Energy management system application program interface (EMS-API) - Part 457: Dynamics profile (IEC 61970-457:2024)

IEC 61970-457:2024 specifies a standard interface for exchanging dynamic model information needed to support the analysis of the steady state stability (small-signal stability) and/or transient stability of a power system or parts of it. The schema(s) for expressing the dynamic model information are derived directly from the CIM, more specifically from IEC 61970-302.
The scope of this document includes only the dynamic model information that needs to be exchanged as part of a dynamic study, namely the type, description and parameters of each control equipment associated with a piece of power system equipment included in the steady state solution of a complete power system network model. Therefore, this profile is dependent upon other standard profiles for the equipment as specified in IEC 61970-452: CIM static transmission network model profiles, the topology, the steady state hypothesis and the steady state solution (as specified in IEC 61970-456: Solved power system state profiles) of the power system, which bounds the scope of the exchange. The profile information described by this document needs to be exchanged in conjunction with IEC 61970-452 and IEC 61970-456 profiles’ information to support the data requirements of transient analysis tools. IEC 61970-456 provides a detailed description of how different profile standards can be combined to form various types of power system network model exchanges.
This document supports the exchange of the following types of dynamic models:
• standard models: a simplified approach to exchange, where models are contained in predefined libraries of classes interconnected in a standard manner that represent dynamic behaviour of elements of the power system. The exchange only indicates the name of the model along with the attributes needed to describe its behaviour.
• proprietary user-defined models: an exchange that would provide users the ability to exchange the parameters of a model representing a vendor or user proprietary device where an explicit description of the model is not described in this document. The connections between the proprietary models and standard models are the same as described for the standard models exchange. Recipient of the data exchange will need to contact the sender for the behavioural details of the model.
This document builds on IEC 61970-302, CIM for dynamics which defines the descriptions of the standard dynamic models, their function block diagrams, and how they are interconnected and associated with the static network model. This type of model information is assumed to be pre-stored by all software applications hence it is not necessary to be exchanged in real-time or as part of a dynamics model exchange.
This second edition cancels and replaces the first edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The majority of issues detected in IEC 61970-302:2018 and fixed in IEC 61970-302:2022 led to update of this document;
b) IEEE 421.5-2016 on Excitation systems is fully covered;
c) IEEE turbine report from 2013 was considered and as a result a number of gas, steam and hydro turbines/governors are added;
d) IEC 61400-27-1:2020 on wind turbines is fully incorporated;
e) WECC Inverter-Based Resource (IBR) models, Hybrid STATCOM models and storage models are added;
f) The user defined models approach was enhanced in IEC 61970-302:2022 adding a model which enables modelling of a detailed dynamic model. This results in the creation of two additional pr

Interface de programmation d’application pour système de gestion d’énergie (EMS-API) - Partie 457: Profil de régimes dynamiques (IEC 61970-457:2024)

IEC 61970-457:2024 spécifie une interface normalisée pour l’échange des informations de modèles dynamiques, nécessaires pour soutenir l’analyse de la stabilité en régime établi (stabilité en petits signaux) et/ou la stabilité transitoire d’un système électrique ou des parties de celui ci. Le ou les schémas d’expression des informations de modèles dynamiques sont déduits directement du CIM, plus spécifiquement de l’IEC 61970-302.
Le domaine d’application du présent document inclut uniquement les informations des modèles dynamiques qu’il est nécessaire d’échanger comme partie intégrante d’une étude des régimes dynamiques, à savoir le type, la description et les paramètres de chaque équipement de commande associé à un équipement de système électrique inclus dans la solution permanente d’un modèle exhaustif de réseau électrique. Par conséquent, ce profil dépend des autres profils normalisés pour les équipements comme cela est spécifié dans l’IEC 61970-452: Profils du modèle de réseau de transport statique CIM, la topologie, l’hypothèse en régime établi et la solution en régime établi (comme cela est spécifié dans l'IEC 61970-456: Profils d'état de réseaux électriques résolus) du système électrique, ce qui limite la portée de l’échange. Il est nécessaire d’échanger les informations de profils décrites par le présent document conjointement avec les informations de profils spécifiées dans l’IEC 61970-452 et l’IEC 61970-456 afin de venir à l’appui des exigences relatives aux données des outils d’analyse transitoire. L’IEC 61970-456 donne une description détaillée du mode selon lequel les différentes normes de profils peuvent être combinées afin de former différents types d’échanges de modèles de réseaux électriques.
Le présent document soutient l’échange des types suivants de modèles dynamiques:
• modèles normalisés: une approche simplifiée d’échange, avec laquelle les modèles sont contenus dans des bibliothèques prédéfinies de classes interconnectées de manière normalisée, qui représentent le comportement dynamique des éléments du système électrique. L’échange indique uniquement le nom du modèle, ainsi que les attributs nécessaires pour décrire son comportement.
• modèles propriétaires définis par l'utilisateur: échange qui offre la possibilité aux utilisateurs d’échanger les paramètres d’un modèle qui représente le dispositif propriétaire d’un fournisseur ou d’un utilisateur, lorsque le présent document ne donne pas de description explicite du modèle. Les connexions entre les modèles propriétaires et les modèles normalisés sont les mêmes que celles décrites pour l’échange de modèles normalisés. Il est nécessaire que le destinataire de l’échange de données contacte l’émetteur afin d’obtenir les informations détaillées du comportement du modèle.
La structure du présent document suit le CIM pour régimes dynamiques de l’IEC 61970-302, qui définit les descriptions des modèles dynamiques normalisés et de leurs diagrammes de blocs fonctionnels, ainsi que leur mode d'interconnexion et d’association avec le modèle de réseau statique. Par hypothèse, ce type d’information de modèle est réputé être pré mémorisé par toutes les applications logicielles et il n’est ainsi pas nécessaire de l'échanger en temps réel ou comme partie intégrante d’un échange de modèles de régimes dynamiques
Cette seconde édition annule et remplace la première édition parue en 2021. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:

Aplikacijski programski vmesnik za sistem upravljanja z energijo (EMS-API) - 457. del: Dinamični profil (IEC 61970-457:2024)

Standard IEC 61970-457:2024 določa standardni vmesnik za izmenjavo informacij o dinamičnem modelu, potrebnih za podporo analize ustaljene stabilnosti (stabilnost majhnega signala) in/ali prehodne stabilnosti elektroenergetskega sistema ali njegovih delov. Shema oziroma sheme za izražanje informacij o dinamičnem modelu izhajajo neposredno iz skupnega informacijskega modela (CIM), natančneje iz standarda IEC 61970-302.
Področje uporabe tega dokumenta vključuje samo informacije o dinamičnem modelu, ki jih je treba izmenjati kot del dinamične študije, in sicer vrsto, opis in parametre krmilne opreme, povezane z delom opreme elektroenergetskega sistema, vključenega v ustaljeno rešitev celotnega modela omrežja elektroenergetskega sistema. Zato je ta profil odvisen od drugih standardnih profilov za opremo, kot je določeno v standardu IEC 61970-452: Profili CIM za statični model prenosnega omrežja, od topologije, ustaljene hipoteze in ustaljene rešitve (kot je določeno v standardu IEC 61970-456: Profili stanja sproščenega elektroenergetskega sistema) elektroenergetskega sistema, ki omejuje področje uporabe izmenjave. Informacije o profilu, opisane v tem dokumentu, je treba izmenjati v povezavi z informacijami o profilih iz standardov IEC 61970-452 in IEC 61970-456 za podporo podatkovnih zahtev orodij za prehodno analizo. Standard IEC 61970-456 podrobno opisuje, kako je mogoče z združitvijo različnih standardov za profile oblikovati različne vrste izmenjav modelov omrežja elektroenergetskega sistema.
Ta dokument podpira izmenjavo naslednjih vrst dinamičnih modelov:
• Standardni modeli: poenostavljen pristop k izmenjavi, pri katerem so modeli v predhodno določenih knjižnicah razredov, ki so med seboj povezane na standarden način in predstavljajo dinamično vedenje elementov elektroenergetskega sistema. Izmenjava vključuje samo ime modela skupaj z atributi, potrebnimi za opis njegovega vedenja.
• Lastniški uporabniško določeni modeli: izmenjava, ki omogoča uporabnikom določanje parametrov modela, ki predstavlja lastniško napravo prodajalca ali uporabnika, če v tem dokumentu model ni eksplicitno opisan. Povezave med lastniškimi in standardnimi modeli so enake, kot je opisano za izmenjavo standardnih modelov. Prejemnik izmenjave podatkov se mora za podrobnosti o vedenju modela obrniti na pošiljatelja.
Ta dokument temelji na standardu IEC 61970-302 – Skupni informacijski model (CIM) za dinamiko, ki vsebuje opise standardnih dinamičnih modelov, njihovih funkcijskih blokovnih diagramov ter način njihove medsebojne povezave in povezave s statičnim modelom omrežja. To vrsto informacij o modelu naj bi predhodno shranile vse programske aplikacije, zato jih ni treba izmenjati v realnem času ali kot del izmenjave dinamičnega modela.

Overview

SIST EN IEC 61970-457:2024 - Energy management system application program interface (EMS‑API) Part 457: Dynamics profile - defines a standard interface and UML/CIM schemas for exchanging the dynamic model information needed for power system dynamic studies (small‑signal and transient stability). The schema is derived from the Common Information Model (CIM) for dynamics (IEC 61970‑302). The document focuses on the type, description and parameters of control equipment associated with network equipment included in a solved steady‑state model.

Key technical topics and requirements

  • Scope and dependency: The dynamics profile is intended to be exchanged together with static transmission network profiles (IEC 61970‑452) and solved power system state profiles (IEC 61970‑456). The dynamic schemas build on CIM dynamics definitions in IEC 61970‑302.
  • Profile types: Provides multiple profile families for data exchange:
    • Dynamics profile (model types and parameter lists)
    • Detailed model configuration and parameterisation profiles
    • Simulation settings and simulation results profiles
  • Model exchange approaches:
    • Standard models: Reference to predefined model libraries (model name + parameters).
    • Proprietary / user‑defined models: Allows exchange of vendor/user custom models with parameter lists; recipients may need vendor documentation for behavioural details.
  • Supported dynamic model classes: Synchronous/asynchronous machines, excitation systems, turbine/governor models, PSS, STATCOM, SVC, HVDC, wind turbine models, inverter‑based resources (IBR), storage, protection and relay dynamics (as described in the standard).
  • Packaging & dependencies: Instance file distribution, dependency management and versioning rules for model exchanges.
  • Edition updates: This second edition updates mappings consistent with IEC 61970‑302:2022 and incorporates IEEE 421.5 (excitation systems), IEC 61400‑27‑1 (wind turbines), WECC IBR and hybrid STATCOM/storage models, and expanded turbine/governor coverage.

Practical applications and users

Who uses IEC 61970‑457:2024:

  • Transmission system operators and control centres for dynamic off‑line studies

Frequently Asked Questions

SIST EN IEC 61970-457:2024 is a standard published by the Slovenian Institute for Standardization (SIST). Its full title is "Energy management system application program interface (EMS-API) - Part 457: Dynamics profile (IEC 61970-457:2024)". This standard covers: IEC 61970-457:2024 specifies a standard interface for exchanging dynamic model information needed to support the analysis of the steady state stability (small-signal stability) and/or transient stability of a power system or parts of it. The schema(s) for expressing the dynamic model information are derived directly from the CIM, more specifically from IEC 61970-302. The scope of this document includes only the dynamic model information that needs to be exchanged as part of a dynamic study, namely the type, description and parameters of each control equipment associated with a piece of power system equipment included in the steady state solution of a complete power system network model. Therefore, this profile is dependent upon other standard profiles for the equipment as specified in IEC 61970-452: CIM static transmission network model profiles, the topology, the steady state hypothesis and the steady state solution (as specified in IEC 61970-456: Solved power system state profiles) of the power system, which bounds the scope of the exchange. The profile information described by this document needs to be exchanged in conjunction with IEC 61970-452 and IEC 61970-456 profiles’ information to support the data requirements of transient analysis tools. IEC 61970-456 provides a detailed description of how different profile standards can be combined to form various types of power system network model exchanges. This document supports the exchange of the following types of dynamic models: • standard models: a simplified approach to exchange, where models are contained in predefined libraries of classes interconnected in a standard manner that represent dynamic behaviour of elements of the power system. The exchange only indicates the name of the model along with the attributes needed to describe its behaviour. • proprietary user-defined models: an exchange that would provide users the ability to exchange the parameters of a model representing a vendor or user proprietary device where an explicit description of the model is not described in this document. The connections between the proprietary models and standard models are the same as described for the standard models exchange. Recipient of the data exchange will need to contact the sender for the behavioural details of the model. This document builds on IEC 61970-302, CIM for dynamics which defines the descriptions of the standard dynamic models, their function block diagrams, and how they are interconnected and associated with the static network model. This type of model information is assumed to be pre-stored by all software applications hence it is not necessary to be exchanged in real-time or as part of a dynamics model exchange. This second edition cancels and replaces the first edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The majority of issues detected in IEC 61970-302:2018 and fixed in IEC 61970-302:2022 led to update of this document; b) IEEE 421.5-2016 on Excitation systems is fully covered; c) IEEE turbine report from 2013 was considered and as a result a number of gas, steam and hydro turbines/governors are added; d) IEC 61400-27-1:2020 on wind turbines is fully incorporated; e) WECC Inverter-Based Resource (IBR) models, Hybrid STATCOM models and storage models are added; f) The user defined models approach was enhanced in IEC 61970-302:2022 adding a model which enables modelling of a detailed dynamic model.

SIST EN IEC 61970-457:2024 offers a comprehensive framework for the exchange of dynamic model information crucial for the analysis of power system stability, including small-signal and transient stability. The standard effectively identifies and clarifies the necessary elements of dynamic modeling within the energy management system application program interface (EMS-API), providing crucial guidance for organizations engaged in energy management. One of the key strengths of this standard lies in its reliance on the Common Information Model (CIM) as defined in IEC 61970-302. By deriving the schema for dynamic model information directly from CIM, the standard ensures that it is compatible with existing infrastructure and methodologies for power system analysis. This standardized interface enables seamless integration with other profiles, specifically IEC 61970-452 and IEC 61970-456, creating a cohesive framework for comprehensive power system dynamic studies. The document delineates two primary types of dynamic models: standard models and proprietary user-defined models. The inclusion of standard models facilitates a simplified exchange process, relying on predefined libraries of classes that represent various elements of a power system, thereby enhancing interoperability across different tools and platforms. This approach reduces complexity and promotes efficiency in data exchange. Moreover, the provision for proprietary user-defined models addresses the diverse needs of users implementing bespoke equipment configurations. By allowing for the exchange of parameters without requiring a comprehensive behavioral description within the document, it ensures that users can still convey intricate information while maintaining flexibility in using unique devices. The technical revisions in this new edition demonstrate the standard's commitment to continuous improvement. The incorporation of feedback from previous editions and integration of additional standards, such as IEEE 421.5-2016 and IEC 61400-27-1:2020, indicate a robust and responsive development process. The enhancements in the user-defined models approach allow for the modeling of complex dynamic behaviors, reflecting the evolving landscape of power system technologies, such as inverter-based resources and new turbine models. In summary, SIST EN IEC 61970-457:2024 is a significant update that builds on its predecessor, offering a clearer, more effective standard for dynamic model exchanges in power systems. Its relevance is heightened in today's context of increasing complexity in energy management, making it an essential tool for practitioners in the field. The standard provides a thorough understanding of how to effectively utilize dynamic modeling in support of power system analysis, ensuring that critical stability assessments can be conducted with accuracy and clarity.

SIST EN IEC 61970-457:2024は、エネルギー管理システムアプリケーションプログラムインターフェース(EMS-API)の一部として、動的モデル情報の標準インターフェースを定義しています。この標準は、電力システム又はその一部の定常状態安定性(小信号安定性)および過渡的安定性の分析を支援するために必要な情報の交換を可能にします。 この文書の範囲は、動的研究の一部として交換される必要がある動的モデル情報に限定されており、具体的には、完全な電力システムネットワークモデルの定常状態解に関連する各制御機器のタイプ、説明、およびパラメータが含まれます。このプロファイルは、IEC 61970-452およびIEC 61970-456によって指定された設備用の他の標準プロファイルに依存しており、これにより交換の範囲が制限されています。 この文書では、標準モデルとユーザー定義のモデルという2つの主要なタイプの動的モデルの交換をサポートしており、標準モデルは事前定義されたライブラリに containedされ、電力システムの要素の動的特性を標準的に表現するのに対し、ユーザー定義モデルはベンダーまたはユーザーの専有デバイスを表すモデルのパラメータを交換できることを特徴としています。このように、SIST EN IEC 61970-457:2024は、動的モデルの標準的かつ柔軟な交換を促進します。 技術的な改訂として、IEC 61970-302に基づき、標準動的モデルの説明や相互接続方法についての改善が含まれており、最新の技術基準に基づいた重要な変更が行われています。特に、IEEE規格や風力タービンに関する最新の知見が反映されており、動的モデルの詳細なモデリングが可能となるアプローチの強化も行われています。 この標準は、電力システムの動的分析ツールのデータ要件を満たすための情報交換をサポートし、異なるプロファイル標準を組み合わせて多様な電力システムネットワークモデルの交換を形成する方法についても詳細を提供しています。したがって、SIST EN IEC 61970-457:2024は、電力業界におけるエネルギー管理システムの動的情報の標準化を進める上で、極めて重要であると評価されます。

SIST EN IEC 61970-457:2024 표준은 전력 시스템의 정상 상태 안정성(소신호 안정성) 및/또는 과도 안정성 분석을 지원하기 위한 동적 모델 정보 교환을 위한 표준 인터페이스를 규정합니다. 이 표준의 범위는 전력 시스템 장비와 관련된 제어 장비의 유형, 설명 및 매개변수를 포함하여 동적 연구의 일환으로 교환해야 하는 동적 모델 정보에 국한됩니다. 해당 문서의 프로필 정보는 IEC 61970-452 및 IEC 61970-456 프로필 정보와 함께 교환되어야 하며, 이는 과도 분석 도구의 데이터 요구 사항을 지원하는 데 필수적입니다. 이 표준의 주요 강점 중 하나는 표준 모델과 사용자 정의 독점 모델을 모두 지원한다는 점입니다. 표준 모델은 전력 시스템의 동적 동작을 나타내는 클래스의 미리 정의된 라이브러리에 포함된 간소화된 접근 방식을 제공하며, 사용자 정의 모델은 공급업체 또는 사용자가 만든 장치의 매개변수를 교환할 수 있는 유연성을 제공합니다. 이로 인해 다양한 사용자 요구에 부합하며, 전력 시스템의 동적 특성을 효율적으로 관리할 수 있는 체계를 갖추고 있습니다. 문서에는 IEC 61970-302, CIM을 기반으로 한 동적 모델에 대한 명확한 설명이 포함되어 있어, 동적 모델과 정적 네트워크 모델 간의 연결성을 강화합니다. 이는 모든 소프트웨어 응용 프로그램이 이러한 모델 정보를 미리 저장하고 있을 것으로 가정하여, 실시간으로 교환할 필요가 없음을 보여줍니다. 이번 두 번째 판은 2021년에 발행된 첫 번째 판을 대체하며, 기술적 개정이 이루어졌습니다. 이전 판 대비 주요 기술적 변화로는 IEC 61970-302:2018의 문제를 해결하여 이 문서를 업데이트한 부분, IEEE 규격에 대한 완전한 수용, 그리고 다양한 새로운 가스, 증기 및 수력 터빈 모델의 추가가 포함됩니다. 이는 전력 시스템의 동적 모델 개발에 있어 최신 표준을 반영하고 있음을 나타냅니다. SIST EN IEC 61970-457:2024는 동적 모델 정보 교환의 필요성에 대한 통찰을 제공하며, 전력 시스템의 안정성과 효율성을 높이는 데 중요한 참고자료로 작용할 것입니다. 따라서 이 표준은 에너지 관리 시스템 응용 프로그램 인터페이스(EMS-API)의 발전에 중대한 기여를 하고 있습니다.

Die Norm SIST EN IEC 61970-457:2024 bietet eine umfassende Schnittstelle für den Austausch dynamischer Modellinformationen, die für die Analyse der stationären Stabilität und/oder transienten Stabilität von Stromsystemen notwendig sind. Der Geltungsbereich dieser Norm konzentriert sich auf dynamische Modellinformationen, die im Rahmen von dynamischen Studien ausgetauscht werden müssen, einschließlich Typ, Beschreibung und Parametern der Regelungseinrichtungen, die mit den Stromsystemkomponenten verbunden sind. Ein wesentlicher Vorteil dieser Norm liegt in der direkten Ableitung der Schemas für die dynamischen Modellinformationen aus dem Common Information Model (CIM), insbesondere aus der IEC 61970-302. Diese solide Grundlage gewährleistet die Interoperabilität der verschiedenen Softwareanwendungen im Energiemanagement, was für die Durchführung präziser Analysen von zentraler Bedeutung ist. Die Norm unterstützt den Austausch verschiedener Typen von dynamischen Modellen, darunter standardisierte Modelle sowie benutzerdefinierte proprietäre Modelle. Die standardisierten Modelle bieten einen vereinfachten Ansatz zum Austausch, bei dem die Modelle in vordefinierten Bibliotheken enthalten sind und somit das dynamische Verhalten von Elemente des Stromsystems effizient darstellen können. Im Gegensatz dazu ermöglichen die proprietären Modelle den Benutzern, spezifische Parameter auszutauschen, auch wenn eine explizite Beschreibung der Modelle nicht in der Norm enthalten ist. Ein weiterer Bedeutungsbereich dieser Norm liegt in der Abhängigkeit von anderen Standardprofilen, insbesondere IEC 61970-452 und IEC 61970-456, die die notwendigen Rahmenbedingungen für den Austausch festlegen. Dies zeigt die Relevanz der Norm im Kontext anderer Normen und deren Notwendigkeit für einen vollständigen Austausch der erforderlichen Daten für transiente Analysewerkzeuge. Die vorliegende zweite Auflage, die die erste Auflage von 2021 ersetzt, enthält bedeutende technische Änderungen, die auf die behobenen Probleme in IEC 61970-302:2018 zurückgehen. Dazu gehören die vollständige Abdeckung von IEEE 421.5-2016 bezüglich Erregersystemen und die Berücksichtigung relevanter Berichte über Turbinen, was zu einer Erweiterung der Modelle für Gas-, Dampf- sowie Wasserturbinen führte. Insgesamt unterstreicht die Norm SIST EN IEC 61970-457:2024 ihre Relevanz durch die Bereitstellung einer standardisierten Schnittstelle für dynamische Modellinformationen und fördert damit den Fortschritt im Bereich des Energiemanagements sowie die Effizienz und Sicherheit von Stromsystemen.

La norme SIST EN IEC 61970-457:2024 joue un rôle essentiel dans la spécification d'une interface standard pour l'échange d'informations sur les modèles dynamiques nécessaires à l'analyse de la stabilité à l'état稳(stabilité à petits signaux) et/ou à la stabilité transitoire d'un système électrique. Le champ d'application de cette norme se concentre exclusivement sur les informations de modèle dynamique devant être échangées dans le cadre d'une étude dynamique, englobant ainsi les types, descriptions et paramètres de chaque équipement de contrôle associé à un élément du système électrique. Une des forces majeures de cette norme réside dans sa dépendance par rapport à d'autres normes, comme celles spécifiées dans la norme IEC 61970-452, qui traite des modèles de transmission réseau statiques. Cela garantit que les échanges d’informations de modèle dynamique sont contextuellement ancrés dans le cadre d'une solution à l'état stable d'un modèle de réseau électrique complet. De plus, la façon dont les différents standards peuvent être combinés pour former divers types d'échanges de modèles de réseau électrique est placée sous une lumière claire grâce à la norme IEC 61970-456. La norme soutient l'échange de deux types principaux de modèles dynamiques : les modèles standards, qui consistent en une approche simplifiée comprenant des bibliothèques pré-définies reliant le comportement dynamique des éléments de système électrique, et les modèles personnalisés, qui permettent aux utilisateurs d'échanger les paramètres de dispositifs propriétaires. Ce dernier aspect offre une flexibilité et une adaptabilité aux besoins spécifiques des utilisateurs, renforçant ainsi la pertinence de cette norme dans un environnement où les exigences des systèmes énergétiques sont en constante évolution. Le fait que cette deuxième édition remplace la première édition de 2021 est illustratif des efforts continus d'amélioration et d'adaptation technique. Les changements techniques significatifs, notamment l'incorporation des normes relatives aux systèmes d’excitation et des modèles de turbines, ainsi que l'approche renforcée pour les modèles définis par l'utilisateur, témoignent d'une attention particulière portée aux évolutions technologiques et aux attentes croissantes des utilisateurs finaux. En somme, la norme SIST EN IEC 61970-457:2024 représente une avancée notable dans le domaine des interfaces de gestion de l'énergie, ses exigences précises et ses raccordements à d'autres normes offrant une base solide pour la mise en œuvre d'échanges efficaces dans les études dynamiques des systèmes électriques.
