IEEE Transactions on Industrial Electronics, 2019
This paper proposes an observer-based grid-voltage sensorless strategy that allows to implement the synchronization and control of an LCL grid-tied voltage source inverter. By using exclusively the measurement of the current injected to the grid, an observer estimates both fundamental positive- and negative-sequence components of the grid voltage ...

2012 IEEE International Symposium on Industrial Electronics, 2012
In this paper, a novel control scheme to mitigate the grid current distortion due to grid voltage disturbance is proposed for a grid-connected voltage-source converter (VSC) with inductor-capacitor-inductor (LCL) filters. Voltage unbalance and harmonics in three-phase systems cause the DC-link voltage ripples and the grid current distortion.

Reference current generation schemes for DFIG with unbalanced grid voltage
2014 IEEE 2nd International Conference on Electrical Energy Systems (ICEES), 2014This paper presents two improved schemes for reference current generation for improved dynamic performance of a Doubly-Fed Induction Generator (DFIG) subjected to unbalanced grid voltage. The focus is on estimating the oscillating power components in addition to the steady state power required from the generator without the need for sequence ...

An Effective Reference Generation Scheme for DFIG With Unbalanced Grid Voltage
IEEE Transactions on Sustainable Energy, 2014This paper presents a reference current generation scheme for improved dynamic performance of a doubly fed induction generator (DFIG) subjected to unbalanced grid voltage. The power and torque oscillations induced due to the unbalance in grid voltage are minimized using additional compensatory terms in the reference currents. The focus is on estimating

Control Strategy for VSC-HVDC under Unbalanced Grid Voltages
Applied Mechanics and Materials, 2017This paper describes the use of an unbalanced control strategy to solve the faults occur in AC grid side of High voltage direct current based on Voltage Source Converter (VSC-HVDC) system. This method divides the voltage and current parameters into negative-sequence and positive-sequence.
