摘要
暂态仿真和稳定性仿真在传统电力系统分析时几乎很少同时用于解决同一问题,而在微网以及含分布式电源的配电网中二者的应用出现了交集,如何合理地选择这两种仿真方法成为了亟待解决的问题。为此,详细阐述了暂态仿真和稳定性仿真的一致性和差异性,对微网中各种分布式电源和储能系统进行建模,采用Matlab/Sim Power Systems作为暂态仿真工具,DIg SILENT作为稳定性仿真工具,在统一的微网算例上进行了大量的仿真测试。通过对仿真结果的比较分析,说明了二者的一致性和差异性,同时也给出了其各自的适用范围,对于理解微网内部的各种动态过程和选择合理的仿真方法具有一定的指导意义。
The electromagnetic transient simulation and transient stability simulation are rarely performed simultane- ously for the calculation of traditional bulk power system, which is not true for the analysis and calculation of microgrid and distribution system with distributed generation.It is a common question for the user to choose a proper simulation tool.In this paper, the consistency and difference of the two type simulations is set forth in detail, and the dynamic mod- els of distributed generation and energy storage system in microgrid are built.They are applied to a typical microgrid test case, simulated respectively using DIgSILENT and Matlab/SimPowerSystems. The detailed comparisons are provided to verify their consistency and difference.At the same time, the application guidance for the two type simulations is given.It is helpful to understand the various transient processes and make a more reasonable choice for the related research.
