Energy management system application program interface (EMS-API) - Part 457: Dynamics profile
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 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: a) La majorité des problèmes identifiés dans l’IEC 61970-302:2018 et réglés dans l’IEC 619
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
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.

Cette norme définit une interface standard pour l'échange d'informations sur les modèles dynamiques nécessaires à l'analyse de la stabilité dans les systèmes électriques, que ce soit pour une stabilité à l'état stationnaire (stabilité à petit signal) ou pour la stabilité transitoire. L'une des forces majeures de cette norme réside dans son interconnexion avec le CIM (Common Information Model), notamment à travers la norme IEC 61970-302. Le fait que la norme s'appuie sur des modèles dynamiques déjà préexistants permet une intégration harmonieuse et une utilisation efficace des données. En limitant son champ d'application aux informations nécessaires pour une étude dynamique, la norme assure également une clarté et une pertinence dans l'échange des données. Les détails concernant le type, la description et les paramètres de chaque équipement de contrôle associés à un réseau d'énergie sont cruciaux pour garantir des analyses précises. De plus, la norme prend en charge différents types de modèles dynamiques, notamment les modèles standards et les modèles définis par l'utilisateur. Cette flexibilité, avec la possibilité d'utiliser des modèles propriétaires, est un atout considérable, car elle répond à la diversité des besoins des utilisateurs tout en maintenant une structure d'échange cohérente. En raison de l'importante révision technique apportée dans cette seconde édition, la norme intègre des mises à jour sur divers systèmes et modèles qui contribuent à son actualité et à sa pertinence dans le domaine de la gestion de l'énergie. Les ajouts significatifs, tels que les modèles d'inverseurs et les turbines, garantissent que cette norme reste en phase avec les évolutions technologiques récentes. En somme, la norme SIST EN IEC 61970-457:2024 présente une approche standardisée et robuste pour l'échange d'informations dynamiques, renforçant ainsi la capacité d'analyse des systèmes électriques tout en soutenant les outils d'analyse transitoire. Cette norme est incontournable pour les professionnels du secteur, car elle assure un cadre fiable pour la gestion des dynamiques au sein des systèmes d'énergie.
SIST EN IEC 61970-457:2024 표준 문서는 에너지 관리 시스템 애플리케이션 프로그래밍 인터페이스(EMS-API)의 다이내믹스 프로파일에 대한 정의를 제공합니다. 이 표준은 전력 시스템의 정상 상태 안정성 및 기타 변동 안정성 분석을 지원하기 위해 필요한 동적 모델 정보를 교환하기 위한 표준 인터페이스를 명시하고 있습니다. 특히, IEC 61970-302에서 파생된 CIM을 기반으로 한 스키마는 동적 연구의 일환으로 해당하는 전력 시스템 장비의 제어 장비 유형, 설명 및 파라미터의 교환을 포함하고 있습니다. 이 문서의 주요 강점은 전력 시스템 네트워크 모델에서 정상 상태 솔루션과 함께 교환되어야 하는 동적 모델 정보를 명확히 정리하고 있다는 점입니다. 또한, IEC 61970-452 및 IEC 61970-456 프로파일과의 연계를 통해 변동 분석 도구의 데이터 요구 사항을 지원합니다. 이러한 통합적인 접근은 사용자가 표준 모델과 사용자 정의 모델을 손쉽게 교환할 수 있도록 하여 전력 시스템의 동적 행동을 더 잘 이해할 수 있도록 돕습니다. 이 표준은 특히 다음과 같은 유형의 동적 모델을 교환할 수 있게 합니다. 첫째, 표준 모델은 사전 정의된 클래스 라이브러리에 포함된 단순화된 접근 방식으로, 전력 시스템 요소의 동적 행동을 나타냅니다. 둘째, 비공식 사용자 정의 모델은 사용자가 특정 공급업체의 장비를 나타내는 모델의 파라미터를 교환할 수 있도록 하며, 여기서는 모델에 대한 구체적인 설명은 제공되지 않습니다. SIST EN IEC 61970-457:2024의 두 번째 판은 2021년에 발표된 첫 번째 판을 대체하며, 이전 판에서 식별된 다양한 문제를 해결한 기술적 개정판입니다. IEEE 421.5-2016의 흥미로운 시스템은 완전히 포괄되며, 2013년의 IEEE 터빈 보고서를 반영하여 여러 가스, 증기 및 수력 터빈/조절기가 추가되었습니다. IEC 61400-27-1:2020을 포함하여 풍력 터빈 관련 정보도 완벽하게 통합되었습니다. 이러한 모든 요소는 전력 시스템의 동적 모델 교환을 지원하는 데 매우 중요한 역할을 합니다. SIST EN IEC 61970-457:2024 표준 문서는 전력 시스템 특성의 변동성을 분석하고 제어하기 위한 필수적인 기준을 제공하는 동시에, 광범위한 애플리케이션에서의 활용성을 보장합니다. 이를 통해 에너지 관리 시스템의 효율성을 높이는 데 기여하는 전략적 도구로 자리 잡고 있습니다.
Die Norm EN IEC 61970-457:2024, die sich mit der Energiemanagementsystem-Anwendungsprogrammierschnittstelle (EMS-API) befasst, stellt eine entscheidende Erneuerung im Bereich des Austauschs dynamischer Modellsysteminformationen dar. Der Hauptfokus dieser Norm liegt auf der Unterstützung der Analyse der stationären Stabilität (klein-signal Stabilität) und der transitorischen Stabilität innerhalb von Stromsystemen. Durch die Definition einer standardisierten Schnittstelle, die auf den CIM (Common Information Model) basiert, leistet die Norm einen bedeutenden Beitrag zur Effizienzsteigerung und Kompatibilität bestehender Tools zur dynamischen Analyse. Eine der herausragenden Stärken dieser Norm ist die klare Definition der auszutauschenden dynamischen Modellinformationen. Dies umfasst spezifische Typen, Beschreibungen und Parameter von Steuergeräte-Ausrüstungen, die in die stationären Lösungen von Stromnetzmodellen integriert sind. Der umfassende Ansatz, der sowohl standardisierte Modelle als auch proprietäre benutzerdefinierte Modelle unterstützt, ermöglicht eine flexible Anwendung in einer Vielzahl von Szenarien. Die Integration dieser beiden Modelltypen fördert den Austausch von Informationen, auch wenn spezifische Details für proprietäre Modelle nicht in der Norm abgedeckt sind, da der Empfänger den Anbieter kontaktieren muss, um Verhaltensdetails zu erhalten. Die Norm ist klar auf die neuesten technischen Entwicklungen ausgerichtet, indem sie relevante Aktualisierungen aus früheren Ausgaben integriert, darunter die vollständige Abdeckung der IEEE 421.5-2016-Normen zu Erregersystemen und die Berücksichtigung von wesentlichen Entwicklungen bei Turbinenmodellen. Dies zeigt die Relevanz und Anwendbarkeit der Norm im aktuellen technischen Umfeld sowie die Bemühungen, den Austausch dynamischer Modelle kontinuierlich zu verbessern. Zusammenfassend bietet die EN IEC 61970-457:2024 eine robuste, standardisierte Grundlage für den Austausch von dynamischen Modellen in Energiemanagementsystemen, die nicht nur die Interoperabilität zwischen verschiedenen Tools und Systemen gewährleistet, sondern auch die Qualität der Analyse in Bezug auf die Stabilität von Stromsystemen erheblich verbessert. Die Norm fördert somit eine effektivere Zusammenarbeit und ein besseres Verständnis der dynamischen Aspekte von Energieanwendungen.
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、動的モデル情報を交換するための標準インターフェースを規定する重要な文書です。この文書の範囲は、電力システムやその一部の定常状態安定性（小信号安定性）および過渡安定性の分析を支援するために必要な動的モデル情報の交換に特化しています。具体的には、電力システム機器に関連する各制御装置のタイプ、説明、およびパラメータを含みます。 この標準は、IEC 61970-302に基づくCIMから直接導出されたスキーマを使用しており、電力システムの全体のネットワークモデルの定常状態解に含まれる装置に関連する制御機器からの動的モデル情報の交換を対象としています。この文書は、IEC 61970-452およびIEC 61970-456の標準プロファイルに依存しており、動的分析ツールのデータ要件をサポートするための情報交換を促進します。また、IEC 61970-456は、さまざまな電力システムネットワークモデル交換を形成するために異なるプロファイル標準がどのように組み合わさるかについて詳細に説明しています。 EN IEC 61970-457の強みは、標準モデルとユーザー定義モデルの両方を支援する点にあります。標準モデルでは、動的挙動を代表する要素を表すクラスの定義済みライブラリから簡素化されたアプローチを用いており、交換時にはモデル名とその挙動を説明するために必要な属性のみが示されます。一方、ユーザー定義モデルは、ベンダーまたはユーザーの特許デバイスを表すモデルのパラメータを交換可能にし、その詳細については送信者とコンタクトを取る必要があります。 この標準は、2021年に発表された初版を廃止し、技術的な改訂を含む第2版として発表されました。特に、IEC 61970-302:2022で修正された問題点が多く反映されており、IEEE 421.5-2016や風力タービン、ハイブリッドSTATCOMモデル、貯蔵モデルなどの新しい技術も盛り込まれています。このように、EN IEC 61970-457:2024は、電力システムの動的モデル情報の標準化と相互運用性の向上に寄与しており、エネルギー管理システムの発展において重要な役割を果たすことが期待されます。
