An optimal design approach for a modular production system (MPS) for producing renewable methanol is proposed, aming at mitigating carbon dioxide emissions from coal-fired power plants. A mathematical programming model is established to optimize the capacity configuration and material/energy scheduling scheme of the MPS. The coal-fired power plant serves as the variable carbon source, whereas the wind farm provides the fluctuating renewable energy supply. The optimal design parameters and scheduling strategies for the MPS are determined by solving the proposed model. Two scenarios are considered, i.e. one involving sole energy supply fluctuations, and another one encompassing fluctuations in both energy and carbon supplies. These scenarios are analyzed to understand their effects on the design and operational performances of the MPS. The influence of wind power prices on the total annual cost of the MPS is also examined to identify the optimal conditions for deploying the proposed system.

可再生甲醇模块化生产系统优化设计，以减少燃煤电厂的二氧化碳排放


提出了一种用于生产可再生甲醇的模块化生产系统 （MPS） 的最佳设计方法，旨在减少燃煤电厂的二氧化碳排放。建立数学规划模型，优化 MPS 的容量配置和物能调度方案。燃煤发电厂是可变碳源，而风电场则提供波动的可再生能源供应。通过求解所提出的模型来确定 MPS 的最优设计参数和调度策略。考虑了两种情景，即一种涉及单独的能源供应波动，另一种包括能源和碳供应的波动。分析这些情景以了解它们对 MPS 的设计和运行性能的影响。还研究了风电价格对 MPS 年度总成本的影响，以确定部署拟议系统的最佳条件。
