Impacto del vehículo eléctrico sobre las redes de distribución

Es objeto del presente proyecto definir red inteligente (Smart Grid) como parte fundamental de un futuro sistema de generación, distribución y transporte de la energía, utilizando como medio principal de desplazamiento el Vehículo Eléctrico. El desarrollo del proyecto se lleva a cabo a través de un análisis exhaustivo del impacto de la introducción masiva del Vehículo Eléctrico en las redes de distribución. Para evaluar las simulaciones se han creado unos niveles de penetración de vehículos, así como el despliegue de dispositivos de recarga y hora óptima de conexión a la red para que la curva de demanda se suavice lo máximo posible y las infraestructuras eléctricas no sufran una sobrecarga provocando una caída del sistema eléctrico. Con un software específico, se ha obtenido un porcentaje de pérdidas y se han sacado unas conclusiones para los distintos casos de penetración del vehículo eléctrico. Asimismo, se ha analizado la implementación de un sistema que estudie los intercambios energéticos que se producen entre los diferentes sistemas del vehículo, y entre éste y su entorno para poder disminuir las pérdidas. ABSTRACT The objective of this project is to define Smart Grid as an essential part of a future generation system, distribution and transmission of energy, using Electric Vehicle as primary mean of moving. The development of this project was carried out through a comprehensive analysis of the impact of the massive introduction of electric vehicles in distribution networks. To evaluate the simulations, different indicators for vehicle´s penetration were created, as well as the deployment of charging devices and optimal time to get network connection in order to smooth the demand curve as much as possible and to avoid electrical infrastructure being overloaded and thus causing the electrical system to stop working. For each of the different cases of electric vehicles’ penetration a percentage of losses and conclusions were drawn using specific software. The implementation of a system that studies the exchanges of energy that occur between different vehicle systems and between itself and its environment to reduce losses was also analyzed.

Model-Driven Methodology for Rapid Deployment of Smart Spaces based on Resource-Oriented Architectures

Advances in electronics nowadays facilitate the design of smart spaces based on physical mash-ups of sensor and actuator devices. At the same time, software paradigms such as Internet of Things (IoT) and Web of Things (WoT) are motivating the creation of technology to support the development and deployment of web-enabled embedded sensor and actuator devices with two major objectives: (i) to integrate sensing and actuating functionalities into everyday objects, and (ii) to easily allow a diversity of devices to plug into the Internet. Currently, developers who are applying this Internet-oriented approach need to have solid understanding about specific platforms and web technologies. In order to alleviate this development process, this research proposes a Resource-Oriented and Ontology-Driven Development (ROOD) methodology based on the Model Driven Architecture (MDA). This methodology aims at enabling the development of smart spaces through a set of modeling tools and semantic technologies that support the definition of the smart space and the automatic generation of code at hardware level. ROOD feasibility is demonstrated by building an adaptive health monitoring service for a Smart Gym.

Design and modeling of the multi-agent robotic system: SMART

This article presents the design, kinematic model and communication architecture for the multi-agent robotic system called SMART. The philosophy behind this kind of system requires the communication architecture to contemplate the concurrence of the whole system. The proposed architecture combines different communication technologies (TCP/IP and Bluetooth) under one protocol designed for the cooperation among agents and other elements of the system such as IP-Cameras, image processing library, path planner, user Interface, control block and data block. The high level control is modeled by Work-Flow Petri nets and implemented in C++ and C♯♯. Experimental results show the performance of the designed architecture.

Ubiquitous green computing techniques for high demand applications in smart environments

Ubiquitous sensor network deployments, such as the ones found in Smart cities and Ambient intelligence applications, require constantly increasing high computational demands in order to process data and offer services to users. The nature of these applications imply the usage of data centers. Research has paid much attention to the energy consumption of the sensor nodes in WSNs infrastructures. However, supercomputing facilities are the ones presenting a higher economic and environmental impact due to their very high power consumption. The latter problem, however, has been disregarded in the field of smart environment services. This paper proposes an energy-minimization workload assignment technique, based on heterogeneity and application-awareness, that redistributes low-demand computational tasks from high-performance facilities to idle nodes with low and medium resources in the WSN infrastructure. These non-optimal allocation policies reduce the energy consumed by the whole infrastructure and the total execution time.

Towards a lightweight mobile semantic-based approach for enhancing interaction with smart objects

This work describes a semantic extension for a user-smart object interaction model based on the ECA paradigm (Event-Condition-Action). In this approach, smart objects publish their sensing (event) and action capabilities in the cloud and mobile devices are prepared to retrieve them and act as mediators to configure personalized behaviours for the objects. In this paper, the information handled by this interaction system has been shaped according several semantic models that, together with the integration of an embedded ontological and rule-based reasoner, are exploited in order to (i) automatically detect incompatible ECA rules configurations and to (ii) support complex ECA rules definitions and execution. This semantic extension may significantly improve the management of smart spaces populated with numerous smart objects from mobile personal devices, as it facilitates the configuration of coherent ECA rules.

A Development Methodology to Facilitate the Integration of Smart Spaces into the Web of Things

How to create or integrate large Smart Spaces (considered as mash-ups of sensors and actuators) into the paradigm of ?Web of Things? has been the motivation of many recent works. A cutting-edge approach deals with developing and deploying web-enabled embedded devices with two major objectives: 1) to integrate sensor and actuator technologies into everyday objects, and 2) to allow a diversity of devices to plug to Internet. Currently, developers who want to use this Internet-oriented approach need have solid understanding about sensorial platforms and semantic technologies. In this paper we propose a Resource-Oriented and Ontology-Driven Development (ROOD) methodology, based on Model Driven Architecture (MDA), to facilitate to any developer the development and deployment of Smart Spaces. Early evaluations of the ROOD methodology have been successfully accomplished through a partial deployment of a Smart Hotel.

Smart parking service based on wireless sensor networks

n this paper, we present the design and implementation of a prototype system of Smart Parking Services based on Wireless Sensor Networks (WSNs) that allows vehicle drivers to effectively find the free parking places. The proposed scheme consists of wireless sensor networks, embedded web-server, central web-server and mobile phone application. In the system, low-cost wireless sensors networks modules are deployed into each parking slot equipped with one sensor node. The state of the parking slot is detected by sensor node and is reported periodically to embedded web-server via the deployed wireless sensor networks. This information is sent to central web-server using Wi-Fi networks in real-time, and also the vehicle driver can find vacant parking lots using standard mobile devices.

Smart Spaces and Smart Objects interoperability Architecture (S3OiA)

The presented work aims to contribute towards the standardization and the interoperability off the Future Internet through an open and scalable architecture design. We present S³OiA as a syntactic/semantic Service-Oriented Architecture that allows the integration of any type of object or device, not mattering their nature, on the Internet of Things. Moreover, the architecture makes possible the use of underlying heterogeneous resources as a substrate for the automatic composition of complex applications through a semantic Triple Space paradigm. Created applications are dynamic and adaptive since they are able to evolve depending on the context where they are executed. The validation scenario of this architecture encompasses areas which are prone to involve human beings in order to promote personal autonomy, such as home-care automation environments and Ambient Assisted Living.

Validation tool for smart screening of language disorders in pediatrics care

Primary-care pediatricians could play a key role in early detection of development disorders as quick as they might have enough time and knowledge for suitable screenings at clinical routine. This research paper focuses on the development and validation of a knowledge-based web tool whose aim is to support a smart detection of developmental disorders in early childhood. Thus, the use of the system can trigger the necessary preventive and therapeutic actions from birth until the age of six. The platform was designed on the basis of an analysis of significant 21 cases of children with language disorders that supported the creation of a specific knowledge base, its ontology and a set of description logic relations. The resulting system is being validated in a scalable approach with a team of seven experts from the fields of neonathology, pediatrics, neurology and language therapy.

The resulting system was developed on the basis of an analysis and verification of 21 cases of children with language disorders.

Ensayos de laboratorio para la medida de la tasa de absorción específica (SAR) en dispositivos móviles

El proyecto trata del estudio de la tasa de absorción específica (SAR). En él se estudia la SAR que desprenden distintos dispositivos de comunicaciones inalámbricos. Se ha llevado a cabo en las instalaciones de la SETSI, en el laboratorio de radiofrecuencia situado en El Casar, Guadalajara, que pertenece al Ministerio de Industria Comercio y Turismo. La SAR es una relación entre la energía electromagnética acumulada en una masa de un material o tejido concreto. Por tanto, lo primero es definir la SAR, en la que se exponen sus parámetros. Además, se recogen los límites de exposición fijados por las normas internacionales IEC 62209-1 e IEC 62209-2 en relación a SAR. Posteriormente, acorde con las normas, se realiza una definición detallada de un banco de medidas de SAR, en donde se explica cada uno de los componentes del banco de manera detallada así como los sistemas que intervienen previamente a la realización de la medida, tipos de los sistemas para realizar las verificaciones pertinentes, y también las incertidumbres de ciertos parámetros. También se realiza un proceso completo de medida de SAR en el laboratorio de la SETSI, donde se realizan las comprobaciones necesarias para la realización de una serie de medidas sobre dispositivos de comunicaciones móviles. Éstas medidas se realizan primero sobre un teléfono móvil en las frecuencias de GSM, UMTS y WIFI, en las configuraciones estipuladas por la norma; “tocando” e “inclinada 15°” comparando los valores obtenidos con los límites marcados por las normas internacionales. Por último, en este apartado se realizan ciertas medidas con otras configuraciones que no están recogidas en la norma para intentar obtener los máximos valores de SAR posibles. Después se realiza una comparación entre dos dispositivos tipo “tablet”, para ello se realizan medidas en la banda de WIFI y se comentan los resultados obtenidos, relacionado con el diseño de cada uno de ellos. Posteriormente se realiza un presupuesto de un banco de SAR, donde se detallan todos los componentes que intervienen en la realización de las medidas de SAR, pero no se incluyen en él, los costes de mantenimiento o los costes relacionados con su uso. Por último se explican las conclusiones finales desprendidas de la realización de este proyecto de fin de carrera así como la bibliografía utilizada.

Medidas y extracción de parámetros de dispositivos y redes SMATV

En este Proyecto Fin de Carrera trata de dar a conocer de forma detallada el comportamiento real en frecuencia de una red de distribución SMATV y establecer un procedimiento que pueda permitir una predicción más o menos precisa de su funcionamiento. Se realizará una reflexión sobre los procedimientos de cálculo que se emplean en entornos profesionales para el diseño de estas redes y sus carencias. En concreto nos centraremos en el uso de conectores y kits de conexión que se utilizan frecuentemente en redes SMATV. A la hora de realizar un proyecto de una red de este tipo solo se tienen en cuenta las perdidas por inserción de los conectores, y en muchas ocasiones ni siquiera eso, se realiza una estimación al alza y con eso basta. Este proyecto pretende demostrar la relevancia de los conectores dentro de una red, y tratar de arrojar luz sobre los aspectos más importantes a tener en cuenta a la hora de elegir e instalar un conector. Abstract In this Thesis is to present in detail the actual behavior frequency SMATV distribution network and establish a procedure to allow more or less accurate prediction of its operation. There will be a reflection on the calculation procedures used in professional environments for the design of these networks and their shortcomings. In particular we will focus on the use of connectors and connection kits that are frequently used in SMATV networks. When a project of this type network only takes into account the insertion loss of the connectors, and often not even that, an estimate is made up and that's enough. This project aims to demonstrate the relevance of the connectors within a network, and try to shed light on the most important aspects to consider when choosing and installing a connector.
