Abstract

This doctorate project aims at investigating the impacts of the inception of distributed generation over the power quality in distribution systems, from the viewpoint of the electromechanical oscillations that may be generated by this inception. The project intends to analyze the impacts of frequency variations (that are generated by these oscillations) over the operation of distribution systems and to define a criterion, based on interharmonic analysis, to quantify such impacts. The project also aims at developing a procedure to design damping controllers that could reduce the mentioned impact of the oscillations, quantified by the previously defined criterion. The development of this design procedure is intended to ensure that the inception of distributed generators in distribution systems does not degrade the quality of electrical energy supply in these systems.
