Optimized loads for damping harmonic propagation

Shunt harmonic impedances have been proposed as an attractive means for mitigating the propagation of harmonic pollution. The effectiveness was shown for linear power systems with current source polluting loads. In this paper, an extension of the concept for a typical nonlinear polluting load (a capacitively smoothed rectifier) is presented. It is shown that the proposed method is especially effective in the case of power system resonances.
