smart grid services are treated in this Supplement. The relationship between the reference architecture of smart grids and smart grid services is also discussed in this clause. 4 X series Supplement 26 (03/2016) The reference architecture of smart grids is defined in b-ITU-T Smart-O-33 and explain

47、ed in Appendix I. The reference architecture of smart grids in b-ITU-T Smart-O-33 is related to a domain perspective, whereas this Supplement focuses on a service perspective. The smart grid provides various services based on information and communication technology (ICT). These smart grid services

48、cover common users of demand response (DR) and electric vehicles (EVs) as well as services for controlling the power grid, such as distribution grid management and wide-area power system monitoring. Such coverage is well beyond the services of the traditional power grid. The major service domains of

49、 the smart grid are specified in b-NIST IR 7628 as described in clauses 6.1 to 6.6. 6.1 Smart meter infrastructure Smart metering infrastructure is an advanced metering infrastructure (AMI) with bidirectional communications between provider and customer, which enables DR service and distributed energy resources service. It is called advanced metering infrastructure in b-NIST IR 7628. 6.2 Demand response and consumer energy efficiency Demand response (DR) is an active way of ass
