A study on HVDC user-defined modeling in PSS/E

Power System Simulator for Engineering (PSS/E) is one of the most extensively used power system simulation software in the globe. In this paper, by modeling a high-voltage direct-current (HVDC) transmission system, an in-depth study of its user-defined function in PSS/E is illustrated. Furthermore, comparing the simulation curves of user-defined HVDC in PSS/E with those simulated by PSCAD/EMTDC and PSD-BPA, the correctness of the HVDC user-defined model, the feasibility as well as the practicability of PSS/E's user-defined function are validated. Similarly, the modeling method proposed in this paper provides guidance for modeling of other complex two-terminal and multiport components applied to power systems. The experimental results prove the accuracy of the HVDC user-defined model as well as the practicability of the method, by which the feasibility of two-terminal component modeling in PSS/E is also verified.
