Analysis of the Impact of Distributed Generation on Power Grid

Aiming at the problem that distributed generation,an increasingly popular role in grid,accessing to grid is lack of corresponding technical analysis and evidence,this paper mainly studies impact of distributed generation in different types on grid..Distributed generation are classified from two categories of operating mode and interface mode in this paper firstly according to classification research.Then,its connection manner to power grid is analyzed with building a typical model of distributed network for basis.Finally,combined with the theoretical analysis and the case study,the impacts of the grid-connected distributed generation on power grid such as stable characteristics,power quality and the protection,issues are analyzed,which provides theoretical support for the modification of power grid guidelines.
