AbstractNow a days, the rapid need for electrical energy all over the world has put electrical power system under great stress. Due to day by day decrease in available conventional energy sources, researchers are shifting towards non-conventional energy resources or Dispersed generation (DG). DG is becoming a feasible alternative to overcome the power deficiency due to reduction in power losses, system reliability, and availability of power at consumer’s premises. With this need of DG, it’s important to analyze the adverse impact of DG on distributed power system. This research analyzes the effects of induction generator and synchronous generators on distribution system. The main outcome and objective of this research is to find optimum type, size and placement of DG to be injected in distributed system in order to have minimum impact on power losses of the system. By using globally renowned and modern software Electrical Transient Analyzer Program (ETAP) and taking Rahman Baba electricity distribution network as a test case. After analyzing, the results show that injecting DG has positive impacts on power losses at certain buses while 30% of power losses were decreased when induction generator as a DG unit was integrated with the distribution network in the optimum location. Also positive impacts of DG unit on power losses has been seen by injecting undeterministic small amount of synchronous generator as a DG unit and by increasing cross-sectional area of the conductor has showed much improvement in power losses.
