Portugal

In Portugal, 2012 was an atypical year in Portugal with regards to energy. Due to the efficiency measures implemented in recent years, but also due to the economic recession, electricity consumption in Portugal dropped 3.6% to 49.1 TWh. This represents a reduction of 6% of electricity demand in the last two years (1). It was also an extremely dry year, the fifth driest hydro year of the past 80 years (63% below...

Validation of an offshore wind atlas using the satellite data available at the ...

In this study a validation methodology for regional mesoscale model simulations when ingested with surface wind data inferred from satellite sources around Continental Portugal is evaluated. Observational wind data from a “quasi” offshore anemometric mast located in the Berlenga Island – near Peniche region – was used for the validation study. Satellite sources of wind data under assessment are the ones being u...

Portugal

During 2011, Portugal experienced a strong reduction of electricity demand. With a decrease of 2.3%, the total consumption was 50.5 TWh (1). Due to a mild winter season, the most relevant renewable generation facilities (hydro and wind) experienced a strong production reduction in comparison with 2010. In 2011, Portuguese wind farms produced 21 GWh less than the previous year. It is only because of the decrease...

Offshore wind field: Application of statistical models as a spatial validation ...

Generally, atmospheric mesoscale models are used as tools to perform wind atlases. In recent decades, significant efforts have been applied to the development and improvement of this kind of models to reduce their systematic errors. These ones are assessed when model results are compared with observations. In practice, such errors could be statistically corrected if observational data was available for the same...

Integração de sistemas de energia renovável a instalações residenciais

Os sistemas de microgeração domésticos que produzem energia a partir de fontes renováveis necessitam de legislação especifica e de ferramentas para identificar os potenciais e a viabilidade de implantação de soluções tecnológicas adaptadas ao ambiente urbano. Este artigo analisa exemplos de implementação de sistemas eólicos, fotovoltaicos e híbridos em uma edificação, debatendo questões económicas e energéticas.

MOS – “Model Output Statistics” – Aplicação da metodologia para correcção das p...

A previsão do vento com exactidão é actualmente uma ferramenta necessário para a análise do potencial e estimativa de produção de energia eólica. Apesar do progresso significativo nos modelos de previsão meteorológica, os modelos apresentam erros sistemáticos que podem ser corrigidos com a aplicação de modelos estatísticos, lineares ou não, a partir das estatísticas acumuladas de um certo modelo de previsão. Es...

Integration of renewable energy systems in buildings in the line of sustainable...

Being Portugal an extremely active country on the renewable energy area, one of technology niches experiencing a growing interest from investors and population in general are domestic micro-generation systems, especially when integrated in a building’s architecture. As a response to the expectations developed among domestic end-users of distributed renewablebased micro-generation systems, by the end of 2007, th...
