One of the great advantages of this system is the ease of installation. Similarly, systems composed of hydrokinetic turbines have been analyzed with promising results. This is an innovative technology as it does not need dikes to generate electricity. Īn interesting source of renewable power generation is hydrokinetic turbines (HKT). Therefore, different energy storage technologies have been considered to analyze the impact on the renewable hybrid system.

In addition, several works use various methods to reduce CO 2 emissions, for example, energy control systems to start the diesel generator depending on the state of renewable sources and batteries. Some studies use computational tools such as HOMER and Matlab to find an optimal model through objective functions. References explain the analysis of the performance and sizing optimization in renewable hybrid systems composed of photovoltaic (PV) and wind energy (WT). There are several computational methods to evaluate the behavior of renewable systems, depending on the environmental conditions of the study site. This study analyzes an off-grid hybrid system formed by PV-WT-HKT-DG to reduce the operation and fuel consumption of diesel generators. On the other hand, hydrokinetic energy (HKT) is currently a promising technology considering the economic advantage of its installation. The conclusions have shown that, when using more than one renewable source, the system energy efficiency is greater and the operation of the diesel generator (DG) is significantly reduced. Several studies related to the mentioned technologies have been analyzed in cases of isolated communities powered by off-grid hybrid systems that use both technologies simultaneously, backed by a diesel generator. Energy sources such as solar photovoltaic panels (PV) and wind turbines (WT) have been frequently used, due to their constant cost reductions and growing industrial and residential applications. Therefore, future generations must consume energy through clean technologies without compromising the environment. Sustainable development considerations are essential for a society in constant economic growth. Palabras clave: Microrred, almacenamiento de energía, energía renovable. Finalmente, los análisis de sensibilidad han demostrado que: al incrementarse la demanda, el consumo de diesel no incrementa significativamente al usar baterías de flujo de vanadio redox y las horas de operacion del generador diesel disminuyen considerablemente en todos los sistemas. Por otro lado, al usar las baterías de ion litio bajo el control ciclo de carga, la penetración del generador diesel se ha reducido considerablemente sin afectar al costo del sistema. Los resultados muestran que es posible reducir el consumo de diesel progresivamente, sin embargo el costo de la energía aumenta.

El software HOMER se ha utilizado para calcular el tamaño óptimo de los sistemas a través de indicadores técnico-económicos. Además, se han considerado diferentes tecnologías de almacenamiento de energía (plomo ácido, iones de litio, flujo redox de vanadio, almacenamiento de bomba y supercondensador). Se han propuesto tres estrategias de despacho de energía para verificar el impacto en el consumo de diesel y las horas de operación del generador. Por lo tanto, este documento presenta una estrategia para reducir el consumo de diesel en un sistema fuera de la red formado por fuentes renovables (PV-HKT-WT-DG). Keywords: Microgrid, energy storage, renewable energy.Īunque el cambio climático es una realidad, muchas comunidades fuera de la red continúan utilizando generadores diesel para suministrar electricidad. Finally, sensitivity analyzes have shown that when demand increases, diesel consumption does not increase significantly by using redox vanadium flow batteries, whereas the diesel generator operating hours decrease significantly in all systems. On the other hand, when using lithium-ion batteries under charge cycle control, the penetration of the diesel generator has been greatly reduced without affecting the cost of the system. The results show that it is possible to reduce diesel consumption progressively however, the cost of energy increases. The HOMER software has been used to calculate the optimal size of the systems through technical-economic indicators. In addition, different energy storage technologies (acid lead, lithium-ion, vanadium redox flow, pump storage and supercapacitor) have been considered. Three energy dispatch strategies have been proposed to verify the impact on diesel consumption and generator operating hours. This document presents a strategy to reduce diesel consumption in an out-of-grid system formed by renewable sources (PV-HKT-WT-DG). Although climate change is a reality, many off-grid communities continue to use diesel generators for electricity supply.
