Abstract: Integrating hydrogen energy storage system (HESS) and battery energy storage systems (BESS) is crucial for enhancing energy reliability and sustainability, especially in renewable energy applications. These hybrid systems address the intermittency of renewable sources by providing efficient energy storage, thereby ensuring power quality. Power quality improvement, particularly in voltage stability and harmonic distortion reduction, is a key advantage of hydrogen-based systems and BESS. This study introduces a novel dual d-q (DDQ) control approach to enhance the performance of hybrid energy storage systems. DDQ is designed to optimize energy transfer and stability in grid-connected systems. As part of the evaluation, two control methods proportional-integral (PI) and decoupled d-q (DEDQ) control are employed as comparator techniques. The simulation results from the software platform reveal the superiority of the DDQ method, achieving an efficiency of 98 %, compared to 81 % for DEDQ and 12 % for the PI method. This substantial improvement in efficiency demonstrates the effectiveness of DDQ in managing power flow and maintaining high power quality in integrated hydrogen and BESS systems. The findings suggest that DDQ offers a significant advancement over traditional control methods, making it a promising approach for future hybrid ESSs.
