With the increased penetration of renewable energy, maintaining the power system stability under abnormal operating conditions has become a major challenge. In PV system when fault occurs, power transmitted to the grid will be affected thereby reducing the power quality. This problem can be overcome if the main grid have a renewable based support, and possess the capability to feed the load during fault condition. A combined energy storage system based on Super Conducting Magnetic Energy Storage (SMES) and lithium ion battery is proposed in this paper which helps to improve the power stabilization in grid connected microgrid during fault conditions. The proposed energy management algorithm effectively minimizes the fluctuations in the power output at the Point of Common Coupling (PCC) during fault condition. Using MATLAB/SIMULINK, grid connected microgrid with SMES-battery was simulated and various performance analysis were conducted with and without the presence of fault under the proposed energy management algorithm. The effectiveness of the proposed energy management algorithm is verified by sufficient simulation analysis.
