A Novel Design of Fuzzy Logic Control Algorithm for Hybrid Energy Storage System

This paper investigates the control methodology of hybrid energy storage system (HESS)in the context of microgrid. It develops a novel fuzzy logic control (FLC)method for HESS aiming at minimizing power fluctuation between the microgrid and the external grid to deal with peak power demands and reduce the disturbance caused by distributed renewable energy sources. The model of microgrid HESS has been tested through Matlab/Simulink platform, and the performance of the novel fuzzy controller has been compared with that of a rule based controller (RBC). The effectiveness of the fuzzy control method were verified.
