Energy Market

ISO/IEC TR 15067-3-8:2020 (E), which is a Technical Report, provides a conceptual framework for developing architectures and designing solutions related to transactive energy (TE). Transactive energy allows electricity generated locally by consumers using wind, solar, storage, etc., at homes or buildings to be sold into a competitive market. This document provides guidance for enhancing interoperability among distributed energy resources involved in energy management systems at homes and buildings. It addresses gaps identified as problematic for the industry by providing definitions of terms, architectural principles and guidelines, and other descriptive elements that present a common ground for all interested parties to discuss and advance TE.
This document builds upon ISO/IEC 15067-3, with technology to accommodate a market for buying and selling electricity generated centrally or locally by consumers. The energy management agent (EMA) specified in ISO/IEC 15067-3 can represent the customer as a participant in TE. Transactive energy is important for achieving electric grid stability as power from renewable sources such as wind and solar fluctuates with time and weather.

IEC TS 62325-504:2015(E) defines the services needed to support the electronic data interchanges between different actors on the European Energy Market for Electricity (EME) in a fast (near-real-time), and secure way. At the same time, this Technical Specification can also be applied to integration problems outside the scope of IEC 62325-451, such as to the integration of gas market systems or general enterprise integration. Web Services (in WSDL) will be specified for the defined services, applying the Basic Web Service Pattern implementation profile from IEC 61968-100. The services needed to support the electronic data interchange on the European Energy Market for Electricity are:
- List Messages;
- Get Message;
- Put Message.

IEC SRD 62913-2-2:2019(E) initiates and illustrates the IEC’s systems approach based on Use Cases and involving the identification of generic smart grid requirements for further standardization work for market related domains, based on the methods and tools developed in IEC SRD 62913-1.
It captures possible “common and repeated usage” of a smart grid system, under the format of “Use Cases” with a view to feeding further standardization activities. Use Cases can be described in different ways and can represent competing alternatives. From there, this document derives the common requirements to be considered by these further standardization activities in terms of interfaces between actors interacting with the given system.
To this end, Use Case implementations are given for information purposes only. The interface requirements to be considered for later standardization activities are summarized (typically information pieces, communication services and specific non-functional requirements: performance level, security specification, etc.).

IEC 62325-451-7:2021 specifies a UML package for the electricity balancing business process and its associated document contextual models, assembly models and XML schemas for use within the European style electricity markets.
This part of IEC 62325 is based on the European style market contextual model (IEC 62325-351). The business process covered by this part of IEC 62325 is described in Clause 5.
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. Note this document contains code components.

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:
Addition of a new model allowing to publish information about the transmission capacity allocation participants.
Updates allowing to publish information about implicit transmission allocations on third countries borders, to publish outage related to consumption units and to publish information for resource object that can either consume or generate.

IEC 62325-451-4:2017 specifies a package for the settlement and reconciliation business process and the associated document contextual model, assembly model and XML schema for use within European style markets. 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 this business process. The contextualised ABIEs have been assembled into the relevant document contextual models. Related assembly models and XML schema for the exchange of information between market participants are automatically generated from the assembled document contextual models.
This part of IEC 62325 provides a uniform layout for the transmission of aggregated data in order to settle the electricity market. It is however not the purpose of this document to define the formula to be taken into account to settle or reconcile a market. The purpose of this document is only to enable the information exchange necessary to carry out the computation of settlement and reconciliation.
The settlement process or reconciliation process is the way to compute the final position of each market participant as well as its imbalance amounts.
This new edition includes the following significant technical changes with respect to the previous edition:
- removal of the attributes “quantity” and “secondary quantity” of the class “Point”;
- introduction of the classes “Quantity” and "Reason" from IEC 62351-351 UML package.

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.

The relevant aggregate core components (ACCs) defined in IEC 62325-351 have been contextualized into aggregated business information entities (ABIEs) to satisfy the requirements of the European style market acknowledgment business process. The contextualized ABIEs have been assembled into the acknowledgment document contextual model. This new edition includes the following significant technical changes with respect to the previous edition:
- addition of an optional attribute ProcessType to the acknowledgement document to ease routing of incoming acknowledgement document instances to the appropriate application;
- clarification of the activity diagram for the acknowledgement process;
- addition of the list of constraints on datatypes.
