A new algorithm to find the optimal numbers and locations of power quality monitors

This paper proposes monitor positioning algorithm which determines the optimal number of monitors and their locations. The bus incidence matrix is modified using monitor locations. The principles of monitor positioning are suggested and the weighting factors of each component are defined following these principles. Ambiguity indices are newly suggested to evaluate the monitor locations in terms of topological ambiguity. Finally, the overall algorithm for monitor positioning is developed and applied to IEEE 37 node test feeder. It realizes the expert´s knowledge on monitor positioning into sophisticated automatic computing algorithm.
