VSC-HVDC Control System

2020
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.

Performance analysis of paralleled VSC-HVDC systems

2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016
This paper presents a detailed study of the VSC-HVDC system along with the related cases of paralleling two similar VSC-HVDC systems. A basic VSC-HVDC system is designed with controllers on either side of the system. The system is further expanded by connecting a similar VSC-HVDC system in parallel for enhancing the reliability.

DC line protection for VSC-HVDC system

2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012
Voltage source converters based HVDC (VSC-HVDC) systems involving overhead transmission lines are prone to severe over-currents and over-voltages during dc line faults. This necessitates the operation of the system with some kind of protective devices to overcome the effects of dc line faults.

Fault Current Limiters for VSC-HVDC systems

10th IET International Conference on AC and DC Power Transmission (ACDC 2012), 2012
Fault Current Limiters (FCL) limit fault current levels to a more manageable level, this way it becomes possible to increase the transmission ratings of an electrical system, without changing the equipment. Thus, the existing equipment is able to handle the new currents and protect properly the system.

Integration of wind farm to VSC-HVDC system

2017 International Conference on Smart grids, Power and Advanced Control Engineering (ICSPACE), 2017
Renewable energy resources are playing an important role in reducing the energy crisis. One of the important resources is being wind energy systems. Most of the times, offshore wind power is transferred to the main land grid through VSC-HVDC transmission system due to its advantages.

Overview on VSC-HVDC Systems Based on PV

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
As a result of the rapid development of DC charging and the extensive use of electronic devices, the number of DC loads has increased dramatically. Loads have the characteristics of AC and DC coexist. At the same time, there are many distributed power sources in microgrids, such as PV, wind power generation, and so on.
