A novel algorithm for optimal meter placement to maintain network observability

This work presents a novel algorithm by which measurement system can be optimally determined and upgraded to maintain network observability. The proposed algorithm yields a measurement configuration that withstands any single branch outage or loss of single measurement, without losing network observability. The proposed algorithm is based on the measurement Jacobian and sparse triangular factorization in its numerical part and based on artificial intelligence in the decision making part. Details of the algorithm are presented using numerical example.
