IEC 61970-452 Ed. 2.0 en:2015

IEC 61970-452:2015(E) rigorously defines the subset of classes, class attributes, and roles from the CIM necessary to execute state estimation and power flow applications. These requirements are based on prior industry practices for exchanging power system model data for use primarily in planning studies. This standard is intended for two distinct audiences, data producers and data recipients, and may be used from these two perspectives.
