Operation of a voltage source converter at increased utility voltage
IEEE Transactions on Power Electronics, 1997The operation of a voltage source converter (VSC) with regeneration capability, controllable power factor, and low distortion of utility currents is analyzed at increased utility voltage. Increase in the utility voltage causes a VSC to saturate and enter a nonlinear mode of operation.

Adaptive Grid-Synchronization Based Grid-Forming Control for Voltage Source Converters
IEEE Transactions on Power SystemsThis letter presents a grid-forming control with adaptive grid-synchronization capability for voltage source converters (VSCs). The proposed control has both phase-locked loop (PLL) and power synchronization loop (PSL), which makes it exhibit hybrid ...

Voltage Source Converters to Improve the Operation of the Micro-grid
2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008The paper discusses the use of the 'Micro-grid' concept to integrate renewable energy generation into the distribution network. In essence, a Micro-grid consists of bundled renewable micro sources and loads connected together by fast acting power electronics. Energy storage and low-bandwidth supervisory control is often added.

Exact Modeling of the Voltage Source Converter
IEEE Power Engineering Review, 2001A discrete time, linear time varying model of the three-phase voltage source converter (VSC) is developed. The model is employed to determine the steady state operating characteristics of a VSC taking all ac-dc side harmonic interactions into account. The procedure is based on an exact closed form solution of the system equations and does not rely on ...

Voltage Dip Mitigation Using Shunt-Connected Voltage Source Converter
IEEE Transactions on Power Electronics, 2006In this paper, a Voltage Source Converter (VSC) connected in shunt with the grid to mitigate voltage dips for sensitive processes is presented. The VSC maintains the magnitude of the grid voltage at the connection point constant by injecting reactive power to compensate for the voltage dip. This is achieved by using a cascade controller, constituted by
