Prosumers in the regulatory framework of two EU members: Italy and Spain

This paper focuses on a typical customer with a PV plant and a battery storage by the perspective of two EU members: Italy and Spain. The authors calculate the electricity bill of the considered customer in accordance with the respective legislative and regulatory frameworks. This calculation is a preparatory and preliminary activity for finding relevant differences, if any, that should not exist between EU members. Given the 15-min load profile of a 3kW–3700kWh/yr domestic user, numerical experiments return that the ratio, between the electricity bills in Italy and Spain, relevantly changes with respect the adoption of local generator and local storage.

Seguridad Energética y Protección de Infraestructuras Críticas

In recent years, concerns on energy supply security have raised up for many countries and governments, and particularly on energy critical infrastructure protection. The international frameworks of the EU Directive 2008/114/EC and the U.S. National Infrastructure Protection Plan since 2009, is now accompanied by the recent approval in Spain of Act 8/2011 and Royal Decree 704/2011 on the identification and protection of critical infrastructures. In this article, on behalf of such references, different international strategies for infrastructure protection management are shown. A conceptual framework for risks identification in electric infrastructure through interconnected risk maps is also proposed.

Local electrical market based on a Multi-agent system

The rise of distributed generation makes more difficult the power balance between demand and generation in electrical networks, especially by the uncertainty of renewable generation. Smart grid concepts have been developed to solve this problem. A set of generators, loads and storage devices are locally managed to minimize the energy cost. These smart grids have surpluses and deficits of energy along time, so they have to interact in a local smart market. In this paper, we present a local smart market based on a multi-agent system. Every smart grid has a manager agent that minimizes its energy cost (intra-market). Then, it offers the surplus of energy or requests the deficit of energy to other neighbour smart grids. An auction allows fixing the energy and economical interchange among smart grids (inter-market). The manager agent can buy energy in the auction when it is cheaper than the energy of their own generators even if these generators have surplus of energy. A Multi-agent system has been developed in JADE platform.

Escenografía virtual de bajo coste para la docencia online - [Low-cost virtual scenography for online teaching]

The virtual scenography has been applied for years in films and television programs, achieving a substantial improvement in communication with viewers as well as a reduction in production costs. An example is the weather section in television news, where using chroma key the person appearing on the screen seems to have a map behind, although the map is not really there. In the field of teaching has a clear applicability, and in some universities already have facilities in which teachers can prepare and record presentations for online teaching using virtual scenography. Considering the characteristics and requirements of teaching presentations, this article presents a low cost and portable system whose main objective is to make presentations for online teaching using virtual scenography, including the presentation of some of the computer tools that can be used for video recording and subsequent editing.

Producción, Reservas y Sostenibilidad de la Energía en Venezuela

El proposito del presente trabajo esta relacionado con la evaluacion de los recursos energeticos de Venezuela y su posicionamiento estrategico mundial, referido principalmente a la produccion y consumo de energia primaria y reservas. Asi mismo se han evaluado los recursos energeticos renovables con la finalidad de identificar oportunidades para el desarrollo de la energia sostenible. Los resultados indican que Venezuela posee recursos fosiles para mas de 130 anos de explotacion, lo cual lo convierte en una potencia energetica relevante en el contexto mundial. La potencialidad aprovechable de las energias renovables duplico la produccion de recursos fosiles en 2011. En la actualidad, el aprovechamiento de estas fuentes es inferior al 2 % del total disponible, lo que deja abierto un amplio rango de posibilidades para la diversificacion de la matriz energetica nacional mediante tecnologias limpias o sostenibles
