- Distribution utilities aim to operate and plan their network in a secure and economical way. The prime focus of this work is to assist utilities by developing a new integrated approach which considers the impacts of system reliability in distribution system planning (DSP). This approach merges different problems together and solves them in a two-stage process, as follows: 1. cable routing and optimal location and number of reclosers; 2. optimal location and number of tie switches. The optimization algorithm is designed using a mixed integer programming (MIP). The developed approach has been tested on 2 distribution systems and for each system 18 different case scenarios have been conducted, making an overall of 36 simulations. Despite the complexity and the exhaustiveness of the problem, MIP converges and provides optimal solution within reasonable time for every scenario. The results show that without sufficient number of reclosers, drastically changing the cable layout can worsen the reliability. Moreover, the benefit of tie switch placement is very susceptible to the network outline (cable layout and number and position of reclosers). With more layout changes and bigger number of reclosers, the benefit of tie switches becomes more significant.
