IEC 62325-451-2:2014 specifies a UML package for the scheduling business process and its associated document contextual models, assembly models and XML schemas for use within the European style electricity markets. This International Standard is based on the European style market contextual model (IEC 62325-351). The relevant aggregate core components (ACCs) defined in IEC 62325-351 have been contextualised into aggregated business information entities (ABIEs) to satisfy the requirements of the European style market scheduling business process. The contents of the corrigendum of August 2016 have been included in this copy.
