Optimization and analysis of an integrated energy system based on wind power utilization and on-site hydrogen refueling station

An integrated energy system coupled with wind turbines and an on-site hydrogen refueling station is proposed to simulate the future scenario, which can meet the demands of cooling, heating, power and hydrogen. The system was modeled to calculate the capacity and annual operation of each equipment with the total annual cost as the optimization objective. This study evaluates the performance of the system based on the results. When the system is configured with 0-10 wind turbines, the economics, energy consumption and carbon emissions improve as the scale of wind turbines increases. Energy utilization and wind power utilization are above 66.79% and 99.73%, respectively. The on-off coefficient of the power generation unit can affect energy efficiency. When the system contains 5 turbines, 91% of the hydrogen can be self-produced with the minimum amount of energy redundancy. & COPY; 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.

Automated summary

An integrated energy system consisting of wind turbines and a hydrogen refueling station is proposed to simulate future scenarios and meet cooling, heating, power, and hydrogen demands. The system's modeled calculations consider equipment capacity, annual operation, and optimization objectives regarding total annual costs. Performance evaluations of the system are based on the study's results. Increasing the scale of wind turbines (0-10) improves economics, energy consumption, and carbon emissions. Energy utilization and wind power utilization are above 66.79% and 99.73%, respectively. The on-off coefficient of the power generation unit affects energy efficiency. With 5 turbines, the system can self-produce 91% of hydrogen with minimal energy redundancy. ©2023 Hydrogen Energy Publications LLC. Elsevier Ltd. All rights reserved.
