Abstract

This research project aims to proposing and evaluating a method for computing the maximum loading point of power systems. The proposed method is based on the properties of the normal vector to the feasibility boundary, which is computed with the help of the load flow with step size optimization. The procedure is characterized by computing consecutive approximations of the maximum loading point from specified points within the infeaasible region. Since the feasibility boundary may not be convex, some of the specified points may fall within the feasible region. Then, a binary search based mechanism is used to drive the specified point back into the infeasible region. The reactive power limits from generators are taken into consideration. The idea is to obtain a robust, efficient and fast method, when compared to other methods proposed in the literature, to be used in real time operation environments. The proposed method will be tested through simulations involving the IEEE test systems and the Brazilian interconnected system. (AU)
