Abstract

The authors propose an algorithm of optimal meter placement for the state estimation of power systems, which minimizes the total investment cost subject to a constraint of state estimation accuracy. The solution procedure is developed on the basis of the sequential meter addition/elimination method by reflecting the cost of individual meter installation and its contribution to the state estimation accuracy in the probabilistic sense. The sensitivity of the performance index to each meter installation is efficiently circulated with the use of recursive formulae. Selection ranking in the addition-elimination process is set up in terms of the performance index sensitivities.<>
