چکیده

Abstract – Distributed generation (DG) technology is known as an efficient solution for applying in distribution system planning (DSP) problems. Load growth uncertainty associated with distribution network is a significant source of uncertainty which highly affects optimal management of DGs. In order to handle this problem, a novel model is proposed in this paper based on DG solution, considering load uncertainty. This model is designed to minimize network costs including operation and losses.  Genetic algorithm is used with the purpose of finding the optimal places, sizes as well as times for DGs. Load uncertainty is also modeled through Markov tree. To illustrate the effectiveness of the proposed model, it is tested in different scenarios considering the effects of the purchased power price, DG penetration factor and DG operation intervals. These scenarios are conducted in two different phases, with and without uncertainty and the results are then compared and discussed. Moreover, by considering load uncertainty in planning, planning models would be robust against network future load variations.
