Characteristics and Control Strategies of Composite Energy Storages in Microgrids
This paper firstly introduces the standard models and key control techniques of microgrids. And then the battery energy storage and superconducting magnetic energy storage (SMES) charge-discharge principles and control strategies are discussed, and further more build the simulation models in PSCAD/EMTDC to analyze dynamic characteristics. A combination of energy storage model is built based on the different characteristics, and realize the unity of control. The study is focused on the operational characteristics of microgrids and composite energy storages during the process of connected operation switching to isolated operation and again to the connected operation. The results show that the composite energy storage has both the two energy storage advantages, it can response rapidly, balance the power flow, stable voltage fluctuation and meet the load demand of power supply. It ensures the stable operation of microgrids.
