scope:

1.1 Scope of full standard The IEC 61968 standard, taken as a whole, defines interfaces for the major elements of interface architecture for Distribution Management Systems (DMS). Part 1: Interface Architecture and General Requirements, identifies and establishes requirements for standard interfaces based on an Interface Reference Model (IRM). Parts 3-10 of this standard define interfaces relevant to each of the major business functions described by the Interface Reference Model. 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, meter reading, meter control and facilities management. This set of standards is limited to the definition of interfaces and is implementation independent. It provides for interoperability among different computer systems, platforms, and programming languages. Methods and technologies used to implement functionality conforming to these interfaces are considered outside of the scope of these standards; only the interface itself is specified in these standards. 1.2 Scope of this part of IEC 61968 The Common Information Model (CIM) is an abstract model of the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of software applications developed independently by different vendors. The CIM facilitates integration by defining a common language (i.e., semantics and syntax) based on the CIM to enable these applications or systems to access public data and exchange information independent of how such information is represented internally. The IEC Standard 61970-301 defines a core CIM for Energy Management System (EMS) applications, including many classes that would be useful in a wider variety of applications. Due to its size, the CIM classes are grouped into logical Packages, and collections of these packages are maintained as separate International Standards. This document extends the core CIM with packages that focus on Distribution Management Systems (DMS) including Assets, Work, Customers, Load Control, Metering, and others. Another IEC Standard 61970-302 extends the CIM with packages that focus on Financial, Energy Scheduling, Reservation, and other market-related applications. Other CIM extensions may be published as International Standards, each maintained by a separate group of domain experts. Depending on a project's needs, the integration of applications may require classes and packages from one or more of the CIM standards. The CIM with Distribution extensions (DCIM) is defined as IEC Standard 61970-301, plus this document. Other parts of the 61968 standards will define profiles and message schemas to support use of the DCIM in specific domain areas, such as metering or distribution power system model exchange.
