DIN EN IEC 61970-452:2024-03

This document is one of the IEC 61970-450 to 499 series that, taken as a whole, defines at an abstract level the content and exchange mechanisms used for data transmitted between control centres and/or control centre components, such as power systems applications. The purpose of this document is to define the subset of classes, class attributes, and roles from the CIM necessary to execute state estimation and power flow applications. The North American Electric Reliability Council (NERC) Data Exchange Working Group (DEWG) Common Power System Modelling group (CPSM) produced the original data requirements. These requirements are based on prior industry practices for exchanging power system model data for use primarily in planning studies. However, the list of required data has been extended starting with the first edition of this standard to facilitate a model exchange that includes parameters common to breaker-oriented applications. Where necessary this document establishes conventions with which an XML data file shall comply in order to be considered valid for exchange of models. The standard differs from DIN EN 61970-452:2019-09 as follows: a) the classes PowerElectronicsConnection, PowerElectronicsUnit, and PowerElectronicsWindUnit have been added to the Core Equipment Profile. This document is intended for two distinct audiences, data producers and data recipients, and may be read from two perspectives. From the standpoint of model export software used by a data producer, the document describes a minimum subset of CIM classes, attributes, and associations that shall be present in an XML formatted data file for model exchange. However, this standard does not prescribe how the network is modelled. It only stipulates what classes, attributes, and associations are to be used to describe the source model as it exists.
