This article presents the results of analyses of large-scale integration of wind power, photo voltaic (PV) and wave power into a Danish reference energy system. The possibility of integrating Renewable Energy Sources (RES) into the electricity supply is expressed in terms of the ability to avoid...

Some relevant patterns for the wave energy spatial distribution in the Portuguese nearshore are analyzed in this work. A medium term analysis of the wave climate in the target area was first carried out based on recent buoy measurements covering the 10-year period 1994–2003. A wave prediction...

Investments in renewable energy plants normally only take standard economic key figures into account, such as installed rated power, the market price of energy and the interest rate. The authors propose that the degree of utilisation, i.e. the ratio of yearly produced energy in the installation...
