Nature.com | January 2025

Abstract

A hybrid microgrid powered by hydrogen is an energy infrastructure that depends on hydrogen as its primary energy carrier within a localized network. This study proposed a novel bi-level optimization approach to enhance power quality and cost efficiency of the system. In the quest to improve energy management systems (EMS) and enhance power quality, a bi-level optimization approach named Particle swarm optimization-Modified water wave optimization (PSO-MWWO) has been proposed. This method integrates adaptive population size and an adaptive wavelength coefficient to boost its overall effectiveness. It is attractive with specialists in energy management systems (EMS), control systems, and hydrogen technologies can significantly augment the efficiency of coordination endeavours. PSO-MWWO can incorporate environmental considerations, such as minimizing emissions or exploiting the use of renewable energy resources (RESs) in hydrogen production and consumption. This paper thoroughly examines its implementation, operation, and unique features, with a particular emphasis on the power quality of a hydrogen based microgrid. The achieved results and numerical analysis affirm the superiority of the proposed technique compared to other traditional methods like mixed integer linear programming (MILP), HOMER, Variable mesh optimization (VMO), and Cataclysmic genetic algorithm in optimizing component sizing, renewable production, hydrogen production, reliability, cost effective, and overall efficacy. This substantiates its practical utility in real-time applications. The efficacy of this method is empirically demonstrated through the implementation in MATLAB software...

Hybrid grids is an emerging technology and concept that embraces substantial potential for addressing some of the encounters associated with renewable energy integration and grid steadiness8,9,10. Hydrogen is considered an energy carrier and storage key for power grids. It can store surplus energy when supply exceeds demand and consume it when required, helping to balance the grid supply11...

Conclusion

This article introduces a novel approach for hydrogen based microgrids that serve for cost-effectiveness and improvement in power quality, which is ignored by the other scholars. The proposed approach tackles the shortcomings of conventional hydrogen based microgrid designs by integrating the selection of energy conversion structures and the sizing of energy sources into an integrated design framework. The planning process incorporates performance metrics like cost and power quality. Compared with other conventional researches on daily basis and it is found that its much advantageous. This article also provides a strategy for power convergence to validate the efficacy of this new technique. Through simulation, the assessment shows that power convergence enhances the quality of hydrogen-based microgrid systems, resulting in improved performance for hybrid microgrid regarding cost-effectiveness. The proposed method achieved savings of approximately 6.867% of the total cost by incorporating bi-level optimization. With a focus on power quality, this study has realized an impressive 94.9% improvement in cost-effectiveness by using bi-level optimization compared to previous methodologies.

Future research will concentrate on optimizing power delivery to consumers in hydrogen based microgrids, aiming to enhance society’s access to carbon-free energy sources. This paper has established the significance and engineering utility of System-based energy management for hydrogen based microgrids. Moreover, it lays the foundation for prospective research in the future. For instance, it opens the door for comprehensive optimization of both the microgrid system’s sizing and operation, which should be derived from the energy management methodology introduced in this study...more
