本文提出了一个全面的研究，重点是在综合能源系统（IES）的协同定位风能和氢能集成的技术经济分析。该研究调查了四个不同的案例，每个案例都探索了风电场，电解槽，电池，储氢罐和燃料电池的各种配置。为了获得最佳的结果，该研究采用了一个复杂的数学优化模型，制定为一个混合整数线性规划。该模型有助于确定最合适的组件大小和每小时能源调度模式。该研究利用不同地区的历史气象数据和批发市场价格作为输入，增强了研究在不同地理位置的适用性和相关性。此外，还进行了敏感性分析，以评估氢气价格、区域风廓线和组件价格未来潜在波动的影响。这些分析提供了宝贵的见解，在不同的市场条件和不确定性下，拟议的IES配置的稳健性和灵活性。研究结果揭示了具有成本效益的系统配置，战略组件的选择，以及对未来能源情景的影响。具体来说，与只有风能和电池组合的配置相比，我们发现，加入电解槽可以使IES的总成本降低7%，而利用氢气作为燃料电池的存储介质可以降低26%的成本。此外，具有混合氢和电池储能的IES实现了更高和稳定的功率输出。该研究有助于决策，风险缓解和优化投资策略，促进可持续规划，以实现弹性和环境友好的能源未来。
This paper presents a comprehensive study that focuses on the techno-economic analysis of co-located wind and hydrogen energy integration within an Integrated Energy System (IES). The research investigates four distinct cases, each exploring various configurations of wind farms, electrolyzers, batteries, hydrogen storage tanks, and fuel cells. To obtain optimal results, the study employs a sophisticated mathematical optimization model formulated as a mixed-integer linear program. This model helps determine the most suitable component sizes and hourly energy scheduling patterns. The research utilizes historical meteorological data and wholesale market prices from diverse regions as inputs, enhancing the study's applicability and relevance across different geographical locations. Moreover, sensitivity analyses are conducted to assess the impact of hydrogen prices, regional wind profiles, and potential future fluctuations in component prices. These analyses provide valuable insights into the robustness and flexibility of the proposed IES configurations under varying market conditions and uncertainties. The findings reveal cost-effective system configurations, strategic component selections, and implications of future energy scenarios. Specifically comparing to configurations that only have wind and battery combinations, we find that incorporating an electrolyzer results in a 7% reduction in the total cost of the IES, and utilizing hydrogen as the storage medium for fuel cells leads to a 26% cost reduction. Additionally, the IES with hybrid hydrogen and battery energy storage achieves even higher and stable power output. This research facilitates decision-making, risk mitigation, and optimized investment strategies, fostering sustainable planning for a resilient and environmentally friendly energy future.
