Maximum loading point in distribution system with renewable resources penetration

In the recent years a large power oscillation have being seen in the distribution power system as a result of the integration of distributed generation resources (DGs). So a static and dynamic modeling of this system must be understood in order to ensure the reliable operation of the distribution system. The purpose of this paper is to study the effect of various small scale DG types on the voltage stability and the overall system loadability. The study has been carried out using the IEEE 33-Bus radial distribution system. Continuous power flow method is used to test the increasing loadability margin and it is found that the type of DG units significantly decreases or increases the loadability margin of the power distribution system.
