This study presents an analytical approach for optimal siting and sizing of distributed generation (DG) in radial power distribution networks to minimise real and reactive power losses. For this purpose, suitable analytical expressions have been derived which are based on change in active and reactive components of branch currents cause by the DG placement. This method first determines the DG capacity causing maximum benefit at different buses, and then selects the bus as the best location for DG placement which corresponds to highest benefit. The proposed method is applicable for sizing and siting of single as well as multiple DG units. Moreover, the proposed method requires only the results of base case load flow to determine the optimal size of DG unit(s). The proposed method is tested on 33-bus and 69-bus radial distribution test systems. The results obtained by this proposed method validate the suitability and importance of proposed analytical method to determine the size and site of DG unit(s).
