对于含多类型混合储能系统的运行优化,通常将所有设备等效为一个整体,并未考虑各储能系统的运行特性差异等因素,最终导致设备利用率低,经济运行能力差。为此,首先以最大可再生能源消纳以及最小电网交换电量为目标,构建了优化函数模型。其次,考虑到多类型储能系统在充放电动态特性、运行成本特征以及SOC设定等方面差异,提出了一种结合能量型储能SOC一致性约束的双层解耦式运行优化方法,以适应分布式能源系统中的多类型储能协同运行。最后,以某个在建的分布式可再生能源系统工业示范园区数据为基础,对所提方法进行了算例验证与分析。结果证明,所提方法在保证分布式能源系统内多个能量型储能系统充放电同步性的同时,能够对具有相同运行特性的储能系统进行聚类,有效了降低计算复杂性,完成多类型储能协调与优化,并最终促进分布式能源系统的新能源消纳。

Three novel dithienylethenes modified by bifluoroboron β-diketonate fragments have been successfully developed. Upon blue light irradiation, they reached photostationary state within 2-5 s, as well as 100% conversion ratio and photocyclization quantum yield of > 0.70. Such fascinating photochromism were endowed by collaborative role of electron-withdrawing effect of BF_(2)bdk group to reduce HOMO-LUMO electronic gap for the open isomer, together with intramolecular hydrogen bonds and CH-π interactions favoring antiparallel conformation fixation. Moreover, they displayed specific discrimination and photoswitchable bacterial imaging for S. aureus.

钛合金材料因其优异的耐腐蚀性能和机械性能被认为是反应堆的候选结构材料。本文围绕材料服役过程中的辐照损伤机制问题,采用分子动力学(MD)方法研究了金属钛(以α-Ti为例)的辐照级联过程,获得了不同温度(300、500、700和900 K)、不同能量(1、5、10和20 keV)的初级碰撞原子(PKA)沿不同晶格方向([0001]、[1010]和[1100])入射的碰撞过程,并从原子尺度分析了α-Ti在辐照级联过程下的缺陷演化行为及机制。结果表明,随着温度升高,α-Ti级联碰撞过程诱发的峰值点缺陷数明显增加,缺陷复合过程所需时间延长;随着PKA能量增加,整个缺陷演化过程的缺陷数均明显增加,稳定缺陷数也呈增加趋势;而PKA入射方向对级联过程中缺陷演化无明显影响。采用NRT(Norgett-Robinson-Torrens)模型计算获得α-Ti辐照缺陷随PKA能量的变化趋势与MD计算结果一致,级联碰撞后剩余的缺陷数约占NRT预测值的30%。本文从微观角度研究了金属钛的辐照损伤机理,相关计算结果为钛合金在未来核反应堆中的应用提供数据支持,为新型耐辐照材料研发提供理论依据。

Considering the typical acoustic environment of the Arctic, this paper proposes a method based on OASES-Bellhop coupled model to rapidly analyze the multipath structure of the under-ice sound channel. Firstly the proposed model refers to ice plate as stratified elastic media with some roughness. Secondly,it uses the perturbation method and Kirchhoff approximation theory to solve the scattering loss due to the sea ice inhomogeneity. Finally, the model predicts the multipath structure of the under-ice channel through Ray theory. The results of the numerical simulation and experiment indicate that the typical Arctic sound channel presents multipath structures due to the sea ice and seabed in the range of 6 km, *** sea ice reflection paths are stable,with a short multipath spread within 14 ms. The seabed reflection paths have relatively weak strength. The proposed OASES-Bellhop coupled model successfully predicts the amplitude and delay of the multipath structure with small error,which indicates the proposed model is able to analyze and predict the multipath structure of the observed acoustic environment in experiment.

As a part of underwater acoustics, the study and development of Arctic Acoustics is later than underwater acoustics about several hundred years. After World War II, the study of Arctic Acoustics attracts many interests by some developed countries, especially U.S. and pre-Soviet Union. The research works obviously have some kinds of cold war brand. After the Cold War, with the gradual warming trend of Arctic area, the ocean & acoustic environment in Arctic and its adjacent area have been considerably concerned. The 8 countries of Arctic rim organized exclusive "Arctic Council" in 1996. The white paper of "China Arctic Policy"was published in January 26, 2018, the Chinese government declared that China is a close Arctic country, and is the responsible stakeholder of Arctic interests. The new advances in Arctic research works axe introduced in this paper, including the results of scientific survey and studies about Arctic underwater acoustics of Chinese researchers. It is showed that the Arctic underwater acoustical research area is not only parallely copy the topics what traditional underwater acoustics covered, e.g. environment noise,reverberation,and propagation, but also the topics which is specifically based on the Arctic environment. Some of these research fields cannot be included in the traditional shallow water, deep water acoustics, e.g. the ice-water interface feature, ice covered semi-acoustic channel effect, the communication and navigation of UUV in the condition of under ice, and the adaptation of sonar technique, equipment in the ice-covered environment, etc.

The growth of γ-In_(2)Se_(3) thin films on mica by molecular beam epitaxy is studied. Single-crystalline γ-In_(2)Se_(3) is achieved at a relatively low growth temperature. An ultrathin β-In_(2)Se_(3) buffer layer is observed to nucleate and grow through a process of self-organization at initial deposition, which facilitates subsequent monolithic epitaxy of single-crystallineγ-In_(2)Se_(3) at low temperature. Strong room-temperature photoluminescence and moderate optoelectronic response are observed in the achieved γ-In_(2)Se_(3) thin films.
