Parabolic PWM for Current Control of Voltage-Source Converters (VSCs)

IEEE Transactions on Industrial Electronics, 2010
A novel parabolic carrier pulsewidth modulation (PWM) method is proposed in this paper for direct current control in a voltage-source converter (VSC). This method employs a pair of parabolic PWM carriers (a positive one and a negative one) to determine the switching states of the two switches in a converter phase leg while limiting the current tracking

Reachability analysis for a grid-connected voltage-sourced converter (VSC)

2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018
To analyze a system accurately, all of its parameters, initial conditions, and inputs are needed; however, finding their precise value is not possible in practice. In addition, uncertainty of a system cannot be considered in conventional methods for system analysis.

Square of Voltage Out-Loop Based Feedback Linearization Control of Voltage Source Converter (VSC) in SMES

Advanced Materials Research, 2013
To improve the response characteristic of the VSC in SMES (Superconducting Magnetic Energy Storage) with wide load disturbance, a new square of voltage out-loop based feedback linearization control strategy is proposed for the control of VSC. The input variable was controlled by a combining of square of voltage out-loop based direct voltage control and

Voltage Source Converter (VSC) HVDC for bulk power transmission - technology and planning method

9th IET International Conference on AC and DC Power Transmission (ACDC 2010), 2010
As the value of additional functionality of any new power technology is very case dependent, it is not possible to make general comments on the economics of VSC HVDC applications for bulk power transmission without considering alternatives. Therefore, the paper presents a methodology which can be used to evaluate different investment options, based on ...

STATCOM model in EMTP RV using hysteresis current controlled voltage source converter (VSC)

Canadian Conference on Electrical and Computer Engineering, 2005., 2006
In this paper, a static compensator (STATCOM) model in EMTP RV of a voltage source converter (VSC) is presented. The STATCOM is connected to the end of a transmission line. The DC/AC conversion is obtained by using pulse width modulation (PWM) based on a current hysteresis controller.

DC overvoltage control during loss of converter in multiterminal voltage-source converter-based HVDC (M-VSC-HVDC)

IEEE Transactions on Power Delivery, 2003
Security requires that a system continues to function even when any one subsystem fails. A multiterminal HVDC system consists of N voltage-source converters (VSCs) exchanging power through a DC network. When any one converter is lost, before the surviving (N-1) converters have time to re-establish a new power balance, the excess DC power can produce ...
