Summary:This article proposes a new approach to solve the optimal reactive dispatch problem, based on Newton approach and the primal-dual logarithmic barrier method. A Lagrangian function is associated with the modified problem. The first-order necessary conditions for optimality are fulfilled by Newton's method and by updating the penalty and barrier terms. The proposed approach does not require the set of binding constraints to be identified and can be utilized from an infeasible starting point. The effectiveness of the proposed approach has been examined by solving the Brazilian 53-bus and 662-bus systems.
