This paper presents an optimization methodology based on tabu search to solve a unconstraint voltage regulators allocation problem in power distribution networks. The main objective is to find a balance between costs related to system planning and the fulfillment of power quality indexes. Analysis of the voltage profile and the objective function are carried out in the MATLAB environment for a typical...
This paper proposes an adaptive algorithm for non-pilot distance protection of power transmission systems. The proposed adaptive method compensates the infeed effect by estimating its current based on the short-circuit capacity. The performance analysis of the proposed technique was made from simulations in a 230 kV Brazilian transmission line using ATP/ETMP software. The adaptive technique was implemented...
This paper presents an extended impedance-based fault location formulation for unbalanced distributed generation systems. In recent years, distributed generation has become an efficient and economical alternative to produce energy. However, the high penetration of distributed generators changes the magnitude and direction of the fault currents affecting the accuracy of impedance-based fault location...
This paper presents an extended impedance-based formulation for fault location on deregulated electric power distribution systems. Distribution feeders are inherently unbalanced and traditionally radial. Deregulated distribution systems can have distributed generation, which changes the fault period power flow and decreases the accuracy of current state-of-the-art impedance based fault location formulations...
