Abstract
La necesidad de adecuar en todo momento la
producción a la demanda energética de los hogares
hace necesario, para microrredes basadas en fuentes
de energías renovables (FER), el uso de sistemas de
almacenamiento energético, para así acumular los
excesos energéticos producidos por las energías
renovables y usarlos en momentos de déficit de
producción, debido a la naturaleza intermitente de
las FER. Por otra parte, como las microrredes
renovables hibridadas con hidrógeno están
compuestas por distintos elementos de producción y
almacenamiento de diferentes características y
dinámicas, es decir, tienen una naturaleza
multicomponente, es imprescindible la
implementación de sistemas de gestión energética
(SGE), con el propósito de hallar los mejores
servicios para cada elemento de la microrred, lo que
permitirá conseguir conjuntamente un correcto
funcionamiento de la misma. En ese sentido, la
propuesta de este artículo es implementar un SGE
basado en un controlador lógico borroso (CLB)
multivariable y multietapa que haga frente a un
problema multiobjetivo para mejorar el
comportamiento de los elementos de la microrred en
términos de tiempo de vida, eficiencia y costes de
operación. Para lograr dicho objetivo, se
considerará tanto el balance de potencia, el
rendimiento y la degradación de los elementos de la
microrred como los costes y beneficios de conexión
de la microrred con la red eléctrica principal. En
comparación con SGE tradicionales, como los
basados en modelos o técnicas heurísticas, el SGE
propuesto supone, de acuerdo a los resultados
obtenidos, un mayor rendimiento y un mayor
beneficio económico.
To adapt production to household energy demand at all times it is necessary, for microgrids based on renewable energy sources (RES), to use energy storage systems in order to accumulate excess energy produced by renewable energies and use them in times of production deficit, due to the intermittent nature of RES. On the other hand, as hydrogen hybridized renewable microgrids are composed of different production and storage elements with different characteristics and dynamics, i.e., they have a multicomponent nature, so it is essential to implement energy management systems (EMS), in order to find the best services for each element of the microgrid, which will jointly achieve a correct operation of the microgrid. In that sense, the proposal of this article is to implement an EMS based on a multivariable and multistage fuzzy logic controller (FLC) that faces a multi-objective problem to improve the behavior of the microgrid elements in terms of lifetime, efficiency and operation costs. To achieve that objective, both the power balance, performance and degradation of the microgrid elements and the costs and benefits of connecting the microgrid to the main power grid will be considered. Compared to traditional EMS, such as those based on models or heuristic techniques, the proposed EMS implies, according to the results obtained, a higher performance and a higher economic benefit.
