IEC 62909-2:20 19规定了特定分布式能源（即电动汽车（EV）、电池和光伏（PV）系统）的GCPC接口要求。这些要求是对IEC 62909-1中给出的一般要求的补充。 本国际标准将与IEC 62909-1:20 17结合使用。 本文件中的特殊要求条款是对IEC 62909-1:20 17中相应条款的补充或修改。如果后续条款的文本表明“添加”或“替换”IEC 62909-1:20 17的相关要求、测试规范或解释，则这些变更是对IEC 62909-1:20 17的相关文本进行的。如果无需变更且该条款适用，则使用“应适用IEC 62909-1:20 17第XX条的规定”。IEC 62909-1:20 17中未包含的附加条款、表格、图表和注释从101开始编号。

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 62909-1:2017. 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.
