摘要(Abstract)：

随着世界能源结构的转型,电力系统向着具有高比例新能源和高比例电力电子装备接入的新一代电力系统转型。建模是研究新一代电力系统动态特性与控制策略的基础。而现有电力系统软件存在自定义模型困难,不够灵活的缺点。难以适用于新一代电力系统的建模,基于此,文章开发了一种基于MATLAB/Simulink的新一代电力系统动态仿真工具箱。该工具箱可方便地实现含新能源和直流输电的新一代电力系统的仿真,具有可移植、模块化、开放式等优点,还可以充分利用MATLAB中的各种工具箱进行模态分析和控制器设计。文章在详细阐述该工具箱仿真建模核心思路的基础上,以风电经四端直流电网并网系统为例,通过对比所开发工具箱中建立的动态模型与在Simscape建立电磁暂态模型的仿真结果,验证所开发工具箱的正确性和准确性,最后,对带风电场的交直流混联系统的仿真分析结果表明,该工具箱能准确反映系统内各设备模型动态,方便地得到小干扰分析结果并进行振荡分析,适合于新一代电力系统的控制与动态分析方面的研究。
