Study on the driving force and challenges of developing power grid with high penetration of renewable energy

With the increase of energy demand and environmental awareness, It becomes an inexorable trend to develop and utilize renewable energy and to increase the proportion of clean energy in end use energy. The development of power grid in future should not only consider power demand but also accommodate large-scale renewable energy. This paper conducts a study on the development pattern of future power grid including high penetration of renewable energy. The driving force of developing power grid is analyzed though deducting its development process and exploring potential and dominant factor by using the experiences of European countries and USA for reference. Based on the above work, the requirement and challenges of future power grid are explored considering the specific characteristics of power grid development in China, and the key technical problems is figured out. Finally, potential development scenarios are presented regarding future power grid of China.
