本指南提供了技术背景、基本原理和指南，以支持经大幅修订的IEEE 1547《分布式能源（DER）与电力系统（EPS）及相关接口互连和互操作性标准》的应用。该文件将描述如何仔细选择1547中规定的要求和默认设置，以平衡分配和批量系统需求，从而提高DER的渗透率。它进一步扩展了IEEE 1547，解决了基本标准未完全解决的某些DER集成问题，例如:。 g、 EPS区域的重合闸协调和过电压限制。该指南将阐述（1）新引入的性能类别的概念及其由管理互连要求的机构（AGIR）分配给特定DER的任务；（2） 对电压和无功功率控制、频率控制、异常情况响应（包括穿越）的新要求；（3） 新引入的控制设置以及电压和频率跳闸设置的可调节范围提供了灵活性，以充分利用经修订的IEEE 1547的潜力，并考虑特定的系统特性； （4） 互操作性和通信接口要求；以及（5）本标准之前版本中未包含的测试和验证实践，包括公用工程规模的设计和竣工安装评估。文件中提供了技术说明和示意图、应用指南和互连示例，以增强IEEE 1547的使用。

This guide provides the technical background, rationale and guidance to support the application of the substantially revised IEEE 1547, Standard for Interconnection and interoperability of Distributed Energy Resources (DER) with Electric Power Systems (EPS) and Associated Interfaces. The document will describe how the requirements and default settings specified in 1547 have been carefully chosen to balance distribution and bulk system needs for increasing penetration of DER. It further expands IEEE 1547 by addressing certain DER integration issues that are not fully addressed by the base standard, e.g. reclosing coordination and limitation of over-voltage in the Area EPS. The guide will address (1) the concept of the newly-introduced performance categories and their assignment to specific DER by an Authority Governing Interconnection Requirements (AGIR); (2) the new requirements for voltage and reactive power control, frequency control, response to abnormal conditions including ride-through; (3) the flexibility provided by the newly-introduced ranges of adjustability for control settings as well as for voltage and frequency trip settings to fully exploit the revised IEEE 1547's potential and to account for specific system characteristics; (4) the interoperability and communication interface requirements; and (5) the test and verification practices, including design and as-built installation evaluations for utility-scale DER, that have not been included in the previous version of the standard. Presented in the document are technical descriptions and schematics, applications guidance and interconnection examples to enhance the use of IEEE 1547.
