Abstract

The paper presents possibilities of using distributed generation (DG) sources to mitigate voltage dips in LV grids due to short circuits in the MV and HV network. DG sources based on voltage source inverters (VSI) with pulse width modulation (PWM) control were considered. The DG sources generate active power depending on the depth of voltage dips under faults conditions. The compensation effect is shown for different DG source capabilities and different coupling between the LV and MV networks, i.e. the short circuit power of the distribution transformer. The PSCAD/EMTDC programme was used for analysis of system performance. Results of simulation for a study network are presented, which show the effectiveness of compensation
