Uso de supercondensadores para brindar soporte de frecuencia en una microrred aislada

Abstract: Este artículo presenta la implementación práctica de una técnica de control de frecuencia (inercia virtual) en un sistema de almacenamiento energético basado en el uso de supercondensadores (SAE-SC). La propuesta estuvo diseñada para brindar soporte de frecuencia a una microrred eléctrica aislada real que integra fuentes de generación renovable (solar fotovoltaica, 15 kWp), generación síncrona convencional (térmico diésel, 44 kVA) y sistemas de almacenamiento energético (SAE-SC, 30 kW). Tomando como caso base … Show more

“…Table 2 presents these results: In the case study, a dynamic analysis of the solar-wind-diesel system is proposed with support in energy storage systems operated in island mode, considering the disturbances of renewable energies, in which the two perspectives are mainly analyzed regarding the response of the system without RES penetration and with RES penetration. The mathematical modeling and the parameters of the virtual inertia control were developed based on the characteristics of the renewable generation equipment and systems of the Centro Científico, Tecnológico y de Investigación Balzay (CCTI-B) of the University of Cuenca [26,40]; they are presented in the following Figure 4. The laboratory mainly consists of a photovoltaic generation system (35 kW), a mini wind farm (15 kW), a diesel generator (40 kVA), storage systems with Valve-Regulated Lead-Acid (VRLA) Gel battery bank (15 kWh), and a programmable electrical load that allows for the creation of step scenarios every 5 kW.…”

“…The Model Predictive Control (MPC) techniques are shown to improve the capability of energy storage units in managing power fluctuation control. Likewise, the authors of [26] propose the use of supercapacitors to provide frequency support to an isolated microgrid considering the solar-diesel hybrid system and fast response energy storage systems, thus achieving a reduction of up to 30% in fluctuations of frequency.…”
