Study on Smart Energy Storage Technology and Control Strategy in Micro-Grid

Energy storage technology is an indispensable support for reliable operation of micro-grid (MG). Various forms of energy storage system (ESS)’s application in MG are summarized; as energy storage is not easy enough to use, the development of smart energy storage is necessary. The concept of smart energy storage is proposed. The potential topologies of smart energy storage is given and analyzed, and some crucial control technologies of smart storage are also provided, including charging/discharging control method, power flow distribution control method. The principle of a novel designed power charging/discharging control method of ESS is illustrated, and the effectiveness of the method is verified with simulation results in PSIM.
