The increasing penetration of renewable energy sources (RESs) brings great challenges to the frequency security power systems. traditional frequency-constrained unit commitment (FCUC) analyzes by simplifying average system and ignoring numerous induction machines (IMs) in load, which may underestimate risk increase operational cost. In this paper, we consider a multi-area response (MAFR) model capture dynamics scheduling problem, regional inertia IM load are modeled with high-dimension...
Abstract The development of materials integrated with ultrasmall multi‐metal nanoparticles (UMMNs) and mesoporous zeolite is a considerable challenge in chemistry science. We designed trifunctional surfactant, which the pyridyl benzimidazole hydrophobic tail generates mesopores through π–π stacking; diquaternary ammonium hydrophilic headgroup direct formation MFI sheets nitrogen atoms heterocyclic rings coordinate various metal ions to form UMMNs confined matrix after calcination reduction....
Thirteen raw coal samples from Qinshui coalfield were prepared to produce coal-based graphene, and the coal, graphite, graphene sheets (GS) characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy with energy dispersive spectrometer (SEM-EDS), high-resolution transmission (HRTEM). The results show that graphitization degree of graphite is positively linearly correlated reflectance has a low positive correlation content inertinite, vitrinite in coal....
Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, as a dealuminating agent, could interact with the framework Al species in Al-rich Beta (Si/Al = 4.3) under mild condition, producing natroalunite phase and dealuminated higher Si/Al ratios of 7.6–12.
The challenge of how to effectively treat minerals in coal before synthetic graphitization is a practical problem. It unrealistic remove completely via physical or chemical methods. So, it essential clarify the role coal. Based on complex mineral composition, mixture samples consisting and are used obtain effect type content closely associated with type, as well rank. As lower-rank anthracite, quartz, kaolinite, calcite have inhibitor for yields defect degrees corresponding after derived...
Coal-based graphene sheets (GS) and coal-based quantum dots (GQDs) are usually prepared separately. In this paper, symbiosis of GS GQDs was successfully with our proposed preparation method by using three raw coals different reflectance (collected from Qinshui coalfield, Shanxi Province) as carbon sources. The results showed that can exist stably in the distributed layers, freely between layers GS. average number (Nave) is about 7 interlayer spacing (d002) 0.3887 nm. diameter 4.255 nm...
The pore structure of organic matter (OM) is affected by the maturity and type OM, these exert an important control on development OM pores. However, it often challenging to distinguish between autochthonous secondary OM. In this study, different types were distinguished means morphology form its occurrence under scanning electron microscopy (SEM) observation. Pyrolyzed samples used obtain structures from a lacustrine shale high over mature stages. SEM observations indicated that porous,...

Methanol-to-olefins (MTO) technology presently serves as a key to convert coal or natural gas valuable hydrocarbons, in particular lower olefins.
Internet of Electric Things (IoET) based on edge computing mode has advantages in functionality, communication efficiency and construction cost. However, the incompleteness relevant security protocols restricts their application smart grids. Therefore, we propose a lightweight three-layer device identity mutual authentication key agreement protocol suitable for IoET with two-hops architecture. The simulation results formal analysis automated toolset AVISPA attacks show that this can meet...
Abstract The utilization of high‐sulfur coal, especially high‐organic has always been a difficult hot spot in the energy field. To study influence sulfur coal on coal‐based graphite products, series samples with different content and degrees coalification were collected for proximate analysis, ultimate species analysis. structural characteristics products analyzed by X‐ray diffraction (XRD). relationships between yield (Y), graphitization degree (G), cell diameter (L ), stacking height c )...
