【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。
[Abstract]:Transient simulation and stability simulation are rarely used to solve the same problem in traditional power system analysis. However, the applications of transient simulation and stability simulation are intersected in microgrid and distribution network with distributed generation. How to select these two simulation methods reasonably becomes an urgent problem to be solved. Therefore, the consistency and difference between transient simulation and stability simulation are expounded in detail, and various distributed power generation and energy storage systems in microgrid are modeled. Matlab/Sim Power Systems is used as a transient simulation tool, Dig SILENT is used as a stability simulation tool, and a large number of simulation tests are carried out on a unified microgrid example. Through the comparison and analysis of the simulation results, the consistency and difference between the two are illustrated. At the same time, their respective application ranges are also given, which has a certain guiding significance for understanding various dynamic processes within the microgrid and selecting reasonable simulation methods.
