In the evolving landscape of energy distribution, a novel optimization framework is making waves, promising to enhance the profitability and robustness of hydrogen refueling stations (HRSs) within integrated power-hydrogen distribution systems (IPHDS). This groundbreaking research, led by Md Mohaiminul Islam Mahin from the School of Electrical and Electronics Engineering at Chung-Ang University in Seoul, South Korea, introduces a dual-peak shaving approach that could redefine the operational dynamics of HRSs.
The study, published in the English-language journal “IEEE Access,” focuses on on-site HRSs equipped with photovoltaic (PV) systems, battery energy storage, electrolyzers (ELs), fuel cells, and multiple hydrogen storage tanks (HSTs). These components are crucial for maintaining reliable and cost-effective operations in IPHDSs while supporting the charging demands of hydrogen vehicles (HVs).
Traditional methods often rely on single HST-based HRSs and focus solely on power peak shaving. However, Mahin’s research proposes a more sophisticated approach. “Our optimization framework performs dual-peak shaving of both power and hydrogen through substations and ELs in multiple HST-based HRSs,” Mahin explains. This dual-peak shaving method is implemented using chance-constrained optimization (CCO) to address uncertainties in PV generation outputs and HV charging demands.
The research demonstrates that this innovative approach can significantly increase total profit. Numerical examples conducted on IEEE 33-node and 69-node power distribution systems with three and five on-site HRSs show that the proposed CCO method with multiple HSTs and dual-peak shaving increases total profit by an average of 5.88% and 8.19%, respectively, under varying HV charging demand adjustment periods and chance-constraint violation probabilities.
The implications of this research are substantial for the energy sector. By optimizing the operations of HRSs, this framework could lead to more efficient and profitable energy distribution systems. “This method not only enhances the economic viability of HRSs but also ensures reliable operations under uncertain conditions,” Mahin notes.
As the world moves towards cleaner energy solutions, the integration of power and hydrogen distribution systems becomes increasingly important. This research provides a promising avenue for improving the efficiency and profitability of these systems, potentially shaping the future of energy distribution and hydrogen refueling infrastructure.
In an era where sustainability and economic viability are paramount, Mahin’s work offers a glimpse into the future of energy management, where innovation and optimization go hand in hand.
