The invention provides a robustness state estimation method with large-scale wind power connection considered and particularly relates to a refined robustness least square state estimation calculation method. A weight function partition method of the IGG (Institute of Geodesy and Geophysics, Chinese Academy of Sciences) method is used for reference, a measurement type reference value is introduced into a weight function to conduct refined bad data distinguishing on wind power plant measurement, and meanwhile bad data reference factors are introduced in by using state estimation measurement pre-verifying information to solve the problem of bad data erroneous judgment caused by equipment parameters. According to the method, bad data weights in the state estimation calculation process can be dynamically adjusted, the problem of residual error pollution caused by the bad data weights is solved, and the state estimation precision of large-scale wind power connected into a power grid is improved.
