Synchronous Generator Emulation Control Strategy for Voltage Source Converter (VSC) Stations
IEEE Transactions on Power Systems, 2015The voltage source converter (VSC) station is playing a more important role in modern power systems, but the dynamic behavior of the VSC station is quite different from that of the synchronous generator. This paper presents the synchronous generator emulation control (SGEC) strategy for the VSC-HVDC station.

Parabolic PWM for Current Control of Voltage-Source Converters (VSCs)
IEEE Transactions on Industrial Electronics, 2010A 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), 2018To 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.
