The advanced operation of future electricity distribution systems is likely to require significant observability of the different parameters of interest (e.g., demand, voltages, currents, etc.). Ensuring completeness of data is, therefore, paramount. In this context, an algorithm for recovering missing state variable observations in electricity distribution systems is presented. The proposed method exploits the low rank structure of the state variables via a matrix completion approach incorporating prior knowledge in the form of second order statistics. Essentially, the recovery method combines nuclear norm minimization with Bayesian estimation. The performance of the new algorithm is compar..
