ABSTRACT
Due to the increasingly concern about environment, Distributed Generation (DG) system which contains new energy and renewable energy, has become an important technology in the construction of smart grid. To give full play to the advantages of distributed generation systems in terms of energy and environmental benefits, domestic and foreign scholars have carried out lots of studies, including analysis of energy conservation efficiency, harmful gases emissions from energy supply systems, and renewable energy utilization (Giri, J. 2009, Benjamin, Kroposki et al. 2010).
