Dynamic response of distributed synchronous generators on faults in HV and MV networks

Connection of distributed generators (DG) on existing power distribution networks requires solution of technical, economical and regulatory issues. A brief description of current status of DG in Bosnia and Herzegovina, with special attention to the technical impact of integration of small hydro power plants with synchronous generators, is given in this paper. Dynamic response of DG (namely small hydro power plants with synchronous generators) on disturbances in HV and MV networks is analyzed in detail. Simulations of DG dynamic response are performed using free, open-source MATLAB/PSAT software package on a simple test model of distribution network with DG. Several scenarios are studied. Finally, areas for further research are identified and presented.
