“…Las microrredes han sido un tema de investigación bastante extenso, ya que la integración al sistema eléctrico implica m últiples desafíos técnicos, desde la gestión de potencia, has-ta sobrepasar adecuadamente las fallas y/o perturbaciones en el sistema (Sen and Kumar, 2018), (Castro et al, 2019b). El modo operativo de la microrred define el objetivo de control de los convertidores para su óptimo funcionamiento, por lo que estos sistemas deben realizar la gestión de potencia de los generadores, del consumo de los dispositivos de almacenamiento y de los intercambios con la red eléctrica, y al mismo tiempo operar en modo aislado y soportar las cargas que se encuentren conectadas (Hou et al, 2018), (Montoya et al, 2018).…”

Las microrredes son fundamentales ya que permiten la integracion local de unidades de generación basadas en fuentes renovables, sistemas de almacenamiento y usuarios de energía electrica. Sin embargo, para un correcto funcionamiento, el control de la microrred es un aspecto fundamental, por lo que en este trabajo se propone, de forma didactica, una estrategia de implementación sencilla para aquellos casos en los que no se disponga de la descripcion matemática o modelo del sistema. El aporte del trabajo consiste en la propuesta de una estrategia detallada para el diseno del control jerárquico de convertidores de fuente de tensión basada en matematica difusa, que considera el funcionamiento de la microrred como aislada o conectada a la red principal. La implementacion propuesta y el análisis de los resultados obtenidos muestran que la estrategia de control jerárquico propuesta tiene un desempeno satisfactorio. Además, esta estructura de disño es escalable, robusta, aplicable en sistemas lineales o no lineales y rapidamente implementable en sistemas físicos

“…These studies emphasize the usefulness of fuzzy logic and explore different aspects of control systems and power systems. In the field of microgrids, a study [50] was conducted to examine the effectiveness of fuzzy control. The study concludes that a simple FLC with only one input can provide comparable results to a traditional PI (proportional-integral) controller, but it is easier to adjust.…”

Fuzzy-based control systems have demonstrated a remarkable ability to control nonlinear processes, a characteristic commonly observed in power systems, particularly in the context of power quality enhancement. Despite this, an updated and comprehensive literature review on the applications of fuzzy logic in the domain of power quality control has been lacking. To address this gap, this study critically examines published research on the effective and efficient use of fuzzy logic in resolving quality issues within power systems. Data sources included the Web of Science and academic journal databases, followed by an evaluation of target articles based on predefined criteria. The information was then classified into seven categories, including control system type, features of the fuzzy logic controller, fuzzy logic inference strategy, power quality issue, control device, implementation methodology (efficacy testing), and efficiency improvement. Our study revealed that fuzzy-based control systems have evolved from simple type-1 fuzzy controllers to advanced control systems (type-2 fuzzy and hybrid) capable of effectively addressing complex power quality issues. We believe that the insights gained from this study will be useful to both experienced and inexperienced researchers and industry engineers seeking to leverage fuzzy logic to enhance power quality control.

“…Energy management and the conversion of renewable energy generated (RES) into electricity and its storage, requires the use of electronic devices as power converter systems and must be ideal in configuration and size and meet the requirements for optimum operation of microgrid in terms of high efficiency, performance, reliability, stability, low cost, protection, and effective energy regulation [2], [3]. One of the most important electronic power converters, which is an inverter.…”

To ensure enhanced reliability and availability of electricity to consumers, grid-connected photovoltaic systems need to improve their power quality, this paper uses a three-phase five levels cascaded H-bridge inverter in grid-connected mode to improve the flexibility and efficiency of the photovoltaic system. Each photovoltaic (PV) array in the proposed system has a maximum power point tracker (MPPT) to extract the PV array maximum power point for a particular irradiance and temperature and reduce the mismatch that causes an imbalance in the power sent from the inverter to the main grid. The fuzzy logic controller is used to tune the proportional-integral (PI) controller to regulate the current and voltage of the grid-connected inverter by changing the gain of the PI controller (Kp, Ki) to obtain a fast response and improve the power quality of the system despite different load disturbances and inputs. The system was simulated in MATLAB/Simulink, and the results show the superiority of the proposed control unit, in which a pure and stable sine output voltage and current waveforms. Finally, the total harmonic distortion (THD) is improved to reach 3.81% based on the fuzzy PI controller, while 7.77% is based on the PI controller.
