A fuzzy state estimator based on uncertain measurements
TL;DR: In this article, a fuzzy linear state estimation model is employed, which is based on Tanaka's fuzzy linear regression model, for modeling uncertainty in power system state estimation, and the estimation process is described by fuzzy numbers with a triangular membership function that has middle and spread value reflected on the estimated states.
