Missed elements of microgrids

Considering the importance of the role of microgrids in developing Smart Grids in the form of smart cities or islands, there is many attempts to model their behavior for different power system studies [1-2]. This paper tries to pay attention to the elements of microgrids, which have not been discussed in details in literature but they are important for estimation of the microgrids behavior under different circumstances. The paper focuses on three of these elements.
