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

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.
