Abstract: To enhance the power quality and reliability of electric power delivered to the end users, the electric distribution system is utilising the custom power devices. The power loss and voltage profile evaluates the performance of distribution system. In this paper a heuristic optimisation technique known as firefly algorithm is applied for the optimal location and sizing of dynamic voltage restorer (DVR). The steady state model of DVR is derived to use in forward/backward sweep load flow method. The performance of the proposed method is tested on IEEE 33 bus and 69 bus Radial Distribution systems by using MATLAB software. The obtained results are compared with immune algorithm. The proposed method boost up the voltage profile minimised the power loss and the installation cost of DVR.
