In recent years, many of the researches are leaning towards distributed generation (DG) allocation studies, due to several technical benefits offered by DG units. The allocation of DG near the load center enhances the system voltage, minimizes the energy losses and line loading in distribution network. To upgrade the voltage profile, the allocation of capacitor is essential and it is quite economical, but its improvement of network performance is limited, because it will inject only reactive power. By examining the above downsides, non-dominated sorting genetic algorithm-II (NSGA-II) based optimization technique for allocation of DG and capacitor along with AVR is suggested in this paper. The proposed algorithm (NSGA-II) is implemented on standard IEEE 33 bus and 69 bus test systems. The result shows that the proposed methods gives better performance and improve the reliability of the distribution network.
