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 ...

Nonlinear modeling and control of a VSC-HVDC transmission systems
2016 24th Mediterranean Conference on Control and Automation (MED), 2016This 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.

A Control Strategy of a VSC HVDC System for Power System Enhancement
2009 Second International Conference on Emerging Trends in Engineering & Technology, 2009Voltage Source Converter (VSC) based HVDC is the most recent HVDC technology with extruded DC cables in small and medium power transmission. VSC-HVDC converters include Insulated Gate Bipolar Transistors (IGBT'S) and operated with high frequency Pulse Width Modulation (PWM) in order to get high speed control of both active and reactive power[1][2 ...

Overview on VSC-HVDC Systems Based on PV
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018As 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.

Performance analysis of paralleled VSC-HVDC systems
2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016This 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.

Integration of wind farm to VSC-HVDC system
2017 International Conference on Smart grids, Power and Advanced Control Engineering (ICSPACE), 2017Renewable 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.

DC line protection for VSC-HVDC system
2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012Voltage 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.

A filter design methodology of a VSC-HVDC system
2013 IEEE International Autumn Meeting on Power Electronics and Computing (ROPEC), 2013This paper describes a methodology for the design of AC and DC filters of a VSC-HVDC system, based on mathematical calculations and simulations in Matlab Simulink®. The methodology is implemented in a ± 125kV and 200MW VSC-HVDC system. The 3D-SVPWM modulation technique is used to control the VSC converters of the system as a method to reduce high ...
