The effect of dispersed generation on power quality in distribution system

This paper analyzes the influence of dispersed generation (DG) on voltage quality in MV networks and summarizes problems considered of general interest relating to the power quality of dispersed generation. We are interested in voltage fluctuations, flicker, harmonic distortion, interharmonic distortion, and the effect of dispersed generation on ripple control signals. The influence of DG on voltage stabilization, line losses, and short circuit impedance are also investigated, and case studies in real systems are presented.
