摘　　要：为有效解决高耗能电解铝企业高污染、高排放问题并降低其工业电网内弃风、弃光率,提出一种面向风光消纳的并网型绿电铝评价企业优化运行策略。分析并网型绿电铝评价企业运营模式和基于生产过程的电解铝负荷功率特性,在此基础上综合考虑工业电网电力电量平衡约束、电解铝负荷约束、自备风光火机组约束和外部电网交互约束,以综合用电成本最小为优化目标,构建了并网型绿电铝评价企业优化运行模型;通过引入4组反映电解铝负荷调节特性的0-1辅助变量,能够精确地描述电解铝负荷不能即时调节和频繁调节的特性,实现其调节性能对风光出力不确定性适应能力的解析表达,并将优化模型表达为线性0-1混合整数规划模型。通过算例分析,验证了所提模型方法的有效性,以及并网型绿电铝评价企业在大幅降低企业碳排放成本和提高风光发电利用率方面的优势。Propose an optimized operation strategy for grid-connected green power aluminum enterprises aimed at addressing the issues of high pollution and emissions in high-energy-consuming aluminum electrolysis companies while reducing the abandoned wind and solar energy within their industrial power grids.Analyze the operational model of grid-connected green power aluminum enterprises and the power characteristics of aluminum electrolysis load based on the production process.On this basis,comprehensively consider constraints such as industrial power grid power balance,aluminum electrolysis load,self-owned wind and solar units,and external grid interaction.With the optimization goal of minimizing comprehensive electricity costs,construct an optimization operation model for grid-connected green power aluminum enterprises.Introduce four sets of 0-1 auxiliary variables reflecting the characteristics of aluminum electrolysis load regulation,accurately describing the inability for immediate and frequent adjustments,enabling the analytical expression of its regulatory performance's adaptability to the uncertainty of wind and solar output.Express the optimization model as a linear 0-1 mixed-integer programming model.Through case analysis,validate the effectiveness of the proposed model and the advantages of grid-connected green aluminum enterprises in significantly reducing carbon emission costs and improving the utilization efficiency of wind and solar power generation.
