Abstract:-Micro grid distribution system planning is important to ensure that the growing need of electricity is met by the distributors. Planning starts at customer level, Individual power producers (IPPs) are the part of the power management system, as low power generated by the IPPs should reach the consumer through the shortest path in order to reduce the feeder line losses in low voltage distribution networks. Therefore, proper planning of the distribution system is very important to maintain continuity of power. While Planning Distribution System (DSP) the concept of graph theory can be used such that it involves selection of all possible paths through the graph between each pair of vertices. It compares the paths that exist between each pair of vertices until an optimal shortest path between two vertices is achieved. In this work selection of optimal shortest path is obtained using Johnson’s Algorithm. Several optimization techniques have been implemented to solve the problem of identification of shortest path. The work presented in this paper is yet another approach to address the same issue. To validate the proposed method, it is implemented on IEEE 8 bus system and simulation carried out using MAT LAB with results obtained for bidirectional power flow.
