IEC 62934:2021提供了可再生能源发电并网主题领域的术语和定义。并网的技术问题主要集中在具有可变源和/或基于转换器的技术的可再生能源发电引起的问题，例如风力发电和光伏发电。一些可再生能源发电，例如具有相对连续可用的一次能源和旋转发电机的水力发电和生物质发电，是常规发电源，因此不在本文档中涵盖。 本文件的意图是回答“这些词是什么意思”的问题，而不是“这些术语在什么条件下适用”的问题。

IEC 62934:2021 provides terms and definitions in the subject area of grid integration of renewable energy generation. The technical issues of grid integration mainly focus on the issues caused by renewable energy generation with variable sources and/or converter based technology, such as wind power and photovoltaic power generation. Some renewable energy generations such as hydro power and biomass power with a relatively continuously available primary energy source and a rotating generator are conventional sources of generation, and are therefore not covered in this document.
The intention of this document is to answer the question "what do the words mean" and not "under what conditions do the terms apply".
