A research on influences of wind and solar power generation system on the grid and the control strategies

Wind power and solar energy will play a more and more important role in enhancing our country´s energy supply diversity, upgrading energy safety and improving the energy resources restructure. This article is to research into the advantages of wind and solar power generation system and possible grid problems. Present research results at home and abroad are also proposed. And then, design approaches and principles for co-ordination control of the system are to be delivered.
