随着分布式能源发电及与其匹配的储能装置的广泛应用，电动汽车等新型负荷的接 入，电力市场化改革的推进，供电形式和能量流动方向的多样化发展，传统电力网络和 设备已很难满足电能控制的多样性和复杂性的要求。为了解决这一问题，能源互联网的 概念应运而生。能源路由器作为能源互联网的关键设备，具有重要的研究价值。本文对 多种类能源接入、能源多向流动的情况下，多端口能源路由器如何实现协调控制、系统 稳定运行进行了深入研究。本文针对多种类能源接入和功率分配的需求，对多端口能源 路由器的拓扑结构进行了选择，结合系统内能量传输特性，对光伏、蓄电池、电网接口 变换器的电路参数进行了设计。

       围绕直流母线稳压、最大功率跟踪、多目标交流并网等控制目标，对各功能单元接 入能源的特性及各对应变换器的控制方法进行了深入研究。通过对光伏电池的研究，设 计了光伏发电单元实现基于光伏特性的最大功率点跟踪、母线电压控制的控制方法；通 过对蓄电池模型和常用充放电方式的研究，设计了实现储能单元充放电控制及直流母线 稳压的多目标控制方法；通过对交直流变换单元工作方式的分析，设计了实现双向 DC/AC 变换器的直流稳压与功率可控的多目标控制方法。仿真结果表明，本文所选择 的各变换器控制方法能有效地完成预设的控制目标，稳态、动态性能良好。

       针对传统协调控制方法的不足，提出了一种主从控制和分层控制结合的协调控制方 法：将系统划分为底层控制层和中央管理层，底层控制层负责控制各变换器，控制方法 由中央管理层确定；中央管理层汇总系统信息进行模态判断，仅在需要切换时向底层下 发控制指令；各工作模态下变换器间协调配合，其中一个变换器控制母线。利用软件对 典型工作模态进行了仿真实现，结果表明，该协调控制方法可以实现多端口能量的灵活 流动和系统的稳定运行，具有可行性。

       设计、搭建适合本课题的硬件平台，在该平台上进行了本课题所提出的变换器级控 制方法实验和系统级协调控制方法在典型工作模态下的实验，实验结果证明了其有效性。
