Environmental pollution is a modern phenomenon arising from human activities.  Industries have caused the most pollution in living spaces around them. Releasing industrial effluent without environmental purification process faces countries to the issues such as disposal and destruction problems, while the imposition of high social, health and environmental costs on society are the most important problems. In the cases where there are industries around the cities, due to lack of proper purification system, large volumes of wastewater enter the environment daily. Among these materials, we can mention Vinasse, which is an effluent of the alcohol production plant and is an organic material.  This organic material is decomposed in the environment and causes an unpleasant odor in the Ahvaz, Khorramshahr and Abadan metropolises air. It is possible to produce Biogas through Vinasse anaerobic digestion. In this paper, we studied the construction of the biogas distributed generation plant based on anaerobic digestion Vinasse. Calculations show that using the biogas produced from the approximately 396,000 cubic meters of available Vinasse it is possible to build a 2-MW power plant and produce 11.5 GW of electricity per year. In addition, simulation of the global power network in the intended area using Digsilent software, shows that connecting the biogas power plant to the grid, reduces power losses and transformer loading, and improves the voltage profile and voltage stability limit.
