Abstract : Renewable energy system plays a major role in today's world of power deficits. The renewable power technologies keep fluctuating due to their dependence on natural phenomena. Using hybrid combinations, it is possible to meet the technological and economical requirements of the energy storage process. This paper proposes a hybrid energy storage system based on the superconducting magnetic energy storage System (SMES) and the lead–acid battery to provide power stabilization in the unreliable microgrid connected to the grid. The proposed system may be a good solution for minimizing the impact during fault condition on variability in power output at the point of common coupling (PCC). The two hybrid power sources are connected using dual input single output zeta (di-zeta) converter to improve efficiency and versatility of the proposed system. Grid-linked microgrid with SMES battery was simulated using MATLAB/Simulink platform and evaluated using an energy management algorithm with and without fault condition. The proposed system is demonstrated by comprehensive simulation results.
