Abstract

Back-To-Back (B2B) Voltage Source Converter (VSC) with AC-side LCL filters can be adopted for parallel AC-DC distribution links. In this paper, Grid-side Current Control (GCC) for the inner/fast control loops of the front- and backend power electronics are implemented in order to enhance the system performance against grid disturbances. Herein, a notch filter-based GCC scheme with a harmonic rejection control is proposed which is able to deliver attenuation to the LCL filter resonances while suppressing the harmonics in the grid-side currents originated when the AC voltages are distorted. The results obtained in MATLAB/SIMULINK and an experimental prototype show that the studied GCC method can successfully mitigate the influence of grid voltage harmonics, while providing a stable power control for the hybrid AC-DC distribution links.
