IEC TR 61850-90-7:20 23作为IEC TR 61850-90-7:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC TR 61850-90-7:20 23是一份技术报告，描述了基于功率转换器的分布式能源(DER)系统的功能，重点关注直流到交流和交流到交流转换，包括光伏系统(PV)、电池存储系统、电动汽车(EV)充电系统以及任何其他具有可控功率转换器的DER系统。本文件中定义的功能用于帮助定义IEC 61850-7-420中描述的信息模型，可用于这些基于功率转换器的DER系统与公用事业公司、能源服务提供商（ESP）或其他负责管理这些功率转换器的伏特、无功和瓦特能力的实体之间的信息交换。基于系统。这些基于功率转换器的DER系统的范围可以从住宅客户站点的非常小的并网系统，到校园或社区中配置为微电网的中型系统，到公用事业运营的发电厂中的非常大的系统，以及许多其他配置和所有权模式。它们可以或可以不在功率转换器后面组合不同类型的DER系统，例如基于功率转换器的DER系统和在DC电平连接的电池。这第二版取消并取代了2013年出版的第一版。本版本主要是编辑修订，以便与IEC 61850-7-420:2021第2版的发布保持一致。与上一版相比，此版本包含以下重大变更:a)第3条已更新。b)删除了第8条（基于功率转换器的功能的IEC 61850信息模型）。该条款定义了具有过渡命名空间“(Tr)IEC 61850-90-7:20 12”的数据模型。数据模型现在在IEC 61850-7-420中定义。

IEC TR 61850-90-7:2023 is available as IEC TR 61850-90-7:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document were used to help define the information models described in IEC 61850-7-420 and which can be used in the exchange of information between these power converter-based DER systems and the utilities, energy service providers (ESPs), or other entities which are tasked with managing the volt, var, and watt capabilities of these power converter-based systems. These power converter-based DER systems can range from very small grid-connected systems at residential customer sites, to medium-sized systems configured as microgrids on campuses or communities, to very large systems in utility-operated power plants, and to many other configurations and ownership models. They may or may not combine different types of DER systems behind the power converter, such as a power converter-based DER system and a battery that are connected at the DC level. This second edition cancels and replaces the first edition published in 2013. This edition is primarily an editorial revision in order to be consistent with the publication of Edition 2 of IEC 61850-7-420:2021. This edition includes the following significant changes with respect to the previous edition:
a) Clause 3 has been updated.
b) Clause 8 (IEC 61850 information models for power converter-based functions) has been deleted. This clause defined data models with the transitional namespace “(Tr) IEC 61850-90-7:2012”. The data models are now defined in IEC 61850-7-420.
