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.本数据集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) 一份基于MATLAB/SimPowerSystems仿真生成的互联微电网高分辨率细节图示； 2) 一份面向孤岛微电网小信号建模的MATLAB m文件，该孤岛微电网配置有2台基于下垂控制的电网成型型（grid-forming）分布式能源单元（Distributed Energy Resources, DERs）以及1台PQ控制型电网馈入式（grid-feeding）分布式能源单元，可用于开展小信号稳定性分析； 3) 一份包含2台基于下垂控制的电网成型型（grid-forming）分布式能源单元与1台PQ控制型电网馈入式（grid-feeding）分布式能源单元的孤岛微电网MATLAB slx文件，该文件可作为互联微电网开展仿真、暂态稳定性分析以及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。slx文件所需的参数均已在该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。
