In this paper, a mixed integer linear programming(MILP) formulation for robust state estimation (RSE) is proposed. By using the exactly linea rized measurement equations instead of the original nonlinear o nes, the existing mixed integer nonlinear programming formulation for RSE is converted to a MILP problem. The proposed approach not only guarantees to find the global optimum, but also does not have convergence problems. Simulation results on a rudimentary 3-bus system and several IEEE standard test sy stems fully illustrate that the proposed methodology is effective with high efficiency.
