Abstract

This article presents a coordinated operation model for energy management of a multi-integrated energy system based on Mixed-Integer Linear Programing (MILP). The power derived by trains from regenerative braking energy (RBE), during deceleration, is utilised to meet the interconnected energy hubs’ (IEHs) demand. The recovered energy is calculated by simulating the motion of the trains in MATLAB software. The electricity and heat demand response (DR) programs are integrated into the proposed model to study their impacts on the operating cost and the carbon emission of the IEH, considering several case studies. Furthermore, the uncertainties of the RBE, photovoltaic power generation, and loads of the IEH are considered by formulating the optimisation problem stochastically through a scenario-based approach. Therefore, a scenario generation and reduction decision-making technique is employed. Finally, the GAMS optimisation software is used to assess the efficiency of the presented MILP model. The simulation results indicate that the total operating cost of the IEH reduced 2.0% and 1.4% in the case studies. Also, the CO₂ emission is decreased by about 0.3% by applying the coordination scheme besides the DR programs.

考虑再生制动利用的综合能源枢纽的优化协调运行

Seyed Saeed Fazel，Narmak，德黑兰，16864，伊朗德黑兰。电子邮件：fazel@iust.ac.ir摘要本文提出了一个基于混合整数线性规划（MILP）的多集成能源系统能源管理协调运行模型。列车在减速期间从再生制动能量（RBE）中获得的动力用于满足互联能源枢纽（IEH）的需求。通过在MATLAB软件中模拟列车的运动来计算回收的能量。电力和热量需求响应（DR）计划被整合到拟议的模型中，以研究其对IEH运营成本和碳排放的影响，并考虑几个案例研究。此外，通过基于场景的方法随机制定优化问题，考虑了RBE、光伏发电和IEH负载的不确定性。因此，采用了场景生成和缩减决策技术。最后，使用GAMS优化软件来评估所提出的MILP模型的效率。仿真结果表明，在案例研究中，IEH的总运营成本分别降低了2.0%和1.4%。此外，通过在DR计划之外应用协调方案，CO2排放量减少了约0.3%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
