Study On Distributed Generations Connected To The Grid

Distributed generations (DGs) are normally small generation units installed in distribution system near customers. Distributed generation connected to the grid is beneficial to increasing power network reliability but may bring certain influence on power networkFor an in-depth study of the distributed generation(DG) and its on the power system connected this paper introduces the development and present status of distributed generation presents the concept classification and features of the DGand studies its efects on the power system in terms of the connection with the power grid voltage regulation harmonics and relay protection etc.This paper also study the relevant provision and technical standard on distributedgeneration interconnection preliminarily,and introduce direct connection,branch line connection and special line connection of DG with the physical project for example,by analysis and comparison of the plan, find out the suitablely connection pattern.An appropriate approach and solution to the connection of the DG with the grid helps further development of the DG the DG as a key supplementary element to the traditional power supply can be made full use, and it can play an important role in the comprehensive utilization of energy resources,.,, , ,, , ,..
