近日，全球首个光伏直流领域国际标准《分布式光伏接入低压直流系统及用例》(IEC TR 63534 ED1:2025)正式发布，该标准由上海交通大学和华能江苏公司牵头，与来自德国、美国等14个国家的专家组成工作组，历经4年协同合作，共同完成编制。

近年来，我国分布式光伏产业呈现蓬勃发展态势，随着分布式光伏发电进入平价市场化发展阶段，亟需科学、统一的国际标准。该国际标准聚焦分布式光伏接入低压直流系统的典型场景与关键技术，系统梳理了全球范围内相关典型工程案例，总结了光伏直流接口装备的技术演化规则，明确了低压直流系统在系统控制、故障响应及稳定运行等方面的技术指标要求，为分布式光伏开发与新型配电系统建设奠定了基础，为全球分布式光伏产业的发展提供了指南。
