Abstract :
Due to the high growth of DG installation in power systems, besides active power production, the DGs can also play an important role to fulfill reactive power requirements. Future smart grid is envisioned to be based on Distributed Resources (DR) and system security issues should be tackled by these units. In this paper, a method is used to rank the reactive power supported by DGs at different locations considering reactive power requirement in emergency conditions. Also, a new index is proposed in order to show the effect of DG´s reactive power output on voltage profile. In order to illustrate the effectiveness of the proposed method, simulation results of a low-voltage distribution system are reported and discussed.
