Abstract

Modular multilevel cascaded converter (MMCC) based high voltage direct current (HVDC) transmission is technically superior to other technologies, especially in case of connection of offshore wind power plants (OWPPs). Modelling challenges are faced by OWPP developers, who are not acquainted with detailed information regarding the internal behaviour of such complex devices.
This paper presents an investigation of the modelling requirements of the MMCC HVDC system, based on comparison between simulation results using a detailed HVDC representation in PSCAD/EMTDC and two less detailed models realised in EMT and RMS environments in DIgSILENT PowerFactory, respectively.
The results show that the simplified EMT/RMS models can be trusted for slow dynamic studies like those related to power control considered in this work. The results obtained from the detailed EMT model highlights the necessity for voltage balancing of the distributed capacitor voltages in the MMCC for both steady state operating conditions and during dynamic events such as step changes in the reference signals.
