Optimal PMU Placement for Power System Dynamic State Estimation by Using Empirical Observability Gramian
Junjian Qi, Kai Sun, Wei Kang
In this paper the empirical observability Gramian calculated around the operating region of a power system is used to quantify the degree of observability of the system states unde…
