It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more. So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system. The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.
