Challenges of Danish power system and their possible solutions

Integration of renewable energy especially wind energy to existing traditional power systems across the world has attained tremendous growth since last two decades. However the unpredictable nature and inter-temporal variation of wind brings many technical challenges for large scale renewable energy integration like power regulation, frequency stability, voltage stability, unit commitment and economic dispatch. This paper attempts to highlight the main sensitive technical challenges of renewable Energy integrated power system in general and wind integrated Danish power system in particular. Possible solutions to these challenges are addressed in this paper for secure accommodation of large scale renewable energy. Future transformation of overhead to underground transmission network in Danish power system and associated challenges along with alternative solutions are also reported in this paper.
