IEC TR 61000-2-15:20 23是一份技术报告，特别解决了以下主要现象，这些现象影响了电力电子转换器渗透率高的现代配电系统中的电能质量。由于该主题的某些方面在过去已经被解决，考虑到LV和MV网络的演变，本文档侧重于以下方面: 网络中的共振、建模和现场验证； 超谐波和测量问题； 电力电子转换器数量增加的影响； 待连接设备的稳定性和不稳定性问题 本文件的目标现象和条件如下: 频率:≤2kHz，2kHz至9kHz，≥9kHz； 电压等级:LV、MV； 谐波源:所有类型的转换器（电动汽车电池充电器、电器等。…). 这些频率范围中的一些已经在一些国家（日本、德国、瑞士等）标准化。），但是由此产生的现象将有利于更详细地描述，重点是转换器和电网之间的相互作用。大量转换器的存在也岌岌可危。当整个系统不再稳定时，也会出现一些复杂的现象。笔记？尽管预计本文件中的模型和推导计算可应用于美洲电气系统，但其正式验证研究仍有待进行。

IEC TR 61000-2-15: 2023 which is a Technical Report, addresses in particular the following main phenomena, which affect the power quality in modern distribution systems with high penetration of power electronics converters. As some aspects of the subject have already been addressed in the past, considering the evolution of the LV and MV networks, this document focuses on the following aspects:

• resonances in the network, modelling and on-site validation;
• supraharmonics and measurements issues;
• impact of increased number of power electronic converters;
• stability and instability issues for the equipment to be connected

The target phenomena and conditions of this document are the following:

• frequency: ≤ 2 kHz, 2 kHz to 9 kHz, ≥ 9 kHz;
• voltage levels: LV, MV;
• harmonic sources: all types of converters (EV battery chargers, appliances, etc.…).

Some of these frequency ranges have already been standardized in some countries (Japan, Germany, Switzerland, etc.), but the resulting phenomena developed will benefit being described in more details, with a focus on the interaction between the converters and the electrical networks. The case of the presence of a large number of converters is also at stake. Some complex phenomena can also arise when the full system is not stable anymore. NOTE？Whereas it is expected that the models and derived calculations form this document can be applied to the Americas electrical systems its formal validation studies are still pending.
