El objetivo es mejorar el desempeño y la calidad de la energía que suministran estos sistemas en su interconexión con la red eléctrica. En ese sentido, las variables de optimización son los parámetros del filtro y del controlador y se plantean dos funciones objetivo, una relacionada con la razón de atenuación armónica del filtro y otra con el desempeño del control, específicamente, la integral del error absoluto por el tiempo (ITAE, por sus siglas en inglés). Se resalta que la primera función objetivo depende de los parámetros del filtro, mientras que la segunda depende de los parámetros del controlador y también del filtro (planta); por lo cual, a diferencia de otros trabajos, la solución se aborda de manera conjunta y se resuelve utilizando optimización por enjambre de partículas (PSO, por sus siglas en inglés) a través de MatLab. Para la optimización, en primer lugar, se obtiene el modelo matemático del filtro y del controlador de corriente. Las restricciones, en el caso del filtro, se imponen en los parámetros de inductancia total, frecuencia de resonancia y resistencia de amortiguamiento; mientras que, en el controlador las restricciones buscan asegurar que las ganancias seleccionadas respeten el factor de amortiguamiento y ancho de banda propuesto. Derivado del proceso de optimización, en la parte final del documento se muestra la validación de los resultados obtenidos a nivel simulación, utilizando el esquema eléctrico de un inversor implementado en el software PSIM® de PowerSim®, donde se prueba el controlador y filtro diseñado ante cambios de potencia activa y reactiva. Con ello se demuestra la efectividad del diseño optimizado basado en PSO.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This work addresses the optimized design of the LCL filter and the internal current controller (PI), for a three-phase full-bridge inverter, of a distributed generation (DG) system. The objective is to improve the performance and quality of the energy supplied by these systems in their interconnection with the electrical grid. In this regard, the optimization variables are the filter and controller parameters; and two objective functions are established, one related with the filter harmonic attenuation ratio and other with the control performance, specifically, the integral time absolute error (ITAE). It is highlighted that the first objective function depends on the filter parameters, while the second one depends on the parameters of both the controller and the filter (plant); this is why, different to other proposals, here the solution is addressed in a combined way and is solved using particle swarm optimization (PSO) by means of MatLab. For the optimization, first, the mathematical model of the filter and the current controller is obtained. The constraints, in the case of the filter, are in the following parameters: total inductance, resonant frequency and damping resistance; while, in the controller, the constraints allow the selected gains to fulfill the proposed damping factor and bandwidth. As a result of the optimization process, in the final part of the document, the validation of the obtained results is shown, using the electrical schematic of an inverter implemented in the PSIM® software by PowerSim®, where the controller and filter designed is tested under active and reactive power changes; showing the effectiveness of the optimized design based on PSO.]]></p></abstract>
