Effect of voltage deviations on power distribution losses in presence of DG technology

Integration of distributed generation (DG) units in power distribution network has become increasingly attractive multi-faceted paradigm as economic and environmental factors drive new technologies to be more efficient and less polluting than their earlier counterparts. The installation of DGs impacts critically on the planning and operating characteristics of the distribution network. Type, location, number and capacity of DG are essential factors for studying the effect of DGs on the system behavior. In this paper the effect of DG on the power losses of a distribution network is investigated for different types of DG units. Also, the impact of DG on the voltage profile is demonstrated before and after the reconfigurations due to the change in the loading conditions caused by the faults. Moreover, the voltage deviations for different contingencies are evaluated in order to choose the optimal DG location and capacity in the test radial distribution network.
