摘要

传统的多能建筑主要关注能源成本的经济优化,而能源耦合的复杂性和能源成本/风险的冲突往往被忽视。考虑有限的生产灵活性,对P2A多能建筑进行模糊成本风险管理。在该模型中,基于P2A电解热电化学效应,利用了太阳风的多能互补性,并通过能量枢纽进行转换和调节。混合动力汽车(hev)被设想为多能源负载,并通过一种新的实时多能源供需定价机制进行管理。考虑了有限的氨生产灵活性,并将其建模为一阶过渡,以捕捉P2A的动态调节过程。制定的成本-风险管理问题是使用均值-方差方法来阐明与预测不确定性相关的风险,随后通过模糊优化来解决,以实现两个相互冲突的目标之间的权衡。在一个社区建筑环境中实施的仿真分析验证了该方法的优越性和有效性,成本降低12.03%,生产柔性建模提高19.25%。

Fuzzy Cost-risk management of HEV-penetrated power-to-ammonia multi-energy buildings considering the limited production flexibility
The traditional multi-energy building generally focuses on economically optimizing the energy cost, whereas the increasing complexity of energy couplings and conflicting energy cost/risk are often overlooked. This paper proposes fuzzy cost-risk management of a power-to-ammonia (P2A) multi-energy building considering the limited production flexibility. In this model, the solar-wind multi-energy complementarities are exploited on the basis of P2A electrolytic thermo-electrochemical effects, which are converted and regulated via an energy hub. Hybrid electric vehicles (HEVs) are envisioned as multi-energy load and managed through a novel real-time multi-energy supply–demand pricing mechanism. The limited ammonia production flexibility is considered and modeled as a first-order transition to capture the dynamic regulation process of P2A. The formulated cost-risk management problem is captured using the mean-variance method to articulate the risk linked to forecasting uncertainties, which is subsequently addressed through fuzzy optimization to achieve a trade-off between two conflicting objectives. Simulation analyses implemented in a community building environment validate the superiority and effectiveness of the proposed approach, achieving 12.03 % cost reduction and 19.25 % improvement of production flexibility modeling.

期刊介绍: The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
