I am looking for a research paper on current status of the european electric grid and developments in close future. For now I only have to articles of "Agora-Energiewende"., a german group of researchers on this topic.
http://www.renewables-grid.eu/ (not a paper, but a web site with information about European developments in the smart grid)
