Uno de los elementos más importantes de una red eléctrica es su sistema de distribución y transporte. Sin embargo, este sistema puede verse afectado por agentes externos o por el propio deterioro de sus elementos. Estos eventos indeseables suelen denominarse "faltas" y se traducen habitualmente en una interrupción del suministro eléctrico. En...

La desagregación no intrusiva de la demanda (o Non-Intrusive Load Monitoring, NILM) es una técnica computacional para la estimación del consumo individual de diversos dispositivos utilizando la lectura agregada de un solo medidor de energía (Smart Meter, SM). Este concepto ha tomado relevancia en los últimos años en el ámbito de las Smart...

En este documento se describen las diferentes líneas de investigación en las que actualmente trabaja el grupo TIC 150: Tecnología Electrónica e Informática Industrial del Departamento de Tecnología Electrónica (DTE) de la Universidad de Sevilla. Este grupo cuenta con una dilatada experiencia en proyectos de investigación, tanto de convocatorias...

This paper proposes an innovative and comprehensive method using transformer measured inrush current during the first breaker re-close to add usefull information as fault location problem input. It is divided into the main following sections: Introduction, Magnetizing Inrush Current- A Brief Analysis, Voltage Phase Estimation Method and...

Industrial distributed control continues the move toward networks at all levels. At lower levels, control networks provide flexibility, reliability, and low cost, although perhaps the simplest but most important advantage is the reduced volume of wiring. Powered fieldbuses offer particular notable benefits in system wiring simplification....

In this paper, an intelligent data analysis method for modeling and optimizing energy efficiency in smart buildings through Data Analytics (DA) is proposed. The objective of this proposal is to provide a Decision Support System (DSS) able to support experts in quantifying and optimizing energy efficiency in smart buildings, as well as reveal...

In a highly competitive and liberalized energy market, where the retail of electricity is open to many potential companies, it is essential to have tools that help make decisions and guide the design of marketing strategies. In this sense, it is essential for retailers to know the behavior of their customers to correctly define their commercial...

The process of digitalization has become a must in recent years. This digitalization affects not only to data management and communication, but also to most of the processes of the industry. One of the paradigms that have recently gained most attention is the creation of digital twins, i.e., accurate models of processes or elements that can be...

Nowadays, sound classification applications are becoming more common in the Wireless Acoustic Sensor Networks (WASN) scope. However, these architectures require special considerations, like looking for abalance between transmitted data and local processing.This article proposes an audio processing and classification scheme, focusing on WASN...

The increasing competition in the electric sector is challenging retail companies as they must assign its commercial efforts to attract the most profitable customers. Those are whose energy demand best fit certain target profiles, which usually depend on generation or cost policies. But, even when the demand profile is available, it is in an...

Las flotas de vehículos eléctricos y las Smart Grids son dos tecnologías emergentes muy prometedoras que han provisto nuevas formas de reducir la polución e incrementar la eficiencia energética. Naturalmente, estos elementos aumentan la complejidad de gestión del sistema eléctrico puesto que dichos vehículos pueden ser considerados como cargas...

Nowadays, the reliability and robustness levels required for production systems are growing. These demands make philosophies, such as predictive maintenance essential in modern industry, among which the energy sector stands out. In this sense, this paper proposes an on-line monitoring system based on data mining models, which provides a useful...

The arrival of new technologies related to smart grids and the resulting ecosystem of applications andmanagement systems pose many new problems. The databases of the traditional grid and the variousinitiatives related to new technologies have given rise to many different management systems with several formats and different architectures. A...

Much has been written about the rapidly emerging, the disruptive impact being detected on every aspect of how machines and their operational technology communicate with one another, with the underlying information technology platforms. Within the smart city exists an infrastructure of interconnected objects, people, systems, and...

Traditionally,Wireless SensorNetworks (WSNs) are used for monitoring an extensive area. In these networks, a centralized server is usually used to collect and store the sensor information.However, new distributed protocols allow connections directly to theWSN nodes without the need of a centralized server.Moreover, these systems are able to...

This paper addresses the problem of reducing the number of values required to characterize an electricity demand profile, which is usually known as its dimensionality. This reduction may have a significant impact on the computational efforts and storage capacities required to analyze and process high volumes of electricity load curves. Also,...

La predicción de generación y consumo eléctrico a corto plazo supone una herramienta de enorme interés dentro del sistema eléctrico, donde la presencia de fuentes de generación renovable y distribuida está en constante crecimiento. Específicamente, este tipo de predicción es esencial para la gestión energética en edificios, industrias y...

The integration of distributed energy resources in the power grid supposes a great challenge, considering the expected growing in the electric mobility and the renewable generation. Therefore, to support the successful deployment of these resources, energy management according to the expected behaviors of the elements of power grids is...

Los incendios plantean un grave problema no solo para los montes y bosques sino también para fauna que vive en ella. En este sentido, una política de detección temprana resulta esencial para controlar y sofocar rápidamente el incendio. Como solución para la detección temprana se plantea el uso de técnicas y algoritmos de tratamiento de imágenes...

La pandemia de COVID-19 ha causado problemas en todo el mundo. Para controlar la propagación del virus, algunos gobiernos han impuesto restricciones a la movilidad de sus ciudadanos. El efecto de estas acciones no solo se ha visto reflejado en datos epidemiológicos, sino también en el comportamiento de la población y, por lo tanto, en los...

The Non-Technical Losses (NTLs) represent the non-billed energy due to faults or illegal manipulations in customer facilities. The objective of the Midas project is the detection of NTL through the application of computational intelligence over the information stored in utility company databases. This project has several research lines. Some...
