Abstract—Distributed Generation (DG) is the use of small generating sets connected to the grid or feeding power islands, based on technologies such as internal combustion engines, small and micro turbines, fuel cell, photo voltaic and wind plants. Driven by increasing environmental concerns and increasing amount of new generation technologies, it is expected that many new generation technologies, including renewable generation, will be connected to electrical power system in the near future, therefore stability condition changes shall be studied to improve overall power system operation. In this paper the impact of DG on power system transient stability is investigated by genetic algorithm method. It is observed that both size and location of DG technologies will influence network stability. The fitness evaluation function that drives the GA to the solution is an integral of rotor angle oscillations versus time.
