Exploitation and implementation of renewable energy can substantially advance development, improve energy security, and alleviate the climate change problem. Integrating multiple renewable energy sources with grid power could potentially reduce the dependency on nonrenewable energy sources. However, because of the intermittent nature of the former, a tight integration between the supply and demand side management is necessary to facilitate uninterrupted power distribution and efficient energy consumption. This paper discusses an optimization framework that integrates supply and demand side management with application toward an energy-intensive cryogenic air separation process that is equipped with an in-house power generation system comprising multiple renewable and deterministic power sources as well as an energy storage system. The proposed framework integrates the power generation and purchase decisions along with the production complexities of the air separation plant (ASP). The optimal power generation schedule and the optimal production schedule provided by the proposed integration framework have been shown to minimize the total energy cost required to operate and meet the production requirement of the cryogenic ASP. An economic analysis is also performed to study the economic viability of including an in-house renewable source-based power generation and storage system with the ASP.

使用可再生电源的供需侧管理集成：在空分设备上的应用

开发和实施可再生能源可以大大促进发展，改善能源安全并缓解气候变化问题。将多个可再生能源与电网电源集成在一起可以潜在地减少对不可再生能源的依赖。但是，由于前者的间歇性，因此有必要在供需侧管理之间进行紧密集成，以促进不间断的配电和有效的能耗。本文讨论了一种优化框架，该框架将供需侧管理与对高能耗低温空气分离过程的应用相集成，该过程配备了一个内部发电系统，该系统包括多个可再生和确定性电源以及一个储能系统。拟议的框架整合了发电和购买决策以及空分设备（ASP）的生产复杂性。已显示出所提出的集成框架提供的最佳发电时间表和最佳生产时间表可以最大程度地降低运行所需的总能源成本，并满足低温ASP的生产要求。还进行了经济分析，以研究在ASP中包含内部可再生资源发电和存储系统的经济可行性。已显示出所提出的集成框架提供的最佳发电时间表和最佳生产时间表可以最大程度地降低运行所需的总能源成本，并满足低温ASP的生产要求。还进行了经济分析，以研究在ASP中包含内部可再生资源发电和存储系统的经济可行性。已显示出所提出的集成框架提供的最佳发电时间表和最佳生产时间表可以最大程度地降低运行所需的总能源成本，并满足低温ASP的生产要求。还进行了经济分析，以研究在ASP中包含内部可再生资源发电和存储系统的经济可行性。
