This paper presents a novel mixed integer linear programming‐Newton approach for solving constrained AC power flow problems, based on a recently proposed linear programing‐Newton method. The linear programming‐Newton method overcomes some defic

O método Newton-PL é um complemento do método de Newton clássico. Possui vantagens teóricas em relação ao método de Newton pois sua convergência não pressupõe unicidade local das soluções ou mesmo a diferenciabilidade das equações do s

The objective of this paper is to propose a novel augmented Lagrangian approach for solving the Optimal Reactive Dispatch (ORD) problem in electric power systems, which consists in a large nonconvex Nonlinear Programming (NLP) problem. Given an NLP p

The estimation of steady-state voltage stability limits represented by the critical value of a voltage stability index (VSI) in power flow-based electric energy system models may be a very difficult task, which might render their applicability imprac

Security margins have been reduced in restructured and deregulated power systems, and as a result, these systems have been operated close to their security limits. Therefore, it is of utmost importance that power system operation be tracked in a real

This paper proposes an approach of optimal sensitivity applied in the tertiary loop of the automatic generation control. The approach is based on the theorem of non-linear perturbation. From an optimal operation point obtained by an optimal power flo
