Gestión óptima de almacenamientos de tipo estacional en sistemas integrados

La actual transición energética plantea, como desafío, desarrollar nuevas metodologías de análisis que promuevan la gestión racional y eficiente de los recursos energéticos y el desuso de combustibles altamente contaminantes. Una de las políticas más significativas en el sector eléctrico es promover el despliegue de energías renovables como plantas de energía eólica y solar. Sin embargo, a pesar del crecimiento y acogida que ha tenido este tipo de generación en los últimos años, se debe considerar que algunas características técnicas de este tipo de recursos, como la variabilidad a corto y mediano plazo, la temporalidad en la que se tiene disponible el recurso, y la incertidumbre en su disponibilidad, hacen necesario el uso de generación de otras fuentes de energía con tecnologías que permitan compensar dichas características y así mantener un suministro de energía confiable y seguro. En este sentido, las plantas de gas de ciclo combinado son una alternativa conveniente y atractiva, ya que tienen varias ventajas sobre otras centrales térmicas en cuanto a eficiencia, costos de inversión y tiempo de construcción. Además, las emisiones producidas por la quema de gas natural son menos nocivas para el medio ambiente al ser comparadas con otras plantas de generación de energía eléctrica que hacen uso de combustibles fósiles. No obstante, la alta penetración de este tipo de plantas impacta en la operación de la red de gas natural, ya que un fuerte incremento en el consumo de gas (como el asociado al consumo de las plantas a gas), implica grandes retos operativos y de planeamiento en términos de seguridad y suficiencia del sistema de gas natural.The current energy transition propose as a challenge, developing new analysis methodologies that promote the rational and efficient management of energy resources and the disuse of highly polluting fuels. One of the most significant policies in the electric sector is deployment of renewable energies such as wind and solar power plants. However, despite the growth and reception that this type of generation has had in recent years, it should be considered that some technical characteristics of this type of resource, such as short- and medium-term variability, the temporality in which it is availability of the resource and the uncertainty in its availability, make it necessary to use other energy sources with technologies that allow these characteristics to be compensated and thus maintain a reliable and secure energy supply. In this sense, combined cycle gas plants are a convenient and attractive alternative, since they have several advantages over other thermal power plants in terms of efficiency, investment costs and construction time. In addition, the emissions produced by burning natural gas are less harmful to the environment when compared to other electric power generation plants that use fossil fuels. However, the high penetration of this type of plant has an impact on the operation of the natural gas network, since a strong increase in gas consumption (such as that associated with the consumption of gas-fired plants), implies great operational and planning challenges in terms of safety and sufficiency of the natural gas system.DoctoradoDoctor(a) en IngenieríaTabla de contenido Agradecimientos.............................................................................................................................. 5 Resumen.......................................................................................................................................... 6 Tabla de contenido .............................................................................................................................. 8 Índice de Figuras............................................................................................................................... 10 Índice de Tablas ................................................................................................................................ 11 Estructura del documento.................................................................................................................. 12 1 Introducción .............................................................................................................................. 14 1.1.

Análisis del efecto de los embalses de sistemas hidrotérmicos en el costo de la energía y en las reservas usando AMPL

El presente artículo describe un modelo de programación lineal usando el lenguaje de modelamiento denominado AMPL y el solver CPLEX como herramienta de modelamiento matemático para solucionar un problema de despacho hidrotérmico de mediano plazo, que no considera la red de transmisión y considera costo de combustibles constantes. Se utiliza un sistema de prueba con dos plantas térmicas y tres hidráulicas que entran en operación en diferentes períodos de tiempo. Para las afluencias de las plantas hidráulicas se usan diez series hidrológicas, todas con la misma probabilidad de ocurrencia. Se implementan tres casos de análisis: filo de agua, embalse con meta de volumen al final del último periodo y embalse sin meta de volumen

High-resolution mass spectrometry identification of dye compounds and their degradation products in American cochineal from a historic shipping cargo

Cochineal dyes constitute paradigmatic organic compounds that guide in the elucidation of historic cultural and economical exchanges. This study combines liquid chromatography and high-resolution tandem mass spectrometry to assess the degradation products of the organic dyes of American cochineal collected from the cargo of a 16th century sunken wreck. The identification of biological materials of historical and archeological origin is often challenging due to molecular degradation. In this scenario, the mapping of the chemical routes underlying the fate of the organic and biochemical compounds employed as taxonomic biomarkers becomes of crucial importance. This work shows that, under harsh environmental conditions, the original carminic and (flavo)kermesic acid structures of cochineal dyes are prone to chemical transformation, typically losing the carboxylic acid and glucoside groups. The anthraquinone core is preserved in the majority of degradation products identified in this study, with eventual side chains reminiscent of a partial degradation of the glucoside moiety. The comparison of these observations with the analysis of modern cochineal samples allows us to lay out an updated chart of dye compounds and degradation products which should constitute a seminal benchmark for future biomolecular analysis of historic and archeological dye materials.Proyecto Arqueomemes (PY-FR-18:2001) Junta de Andalucía

The Mice at play in the CALIFA survey: A case study of a gas-rich major merger between first passage and coalescence

We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (>10^11Msol) gas-rich spirals NGC4676A and B, observed between first passage and final coalescence. The spectra provide stellar and gas kinematics, ionised gas properties and stellar population diagnostics, over the full optical extent of both galaxies. The Mice provide a perfect case study highlighting the importance of IFS data for improving our understanding of local galaxies. The impact of first passage on the kinematics of the stars and gas has been significant, with strong bars likely induced in both galaxies. The barred spiral NGC4676B exhibits a strong twist in both its stellar and ionised gas disk. On the other hand, the impact of the merger on the stellar populations has been minimal thus far: star formation induced by the recent close passage has not contributed significantly to the global star formation rate or stellar mass of the galaxies. Both galaxies show bicones of high ionisation gas extending along their minor axes. In NGC4676A the high gas velocity dispersion and Seyfert-like line ratios at large scaleheight indicate a powerful outflow. Fast shocks extend to ~6.6kpc above the disk plane. The measured ram pressure and mass outflow rate (~8-20Msol/yr) are similar to superwinds from local ULIRGs, although NGC4676A has only a moderate infrared luminosity of 3x10^10Lsol. Energy beyond that provided by the mechanical energy of the starburst appears to be required to drive the outflow. We compare the observations to mock kinematic and stellar population maps from a merger simulation. The models show little enhancement in star formation during and following first passage, in agreement with the observations. We highlight areas where IFS data could help further constrain the models.Comment: 23 pages, 13 figures, accepted to A&A.

Intermediate Molecular Phenotypes to Identify Genetic Markers of Anthracycline-Induced Cardiotoxicity Risk.

Cardiotoxicity due to anthracyclines (CDA) affects cancer patients, but we cannot predict who may suffer from this complication. CDA is a complex trait with a polygenic component that is mainly unidentified. We propose that levels of intermediate molecular phenotypes (IMPs) in the myocardium associated with histopathological damage could explain CDA susceptibility, so variants of genes encoding these IMPs could identify patients susceptible to this complication. Thus, a genetically heterogeneous cohort of mice (n = 165) generated by backcrossing were treated with doxorubicin and docetaxel. We quantified heart fibrosis using an Ariol slide scanner and intramyocardial levels of IMPs using multiplex bead arrays and QPCR. We identified quantitative trait loci linked to IMPs (ipQTLs) and cdaQTLs via linkage analysis. In three cancer patient cohorts, CDA was quantified using echocardiography or Cardiac Magnetic Resonance. CDA behaves as a complex trait in the mouse cohort. IMP levels in the myocardium were associated with CDA. ipQTLs integrated into genetic models with cdaQTLs account for more CDA phenotypic variation than that explained by cda-QTLs alone. Allelic forms of genes encoding IMPs associated with CDA in mice, including AKT1, MAPK14, MAPK8, STAT3, CAS3, and TP53, are genetic determinants of CDA in patients. Two genetic risk scores for pediatric patients (n = 71) and women with breast cancer (n = 420) were generated using machine-learning Least Absolute Shrinkage and Selection Operator (LASSO) regression. Thus, IMPs associated with heart damage identify genetic markers of CDA risk, thereby allowing more personalized patient management.J.P.L.’s lab is sponsored by Grant PID2020-118527RB-I00 funded by MCIN/AEI/10.13039/ 501100011039; Grant PDC2021-121735-I00 funded by MCIN/AEI/10.13039/501100011039 and by the “European Union Next Generation EU/PRTR”, the Regional Government of Castile and León (CSI144P20).
