A review of drivers, benefits, and challenges in integrating renewable energy sources into electricity grid

This paper presents an overview on both current electricity grid and future grid. Experts believe that in future more distributed generation (DG) will be integrated into the low to medium electricity grid. This paper will also review the key drivers in relation to integration of increased DG technologies in general and the renewable energy-distributed generation (RE-DG) technologies in particular, into the electric power system and the opportunities and challenges linked to these technologies. This paper also reviews possible connection location of RE-DG into the grid and its impact on system voltage.
