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

Abstract

Economic, social and environmental concerns demand higher efficiency and more sustainable electrical power systems. Then, power systems need to evolve from its traditional conception to future power systems. New non-conventional generators are distributed in power systems, most of them based on renewable resources, which have been developed and connected to the grid. Wind power is nowadays considered as one of this future renewable energy sources and it is more and more spread over the world. But there are a number of technical issues to be solved in order to accommodate these new units. Moreover, technical grid code requirements and regulations vary considerably from country to country. Denmark is the leader in wind power integration and development, and it is considered as a pattern to be followed. Wind power in Spain is also important. However, there are some facts between both countries that cause important differences. This paper points out some of them and suggests some strategies to be dealt with regarding wind power integration in Spain.
