Optimal Conductor Size Selection in Distribution Systems Using the Harmony Search Algorithm with a Differential Operator

Multi-conductor feeder design for radial distribution networks

“…The developed algorithm, in this paper yielded better results compared to HSDE algorithm [4] when applied on the 85-node system. Other test systems not presented due to space limitation are investigated reaching same conclusion.…”

“…To demonstrate the accuracy and convergence speed of the proposed approach the IEEE 69-node [12] and 85 node [4] radial distribution networks are considered. Moreover the conductor sizes available in inventory for the 69-node system are given in Table 1 and for the 85-node system they are given in Table 4.…”

“…Optimizations resulted in using seven types of these conductors. Further PM is applied on an 85-node system, using eight different sizes of ACSR conductors from [4] and optimizations resulted in using three types of these conductors. The simulation results from PM are compared with results using HSDE approach [4].…”

“…However no evidence is given on compliance with voltage constraints. In [4], the harmony search algorithm with a differential operator inspired by differential evolution (HSDE) is used to solve the optimal conductor size selection problem. The objective function is modeled as a problem that minimizes the sum of capital investment and capitalized energy loss cost.…”

Adaptive Power System Stabilizer Design Using Optimal Support Vector Machines Based on Harmony Search Algorithm

“…HS is simple in concept, has fewer parameters, and is easy to implement [25]. It has been successfully applied to various optimization problems, such as optimal conductor size selection in distribution systems [26] and economic load dispatch [27], distribution system reconfiguration [28], and solving optimal power flow problems [29]. These works show that the HS algorithm is superior to other algorithms, and accordingly, the HS algorithm is used for the tuning of SVM parameters in this work.…”
