Research on Energy Efficiency Optimization Algorithm for Copper Flash Smelting Process Based on Data-driven [PDF]
, 2016 铜闪速熔炼工序具有多变量、非线性、大时滞、强耦合、生产波动大的特点，传统的基于机理模型的优化控制系统很难适应多变的运行条件，预测结果偏差较大，影响最终的控制效果。随着计算机技术的发展，复杂工业过程中积累了大量生产数据，为我们从人工智能的角度进行建模与优化控制提供了数据基础。 本论文以某大型闪速炼铜企业的闪速熔炼生产过程为研究对象。为了实现铜闪速熔炼工序中的节能减耗，本文提出了一种满足三大工艺指标（冰铜品位，冰铜温度，渣中铁硅比）约束的能效优化模型：首先 ...

考虑电-气-碳综合交易的跨国电网分散式电力调度—以规划的东北亚跨国电网为例 [PDF]
全球能源互联网, 2019 为了实现跨国电网的有序发展与协调运行，跨国层面的电力交易、天然气交易和碳交易的有机结合十分关键。为此，以电力系统为核心，考虑天然气交易与碳交易的相关耦合因素，建立了跨国电-气-碳综合交易模型。在上述综合交易的框架下，建立了跨国电网的动态电力调度模型，以实现全局效益的最大化。进一步地，为了保护各个国家的工业信息隐私，提出了分散式的跨国电力调度算法，将全局优化问题转化为各个国家的子问题迭代求解，得到满足给定精度的全局最优解。最后，对东北亚跨国电网仿真算例进行测试，分析讨论在不同电-气 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Guangtongxin yanjiu, 2009 文章仿真验证了在差分相移键控（DPSK）解调时,通过调整延时线干涉仪（DLI）两臂的相对延迟来优化自由光谱范围（FSR）,使其大于传输比特率,能够获得比传统1 bit延迟更好的传输性能,并得到了FSR的最优值。优化FSR后的DPSK解调系统对光信噪比（OSNR）灵敏度和色度色散容限范围均有改善,对偏振模色散（PMD）的容忍度没有明显提高。
