Abstract

This paper first analyzes the AC/DC hybrid microgrid operating characteristics and the mathematical model of the interface convertor according to the operation mode. Then it develops a control system for the interface convertor based on sliding-mode control (SMC). A reaching law is designed to ensure the performance of this control system. An experimental setup is developed based on dSPACE 1006. Simulation and experimental results illustrate that the control system is insensitive to parametric uncertainty or external disturbances. The fast dynamic response and robust control performance of the interface convertor can ensure the stable operation of the microgrid.
