Special Issue Information

Dear Colleagues,

The large-scale integration of renewable energy sources into power grids has introduced significant challenges in terms of grid safety, stability, and power quality control due to their inherent stochasticity and intermittency. Hydrogen energy, as a high-efficiency and clean secondary energy carrier, demonstrates unique advantages in renewable energy utilization, enhancing grid flexibility, and complementing multi-energy systems. Through the electricity–hydrogen–electricity cycle, hydrogen energy enables flexible regulation across generation, grid, load, and storage systems. However, its technological development—from component R&D and system integration to field-level deployment—faces multiple bottlenecks and planning challenges due to its interdisciplinary nature, as it involves power electronics, materials science, chemical engineering, and automation control.

This Special Issue aims to present and disseminate cutting-edge advances in the integration of hydrogen energy into power systems, focusing on the mechanisms enabling synergetic "generation–grid–load–storage" frameworks, electricity–hydrogen–electricity conversion technologies, multi-scenario storage and flexibility control strategies, system planning with economic analysis, and the cross-disciplinary standardization of technology.

Topics of interest for publication include, but are not limited to, the following:

  • Green hydrogen production technologies and renewable energy coupling mechanisms;
  • Hydrogen fuel cell power generation and grid operation strategies;
  • Core hydrogen technologies and equipment development;
  • Multi-timescale regulation strategies for hydrogen-integrated source, grid, load, and storage systems;
  • Hydrogen backup power systems and grid black-start coordination in extreme scenarios;
  • Multi-energy collaborative planning for wind–hydrogen-storage-integrated mega-bases;
  • Dynamic scheduling and energy management in hydrogen microgrids with electricity–heat–hydrogen coupling;
  • Planning, scheduling, and economic analysis of hydrogen–ammonia–alcohol hybrid multi-energy systems;
  • Digital twin technologies and intelligent regulation for hydrogen–electricity coupled systems.

The electric–hydrogen coupled integrated energy system (EHCS) is a critical pathway for the low-carbon transition of energy systems. However, the inherent uncertainties of renewable energy sources present significant challenges to optimal energy management in the EHCS. To address these challenges, this paper proposes an energy management method for the EHCS based on an improved proximal policy optimization (IPPO) algorithm. This method aims to overcome the limitations of traditional heuristic algorithms, such as low solution accuracy, and the inefficiencies of mathematical programming methods. First, a mathematical model for the EHCS is established. Then, by introducing the Markov decision process (MDP), this mathematical model is transformed into a deep reinforcement learning framework. On this basis, the state space and action space of the system are defined, and a reward function is designed to guide the agent to learn to the optimal strategy, which takes into account the constraints of the system. Finally, the efficacy and economic viability of the proposed method are validated through numerical simulation. Full article
