Nowadays, most of the equipment used in the industries are mainly based on semiconductor devices and microprocessors and hence these devices are very sensitive to voltage disturbances. Among power disturbances, voltage sags are considered as the most frequent types of disturbances in the field and their impact on sensitive loads is severe. However, to assess voltage sags, installation of power quality monitors (PQM) at all system buses is not economical. Thus, this study is carried out to develop a power quality monitor positioning algorithm to find the optimal number and placement of PQMs in both transmission and distribution systems. In this proposed approach, first, the concept of topological monitor reach area is introduced. Then the genetic algorithm is used in finding the optimal number of PQMs. Finally, to optimally place the identified number of PQMs, all possible combinations of those PQMs in the power system are evaluated using two novel indices namely, monitor overlapping index and sag severity index. The proposed algorithm has been implemented and tested on the IEEE 30-bus and the IEEE 34-node test systems to show effectiveness of the proposed method to both transmission and distribution systems.
