This paper proposes a distributed robust optimal dispatch model to enhance information security and interaction among the operators in the regional integrated energy system(RIES).Our model regards the distribution network and each energy hub(EH)as independent operators and employs robust optimization to improve operational security caused by wind and photovoltaic(PV)power output uncertainties,with only deterministic information exchanged across *** paper also adopts the alternating direction method of multipliers(ADMM)algorithm to facilitate secure information interaction among multiple RIES operators,maximizing the benefit for each ***,the traditional ADMM algorithm with fixed step size is modified to be adaptive,addressing issues of redundant interactions caused by suboptimal initial step size settings.A case study validates the effectiveness of the proposed model,demonstrating the superiority of the ADMM algorithm with adaptive step size and the economic benefits of the distributed robust optimal dispatch model over the distributed stochastic optimal dispatch model.

Four kinds of cryptomelane-type octahedral molecular sieve(OMS)-2-X(the X represents the molar ratio of KMnO4/MnAc2) were prepared as catalytic materials for ozone decomposition through a one-step hydrothermal reaction of KMnO4 and MnAc2, by changing their molar ratios. These samples were characterized by N2 adsorption–desorption, X-ray di raction(XRD), transmission electron microscopy(TEM), scanning electron microscopy(SEM), temperature programmed reduction by H2(H2-TPR) and X-ray photoelectron spectroscopy(XPS). Among them, the OMS-2-0.7 sample showed the best O3 conversion of 92% under high relative humidity(RH) of 90% and gas hourly space velocity of 585,000 h-1. This was accordingly thought as a possible way for purifying ozone-containing waste gases under high RH atmospheres. The e ciency of ozone decomposition of the prepared OMS-2-X sample was found to be related to specific surface area, particle size, surface oxygen vacancies, and Mn3+ cation amounts. The one-step hydrothermal synthesis was shown to be a simple method to prepare the considerably active OMS-2 solids for ozone decomposition.

目前Fe_3O_4纳米颗粒由于其优秀的物理、化学性能及特有的磁性能,在吸附剂领域有着很好的应用前景。为此,使用共沉淀法制备Fe_3O_4纳米颗粒,以3-氨丙基三乙氧硅烷(APTES)为修饰剂,根据甲酸钠与乙酸银的特异性反应,制备出磁性Fe_3O_4-Ag复合纳米颗粒吸附剂。通过固定床吸附实验考察吸附剂对模拟烟气中汞的脱除能力,讨论其对汞的脱除机理。研究结果表明:磁性Fe_3O_4-Ag复合纳米颗粒吸附剂可脱除90%以上模拟烟气中的汞,且具有很好的抗酸性气体性能。包裹Ag提高了纳米颗粒的稳定性,提高了纳米颗粒的比表面积和总孔容积,且Ag可以与元素汞发生汞齐反应。温度的提高会抑制吸附剂对汞的吸附及汞齐反应的进行,降低吸附剂的脱汞能力。吸附剂对汞的脱除机理为物理吸附为主,且高温下被吸附的汞会从吸附剂中脱附。吸附剂还具有很好的再生性能,重复脱附吸附多次后仍保持很好的脱汞能力。

为探讨酶解鱿鱼内脏浆滤过液(HSVP-A)和酶解鱿鱼内脏浆截留物(HSVP-B)对黄颡鱼生长的影响,试验以初始体重为(14.21±0.09)g的黄颡鱼幼鱼为试验对象,以30%、15%和0秘鲁超级蒸汽鱼粉(FM、HFM和NFM组)为对照,在15%鱼粉日粮和无鱼粉日粮中按0.5%、1.5%、2.5%和3.5%的梯度添加HSVP-A和HSVP-B,共设计19组等氮等脂日粮,每组3个重复,每个重复40尾,养殖8周后采样。结果表明:(1)与NFM组相比,NB-4组的成活率显著降低(P0.05);(2)与FM组相比,HA-2和NB-4组的特定生长率(SGR)升高,差异不显著(P>0.05);(3)以NFM组为对照,NB-4组的谷丙转氨酸(AST)和谷草转氨酸(ALT)含量显著降低(P<0.05),NB-4组的低密度脂蛋白(LDL)含量显著增加(P<0.05);(4)HA-2组以HFM组为对照,NB-4组以NFM组为对照,两个试验组的总抗氧化能力(T-AOC)升高,丙二醛(MDA)含量降低,差异显著(P<0.05),并且HA-2组的超氧化物歧化酶(SOD)活性显著升高(P<0.05)。研究表明在日粮动物蛋白总量相同的基础上,15%鱼粉日粮中添加1.5%HSVP-A以及无鱼粉日粮中添加3.5%HSVP-B对黄颡鱼的生长性能最好,与30%鱼粉组表现出一定的等效关系。
