Road-domain Integrated Energy System Planning Strategy Considering Hydrogen Storage and Demand Response

With the increasing demand for electric-hydrogen charging of vehicles and the multi-energy consumption in high-speed service areas, building a road domain integrated energy system can effectively meet the multi-energy demand and enhance the acceptance of renewable energy. Therefore, a planning method for the road domain integrated energy system containing hydrogen storage and demand response is proposed. Firstly, the road domain integrated energy system framework is constructed based on the analysis of energy flow of multi-energy conversion and hydrogen storage equipment such as electrolytic baths, hydrogen fuel cells, and air conditioners. Secondly, the Monte Carlo method simulates the disorderly charging behavior of vehicles in the road domain integrated energy system. At the same time, the hydrogen storage and demand response are introduced to excavate the potential of electricity-heat (cold)-hydrogen load. Then, a multi-objective planning model for the road domain integrated energy system is constructed to optimize economy, stability, and users' comfort. The (non-dominated sorting genetic algorithm II, NSGA-II) and commercial solver Gurobi is used to solve the model and, through simulation, verify the model's effectiveness. Finally, the planning results show that after introducing hydrogen fuel cells and demand response, the wind and solar power consumption rate improved, the wind and solar generation capacity increased by 4.45% and 12.24%, and the system total cost decreased by 17.27%. After introducing the multi-objective planning method, considering system stability, economy, and user's comfort, the system stability is improved by 0.26%, the system total cost is increased by 4.26%, and the users' comfort is reduced by 0.09%, which provides a reference for resource planning of road domain integrated energy systems with hydrogen storage. © 2024 Power System Technology Press.
