This doctoral study discusses how to control fluctuating renewable energy sources at converter, unit, and system layers to deliver smoothed power output to the grid. This is particularly relevant to renewable power generation since the output power of many kinds of renewable energy sources have huge fluctuations (e.g. solar, wind and wave) that needs to be properly treated for grid integration. In this research, the energy quality is developed to describe the friendliness and compatibility of power flows/waveforms to the grid, by contrast with the well-known concept of power quality which is u

Abstract:
Thesis (D. Tech. (Electrical Engineering)) -- Central University of Technology, Free State, 2014<br>For a sustainable and clean electricity production in isolated rural areas, renewable energies appear to be the most suitable and usable supply options. Apart from all being renewable and sustainable, each of the renewable energy sources has its specific characteristics and advantages that make it well suited for specific applications and locations. Solar photovoltaic and wind turbines are well established and are currently the mostly used renewable energy sources for electricity generation in

Abstract:
El sector eléctrico de muchos países pasó por un proceso de reestructuración que tuvo su inicio en las décadas de los 80 y 90, cuyo objetivo era reorganizar el funcionamiento del sector eléctrico, mejorando su eficiencia y proporcionando así beneficios a largo plazo a los consumidores, como la reducción del precio de la electricidad. En España, este proceso se inicia en la práctica con la aprobación de la Ley 54 del Sector Eléctrico en 1997, que establecía las líneas generales de la reestructuración de las actividades del sector y además marcaba como objetivo el 12% del consumo de e

Abstract:
Pavements are one of the most important components of modern civil infrastructure systems. Being constantly exposed to weather conditions, pavements may be subject to heating and cooling cycles, which vary as a function of the location and are proven to reduce the lifespan and reliability of our transport infrastructure. The most extreme effects of weather are generally seen in the form of overheating of the paving materials or freezing of the pavement surface. In this Thesis, natural convection of air is considered as a means to harvest heat from pavements during hot periods and to provide he

Abstract:
Sustainable cities is an area that has grown in size over the last couple of years. The SESAC (Sustainable Energy Systems in Advanced Cities) is a EU-project looking at the potential to increase the share of Renewable Energy Sources (RES) and promote energy efficiency measures in different EU cities. This master thesis is a part of that project. Specifically, the thesis examines the cities of Grenoble, Delft and Växjö and looks at what measures regarding RES and energy efficiency have been taken historically, both under the SESAC project and otherwise, and assesses the possibility of further m

El núcleo de la tesis consta de tres capítulos en los que se explora la naturaleza de los flujos de conocimiento que influyen en la innovación en energías renovables. En los tres capítulos se utiliza información de patentes europeas a nivel regional para poder capturar el concepto de innovación. En el segundo capítulo explora la naturaleza de la base del conocimiento subyacente en las energías renovables. Se plantea que esta tecnología tiene un mayor contenido de conocimiento científico y abstracto que el resto de campos tecnológicos en general. Esta característica haría que, por un lado, el f

Les technologies de l'information et de la communication sont devenues, au cours des dernières années, un pôle majeur de consommation énergétique avec les conséquences environnementales associées. Dans le même temps, l'émergence du Cloud computing et des grandes plateformes en ligne a causé une augmentation en taille et en nombre des centres de données. Pour réduire leur impact écologique, alimenter ces centres avec des sources d'énergies renouvelables (EnR) apparaît comme une piste de solution. Cependant, certaines EnR telles que les énergies solaires et éoliennes sont liées aux conditions mé

Les énergies renouvelables variables prennent une part croissante de la production raccordée aux réseaux électriques. Par conséquent, elles doivent s’intégrer aux mécanismes de services système qui assurent l’équilibre entre production et con-sommation de puissance sur les réseaux. Toutefois la forte incertitude de la production variable est un obstacle à la fourniture de ces services qui requièrent une fiabilité élevée. L’agrégation de centrales renouvelables dispersées et contrôlées par une centrale virtuelle permet de diminuer cette incertitude en profitant du foisonnement entre les central

Includes bibliographical references.<br>With the drive for cleaner energy, Independent power producers (IPP’s) have to find suitable potential land sites that meet their renewable project needs and that prove to be technically feasible to integrate into the nearest distribution electrical infrastructure. Project feasibility for utility grid connection can in certain instances be directed to a specific area due to resource availability and existing electrical plant capability. This invariability leads to multiple establishments of renewable energy plants in the same geographic location. Distrib
