报告简介

全球能源转型正为电力系统带来前所未有的运行挑战，其典型特征在于波动性可再生能源的大规模并网，以及吉瓦级间歇性负荷的涌现。本报告将结合巴西的最新实践，深入探讨系统运行模式的演变，重点分析电池储能系统（BESS）在平抑“鸭型曲线”中的关键作用，以及输配电（T&D）协调管理的迫切需求。报告核心聚焦于高压直流（HVDC）技术的发展趋势，详述了巴西在未来互联工程中强制采用VSC-MMC技术的决策背景，以及大功率双向换流站的具体技术规范。此外还将剖析氢能产业与人工智能数据中心带来的双重压力，这两者因其间歇性和巨大的功率需求，进一步增加了电网运行的复杂度。最后，强调通过CIGRE等平台加强行业经验交流与信息共享的重要性，并指导中国先进输电技术在海外应用的方向。

The global energy transition is introducing unprecedented operational complexities to power systems, characterized by the large-scale integration of variable renewable energy and the emergence of gigawatt-scale, intermittent loads. Drawing on recent Brazilian experience, this presentation examines the evolving landscape of system operation, highlighting the critical role of Battery Energy Storage Systems (BESS) in mitigating the "duck curve" and the necessity for coordinated Transmission and Distribution (T&D) management. A significant focus is placed on the future of HVDC technology, detailing Brazil’s shift toward mandatory VSC-MMC technology for upcoming interconnections and the technical specifications for high-power, bi-directional converters. Furthermore, the report addresses the dual challenges posed by the hydrogen economy and AI-driven Data Centers, which introduce new layers of uncertainty regarding grid stability. The discussion concludes by emphasizing the industry's need for robust information sharing through platforms like CIGRE and advocating for greater clarity in the international application of advanced HVDC technologies.
