| Abstract: | State estimation is an important part of the energy management system of the power system.As the weighted least squares estimation does not have robustness,robust estimation theory was proposed.This paper introduces the definition,goals,and types of the robust estimation and reviews both classical and newly emerging power system robust state estimation methods.The classical methods mainly include M estimation,GM estimation,and high break-down point estimation.The new methods mainly include innovation graph ... |
