- Abstract
Introduction--The DC/AC conversion systems currently used in multiple applications such as alternative energy sources involve power quality problems due to voltage regulations and deformations such as those caused by harmonic distortion. Objective--To develop a prototype that, through a multi-objective genetic algorithm, allows optimizing the energy quality of three-phase inversion systems through the use of multilevel converters. Methodology--The prototype to be used in the power conversion is defined, the output voltage is modeled mathematically, the optimization multiobjective genetic algorithms are developed, the prototype is implemented and its operation is validated. Results--The algorithm developed and implemented in the developed prototype mitigates the power quality phenomena associated with short and long duration variations such as swell, sag, undervoltage and overvoltage, avoids the presence of voltage fluctuations and presents a lower harmonic content, in all cases 1% Conclusions--The implemented prototype optimizes the power quality of three-phase power supply systems through the use of a multilevel inverter, avoiding the presence of power quality phenomena.
