Quantifying the benefits of DG units in distribution network systems

Today, with the rise in global energy consumption and thus increase its production CO₂ emission has increased sharply. Research shows that one third of the total CO₂ emissions are from power plants. Based on the analysis of Energy Technology Perspectives (ETP2008) unless we find an effective way of decreasing CO₂ level there will be a 130% increase in CO₂ emission by 2050. There are many solutions suggested for preventing the excessive production of environmental contaminants such as increasing energy efficiency, utilizing distributed generators and renewable energy sources. The present study in addition to further introducing distributed generation systems as an effective method for energy production, aims to identify useful indexes for the assessment of these systems in the network, in terms of voltage, losses and environmental impacts. Then a model will be introduced for the assessment the impacts these systems have and also evaluation of the resulted financial benefits for consumers, energy companies and the general community. In the end results of the placement of photovoltaic generators as a type of distributed generation will be evaluated.
