Optimum Substation Placement and Feeder Routing Using GA-MST

Distribution system as an important division of the electric power system as one of the most complicated systems created by the mankind. The problem of distribution system planning is to find the optimum location and sizing of the substation and the optimum feeder configuration to connect the consumers to the distribution substation and distribution substation to the primary substations. This paper proposes an algorithm to find the optimum distribution substation placement and sizing by utilizing the GA algorithm and optimum feeder routing using modified MST. The proposed algorithm has performed on distribution network model with 250 consumers form MV to LV levels. The result indicates that proposed algorithm is able to achieve the optimum number of substation in adequate placement and sizing with optimum feeder routing. The problem constraints of distribution network planning are considered as a part of objective function.
