IEC 61968-5:2020

Application integration at electric utilities - System interfaces for distribution management - Part 5: Distributed energy optimization

Edition date: 2020-08-18
In Force
Available languages: English, French
Summary: IEC 61968-5:2020 is the description of a set of functions that are needed for enterprise integration of DERMS functions. These exchanges are most likely between a DERMS and a DMS. However, since this is an enterprise integration standard which may leverage IEC 61968-100:2013 for application integration (using web services or JMS) or other loosely-coupled implementations, there are no technical limitations for systems with which a DERMS might exchange information. Also, it should be noted that a DERMS might communicate with individual DER using a variety of standards and protocols such as IEC 61850, IEEE 2030.5, Distribution Network Protocol (DNP), Sunspec Modbus, or perhaps Open Field Message Bus (OpenFMB). One role of the DERMS is to manage this disparity and complexity of communications on the behalf of the system operator. However, the communication to individual DER is out of scope of this standard. Readers should look to those standards to understand communication to individual DER’s smart inverter.
The scope will be limited to the following use case categories:
• DER group creation – a mechanism to manage DER in aggregate
• DER group maintenance – a mechanism to add, remove, or modify the members and/or aggregated capabilities of a given group of DER
• DER group deletion – removing an entire group
• DER group status monitoring – a mechanism for quantifying or ascertaining the current capabilities and/or status of a group of DER
• DER group forecast – a mechanism for predicting the capabilities and/or status of a group of DER for a given time period in the future
• DER group dispatch – a mechanism for requesting that specified capabilities of a group of DER be dispatched to the grid
• DER group voltage ramp rate control – a mechanism for requesting that a DER group following a ramp rate curve
• DER group connect/disconnect – a mechanism to request that DER either isolate themselves, or reconnect to the grid as needed.

IEC 61968-5:2020 est la description d'un ensemble de fonctions indispensables à l'intégration par les entreprises des fonctions DERMS. Ces échanges sont les plus susceptibles d'avoir lieu entre un DERMS et un DMS. Toutefois, étant donné qu'une norme d'intégration par les entreprises peut s'appuyer sur l'IEC 61968 100:2013 pour l'intégration d'applications (par le biais de services web ou de la technologie JMS) ou d'autres implémentations faiblement couplées, les systèmes avec lesquels un DERMS peut échanger des informations ne font l'objet d'aucune limite technique. De même, il convient de noter qu'un DERMS peut communiquer avec une DER individuelle en utilisant une variété de normes et de protocoles comme l'IEC 61850, l'IEEE 2030.5, le protocole DNP (Distribution Network Protocol – Protocole de réseau de distribution), Sunspec Modbus, voire Open Field Message Bus (OpenFMB). Un rôle du DERMS consiste à gérer cette disparité et cette complexité des communications au nom de l'opérateur système. Toutefois, la communication avec la DER individuelle est hors du domaine d'application de la présente norme. Il convient que le lecteur consulte ces normes pour comprendre la communication avec l'onduleur intelligent d'une DER individuelle.
Le domaine d'application est limité aux catégories de cas d'utilisation suivantes:
• création de groupe de DER – mécanisme de gestion de DER en agrégat;
• maintenance de groupe de DER – mécanisme d'ajout, de retrait ou de modification des membres et/ou capacités agrégées d'un groupe de DER donné;
• suppression de groupe de DER – suppression d'un groupe entier;
• surveillance du statut d'un groupe de DER – mécanisme de quantification ou de vérification des capacités réelles et/ou du statut d'un groupe de DER;
• prévision de groupe de DER – mécanisme de prévision des capacités et/ou du statut d'un groupe de DER pour une période donnée ultérieure;
• répartition de groupe de DER – mécanisme de demande de répartition des capacités spécifiées d'un groupe de DER sur le réseau;
• contrôle du taux de rampe de tension du groupe de DER – mécanisme permettant de demander qu'un groupe de DER respecte la courbe de taux de rampe;
• branchement/débranchement du groupe de DER – mécanisme permettant de demander que les DER s'isolent elles-mêmes ou se reconnectent au réseau, en fonction des besoins.

  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.
