电动汽车提供电网支持功能的系统架构和用例

[中文适用范围]： IEC SRD 63460:2025 本文件的范围是评估当电动汽车（EVs）通过充电站连接到电力系统时，它们可能（或必须）作为分布式能源资源（DER）的行为。虽然显然电动汽车接入电网的主要目的是为其电池充电，但在连接状态下，电动汽车能够提供电网支持功能，在某些情况下，还可能被要求或激励执行这些功能。本文件提供了用例作为示例，说明基于IEC 61850-7-420、IEEE 1547:2018和EN 50549中定义的电网支持功能，电动汽车如何提供此类DER功能。 [外文原描述]： IEC SRD 63460:2025 The scope of this document is the assessment of how Electric Vehicles (EVs) may (or must) act as Distributed Energy Resources (DER) when they are interconnected to the electric power system through a charging station. Although clearly the main purpose for EV interconnection to the grid is to charge their batteries, EVs are capable of providing grid support functions while interconnected, and in some situations, may be mandated or incentivized to do so. This document provides Use Cases as examples of how EVs might provide such DER functionality, based on the grid support functions defined in IEC 61850-7-420, IEEE 1547:2018, and EN 50549.
