(Main)Bi-directional grid-connected power converters - Part 2: Interface of GCPC and distributed energy resources
Bi-directional grid-connected power converters - Part 2: Interface of GCPC and distributed energy resources
IEC 62909-2:2019 specifies GCPC interface requirements for particular distributed energy resources, namely electric vehicle (EV), battery, and photovoltaic (PV) systems. These requirements are in addition to the general requirements given in IEC 62909-1. This International Standard is to be used in conjunction with IEC 62909-1:2017. The clauses of particular requirements in this document supplement or modify the corresponding clauses in IEC 62909-1:2017. Where the text of subsequent clauses indicates an "addition" to or a "replacement" of the relevant requirement, test specification or explanation of IEC 62909-1:2017, these changes are made to the relevant text of IEC 629091:2017. Where no change is necessary and the clause is applicable, the words "The provisions of IEC 62909-1:2017, Clause XX shall apply" are used. Additional clauses, tables, figures and notes which are not included in IEC 62909-1:2017, are numbered starting from 101.
Bidirektionale netzgekoppelte Leistungsumrichter - Teil 2: Schnittstelle des GCPC und dezentrale Energiequellen
Convertisseurs de puissance connectés aux réseaux bidirectionnels - Partie 2: Interface du GCPC avec les ressources énergétiques réparties
l'IEC 62909-2:2019 définit les exigences d'interface du GCPC pour des ressources énergétiques réparties particulières, notamment les véhicules électriques (VE), les batteries et les systèmes photovoltaïques (PV). Ces exigences viennent compléter les exigences générales fournies dans l'IEC 62909-1. La présente Norme internationale doit être utilisée conjointement avec l'IEC 62909-1:2017. Les articles relatifs aux exigences particulières définies dans le présent document complètent ou modifient les articles correspondants de l'IEC 62909-1:2017. Lorsque le texte des articles suivants spécifie une "addition" ou un "remplacement" concernant une exigence, une spécification d'essai ou une explication fournie dans l'IEC 62909-1:2017, ces modifications se rapportent au texte correspondant de l'IEC 629091:2017. Lorsqu'aucune modification n'est nécessaire et que l'article est applicable, la phrase "Les dispositions de l'IEC 62909-1:2017, Article XX doivent s'appliquer" est employée. Les paragraphes, tableaux, figures et notes qui sont ajoutés à ceux de l'IEC 62909-1:2017 sont numérotés à partir de 101.
Dvosmerni omrežni elektroenergetski pretvorniki - 2. del: Vmesnik za GCPC in porazdeljene energijske vire (IEC 62909-2:2019)
Ta dokument določa zahteve za vmesnike GCPC za posamezne porazdeljene energijske vire, in sicer sisteme električnih vozil (EV), akumulatorske sisteme in fotonapetostne sisteme (PV). Te zahteve so dodatek k splošnim zahtevam iz standarda IEC 62909-1.
