Distribution system adequacy assessment with cosideration of stochastic distributed generation

One of the important role of distributed generation is demand supply near the customer location. Due to reducing the capital investment cost of power system upgrading, distributed generation utilization has economical benefits for utilities. Because of fossil fuel cost increment and environmental concern importance, renewable based distributed generation penetration rate in increased. Due to inherent variability of their primary energy, power system planning in presence of these resources requires special attention and suitable modeling of their power generation. In this paper, it has been supposed that additional required capacity with respect to substation capacity for supplying load should be provided by renewable based distributed generation implementation. Accordingly, power distribution system adequacy in presence of renewable based distributed generation is assessed using Monte Carlo Simulation in this paper.
