基于OpenDSS的智能配电网仿真与模拟平台及其应用

OpenDSS-Based Simulation and Modeling Platform of Smart Distribution System and Its Application

OpenDSS仿真系统为含分布式电源及储能装置的配电网提供仿真分析和规划研究平台,并为智能配电网提供一个开放共享的研究平台。从建模方法、仿真功能和用户自定义扩展应用3个方面介绍了OpenDSS的特点和优势。在建模方法上,该平台考虑了配电网的不对称特性,并提供了丰富的配电网控制模型;在仿真功能上,提供了快速潮流计算功能,并开发了一系列仿真方法;在用户自定义扩展上,基于COM接口,实现了OpenDSS和其他仿真软件的互动。针对上述功能和特点,以及给出的应用实例,希望能够对推动智能配电网快速仿真与模拟技术在中国的应用与发展起到一定的作用。

OpenDSS simulation system can assist the simulation analysis and planning research for distribution grid that contains distributive power sources and energy-storage devices and provide an open and shared research platform for smart distribution grid.The features and advantages of OpenDSS are introduced from the three aspects including modelling method,simulation function and user-defined application.For the modelling method,the OpenDSS takes the asymmetric features of distribution system into account and divides the elements into four classes with the multi-phase modelling method.For the simulation method,the OpenDSS provides a fast power flow method based on which many other capacities are realized.For the user-defined application,OpenDSS can interact with other simulation software based on the COM interface.Some simulation cases are given to show the functions mentioned above for the purpose of promoting the application and development of distribution fast simulation and modelling （DFSM） in China.
