Investigation of Weight Matrix and Average Probability of Observability Index in Optimal Placement of Phasor Measurement Units

This paper presents an optimization model for the calculation of the minimum number of phasor measurement units in complete observability electrical power networks. Since the phasor measurement units with more route measurements have higher costs, investigation the weight matrix is recommended. In conditions in which matrices with the same weight are available, in order to select the optimum result, calculation of average probability of observability index is suggested. The solution method represented in this paper is simulated in MATLAB© software environment on ٩ bus IEEE standard network using linear integer programming. The results indicate the optimum placement of phasor measurement units with less cost and efficient average probability of observability index in this issue.
