本指南的范围包括通过电力电子接口（通常称为变流器、逆变器或双向逆变器）连接到电力系统（EPS）的ES DER，其能够双向有功和无功潮流，并能够向EPS输出有功功率。本文件还为可能影响电力系统的非出口设备提供了指导，例如，根据系统频率按比例调节负载，例如一些不间断电源（UPS）系统和电动汽车（EV）充电器。

This guide provides information on, and examples of, how to apply IEEE Std 1547-2018 for the interconnection of energy storage distributed energy resources (ES DER). The guide's scope includes ES DER that are interfaced to an electric power system (EPS) via a power electronic interface (commonly referred to as a converter, inverter, or bidirectional inverter), capable of bidirectional active and reactive power flow, and capable of exporting active power to the EPS. The document also provides guidance for non-exporting ES DER that could have power system impacts, e.g., modulating load proportionally to system frequency, such as some uninterruptible power supply (UPS) systems and electric vehicle (EV) chargers.
