Highlights

  • Integrating P2X facilities, a community-level energy hub acts as a prosumer.

  • A P2X energy hub is analysed numerically under different market access levels.

  • P2X increases the deployment of local renewables.

  • P2X reduces the trading volumes between the hub and wholesale electricity market.

  • A profitable P2X energy hub relies on sufficient renewables and retail H2 market.

摘要

本文分析了在社区层面上的能源中心的运作,它有一个综合的P2X设施,并能进入能源市场。在本案例中,P2X允许将电力转换为氢气、热能、甲烷,或重新转换为电力。本文认为能源中心是一个大型的专业消费者,在市场上既是生产者又是消费者。本文研究了在2050年长期强烈的气候假设下,这样的P2X能源中心如何在电力市场上进行最佳交易并满足当地的能源需求。为了进行数值分析,本文使用了瑞士一个山村的案例研究。本文的主要贡献之一是量化了这种P2X能源中心的盈利运作的关键条件。特别是分析了不同程度的自给自足和当地可再生资源的不同可用性等影响因素对利润和运营模式的影响。此外,还评估了进入实时批发市场的电价信号和未来氢气零售市场的情况。P2X能源中心成功运作的关键因素被认为是充足的当地可再生资源和进入氢气零售市场。结果还显示,P2X的运行导致了当地可再生能源部署的增加,特别是在初始部署较低的情况下;另一方面,季节性储存起到了从属的作用。此外,P2X为社区降低了电力批发市场的交易量。

Abstr act

This paper analyzes the operation of an energy hub on a community level with an integrated P2X facility and with access to energy markets. In our case, P2X allows converting power to hydrogen, heat, methane, or back to power. We consider the energy hub as a large prosumer who can be both a producer and consumer in the markets with the novelty that P2X technology is available. We investigate how such a P2X energy hub trades optimally in the electricity market and satisfies local energy demand under the assumption of a long-term strong climate scenario in year 2050. For numerical analysis, a case study of a mountain village in Switzerland is used. One of the main contributions of this paper is to quantify key conditions for profitable operations of such a P2X energy hub. In particular, the analysis includes impacts of influencing factors on profits and operational patterns in terms of different degrees of self-sufficiency and different availability of local renewable resources. Moreover, the access to real-time wholesale market electricity price signals and a future retail hydrogen market is assessed. The key factors for the successful operation of a P2X energy hub are identified to be sufficient local renewable resources and access to a retail market of hydrogen. The results also show that the P2X operation leads to an increased deployment of local renewables, especially in the case of low initial deployment; on the other hand, seasonal storage plays a subordinated role. Additionally, P2X lowers for the community the wholesale electricity market trading volumes.
