Micro grid (MG) has become popular due to its ability to disconnect from utility grid during disturbance and operate autonomously. MG typically consists of three main parts, which are Distributed Energy Resource (DER), Energy Storage System (ESS) and load. MG has several benefits and one of them is to enhance the power system reliability and flexibility by balancing the supply and demand. The scarcity of fossil fuel and environmental concern has contributed to the growth of Renewable Energy Source (RES), which is one of the main elements in MG. However, the RES integration into MG has led to multiple uncertainties due to their inherent intermittency. Therefore, optimal strategies are essential to be employed in MG to manage and control the dynamic uncertainty introduced by the renewable-based DER and variable loads. In this paper, a comprehensive review is presented on the optimal allocation of the multiple DER in MG. various optimization methods are also investigated to solve the problems in MG. Furthermore, advantages and drawbacks of each optimization method are also reported.
