On wind power integration into electrical power system: Spain vs. Denmark

Abstract

Economic, social and environmental concernsdemand higher efficiency and more sustainable electrical powersystems. Then, power systems need to evolve from itstraditional conception to future power systems. New non- conventional generators are distributed in power systems, mostof them based on renewable resources, which have beendeveloped and connected to the grid. Wind power is nowadaysconsidered as one of this future renewable energy sources and itis more and more spread over the world. But there are a numberof technical issues to be solved in order to accommodate thesenew units. Moreover, technical grid code requirements andregulations vary considerably from country to country.Denmark is the leader in wind power integration anddevelopment, and it is considered as a pattern to be followed. Wind power in Spain is also important. However, there aresome facts between both countries that cause importantdifferences. This paper points out some of them and suggests some strategies to be dealt with regarding wind power integration in Spain
