چکیده

The source of distributed generation based on the restructuring in the power industry and creating the power market and making the energy production competitive, the future energy system of humans will provide the heating, cooling needs and power. The reduction of losses of distribution networks is the most important priority in the design and utilization of the country's power networks. Using the source of distributed generation results in a significant reduction in the active and reactive losses of the lines (in case of source ability in reactive power generation) and reliability improves. The profile of buses voltage is reached in the amount of per unit and create a suitable security margin for the voltage value. The security of the system is increased in the face of events and the amount of network off times is decreased. According to the extensive and appropriate impact which the DGs have on the distribution system and have on the other transmission lines naturally, using these sources in the distributed network is an appropriate practice. In this study, by using the DigSilent software the impact of this network is examined. Losses, reliability, voltage profile and harmonics are the issues that have been compared with and without DG. By assessing the results through the software it is observed that using distributed generations and optimal placement and choose appropriate capacity for them, can decrease the losses of sub-transmission and transmission.
