The Transmission Expansion Planning (TEP) is still a highly complex, combinatorial, non-linear and non-convex problem, where more accurate models and more efficient optimization tools are needed. The purpose of this work is to solve the static Transmission Expansion Planning (TEP) problem through the Biogeography Based Optimization (BBO) technique using an AC model, for the simultaneous expansion...
The introduction of energy storage devices represents an important element for supporting the operation of distribution networks. Considering the presence of renewable energy sources, the use of these devices provides ancillary services and energy balance flexibility to the network. This work presents a mixed integer second order cone programming model for solving the problem of allocating energy...
In this work, the performances of robust load flow methods are compared, in special when applied to ill-conditioned systems. In such cases, the iterative process may diverge or oscillate when standard Newton Raphson (SNR) based load flow calculation methods are used. Some known approaches to solve these systems are the Load Flow with Step Size Optimization (LFSSO) and Continuation Power Flow (CPF)...
In this paper a fast, practical maximum loading point (MLP) calculation method is presented. The calculation process is based on the properties of the normal vector to the feasibility boundary computed close to MLP, which is calculated through a load flow method with step size optimization (LFSSO). Moreover, a practical procedure is added to the overall calculation process to include the operator's...
