L_p State Estimators for Power Systems

摘要

The widely used method of least squares for state estimation is revisited. The commonly used least squares philosophy is based on the L_2 Hoelder norm. The L_1 and L_∞ norms are considered for applications in power engineering. The effects of outliers in measurements and multicolinearity on state estimation are studied. An application in parameter estimation for synchronous generators is given as an example.
