عنوان A Novel Fuzzy/SMC based Energy Management Strategy for Hybrid Energy Storage System in an Isolated DC Microgrid

نویسندگان Puria Safari - Ehsan Farrokhi - Hoda Ghoreishy

چکیده In this paper, a new energy management strategy (EMS) based on fuzzy logic and sliding mode control (SMC) is presented for hybrid energy storage system (HESS) in isolated DC microgrid. The proposed fuzzy method optimally divides the power/current between the battery and the supercapacitor (SC) according to the battery state of charge (SOC) and the required current range of the microgrid so that the bus voltage remains stable at the reference value. In addition, due to the inherent limitations of the PI controller, the sliding mode method has been used to control the converter switches in order to generate the specified current references. Finally, using simulation in MATLAB, the proposed method has been compared with an improved low-pass filter (LPF)/PI control method, and the superiority of the proposed method is proven.
