This paper presents a method of determining the location and size of distributed generation (DG) considering to operate the configuration of distribution network to minimize the real power loss. The proposed method which is based on the genetic algorithm (GA) is divided into two stages. In the first stage, GA is used to optimize the location and size of DG in the mesh distribution network, while in the second stage, GA is used to determine the radial network configuration after installing DG. The simulation results on the 33-nodes and 69-nodes systems show that the proposed method can be an efficient method for the placing DG problem and that is considering to solve the problem of distribution network reconfiguration.

A new relay protection based on electronic communication is presented for the access of distributed generation. After distributed generation access to the system, distribution network power flow direction and short-circuit current level will change. This paper describes the effects of distributed generation on distributed network by building feeder system simplified PSCAD/ EMTDC model. According to the analysis, the new relay protection can improve the stability and reliability of distributed network.

Compared with the traditional power system, there are some differences in the aspect of distribution network structure, line parameters and load parameters in the power system with distributed generations. Therefore, the conventional power flow algorithm can not be applied to this kind of networks. Considering that the distributed generations have special influence on the operation of distributed network, a novel power flow calculation method for this kind of distribution network is studied in this paper. Several equivalent circuit models of distributed generations and the corresponding approaches have been researched. The feasibility of this proposed power flow algorithms can be verified through the program designed in Matlab software.

Voltage Support

It brings all kinds of negative and positive impact on distribution network with the distributed generation connection. Feeder voltage of the distribution network will be affected. Distributed generation can play a good supporting role to the feeder voltage, which also can make feeder voltage exceed the maximum safe voltage. The details have an important relationship with the capacity, size and location of distributed generation. The voltage supporting model and voltage calculation method of distributed generation connected with distributed network is given in the paper. The IEEE 34 Node model was chosen to be discussed how different factors can influence the feeder voltage. This paper analyzes distributed generation’s influence to the distribution system voltage level.
