Review on Energy Storage Systems Control Methods in Microgrids

Microgrids (MGs) are new emerging concept in electrical engineering. Apart from their many benefits, there are many problems and challenges in the integration of this concept in power systems such as their control and stability, which can be solved by Energy Storage Systems (ESSs). In this paper, an introduction to MG architecture and their challenges is initially presented. Then, important types of ESSs and a brief description of their characteristics are reviewed. Different ESSs operation configurations and their control methods are discussed as well. Different advantages and disadvantages of configurations and control methods have been discussed in the paper. A discussion about the control methods of ESSs and future trends are also presented. Investigation of different researches, shows that the control of ESSs has an effective role in different aspects of MGs such as stability, economic, etc.
