The Box algorithm is an important direct searching method for optimal engineering design, which is applicable toresolve optimization when the object function can't be given explicitly. The allocations of reactive sources and the control ofreactive facilities create a non--linear discrete VAR optimization problem and the object is an inexplicit function of the controlvariables. So a VAR allocation optimization based on Box algorithm is presented. Techniques for improving convergence arealso discussed such as penalty functions dealing with function constrains, repeat iteration and Bays--Durham shuffle basedcombination generating random number. The IEEE 6. 14. 30 node systems and other power systems are utilized todemonstrate the validity of the proposed approach. Computational test proves the approach can be applied to real large-scalesys terns.
