23、or an energy management system (EMS). This standard is based to a large extent upon the work of the EPRI Control Center API (CCAPI) research project (RP-3654-1). The principle objectives of the EPRI CCAPI project are to: reduce the cost and time needed to add new applications to an EMS or other syst
24、em1; protect the investment in existing applications that are working effectively; improve the capability to exchange information between disparate systems both within and external to the control center environment. The technical approach is to provide an integration framework for interconnecting ex
25、isting applications/systems that is based on a common architecture and information model; independent of the underlying technology. The principal task of the IEC 61970 series of standards is to develop a set of guidelines and standards to facilitate 1) the integration of applications developed by di
26、fferent suppliers in the control center environment2and 2) the exchange of information to systems external to the control center environment. The scope of these specifications includes other transmission systems as well as distribution and generation systems external to the control center that need
27、to exchange real-time operational data with the control center. Therefore, another related goal of these standards is to enable the integration of existing legacy systems as well as new systems built to conform to these standards in these application domains. The complete set of standards includes t
28、he following parts: Part 1: Guidelines and general requirements Part 2: Glossary Part 3XX: Common Information Model (CIM) Part 4XX: Component Interface Specification (CIS) Part 5XX: CIS Technology Mappings IEC 61970-1 provides a set of guidelines and general infrastructure capabilities needed for th
29、e application of the EMS-API interface standards. It describes the reference model that provides the framework for the application of the other parts of the EMS-API standards. This reference model is based on a component architecture, which places the focus of the standards on component interfaces f
30、or information exchange between applications in a control center environment. The model is also applicable to similar information exchanges between control center applications and systems external to the control center environment, such as other control centers, Independent System Operators (ISOs),
31、Regional Transmission Organizations (RTOs), and Distribution Management Systems (DMS). IEC 61970-1 also includes general capabilities for the integration infrastructure, which while not part of this standard, is expected to provide certain essential services to support the EMS-API interface standard
32、s. _ 1Ideally, an application should be installed on a system with minimal effort and no modification of source code; i.e., the way software packages are installed on a desktop computer. The EMS-API Project goal is to at least approach that ideal by reducing the often significant efforts currently r
33、equired to install third-party applications in an EMS. 2The control center environment includes traditional transmission control within a utility as well as the newer Independent System Operators (ISOs) and Regional Transmission Operators (RTOs), which are not affiliated with any one utility.

Thi
35、s part of the IEC 61970 series describes typical integration scenarios where these standards are to be applied and the types of applications to be integrated. A reference model is defined to provide a framework for the application of the other parts of these EMS-API standards. This reference model i
36、s based on a component architecture that places the focus of the standards on component interfaces for information exchange between applications in a control center environment. While the primary objective of the EMS-API is to support the integration of applications within the control center, the re
37、ference model is also applicable to information exchanges between control center applications and systems external to the control center environment, such as other control centers, ISOs, RTOs, and distribution systems. This standard describes the role of the other parts of the standard, including th
38、e Common Information Model (CIM) in the IEC 61970-3XX series, the Component Interface Specifications (CIS) in the IEC 61970-4XX series, and Technology Mappings in the IEC 61970-5XX series. This part of the IEC 61970 series also includes general capabilities that are needed by the integration infrast
39、ructure to facilitate the exchange of information via the component interfaces specified by the CIS. While the integration infrastructure itself is not part of this standard, it is expected to provide certain essential services to support the EMS-API interface standards. These services are enumerate
40、d in Clause 6. This part of the IEC 61970 series does not specify individual implementations or products, nor does it constrain the representation of information within a computer system application. This standard specifies the externally visible interfaces, including semantics and syntax, required
41、to support the interoperability of products supplied by different vendors. 2 Normative References The following referenced documents are indispensable for the application of this document.

The guidelines created for
44、this area (or portions thereof) apply to several different integration scenarios. This work recognizes that existing systems with their unique interfaces will need to evolve to use the interfaces specified in this work. The following different types of integration situations are envisaged. While the
45、se are typical scenarios, they are only a subset of the possible examples. a) Integration of applications developed by different suppliers into one homogenous system: In this scenario, independently developed application components (such as an Optimal Power Flow (OPF) are integrated into a system (w
46、hich includes supporting infrastructure). This allows the system integrator to more easily integrate an individual component into any system, whether it is an existing system or a newly developed system. b) On-line data exchange between separate systems: The control center needs to communicate with
47、other, separate systems within the corporation and between enterprises. Loosely coupled integration schemes are needed to exchange information. Examples include information exchanges with a DMS, the corporate accounting system, or another EMS. Enterprise integration scenarios generally fit into this
48、 category. c) Integration of separate systems sharing some engineering data: This corresponds to the situation where application packages from different vendors use partly overlapping engineering modeling data (such as the impedance of a line segment). d) Exchange of serialized data between the same
49、 applications in different systems: Limited integration can be achieved by using file transfer techniques. An agreed upon format is used for this type of export/import exchange. The use of File Transport Protocol (FTP) and an eXtensible Markup Language (XML)-based format file (or document) for the exchange of power sysem models is an example of this scenario. e) Developing a new application in a homogenous system: This corresponds to vendors or utilities developing new applications for integra
