| 3 | Optimal guidance strategy for flexible load based on hybrid direct load control and time of use显示文摘The time-of-use(TOU)strategy can effectively improve the energy consumption mode of customers,reduce the peak-valley difference of load curve,and optimize the allocation of energy resources.This study presents an Optimal guidance mechanism of the flexible load based on strategies of direct load control and time-of-use.First,this study proposes a period partitioning model,which is based on a moving boundary technique with constraint factors,and the Dunn Validity Index(DVI)is used as the objective to solve the period partitioning.Second,a control strategy for the curtailable flexible load is investigated,and a TOU strategy is utilized for further modifying load curve.Third,a price demand response strategy for adjusting transferable load is proposed in this paper.Finally,through the case study analysis of typical daily flexible load curve,the efficiency and correctness of the proposed method and model are validated and proved. | Siyang Liu Yuan Gao Hejun Yang Xinghua Xie Yinghao Ma | 2023 | Global Energy Interconnection2023，6，3： | 1 |

| 5 | Efficient removal of Cr(Ⅵ)and Pb(Ⅱ)from aqueous solution by magnetic nitrogen-doped carbon显示文摘The magnetic nitrogen-doped carbon (MNC) was prepared from polypyrrole by a simple high temperature calcination process in this paper. The structure and properties of MNC were analyzed by scanning electron microscope, Fourier transform infrared spectroscopy, X-ray diffraction, Brunner-Emmet-Teller, vibrating sample magnetometer, and X-ray photoelectron spectroscopy. The capacity of MNC to adsorb Cr(Ⅵ) and Pb(Ⅱ) was evaluated. The effects of the initial pH, dosage, concentration and temperature on the adsorption capacity of MNC were measured. MNC had a large specific surface area and a special porous structure. Its nitrogen and carbon sources were rich, and the ratio of carbon to nitrogen was fixed. The maximum Cr(Ⅵ)-adsorption capacity and maximum Pb(Ⅱ) adsorption capacity of MNC could reach 456.63 and 507.13 mg·g^(−1) at 318 K, respectively. The pseudo-second-order model was used to describe the adsorption kinetics of MNC, and the Freundlich model was employed to discuss its isotherms. The adsorption process was affected by the electrostatic force, the reducing reaction, pores and chelation. The results of this study suggest that MNC is a material with superior performance, and is very easily regenerated, reused, and separated in the adsorption process. | Wanyue Liu Xiaoqin Liu Jinming Chang Feng Jiang Shishi Pang Hejun Gao Yunwen Liao Sheng Yu | 2021 | Frontiers of Chemical Science and Engineering2021，15，5： | 0 |
