IEC TR 63401-1:2022（E）讨论了将基于逆变器的资源连接到低短路比交流网络的挑战、关键技术问题和新兴技术。存在稳态稳定性问题、瞬态稳定性问题和振荡稳定性问题，这是与基于逆变器的资源或传统发电机相比最明显的差异，因此给操作、控制、保护等带来了新的挑战。因此，需要技术解决方案。潜在的解决方案将包括新的技术、方法和实践，以提供更大的灵活性并提高电力系统的效率。预计本文件还可为相关问题的进一步标准化提供指导

IEC TR 63401-1:2022(E) discusses the challenges of connecting inverter-based resources to low short circuit ratio AC networks, key technical issues and emerging technologies. There are the steady-state stability issue, transient state stability issue, and oscillatory stability issue, which are the most distinct differences compared to inverter-based resources or traditional generators, and accordingly brings new challenges to operation, control, protection, etc. Therefore, technical solutions are needed. The potential solutions will include new technologies, methods and practices, in order to provide more flexibility and improve the efficiency of power systems. It is expected that this document can also provide guidance for further standardization on relevant issues
