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 nonconventional 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.

Probabilistic assessment of wind power production on voltage profile in distribution networks

“…Wind generators impact is a growing issue in countries where it represents a high percentage of installed power, like in Spain, and of energy production, like in Denmark [9]. Then, new strategies are needed to accommodate wind power in normal operation.…”

“…Then, new strategies are needed to accommodate wind power in normal operation. However, these strategies will be difficult to different countries since their regulation and network characteristics are different, like it is shown in [9]. Therefore, it is better to investigate the impacts of wind power integration in power systems from a probabilistic approach than a deterministic one [7], [8], in order to gain a thorough understanding of its impacts on power quality.…”

The Actors of a Wind Power Cluster: A Case of a Wind Power Capital

“…8-9) identify wind turbine manufacturers and wind farm developers as the core players of a wind energy cluster. Villafafila et al (2007) define wind turbine manufacturers, part suppliers and research and educational institutions as the members of a wind power cluster. Besides the mentioned actors, Cornett and Sörensen (2011, p. 4) add business developers and the public sector to the cluster members.…”

Short-term voltage stability of fixed-speed wind turbines: Comparison of single and double cage

“…INTRODUCTION Wind energy is currently the fastest growing energy resource integrated into actual power systems. Although the overall proportion of wind energy in the European electricity system is still small, some countries like Denmark or Spain [1] have reached a high proportion of wind turbine generation systems (WTGS) in their networks. Therefore, WTGS should react during and after grid fault events so that the stability of the existing power system is not degraded.…”
