本文提出了一个全面的状态空间动态模型的未来配电系统的即插即用接口的分布式可再生能源和分布式储能设备。该系统被称为未来可再生电能输送和管理（FREEDM）系统，包括多个固态变压器（SST）以及连接到分布式网络中每个SST的负载，发电和存储。该系统允许可再生能源发电的高渗透率，并在配电层面进行储能。基于物理的70阶状态空间平均模型首先开发考虑的物理和控制器的属性的单SST FREEDM系统沿着其分布组件。然后将该基本模型扩展到多SST FREEDM系统，对整个系统的可行性和动力学行为进行分析，这对于确保系统功率平衡至关重要。多个SST的全平均模型已被纳入IEEE 34总线分布测试平台的系统的缩放分析。
This paper presents a comprehensive state-space dynamic model of a future power distribution system for plug-and-play interface of distributed renewable energy resources and distributed energy storage devices. The system, called the future renewable electric energy delivery and management (FREEDM) system, comprises of multiple solid-state transformers (SSTs), and load, generation, and storage connected to each SST in a distributed network. The system allows for high penetration of renewable generation with energy storage at the distribution level. A physics-based 70th-order state-space average model is first developed considering the physical and controller properties of a single-SST FREEDM system along with its distribution components. This fundamental model is then extended to build a multi-SST FREEDM system for feasibility and dynamics behavior analysis of the entire system, which is essential to ensure system power balance. The full average model with multiple SSTs has been incorporated in an IEEE 34 bus distribution testbed for a scaled analysis of the system.
