The impact of distributed generation and its parallel operation on distribution power grid

The trend of distributed power application is more and more obvious Aiming at the problem of the lack of effective argument and the corresponding technical analysis in access system. Focus on all kinds of distributed power supply access after the results of the influence of the power grid operation. First of all, from the operation mode and the way of interface for distributed power supply is analyzed, so that the classification to study the effect of different results is easy. Then, analyse the connection way of the distributed power grid, build a typical distribution network model, as the basis of analysis of the distributed power access. Finally, by the theoretical calculation of the access model, analyse the effect on the steady state characteristics and power quality, thus providing theoretical basis for distribution network planning technology principle of modified.
