Dynamic Modeling and Simulation of Interconnected Microgrids

This data package includes three useful files related with dynamic modeling, stability analysis and simulation of interconnected microgrids. 1) A high-resolution figure of interconnected microgrids with details simulated in MATLAB/SimPowerSystems. 2) A MATLAB m file of the small-signal model of the islanded microgrid with two droop-based (grid-forming) and one PQ-controlled (grid-feeding) DERs in which small-signal stability analysis can be done. 3) A MATLAB slx file of an islanded microgrid with two droop-based (grid-forming) and one PQ-controlled (grid-feeding) DERs, which is a fundamental module of interconnected microgrids for their simulations, transient stability analysis, and verification of designed controllers. The MATLAB m file is independent and can easily be run. However, required parameters of the slx file are provided in the m file. Therefore, running m file before executing simulation in slx file is necessary for a successful simulation.

本数据包包含三份与互联微电网的动态建模、稳定性分析及仿真相关的实用文件。1) 一份高分辨率的互联微电网示意图，其细节已通过MATLAB/SimPowerSystems仿真生成。2) 一份针对孤岛微电网小信号模型的MATLAB m文件，该微电网配置两台基于下垂控制的电网形成型（grid-forming）分布式能源单元（Distributed Energy Resource, DER）与一台PQ控制型电网馈入型（grid-feeding）分布式能源单元，可用于开展小信号稳定性分析。3) 一份对应上述孤岛微电网的MATLAB slx文件，该文件是开展互联微电网仿真、暂态稳定性分析以及已设计控制器验证的基础模块。该MATLAB m文件为独立文件，可直接运行。此外，slx文件所需的全部参数均已在该m文件中提供，因此若要顺利完成slx文件的仿真，需先运行该m文件。
