The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical 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 technical 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 Organization 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 committee 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 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 and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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 or 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, use 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 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 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 possibility 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 61968-2, which is a technical specification, has been prepared by IEC technical committee 57: Power system control and associated communications. 3002:286916 ST CEI 3 DD IEC TS 619682:2003 3 Licensed Copy: London South Bank University, London South Bank University, Tue Dec 12 04:23:03 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 4 TS 91686-2 CEI:0230(E) The text of this technical specification is based on the following documents: Enquiry draft Report on voting 57/547/CDV 57/633/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table.

Intra-application integration is aimed at programs in the same application system, usually communicating with each other using middleware that is embedded in their underlying runtime environment, and tends to be optimized for close, real-time, synchronous connections and interactive request/reply or conversation communication models. IEC 61968, by contrast, is intended to support the inter- application integration of a utility enterprise that needs to connect disparate applications that are already built or new (legacy or purchased applications), each supported by dissimilar runtime environments. Therefore, IEC 61968 is relevant to loosely coupled applications with more heterogeneity in languages, operating systems, protocols and management tools. IEC 61968 is intended to support applications that need to exchange data on an event driven basis. IEC 61968 is intended to be implemented with middleware services that broker messages among applications, and will complement, but not replace utility data warehouses, database gateways, and operational stores. The series of standards will be using a lot of definitions, terms and abbreviations from the area of distribution management as well as from the area of Information and Communication Technology. This glossary part defines the terms and abbreviations as they are used in the context of this series of standards. The contents of this part 2 contains the following clauses. Table 1 Document overview for IEC 61968-2 Clause Title Purpose 1 Scope The scope, purpose, aim, and organization of IEC 61968 are described. 2 Terms and definitions Definition of terms that are specific to this series of standards or may have different interpretations when not defined explicitly. 3 Glossary of abbreviations Definitions of abbreviations that are specific to this series of standards. 3002:286916 ST CEI 5 DD IEC TS 619682:2003 5 Licensed Copy: London South Bank University, London South Bank University, Tue Dec 12 04:23:03 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 6 TS 91686-2 CEI:0230(E) APPLICATION INTEGRATION AT ELECTRIC UTILITIES SYSTEM INTERFACES FOR DISTRIBUTION MANAGEMENT Part 2: Glossary 1 Scope This glossary, accompanying the IEC 61968 series, is the second part in the series that, taken as a whole, define interfaces for the major elements of an interface architecture for Distribution Management Systems (DMS). This part of IEC 61968, referred to as Part 2, identifies and explains terms and abbreviations used in the remaining parts of IEC 61968. As used in IEC 61968, a DMS consists of various distributed application components for the utility to manage electrical distribution networks. These capabilities include monitoring and control of equipment for power delivery, management processes to ensure system reliability, voltage management, demand-side management, outage management, work management, automated mapping and facilities management. 2 Terms and definitions For the purposes of the IEC 61968 series, the following terms and definitions apply. 2.1 abstract component smallest logical block of software considered in the IEC 61968 interface reference model. Abstract components have interfaces that will be defined in future parts 3 to 10 of the IEC 61968 series. It is expected that different vendors will supply physical Application Components that support the interfaces for one or more abstract components 2.2 adapter layer of software that connects one component, for example an application, to another component, for example an interface implementation or a middleware implementation NOTE Same as object adapter. 2.3 address/network connection linkage of customer to premise to electrical feeder 2.4 application component block of software with specific functions and interfaces. A distribution management system is considered to be a set of one or more applications. Each application consists of one or more application components 2.5 attribute identifiable association between an object and a value. An attribute is a property of an object 2.6 audit trail information saved in a sequential form so that an event can be traced back to its origin 3002:286916 ST CEI 6 DD IEC TS 619682:2003 6 Licensed Copy: London South Bank University, London South Bank University, Tue Dec 12 04:23:03 GMT+00:00 2006, Uncontrolled Copy, (c) BSI TS 91686-2 IE:C2003(E) 7 2.7 automated mapping/geofacilities geospatial management system utilizing computer graphics technology to enter, store, and update graphic and non-graphic information. Automated mapping reduces the cost and effort in map creation and maintenance and facility record keeping. An automated mapping/ geospatial system processes geographic depictions and related non-graphic data elements for each entity stored in a digital database. The graphic representations are referenced using a coordinate system that relates to locations on the surface of the earth. Information in the database can be queried and displayed based upon either the graphic or non-graphic attributes of the entities. The system provides the utility a single, continuous electronic map of the service territory 2.8 automatic generation control controls generation such that average hourly generation control follows predispatch schedule. Generation levels may be changed based on improving economic operation, emergency conditions, or other improved conditions 2.9 billing system
