IEC 62325-451-6:2018 specifies a UML package for the market information publication business process and its associated document contextual models, assembly models and XML schemas for use within the European-style electricity markets. This 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 publication business process.
This new edition includes the following significant technical changes with respect to the previous edition:
