New Decentralized Control Scheme for a Dynamic Voltage Restorer Based on the Elliptical Trajectory Compensation.

In this paper, a novel decentralized control for a dynamic voltage restorer is proposed to deal with its captivity by improving the voltage quality of loads. The proposed technique controls the magnitude and the phase angle of the injected voltage to accomplish low-voltage ride-through based on the instantaneous calculations of voltages and currents and the application of elliptical compensation p...
