Modelling, Control and Simulation of VSC-HVDC Systems

2018 15th International Multi-Conference on Systems, Signals & Devices (SSD), 2018
The world is facing today a global energy transition challenge since developed countries need more energy for their economy growth in a framework of limited and poorly distributed energy resources. The Voltage Source Converter for High Voltage Direct Current (VSC-HVDC) is the most appropriate and efficient technology leading to accommodate more ...

Potential interactions between VSC HVDC and STATCOM

2014 Power Systems Computation Conference, 2014
This 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, 2014
This 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 ...

Towards interoperability in VSC-HVDC Networks

2022
High 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.

Design and simulation of VSC-HVDC controller

2011 International Conference on Electrical and Control Engineering, 2011
VSC-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), 2001
In 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), 2013
The 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), 2017
The 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 ...

Nonlinear modeling and control of a VSC-HVDC transmission systems

2016 24th Mediterranean Conference on Control and Automation (MED), 2016
This paper presents a new modeling and control strategy of VSC-HVDC transmission system in order to improve system damping oscillations, and enhancing transient and voltage stability. This control strategy is based on a linear and bilinear state space deviation models.
