简介
Under unbalanced grid conditions, the control of the instantaneous active and reactive power causes the injection of unbalanced currents into the utility grid. Especially, the power oscillating terms that appear due to the interaction between different sequences voltages and currents remains an important issue. This problematic requires the design of consistent arrangements to calculate the current references that should be exchanged with the grid by the grid side converter (GSC). This paper introduces a mechanism of negative-sequence injection based on the control of d-q currents coordinates. Besides, a comparison study of the design of current controllers, using a generic vector approach, to enhance unbalance-fault ride-through capability of dispersed generation has been proposed. The performance of entire control system is evaluated by time domain simulations with MATLAB/Simulink. The achieved results …
