Two Stage Methodology for simultaneous placement and sizing of distributed generation and capacitors using Artificial Bee Colony in order to reduce losses and increase the voltage stability

In this paper, a new approach is proposed to simultaneous placement of distributed generation and capacitors. This method is contained two stages using two sensitive index Sv and Ss. Sv and Ss are calculated according to nominal voltageand network losses. In the first stage, candidate buses is determined for installation DG and capacitors according to Sv and Ss, Then in the second stage, placement and sizing ofdistributed generation and capacitors are specified using Artificial Bee Colony (ABC). The proposed algorithm is tested on 33-bus and 69-bus radial distribution networks. The test results indicate good performance of the proposed method.
