Optimal distribution substation locating in large distribution systems

A Hybrid Heuristic and Evolutionary Algorithm for Distribution Substation Planning

“…In recent studies conducted on SEP, [21]- [23] have used GA in optimization process. While SEP is investigated considering uncertainty loads and load splitting in [21], [22] proposed insensitive crossover and mutation operators that somehow ensure achieving optimal or close to optimal solutions; however, solution time has been multiplied.…”

“…The model considers total feeder costs, but inflation and interest rates are ignored. In [23], a binary GA is used to determine substation locations. In addition, substation service areas are defined based on loss characteristic matrix aimed at minimizing both loss and feeder length through the allocation process.…”

“…On the other hand, they are modeled in some research, which shows that total costs associated with the network feeders are effective in SEP results [20]- [23].…”

“…Total required costs for expanding MV feeders are considered in the second term of (1) [20]- [23]. In this term, C F ij (ρ j k ) is a variable and indicates the total construction/reinforcement cost of a feeder located between nodes i and j by conductor ρ k [22].…”

“…In this term, P loss ij indicates the power losses of a feeder located between nodes i and j and calculates through (4) [12], [19]- [23]. In (4), r ij is the resistance per length of feeder i−j, which is dependent on the selected conductor.…”
