A method for tuning a static var compensator for voltage control and reduction of harmonic distortion in a microgrid is presented in this paper. Electrical power distribution systems face a new scenario with an increasing number of distributed generation sources, nonlinear loads and more strict power quality requirements. In addition, it can be observed that there is a tendency for power systems to...
Most of the electricity distribution companies in Brazil, especially in rural areas, usually spend a long time to locate shunt faults in overhead lines. The major cause of the excessive time spent in the fault location process is the lack of appropriate tools. In spite of the existence of some tools that could be applied to aid the fault location, as permanent fault indicators, they are usually not...
This paper proposes an approach for optimal restoration of radial power distribution networks after an incident. This complex problem requires a decision-making process whose combinatorial nature can avoid the assessment of all possible solutions. Thus, the proposed approach is based on a binary coding particle swarm optimization (PSO) tool for handling the discrete variables associated with the switching...
This paper presents a new approach for distribution systems planning with thermal and wind distributed generation (DG). This approach determines the optimal placement of biomass-based thermal and wind distributed generation aiming at minimizing the energy loss, emissions and the total investment and operation costs, as well as improving the voltage regulation. The costs for the purchased energy from...
