wherein P is ij 、Q ij Satisfies the following conditions:
-c t，ij ·M≤P t，ij ≤c t，ij ·M

introducing the generated residual error into an objective function Obj;
under the constraint conditions of obeying a bus voltage difference inequality, a branch power transmission inequality and the like, solving a minimum value gamma of the generated residual error by using a weighted least square method through a computer CPLEX;
