在回顾当今电力电子的趋势研究时，KNOWLES曾讨论了可再生能源市场的增长以及由此带来的对风能等可再生能源技术投资的增加。这一趋势直接引发了全球对风能需求的激增。为了应对这一挑战并抓住机遇，我们不仅在陆地和海洋部署了更多的风力涡轮机，而且每台涡轮机的发电效率和容量也实现了显著的提升。这一变革深刻地影响了对相关电力电子设备的需求和规格要求。

在本篇文章中，Knowles将深入探讨一系列风力发电领域关键的现有发展趋势，这些趋势不仅推动了发电能力的全面提升，也引领了电力电子设备技术的创新和转型。Knowles将重点关注这些前沿动态，揭示它们如何共同塑造未来风力发电系统的新面貌，以及为电力电子行业带来的新机遇和挑战。

1、平准化能源成本（LCOE）的大幅降低

为了衡量发电资产在整个使用周期内的平均总成本与总能量产出之间的关系，我们引入了一个关键指标——平准化能源成本（LCOE）。这一指标为不同能源形式的成本效益分析提供了有效的衡量工具。通常情况下，能源供应商更愿意为那些可靠性更高、使用寿命更长的系统支付额外成本，以此确保长期的供应稳定性和经济效益。

在过去十年中，得益于科技进步、运营效率的提升以及风力发电技术的突飞猛进，风力发电的LCOE已经大幅降低。这些进展不仅增强了风力发电的经济竞争力，也促进了其在全球能源结构中的广泛应用和普及。

2、风力涡轮机功率水平显著提高

在过去二十年中，提升风力涡轮机单机输出功率的需求急剧上升。得益于转换器技术的显著进步，风力涡轮机的发电效率实现了质的飞跃，如图2所示。2023年，陆上风力涡轮机配备的转换器已能产生高达8.5兆瓦的电力，而海上风力涡轮机的发电能力更是达到了令人瞩目的18兆瓦。
