Forecasting Recharging Demand to Integrate Electric Vehicle Fleets in Smart Grids

Electric vehicle fleets and smart grids are two growing technologies. These technologies provided new possibilities to reduce pollution and increase energy efficiency. In this sense, electric vehicles are used as mobile loads in the power grid. A distributed charging prioritization methodology is proposed in this paper. The solution is based on the concept of virtual power plants and the usage of evolutionary computation algorithms. Additionally, the comparison of several evolutionary algorithms, genetic algorithm, genetic algorithm with evolution control, particle swarm optimization, and hybrid solution are shown in order to evaluate the proposed architecture. The proposed solution is presented to prevent the overload of the power grid

Teaching Innovation in Order to Integrate Self-Learning and Self-Evaluation in the Webct Platform

El concepto de docencia universitaria tradicional se ha visto modificado por los principios definidos en el Espacio Europeo de Educación Superior. Un cambio metodológico que motiva el concepto de autoevaluación y promueve todas aquellas actividades académicas que faciliten el autoaprendizaje. En este escenario, es fundamental que los estudiantes adquieran nuevos hábitos autoformativos. Nuestro trabajo presenta un método de enseñanza-aprendizaje para que ésta pase a ser más activa y participativa. Este proyecto permite al alumno disponer de un conjunto de recursos, que favorecen la autoevaluación y autoformación, a la vez que facilita su trabajo personal y en equipo.In the European Higher Education Area (EHEA) the traditional teaching university concept has changed.

Monitoring and Fault Location Sensor Network for Underground Distribution Lines

One of the fundamental tasks of electric distribution utilities is guaranteeing a continuous supply of electricity to their customers. The primary distribution network is a critical part of these facilities because a fault in it could affect thousands of customers. However, the complexity of this network has been increased with the irruption of distributed generation, typical in a Smart Grid and which has significantly complicated some of the analyses, making it impossible to apply traditional techniques. This problem is intensified in underground lines where access is limited. As a possible solution, this paper proposes to make a deployment of a distributed sensor network along the power lines. This network proposes taking advantage of its distributed character to support new approaches of these analyses. In this sense, this paper describes the aquiculture of the proposed network (adapted to the power grid) based on nodes that use power line communication and energy harvesting techniques. In this sense, it also describes the implementation of a real prototype that has been used in some experiments to validate this technological adaptation. Additionally, beyond a simple use for monitoring, this paper also proposes the use of this approach to solve two typical distribution system operator problems, such as: fault location and failure forecasting in power cables.Ministerio de Economía y Competitividad, Government of Spain project Sistema Inteligente Inalámbrico para Análisis y Monitorización de Líneas de Tensión Subterráneas en Smart Grids (SIIAM) TEC2013-40767-RMinisterio de Educación, Cultura y Deporte, Government of Spain, for the funding of the scholarship Formación de Profesorado Universitario 2016 (FPU 2016

Increasing the Efficiency of Rule-Based Expert Systems Applied on Heterogeneous Data Sources

Nowadays, the proliferation of heterogeneous data sources provided by different research and innovation projects and initiatives is proliferating more and more and presents huge opportunities. These developments create an increase in the number of different data sources, which could be involved in the process of decisionmaking for a specific purpose, but this huge heterogeneity makes this task difficult. Traditionally, the expert systems try to integrate all information into a main database, but, sometimes, this information is not easily available, or its integration with other databases is very problematic. In this case, it is essential to establish procedures that make a metadata distributed integration for them. This process provides a “mapping” of available information, but it is only at logic level. Thus, on a physical level, the data is still distributed into several resources. In this sense, this chapter proposes a distributed rule engine extension (DREE) based on edge computing that makes an integration of metadata provided by different heterogeneous data sources, applying then a mathematical decomposition over the antecedent of rules. The use of the proposed rule engine increases the efficiency and the capability of rule-based expert systems, providing the possibility of applying these rules over distributed and heterogeneous data sources, increasing the size of data sets that could be involved in the decision-making process

A Precise Electrical Disturbance Generator for Neural Network Training with Real Level Output

Power Quality is defined as the study of the quality of electric power lines. The detection and classification of the different disturbances which cause power quality problems is a difficult task which requires a high level of engineering expertise. Thus, neural networks are usually a good choice for the detection and classification of these disturbances. This paper describes a powerful tool, developed by the Institute for Natural Resources and Agrobiology at the Scientific Research Council (CSIC) and the Electronic Technology Department at the University of Seville, which generates electrical patterns of disturbances for the training of neural networks for PQ tasks. This system has been expanded to other applications (as comparative test between PQ meters, or test of effects of power-line disturbances on equipment) through the addition of a specifically developed high fidelity power amplifier, which allows the generation of disturbed signals at real levels.Ministerio de Ciencia y Tecnología DPI2006-15467-C02-0

Science education in the Andalusia’s official curriculum for Primary Education: a critical analysis

Se presentan los resultados de un análisis crítico, de corte interpretativo, sobre la educación científica que se promueve desde el curriculum oficial de Primaria para Andalucía. Para ello, se aplicó un protocolo de análisis, ya validado por los autores en estudios anteriores, que integra una relación de estándares o posicionamientos predominantes en la Didáctica de las Ciencias actualmente. Como estrategia de fiabilidad, el análisis se hizo combinando procesos inter- e intra-jueces. Los resultados revelan que la educación científica sugerida oficialmente para Andalucía no sintoniza, en cierta medida, con las actuales tendencias en Didáctica de las Ciencias. A la vista de las carencias detectadas, se hacen algunas recomendaciones que mejorarían la propuesta oficial, al respecto.Science education promoted by Andalusia’s official curriculum for Primary Education is analyzed by means of a critical and interpretative analysis.
