Determining the Optimal Location and Number of Voltage Dip Monitoring Devices Using the Binary Bat Algorithm

Voltage dips represent a significant power quality problem. The main cause of voltage and short-term interruptions is an electrical short circuit that occurs in transmission or distribution networks. Faults the system are stochastic by nature dips. As faults can affect more customers than system, to reduce number dips, it not enough invest small part system. Only targeted investment whole (or large the) will Therefore, monitoring parts very important. ideal solution would be cover entire so (PQ) monitor installed on each bus, but this method economically justified. This paper presents advanced for determining optimal location dip measuring devices. proposed algorithm uses reach area matrix created short-circuit simulations, coefficient exposed area. Single-phase three-phase circuits simulated DIgSILENT software IEEE 39 bus test using international standard IEC 60909. After all potential positions, binary bat with used minimize objective function, i.e., determine Performance compared mixed-integer linear programming solved GNU Linear Programming Kit (GLPK).
