Özet
Making decisions on expansions of the power system as a result of the growth in electricity demand is essential in order to maintain a reliable network. Since substations take on the role of the intermediate link between electricity supply and demand, substation expansion planning (SEP) is one of the most important planning studies. In this study, the SEP problem is merged with the different geographical configurations of the zones within a mixed integer linear programming framework. The voltage profile and power losses are integrated into the SEP problem by using approximate lumped model of the zones. The effect of voltage constraints and the cost of feeder loss on the SEP problem is investigated and the comparison between the SEP problem with rectangular zones and with triangular zones is performed to show the impact of different geographical configurations on the investment decisions.
