| Abstract | ||
| This paper presents an innovative hybrid energy system topology including a solid oxide fuel cell (SOFC) and a battery energy storage system (BESS) to improve the operation of solar photovoltaic (PV) and wind turbine generator-based renewable energy systems. A lithium-ion BESS was specifically chosen due to its high energy density and quick response time for short-term power support, which counteracts transient disturbance, and allows the grid to stay stable during the rapid fluctuations of renewable power generation. Thus, the SOFC is able to operate in steady-state mode to offset the longer-term intermittency of wind and solar resources. The excess energy produced by the PV panels is stored internally inside the BESS to be dispatched later. A complete system model was designed and simulated based on Simulink software to examine the performance characteristics of the proposed hybrid system. Simulation results validate significant improvements in overall system stability, reliability, and power quality, thus mitigating the negative impacts of renewable energy intermittency. Furthermore, a thorough economic examination demonstrates that the proposed SOFC-BESS hybrid system achieves considerable cost reductions compared to other renewable energy configurations. Most importantly, the system depicts a reduction in mean primary cost of almost 24% as compared to an average PV system made up of an inverter and a battery. Once more, a cut in cost of almost 30% is observable when compared with an average stand-alone standard wind turbine system. | ||
