Efficient identification of binding inequality constraints in the optimal power flow newton approach

The paper presents a new technique for identifying the binding inequality constraints for the optimal power flow Newton approach. The technique is free of the need for user intervention, and reduces significantly the computational effort required by other methods. The algorithm is based on an efficient criteria for selecting and enforcing, at each iteration, a minimum number of active inequality constraints, and on obtaining a solution quickly and with less oscillations. The effectiveness of the proposed method is demonstrated by means of two sample systems.
