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 ...

VSC-HVDC Station With SSSC Characteristics
IEEE Transactions on Power Electronics, 2004Commercial installations of voltage-source converter-high voltage direct current (VSC-HVDC) are now in service as asynchronous link and as underwater/underground DC transmission. The research reported in his paper is directed to providing VSC-HVDC with synchronizing power and damping power so that after a transient the steady-state is reached in ...

In the case of VSC-based HVDC transmission systems, the transfer of power is controlled in the same way as in the case of a classic HVDC transmission. The inverter side controls the active power, while the rectifier side controls the DC voltage [33, 56]. With classic HVDC, the reactive power cannot be controlled independently of the active power.

The system considered in this book is given in Fig. 5.1. The HVDC system consists of two VSCs connected via a DC link. The control of converter VSC-1 is done by using DC voltage control, whereas the control of converter VSC-2 is done by active power control. In this chapter, the steady-state and transient behavior of control schemes in normal and fault

Towards interoperability in VSC-HVDC Networks
2022High voltage direct current (HVDC) transmission infrastructure plays a key role in enabling the integration of renewable energy sources (RES). Moreover, the grid of the future is expected to have a high penetration of power electronics interfaced devices (PEIDs), which play a fundamental part in the energy transition towards carbon neutrality.

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.

Stability analysis of multi-infeed HVDC system applying VSC-HVDC
IEEE PES General Meeting, 2010This paper presents a general model of dual infeed HVDC system applying VSC-HVDC, which can be used as an element in large multi infeed HVDC system. The model may have different structure under different grid faults because of the action of breakers. Hence power flow of the system based on this model is analyzed under steady state and different kinds ...

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.
