Abstract

The distributed generation (DG) emerged as an ideal option deals with the growth in electricity demand. With such a new system there is always a chance of some transient disturbances. A transient can be caused by a number of power system switching events or faults such as lightning strikes, short circuits, or equipment failure. The purpose of this work is to identify the best location of DG connection and if the DG should be concentrated in one location or distributed among different location in distribution network as well as identifying the suitable DG penetration level that can be inserted without affecting the distribution system voltage stability or its power quality based on the European technical standard and the Standard for Interconnecting Distributed Resources with Electric Power Systems "IEEE-1547" standard. To achieve these goals, a transient simulation is developed for DG energization with different penetration levels and different locations on power distribution network to investigate voltage stability and power quality of the distribution system. The DG can greatly affect the voltage profile, reverse power flow, power quality, and so on. General purpose Alternative Transients Program (ATP) version of Electromagnetic Transient Program (EMTP) is used to accomplish the above goals. IEEE 13 node test feeder distribution system is used in this work.
