Electrical energy networks have become one of the world's most complex and comprehensive systems. Any change in the system like excess generation or loss of load affects the whole energy network. On the other hand, the use of renewable energy sources as green energy is rapidly spreading to the world. As the installed power capacity of these sources increases, its integration into the existing electricity grid has become a major problem. In this paper, Turkey's renewable energy potential is summarized and the challenges related to the integration problem have been considered in terms of Turkey electric energy network. Finally, some basic solution proposals are suggested.
