标准摘要
[中文适用范围]： 本部分IEC 62898作为技术规范，旨在为微电网项目规划和规范提供指导。本文档考虑的微电网是带有负载和分布式能源资源（DER）的交流（AC）电力系统，电压等级为低压或中压。本文档不涵盖直流（DC）微电网。微电网分为孤立微电网和非孤立微电网。孤立微电网与更广泛的电力系统没有电气连接。非孤立微电网可以作为电力系统的可控单元，并可以在以下两种模式下运行：- 并网模式；- 孤岛模式。本文档将涵盖以下领域：- 微电网应用、资源分析、发电预测和负荷预测；- DER规划和微电网电力系统规划；- 微电网中DER的高层次技术要求，微电网与配电系统的连接，以及控制、保护和通信系统的技术要求；- 微电网项目的评估。 [外文原描述]： IEC TS 62898-1:2017+AMD1:2023 provides guidelines for microgrid projects planning and specification. Microgrids considered in this document are alternating current (AC) electrical systems with loads and distributed energy resources (DER) at low or medium voltage level. This document does not cover direct current (DC) microgrids. Microgrids are classified into isolated microgrids and non-isolated microgrids. Isolated microgrids have no electrical connection to a wider electric power system. Non-isolated microgrids can act as controllable units to the electric power system and can operate in the following two modes: - grid-connected mode; - island mode. This document will cover the following areas: - microgrid application, resource analysis, generation forecast, and load forecast; - DER planning and microgrid power system planning; - high level technical requirements for DER in microgrids, for microgrid connection to the distribution system, and for control, protection and communication systems; - evaluation of microgrid projects.
