Abstract

Distributed generation (DG) usage is increasing nowadays, specially in the wider sense of microgrids. Its technical impacts and restrictions are still under study, and in several aspects are kept almost untouched. One of these aspects is the small-signal stability of distribution systems in the presence of distributed synchronous generators (DSG). This paper deals with such problem, presenting a comprehensive small-signal stability study of a system under the specified conditions. The study considers two types of excitation control for synchronous generators: voltage and power factor. The focus, however, is on the latter, since it is the most widely used in distributed generators connected to distribution grids. Thus, a comparative analysis between these two control strategies is performed, allowing the investigation of their effects on the small-signal stability of a power distribution system (PDS). This comparative analysis is performed with respect to the characteristics of its electromechanical oscillation modes (EOM) under several DG penetration levels.
