分布式能源配电网承载能力评估导则

[中文适用范围]： 本文档规定了评估分布式能源（DER）在配电网中最大输出容量的方法。它提供了评估承载容量时应考虑的技术约束、进行承载容量评估所需收集的信息以及评估方法的指导。 本文档适用于标称频率为50Hz或60Hz的交流配电网。 本文档未规定因配电网增加DER而可能影响的系统参数的允许值，如最大或最小电压、最大电流等。这些值应由用户根据国际或国家标准、地方法规等确定，并作为输入用于本文档描述的评估方法。 本文档主要由配电系统运营商（DSO）和其他具备相应资质和能力的组织使用。评估结果可作为DER投资者、DSO、能源行业监管机构和其他利益相关方的决策依据。 [外文原描述]： IEC TS 63276:2024 specifies methods for the evaluation of the maximum export capacity of distributed energy resources (DER) that distribution networks can accommodate. It provides guidance on the technical constraints that should be considered in evaluating hosting capacity, information required to be collected to undertake a hosting capacity evaluation, and evaluation methods. This document is applicable to AC distribution networks operating at a nominal frequency of 50 Hz or 60 Hz. This document does not specify allowable values of system parameters that can be impacted by the addition of DER on a distribution network, such as maximum or minimum voltage, maximum current, etc. These values are to be determined by the user, from international or national standards, local regulations or the like, and used as an input to the evaluation methods described in this document. This document is mainly used by distribution system operators (DSO) and other organizations with corresponding qualifications and capabilities. The evaluation results can serve the DER investors, DSO, energy sector regulators and other stakeholders as a decision-making basis.
