混合遗传算法在气田产量构成优化模型中的应用

open access: yes, 2006
在气田开发规划产量构成优化模型的基础上,引入一种单目标模型的改进遗传算法,把无约束优化中的直接解法Powell方法作为一个与选择、交叉和变异平行的算子嵌入到基本遗传算法中;并利用了一种新的退火精确罚函数法处理约束条件,运用MATLAB6.0编写算法程序,选取开发规划产量构成优化模型中的定成本产量最大模型,实例分析该算法在气田开发规划产量构成优化模型中的具体应用 ...

提升风电消纳水平的电力系统灵活性措施经济性评估方法研究 [PDF]

open access: yes全球能源互联网, 2018
近年来,中国风电并网容量不断增大,出现了严重的弃风现象,随着各类技术可行的灵活性措施提出,亟需研究经济合理的措施组合以降低弃风量。为此,提出一种提升风电消纳能力的电力系统灵活性措施的经济性评估方法。首先,构建基于成本效益的经济性评价指标,即减少风电弃风量的单位成本,以量化各类灵活性措施对提高电网风电消纳能力的效果;然后,采用时序生产模拟模型量化分析系统的年度弃风总量,生产模拟模型考虑常规电源、风电及负荷,以小时为仿真粒度进行机组组合和经济调度;最后,构建了灵活性措施的年化成本模型 ...

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature
