发电企业作为发电环节的主体具备高碳排放的特征,准确预估其在不同情景下的碳排放量有助于“双碳”目标的实现。目前碳排放量的预估聚焦于国家、部门、行业尺度,鲜少涉及企业尺度的研究。以湖北能源集团为例,基于皮尔逊相关性分析识别火力发电量的影响因素,通过神经网络、决策树、支持向量机(线性核函数、多项式核函数、径向基函数、Sigmoid核函数)、装袋算法、随机森林、线性回归、逐步回归算法分别构建火力发电量预测模型,并依据多种评价指标优选模型。随后以火力发电量和碳排放强度为边界条件,通过抽水蓄能发电、水电站低成本电解水制氢储能来削减企业的火力发电量,通过碳捕捉和碳封存技术来降低企业的碳排放强度。基于削减火力发电量和降低碳排放强度设定“结构减排方案”、“技术减排方案”、“综合减排方案”,推演各情景下的碳排放量。研究结果表明:利用线性回归、逐步回归模型预估火力发电量的效果良好;2030年“结构减排方案”“技术减排方案”“综合减排方案”下碳排放量分别为1648.89万~1934.07万t、1778.07万~1820.94万t、1345.75万~1571.77万t,2050年“结构减排方案”“技术减排方案”“综合减排方案”下碳排放量分别为0~1117.79万t、615.43万~649.70万t、0~299.20万t。本文提出的研究思路和方法可为企业尺度的碳排放量预估提供参考。

The series-approach and the asymptotic-approach are usually used to solve thecomplex variable equation of the toroidal shells under axial symmetric *** is known,theconvergence of the series-solution is good only for small values of μ=(12(1-v2)1/2a2/(r0h).Onthe other hand,the convergence of the asymptotic solution is good only for large values of μ.Inthis paper,based on an earlier work,a new approach which may be called the approximated-asymptotic solution has been developed and it is valid for both small and large values of μ.It isshown that the results of the approximated-asymptotic solution for toroidal shell with μ=0.5coincide very well with those of the series-solution,while the results of the asymptotic solutionfor this value of μ are not as good,and the results of the approximated-asymptotic solution for μ=15 agree with those of the asymptotic solution.

自然杀伤细胞家族2成员D受体-配体轴在血液瘤中的作用研究进展

第25届中国控制与决策会议

作者： zhenhui wu Huawen YE Weihua GUI Chunhua YANG School of Information Science and Engineering Central South University

ISBN: (纸本)9781467355339

This paper investigates the decentralized stabilization of large scale feedforward nonlinear systems via saturated delayed feedback. A class of saturated delayed controllers is first proposed for the single-input feedforward nonlinear systems: an appropriate normal form rather than the homogeneous property of feedforward systems is depended on, and a small parameter contained in the normal form is assigned into the control law. By tuning the small parameter, the control design allows an arbitrarily large input delay. This scheme is then extended to the setting of decentralized feedforward nonlinear systems. The effectiveness of the suggested algorithm is verified by simulations.

关键词： Decentralized stabilization saturated control time delays feedforward systems nonlinear systems.
