Due to the restructuring in electricity market and environmental concerns penetration level of DG unit has been increased rapidly. It is also playing a significant role in minimization of line losses of a power system network. So it is very important to define the size and location of distributed generation unit to be allocated in a power system network. On the other hand, due to radial distribution systems basic inherent features such as radial structure, a wide range of 𝑿/𝑹ratios, and a large number of nodes. The optimal sizing and sitting problem of a DG unit cannot be determined by the conventional techniques, which are used for transmission systems. A novel method for the estimation as well as minimization of losses in a radial distribution system with DG unit has been presented in this paper. An algorithm is presented in this paper to obtain the optimum position of DG units in the distribution network based on the available amount of DG using Fuzzy logic. Test results on a 34-bus system reveal the superiority and simplicity of the proposed algorithm. It is observed that placement of DG at appropriate location results in loss reduction and improved voltage regulation of the system.
