Abstract

Installation of power quality monitors (PQMs) at all buses in a power distribution network is uneconomical and it needs to be minimized. This paper presents a PQM positioning technique which finds the optimal number and location of PQMs in power distribution systems for voltage sag detection. The IEEE 34-node and 69 bus test systems were modeled in DIgSILENT software to obtain the topological monitor reach area matrix for various types of faults. Then, an optimization problem is formulated and solved using genetic algorithm to find the minimum number of PQMs in the distribution system which can guarantee the observability of the whole system. Finally, the sag severity index has been used to find the best location to install monitors in the distribution system.
