Framework for energy market communications - Part 503: Market data exchanges guidelines for the IEC 62325-351 profile

This part of IEC 62325 is for European electricity markets.
This document specifies a standard for a communication platform which every Transmission
System Operator (TSO) in Europe can use to exchange reliably and securely documents for
the energy market. Consequently a European market participant (TSO, regional supervision
centre, distribution utility, power exchange, etc.) could benefit from a single, common,
harmonised and secure platform for message exchange with other participants; thus, reducing
the cost of building different information technology (IT) platforms to interface with all the
parties involved.
“MADES” (MArket Data Exchange Standard) is the acronym to designate this standard.
MADES is a specification for a decentralised common communication platform based on
international IT standards:
• From an application program perspective, MADES specifies the software interfaces to
exchange electronic documents with peer applications. Such interfaces mainly provide
means to send and receive documents using a so-called “MADES communication system”
(or "MADES system" or simply "system"). The sender can request about the status of the
delivery of a document and the recipient issues a message back, the acknowledgement,
when receiving the document. This makes a MADES system usable for exchanging
documents in business processes requiring a reliable delivery.
• MADES also specifies services hidden to the applications such as recipient localisation,
recipient connection status, message routing and security. Services include directory,
authentication, signing, encryption, message tracking, message logging and message
temporary storage.
The purpose of MADES is to create a secured message exchange standard based on
standard communication protocols and utilising IT best practices for exchanging data over any
TCP/IP communication network, in order to facilitate business-to-business (B2B) information
exchanges as described in IEC 62325-351 and the IEC 62325-451 series.
A MADES system acts as a post-office organisation: the transported object is a “message” in
which the document of the sender is securely packaged in an envelope containing metadata,
which is necessary information for transportation, tracking and delivery.

Kommunikation im Energiemarkt - Teil 503: Richtlinien zum Austausch von Marktdaten für das Profil der IEC 62325-351

Cadre pour les communications pour le marché de l'énergie - Partie 503: Lignes directrices concernant les échanges de données du marché pour le profil défini dans l’IEC 62325-351

IEC 62325-503:2018 spécifie une norme relative à une plate-forme de communication que chaque gestionnaire de réseau de transport (GRT) en Europe peut utiliser pour échanger en toute fiabilité et sécurité des documents destinés au marché de l’énergie. Par conséquent, un participant aux marchés européens (GRT, centre régional de surveillance, régie de distribution, bourse d’électricité, etc.) peut tirer profit d’une plate-forme commune unique harmonisée et sûre d’échange des messages avec les autres participants, réduisant ainsi le coût de mise en place de différentes plates-formes de technologies de l’information (TI) assurant l’interface avec toutes les parties concernées. Cette édition annule et remplace l'IEC TS 62325-503 parue en 2014.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) Utilisation de l’ISO/IEC 19464:2014, Advanced Message Queuing Protocol (AMQP) v1.0 specification (disponible en anglais seulement);
b) Répartition du nœud décrit dans l’IEC TS 62325-503:2014 dans un courtier qui met en œuvre la fonction de transmission de messages et un annuaire;
c) Renforcement de l’opérabilité et de la résilience du système de communication avec capacité pour un point d’extrémité d’envoyer et de recevoir des messages par l’intermédiaire de plusieurs courtiers;
d) Avantage issu de la normalisation, des performances et de l’évolutivité du protocole AMQP de transfert de messages.

Okvir za komunikacije na trgu z električno energijo - 503. del: Smernice za izmenjavo podatkov na trgu za profil IEC 62325-351

Ta del standarda IEC 62325 je namenjen za evropski trg z električno energijo. Ta dokument določa standard za komunikacijsko platformo, ki jo lahko vsak sistemski operater (TSO) v Evropi uporablja za zanesljivo in varno izmenjavo dokumentov na področju trgovanja z električno energijo. Posledično bi lahko udeleženec na evropskem trgu (sistemski operater, regionalni nadzorni center, distribucijsko podjetje, borza z električno energijo ipd.) imel koristi od ene, skupne, usklajene in varne platforme za izmenjavo sporočil z drugimi udeleženci, s čimer bi se zmanjšali stroški gradnje različnih platform informacijske tehnologije (IT) za povezovanje vmesnikov vseh vpletenih strank.
»MADES« (Market Data Exchange Standard – standard za izmenjavo podatkov na trgu) je kratica, ki označuje ta standard. MADES je specifikacija za decentralizirano skupno komunikacijsko platformo, ki temelji na mednarodnih standardih informacijske tehnologije.
• Z vidika programske aplikacije MADES določa vmesnike programske opreme za izmenjavo elektronskih dokumentov z enakovrednimi aplikacijami. Taki vmesniki ponujajo način pošiljanja in prejemanja dokumentov z uporabo tako imenovanega »komunikacijskega sistema MADES« (ali »sistema MADES« oziroma preprosto »sistema«). Pošiljatelj lahko zahteva stanje dostave dokumenta in prejemnik ob prejemu dokumenta pošlje povratno sporočilo s potrditvijo. Tako je sistem MADES uporaben za izmenjavo dokumentov v poslovnih procesih, ki zahtevajo zanesljivo dostavo.
• MADES prav tako določa storitve, skrite aplikacijam, kot so lokalizacija prejemnika, stanje povezave prejemnika, usmerjanje sporočil in varnost. Storitve vključujejo imenik, preverjanje pristnosti, vpisovanje, šifriranje, sledenje sporočilom, beleženje sporočil v dnevnik in začasno hrambo sporočil.
Namen sistema MADES je ustvariti standard varne izmenjave sporočil, ki temelji na standardnih komunikacijskih protokolih in uporablja najboljše prakse informacijske tehnologije za izmenjavo podatkov prek komunikacijskega omrežja TCP/IP, da se omogočijo izmenjave informacij med podjetji (B2B), kot je opisano v standardu IEC 62325-351 in skupini standardov IEC 62325-451.
Sistem MADES deluje kot poštna organizacija: preneseni predmet je »sporočilo«, v katerem je dokument pošiljatelja varno zapakiran v ovojnici z metapodatki oziroma potrebnimi informacijami za prenos, sledenje in dostavo.
