Competencias emocionales y rendimiento académico en los estudiantes de Educación Primaria

El papel que juegan las emociones en el contexto educativo es fundamental, por lo que es necesario profundizar en la influencia de la inteligencia emocional a la hora de determinar el rendimiento académico de los estudiantes. El objetivo del presente estudio es analizar la relación de la inteligencia emocional sobre el rendimiento académico en una muestra de estudiantes de Educación Primaria. En concreto, tomaron parte en el estudio un total de 146 estudiantes del tercer ciclo de la etapa, con edades entre los 10 y 12 años, de tres centros públicos de Educación Primaria a los que se les aplicó el cuestionario TMMS-24. Los resultados encontrados muestran una asociación entre los niveles de inteligencia emocional y el rendimiento académico de los estudiantes, existiendo diferencias significativas entre hombres y mujeres a la hora de percibir las emociones. Un trabajo continuado por parte de los docentes de la capacidad de expresión, comprensión y regulación emocional puede mejorar el rendimiento académico del alumnado

A virtual power plant model for time-driven power flow calculations

This paper presents the implementation of a custom-made virtual power plant model in OpenDSS. The goal is to develop a model adequate for time-driven power flow calculations in distribution systems. The virtual power plant is modeled as the aggregation of renewable generation and energy storage connected to the distribution system through an inverter. The implemented operation mode allows the virtual power plant to act as a single dispatchable generation unit. The case studies presented in the paper demonstrate that the model behaves according to the specified control algorithm and show how it can be incorporated into the solution scheme of a general parallel genetic algorithm in order to obtain the optimal day-ahead dispatch. Simulation results exhibit a clear benefit from the deployment of a virtual power plant when compared to distributed generation based only on renewable intermittent generation.Peer ReviewedPostprint (published version

Reliability analysis of distribution systems with photovoltaic generation using a power flow simulator and a parallel Monte Carlo approach

This paper presents a Monte Carlo approach for reliability assessment of distribution systems with distributed generation using parallel computing. The calculations are carried out with a royalty-free power flow simulator, OpenDSS (Open Distribution System Simulator). The procedure has been implemented in an environment in which OpenDSS is driven from MATLAB. The test system is an overhead distribution system represented by means of a three-phase model that includes protective devices. The paper details the implemented procedure, which can be applied to systems with or without distributed generation, includes an illustrative case study and summarizes the results derived from the analysis of the test system during one year. The goal is to evaluate the test system performance considering different scenarios with different level of system automation and reconfiguration, and assess the impact that distributed photovoltaic generation can have on that performance. Several reliability indices, including those related to the impact of distributed generation, are obtained for every scenario.Postprint (published version

A Solid State Transformer model for power flow calculations

This paper presents the implementation of a Solid State Transformer (SST) model in OpenDSS. The goal is to develop a SST model that could be useful for assessing the impact that the replacement of the conventional iron-and-copper transformer with the SST can have on the distribution system performance. Test distribution systems of different characteristics and size have been simulated during different time periods. The simulations have been carried out assuming voltage-dependent loads and considering that power flow through either the HV/MV substation transformer or any of the MV/LV distribution transformers can be bidirectional. Simulation results prove that a positive impact should be expected on voltages at both MV and LV levels, but the efficiency of current SST designs should be improved.Postprint (author's final draft

Evaluating the more suitable ISM frequency band for iot-based smart grids: a quantitative study of 915 MHz vs. 2400 MHz

IoT has begun to be employed pervasively in industrial environments and critical infrastructures thanks to its positive impact on performance and efficiency. Among these environments, the Smart Grid (SG) excels as the perfect host for this technology, mainly due to its potential to become the motor of the rest of electrically-dependent infrastructures. To make this SG-oriented IoT cost-effective, most deployments employ unlicensed ISM bands, specifically the 2400 MHz one, due to its extended communication bandwidth in comparison with lower bands. This band has been extensively used for years by Wireless Sensor Networks (WSN) and Mobile Ad-hoc Networks (MANET), from which the IoT technologically inherits. However, this work questions and evaluates the suitability of such a "default" communication band in SG environments, compared with the 915 MHz ISM band. A comprehensive quantitative comparison of these bands has been accomplished in terms of: power consumption, average network delay, and packet reception rate. To allow such a study, a dual-band propagation model specifically designed for the SG has been derived, tested, and incorporated into the well-known TOSSIM simulator. Simulation results reveal that only in the absence of other 2400 MHz interfering devices (such as WiFi or Bluetooth) or in small networks, is the 2400 MHz band the best option. In any other case, SG-oriented IoT quantitatively perform better if operating in the 915 MHz band.This research was supported by the MINECO/FEDER project grants TEC2013-47016-C2-2-R (COINS) and TEC2016-76465-C2-1-R (AIM).

Intervención psicológica en militares españoles desplegados en operaciones internacionales

Artículo en inglésBackground: Spain was one of the fi rst countries to recognize the importance of psychological aspects in the planning and development of international military operations, and also to include military psychologists in contingents deployed abroad. Method: This paper describes the psychological intervention model used by Spanish military psychologists involved in military operations abroad. Results: This model is comprised of a systematic set of interventions and actions carried out in the different phases of any military operation (concentration, deployment and postmission). It also contemplates the intervention not only in personnel who integrate the military contingents, but also with their families and, at certain times of the mission, with the local population of the area in which the operation is carried out. Conclusions: The model presented has a preventive orientation, based on the selection and psychological preparation of contingents before deployment, and supplemented by support in the area of operations for personnel who need it, and the psychological care of their families in Spain. Whereas this model has been effective so far, in this work, we present a series of measures aimed at improving the psychological well-being of our troops deployed outside our country.Antecedentes: España ha sido pionera en reconocer la importancia de los aspectos psicológicos en la planifi cación y desarrollo de las operaciones militares internacionales, y en incluir a psicólogos en los contingentes desplegados en ellas. Método: este trabajo describe el modelo de intervención psicológica utilizado por los psicólogos militares españoles que participan en misiones y operaciones en el exterior. Resultado: dicho modelo está conformado por un conjunto sistematizado de intervenciones y actuaciones que se llevan a cabo en las distintas fases que componen toda operación militar (concentración, despliegue y postmisión). Igualmente contempla la intervención tanto en el personal que integra los contingentes militares, como en sus familias y, en determinados momentos de la misión, en la población local de la zona en que se desarrolla. Conclusiones: el modelo presentado posee una orientación claramente preventiva, basada en la selección y preparación psicológica del contingente antes del despliegue, y complementada con la asistencia en zona de operaciones al personal que lo requiera y la atención a sus familias en territorio nacional. Pese a la efi cacia de dicho modelo, se analizan sus limitaciones y se exponen algunas medidas para mejorar el bienestar psicológico de nuestras tropas desplegadas en el exterior.Siete página

Nowcasting solar radiation using cloud satellite and high resolution numerical model outputs

Póster presentado en: EMS Annual Meeting: European Conference for Applied Meteorology and Climatology celebrado del 4–8 de septiembre de 2017 en Dublin, IrelandAEMET (the Spanish Meteorological Agency) is currently developing a project for the Spanish transmission system operator, Red Eléctrica de España, to improve hourly Global Horizontal Irradiance (GHI) and direct Normal Irradiance (DNI) forecasts in Spanish solar power plants. Nowcasting is a technique for very short-range forecasting (normally within 6h ahead) covering only a very specific geographic region. There is a need of using nowcasting models to forecast the availability of solar radiation in order to low electricity generating costs. We present the current status of a nowcasting tool developed by AEMET that provides every 15 min the hourly solar radiation accumulated fluxes for the coming 4 hours. The meteorological data used for this model are: satellite cloud type observations and forecasts based on high resolution winds (EUMETSAT SAFNWC/MSG software package outputs), radiation from high resolution numerical weather prediction model (HARMONIE/AROME radiation outputs) or a combination of both sources of information depending on different forecast time horizons. The accuracy of the tool has been analyzed comparing the GHI and DNI forecasts with the ground solar radiation measurements from seven stations of AEMET network. The verification results in terms of RMSE are similar to those found in the bibliography, with the advantage that the satellite component of the tool does not require the use of a model to convert satellite imagery to average insolation on the groun
