This paper proposes an evolutionary game-theoretic model of massive distributed renewable energy deployment in order to shed light on the self-organization sustainable developments of renewable energies in distribution networks towards low-carbon targets. Since neighboring buses can interact in terms of energy exchanges, the return matrices of individual buses in the evolutionary game are established based on profiles of loads and renewable energy generation. More specifically, an evolutionary strategy is proposed based on the return matrices for individual buses to determine whether or not to deploy renewable energies in the next round of the game. Then, a dynamic model is derived for analyzing the renewable energy penetration rate in the distribution network throughout the multi-round evolutionary game. In theory, this model can reveal the self-organization process of renewable energy deployment in the distribution network. With this model, the distribution network operator would be aided in designing the incentives for buses deploying renewable energies toward a pre-defined low-carbon target. Numerical results on an actual 141-bus system and a synthetic 2000-bus system have demonstrated the validity and efficiency of the proposed model.

金属屋面广泛应用于各类大跨空间结构,但是风灾事故频发,抗风承载力严重不足。为提高金属屋面系统的抗风揭性能,保证其在强风作用下的安全稳定性,对长春龙嘉国际机场二期屋面工程设计提出的新型金属屋面系统进行了抗风承载力试验研究。采用新型金属屋面系统与直立锁边金属屋面系统抗风承载力对比试验,对两者抗风承载力以及极限风压下的破坏变形进行对比分析。利用ABAQUS软件建立了有限元实体模型,模拟其破坏全过程的位移变形状态。研究结果表明:新型金属屋面系统的抗风承载力较直立锁边金属屋面系统的抗风承载力提高了2.5倍,且极限风压下的最大变形量减小了10%。有限元分析结果与试验结果吻合良好,可验证有限元模型的有效性。研究成果可为金属屋面系统技术在实际工程中的应用提供参考。

避免重构中生成不可行解是解决配电网快速重构问题的关键。现有方法往往只考虑拓扑结构而未考虑节点负荷的波动,没有规避重构中生成大量劣解,即满足拓扑约束但适应度值很高的解,重构计算耗时依然较长且存在搜索不到最优解或次优解的可能。针对上述缺陷,提出一种基于自适应负荷调整网络矩阵的配电网重构方法。在基本环矩阵的基础上,根据各节点实时负荷的大小,通过计算功率矩并进行支路组校验生成自适应负荷调整网络矩阵,排除了大量劣解,缩小了可行解范围,提升了可行解空间的质量,不仅加快了重构速度,而且更容易搜索到最优解。针对重构模型对烟花算法的爆炸算子、变异算子、选择策略进行改进,使之能快速收敛,并采用改进烟花算法进行求解。通过对33节点系统和119节点系统分别进行降损重构和故障后重构的算例仿真,验证了所提方法的有效性。

Fe-Ce-OH@AR14 was obtained via the adsorption of acid red 14(AR14) on Fe-Ce-OH prepared by the codeposition of cerium nitrate hexahydrate,ferric nitrate nonahydrate,and ammonia,and then Fe-Ce-O@C with high photocatalyic efficiency was synthesized by the calcination of Fe-Ce-OH@AR14 in N_(2).For comparison,Fe-Ce-O was also prepared by the calcination of Fe-Ce-OH in N_(2).The obtained materials were characte rized by X-ray diffraction(XRD),Raman,X-ray photoelectron spectroscopy(XPS),Fourier transform infrared spectroscopy(FT-IR),scanning electron miscroscopy(SEM),photoluminescence(PL),ultraviolet-visible diffuse reflectance spectroscopy(UV-vis) techniques and the results show that the band gap of CeO_(2) can be greatly reduced by doping of Fe^(3+),and that loading carbon from the decomposition of AR14 can prolong carrier life,improve the intensity of visible light absorption,and enhance the concentration of oxygen *** photocatalytic results using AR14 as probe molecule illustrate that using 1% ferric nitrate nonahydrate(the mass percentage of ferric nitrate nonahydrate to cerium nitrate hexahydrate) as dopant and 25 mL of 0.01 mmol/L AR14 as loading carbon resource is helpful for the photocatalytic efficiency of CeO_(2).

Random lasing was experimentally investigated in pyrromethene 597-doped strongly disordered chiral liquid crystals (CLCs) composed of the nematic liquid crystal SLC1717 and the chiral agent CB15. The concentration of the chiral agent tuned the bandgap, and disordered CLC microdomains were achieved by fast quenching of the mixture from the isotropic to the cholesteric phase. Random lasing and band edge lasing were observed synchronously, and their behavior changed with the spectral location of the bandgap. The emission band for band edge lasing shifted with the change of the bandgap, while the emission band for random lasing remained practically constant. The results show that the threshold for random lasing sharply decreases if the CLC selective reflection band overlaps with the fluorescence peak of the dye molecules and if the band edge coincides at the same time with the excitation wavelength.
