14、) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrica
15、l and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technica
16、l committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organiza
17、tion for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical co
18、mmittee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications
19、 is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national an
20、d regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services a
21、nd, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants o
22、r agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, us
23、e of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that
24、some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may
25、propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possi
26、bility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62746-3, which is a technical specification, has been prepared by IEC technical committ
27、ee 57: Power systems management and associated information exchange. PD IEC/TS 62746-3:2015IEC TS 62746-3:2015 IEC 2015 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 57/1527/DTS 57/1610/RVC Full information on the voting for the approv
28、al of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62746 series, published under the general title Systems interface between customer
29、 energy management system and the power management system, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific pu
30、blication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publicatio
31、n indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. PD IEC/TS 62746-3:2015 6 IEC TS 62746-3:2015 IEC 2015 INTRODUCTION The purpose of this part of IEC 62746 is to defi
32、ne an architecture for IEC 62746 series of standards that can be leveraged for the management of customer energy resources and DER. These resources may be a combination of load, generation and storage resources that can be managed to respond to signals provided by grid and/or market operators. These
33、 resources may be identified and managed as individual resources with specific capabilities, or as virtual resources with an aggregated set of capabilities. The focus of this architecture is to leverage the Internet for communications between grid operators, market operators, distribution system ope
34、rators, electricity suppliers, aggregators, service providers and energy resources. This Technical Specification leverages existing IEC standards.The data model of IEC 62746 is based on the Common Information Model and IEC 61850. IEC 62746 is transport- independent. Figure 1 shows the relationship o
35、f IEC 62746 to other IEC and ISO standards.

36、which is a Technical Specification, establishes an architecture that is supportive of interfaces between the Customer Energy Management System and the Power Management System. A DER Management System can also be a Customer Energy Management System. 2 Normative references The following documents, in
