The trend in semiconductor developments has made the high-voltage direct current (HVDC) technologies based on voltage source converters feasible. This type of convertor has a number of potential advantages compared with “classic” HVDC, but deep analysis should be carried out before its integration in electric power system. In this paper, the results of

Potential interactions between VSC HVDC and STATCOM
2014 Power Systems Computation Conference, 2014This paper analyses the dynamic behaviour of a power system with both FACTS and VSC HVDC, in particular, possible potential interactions between a STATCOM and a VSC in a point-to-point HVDC link. The investigation considers different STATCOM locations and VSC control strategies.

HVDC cable modelling for VSC-HVDC applications
2014 IEEE PES General Meeting | Conference & Exposition, 2014This paper assesses the impact of commonly used cable modelling techniques on the accuracy and simulation speed of detailed VSC-HVDC models for a range of typical studies. The results show that the choice of cable model can have a significant impact on the accuracy of the VSC-HVDC models and that employing a higher fidelity cable model does not ...

Design and simulation of VSC-HVDC controller
2011 International Conference on Electrical and Control Engineering, 2011VSC-HVDC composed by full-controlled converter units is more flexible transmission schemes compared with traditional HVDC. It is necessary to study its control mode. This paper first analyzes the steady-state model of VSC-HVDC, then obtains the relationship among modulation wave phase δ, modulation degree m, active power and reactive power.

Supply passive networks with VSC-HVDC
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001In this paper, the steady-state model of the VSC-HVDC (voltage source converter based HVDC) system supplying a passive network has been developed. According to this model, the control strategy is presented. At the same time, the AC filter is designed based on analyzing the spectrum of the AC voltage generated by the VSC.

Dynamic modeling of a VSC-HVDC converter
2013 48th International Universities' Power Engineering Conference (UPEC), 2013The aim of this paper is to present a nonlinear dynamic model for Voltage Source Converter-based HVDC (VSC-HVDC) links that can be used for dynamic studies. It includes the main physical elements and is controlled by PI controllers with antiwindup. A linear control model is derived for efficient tuning of the controllers of the nonlinear dynamic model.

Review and development of MMC employed in VSC-HVDC systems
2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017The business case for MMC-HVDC is becoming popular in power transmission systems. Despite their superior potential compared to the AC and LLC-HVDC technologies, MMC-MTDC grid is yet to be efficiently realised in practice. Operation, control and modelling in such VSC-based schemes are arguably the most challenging research and development problems that ...

Margin calculation of VSC HVDC modules based on MMC
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016This paper deals with the reliability of VSC HVDC valve of MMC(Modular Multilevel Converter) based HVDC system. The final destination of this paper is to determine the redundancy of MMC valve. For this, several prediction methods were introduced, finally, the used method is “binomial failure method”.
