A meter placement algorithm for the enhancement of state estimation function in an energy management system

A meter placement algorithm, that uses the variances of the state estimation (SE) errors as indices, is proposed to enhance the accuracy and robustness of the SE solutions. The algorithm provides a list of buses with low local redundancy in any observable area of a power network and a list of candidate measurements to reduce the SE error variances. The candidate measurements have the potential to increase the local redundancy around a certain bus on the list, thus improving its SE solution. Certain heuristics are applied to make sure that a minimum number of leverage points is introduced into the measurement set by the additional measurements. Test results on the IEEE 30 bus system are provided
