IEC 62325-351:2016

Overview

IEC 62325-351:2016, titled Framework for energy market communications - Part 351: CIM European market model exchange profile, is an international standard developed by the International Electrotechnical Commission (IEC). This edition focuses on European style electricity markets and specifies a UML package that provides a structured logical view of functional aspects required for market management. The package is grounded in the Common Information Model (CIM), a standardized methodology for modeling electrical systems and markets.

This standard facilitates consistent exchange and interoperability of market data by defining a European market profile that reflects recent European regulations and business developments. By adopting the CIM-based approach, IEC 62325-351 supports efficient energy market communications crucial for transparency, regulatory compliance, and operational efficiency across European electricity markets.

Key Topics

• Common Information Model (CIM) Application
  The standard leverages the CIM framework to create a detailed European market exchange profile, enabling uniform representation of market data and processes.

• European Market Model Package Structure
  It details the UML package necessary for market management systems, including new classes and associations to accommodate emergent business rules and market mechanisms aligned with European regulations.

• Business Process Modelling
  IEC 62325-351 specifies how market processes should be modeled at the logical level, ensuring clarity in implementation and supporting automation of key market functions.

• Data Exchange Profiles
  Defines profiles for electronic market documents, time series data, tariff types, market participants, and auction processes to standardize communication and data interoperability.

• Time Series and Quantity Coding
  Provides methodologies for coding time, quantities, and flow directions within time series, ensuring harmonized interpretation of market data over specified intervals.

• Compliance with European Regulations
  Enhancements in this edition reflect the latest European Union energy market regulations, ensuring that market participants and operators can readily comply with legal frameworks.

Applications

• Energy Market Management Systems
  IEC 62325-351 guides the development of software systems managing European style electricity markets by defining classes and interactions needed for activities such as bidding, auctions, and scheduling.

• Market Data Exchange
  Facilitates interoperability among market operators, grid operators, and participants by standardizing the format and semantics of market communications.

• Regulatory Reporting
  helps systematize data reporting processes to statutory authorities in compliance with European regulatory requirements.

• System Integration
  Enables integration of heterogeneous energy management systems across borders through common data models, supporting pan-European market harmonization.

• Vendor Software Development
  Provides a reference model for software vendors developing tools for energy trading, settlement, and market monitoring specific to European markets.

Related Standards

• IEC 62325 Series
  This part (351) is within the broader IEC 62325 framework that addresses the Framework for energy market communications, tackling various aspects like message formats, profiles, and market data exchange.

• Common Information Model (CIM) Standards
  IEC 62325-351 builds upon CIM standards (IEC 61970 and IEC 61968), which provide foundational models for electrical power systems and distribution management.

• European Regulations on Electricity Markets
  Aligns with EU directives and regulations such as the Clean Energy Package, REMIT (Regulation on Wholesale Energy Market Integrity and Transparency), and network codes impacting market operations.

• IEC 62325-450
  Relates to the overall modelling framework for energy markets, of which the European market profile is a component.
