Definition

A numerical method that computes the most consistent estimate of the network state (normally bus voltage magnitudes and phase angles) from a set of redundant, noisy measurements and a measurement model, typically by solving a weighted least-squares (WLS) or equivalent estimation problem while examining observability and identifying bad data.
