This paper describes a hybrid fuzzy-sliding control scheme for bi-directional SEPIC converter in renewable based DC microgrids.The performance of a DC microgrid is directly dependent on the voltage stability of the DC bus.In operation, the voltage level of the system is affected by the power injection of the power sources connected to the microgrid, in particular those dependent on environmental factors (such as sun and wind), and by the power consumption of non-constant loads.This feature of microgrids makes control a complex engineering problem.Considering this problem, we propose a hybrid control scheme for a SEPIC bi-directional converter capable of regulating the power flow and stabilizing the system's DC bus.Proposed control technique is simulated in a 48 V DC microgrid and results are provided.
