" 在“近零能耗建筑”实践过程中，光伏发电无疑成为建筑电力供应的重要手段。传统的光伏发电均采用交流方案，然而随着大量的分布式光伏并网，低压电网的电能质量问题（谐波、不平衡）逐渐显现，导致电网公司对光伏并网做出了严格限制。光储直柔直流系统采用“自发自用，集中并网”的设计运行方式，不仅实现了分布式光伏的有效利用，还极大程度上解决了低压电网的电能质量问题，为规模化推进分布式光伏的发展提供了良好的技术支撑。与交流系统最大的区别在于分布式电源及负荷均通过直流接入，由于处于研究推广阶段，系统中的设备、控制、保护等均未形成系统性的技术方案和标准。针对上述现状，本课题在现有技术的基础上，从实际应用的角度，对建筑光储直柔系统主要技术进行梳理，并就其中部分关键技术展开实用化研究，形成不同场景下的光储直柔系统方案。 本课题的主要研究内容包括以下几个方面： （1）建筑光储直柔系统的源荷特性及优化控制策略 分析了建筑光储直柔系统内关键设备的现状和特...
