IEC 61970

from Wikipedia, the free encyclopedia

The IEC 61970 (Energy management system application program interface (EMS-API)) of the International Electrotechnical Commission (IEC) describes a programming interface (Application Programming Interface, API) for energy management systems (EMS). The series of standards is still in progress.

An important part of the series of standards is the Common Information Model (CIM) - which is often confused with the Common Information Model of the Distribution Management Task Force (DMTF). The IEC CIM models objects and data exchange formats for the transmission, distribution and generation of electrical energy as well as between trading platforms and is standardized as a UML model. The CIM is the basis for other standardization projects of the IEC (IEC 61968). Harmonization with the IEC 61850 standard could in future enable consistent modeling and data exchange from the primary technology substation to telecontrol technology and network control technology to all applications in energy management systems.
