In this paper, an optimal integrated inner controller is designed for the microgrid primary control level. The main task of the primary control level is to maintain stability and proper power sharing in microgrids. Non-optimal controllers have been generally used to design the inner controller in this level in the majority of researches. On the other hand, accurate and complete models of microgrids can be obtained. Therefore, it is an advantage to use the model based optimal control approaches. In this paper, an optimal inner controller is designed to simultaneously control of the microgrids voltage and current using a technique called linear quadratic tracking controller (LQT). In order to evaluate the performance of the proposed controller, it is applied to a microgrid including two distributed generators (DGs) in MATLAB/Simulink. Results of the simulations illustrate the proper performance of the controller in comparison with conventional methods.
