Technical pros, environmental constraints in addition to burgeoning body of economic incentives push boundaries of power industry toward growing employment of distributed generators (DGs). Although undeniable growth of DGs has reduced the need for development of the<br/>costly monopole traditional power systems, controlling a great number of small scale generators has become a delicate problem. Fortunately, promising concept of microgrids has recently emerged to cope with these problems. A microgrid is a part of distribution system including a number of DGs and local loads. Normally, it is operated connected to the main power grid system; however, it is able to be operated as an autonomous island due to contingencies or pre-planned sessions. The latter characteristic facilitates microgrids to perfectly promote power quality standards according to smart grids horizons responding to the growth of sensitive loads <ref>Raghami, A., Ameli, M., & Hamzeh, M.
