A scalable synthesis method for foldable carbon nanotube-coated cobalt particle electrodes on cloth was established through metal-organic framework gel pyrolysis. These exhibit excellent bifunctional catalytic activity and enhanced durability, making them highly promising commercial zinc-air battery applications.
This paper presents a particle swarm optimization (PSO) method to deal with reactive power problem in province system China. The objective the is minimize real losses whilst maintaining acceptable voltage profiles. Particle optimization, new evolutionary computation method, relieves derivative assumptions of function and deals continuous discrete variables conveniently. effects PSO parameters, such as inertia weight, learning factors population size have been empirically studied. successful...
In this work, the dissimilar joint of AA7003-T4 and 6060-T4 alloy has been produced by friction stir welding (FSW). The microstructure was examined optical microscope (OM), electron back scattered diffraction (EBSD), transmission microscopy (TEM), mechanical properties were investigated. It is demonstrated that sound can be through FSW. nugget; precipitations dissolve into matrix η' reprecipitate subsequently; elongated aluminum grains are replaced fine equiaxed due to dynamic...
Abstract The maturation of male and female gametophytes together with its impact on plant sexual reproduction has not received much attention, the molecular mechanisms underlying process are largely unknown. Here, we show that Arabidopsis DEAD-box RNA helicase 29 (RH29) is critical for functional both gametophytes. Homozygous rh29 mutants could be obtained, heterozygous mutant plants were semi-sterile. Progression cell cycle in was delayed. Delayed pollination experiments showed underwent...
This paper combines the theory of decomposition and coordination with improved tabu search (TS) technique applies them to reactive power planning in area systems. Based on coordination, complex problem is decomposed into several sub-problems under different load conditions. Each sub-problem solved by which a heuristic optimal characterized avoiding local solutions high probability. Sensitivity analysis expert knowledge are used aid initial solution generation improve process. Compared...
Compaction quality control in filling construction is of great significance to the stability and durability face rockfill dam. The conventional method mainly relies on manual process inspection for a limited number test holes, which cannot meet high requirements modern mechanized schedule anymore, with increasing scale dams. There an urgent need propose new dams during entire compaction process. In this paper, supervisory system based GNSS (Global Navigation Satellite System) technology,...
This paper proposes a model and algorithm of coordinated voltage optimal control (CVOC) between active distribution network (ADN) microgrids considering the integration PVs. The CVOC is implemented via decomposition coordination method. In ADN level, each microgrid taken as an equivalent load at point common coupling (PCC). Meanwhile, in treated power supply source PCC. Consequently, optimization problem overall split into series sub-problems microgrids. are calculated alternately based on...
Abstract Under the background of dual carbon goal and new power system, system becomes more complex diverse, voltage sag events caused by short-circuit faults, overloads, switching operations, large motor starting, distributed generation access are frequent. On other hand, with increasing sensitivity low-voltage distribution network electrical equipment to quality, especially for precision process control using computers, electronics, automation technology, energy generating units, electric...
Continuous displacement of conventional power plants by wind turbines significantly weakens the dynamic reactive support ability grid. To correct nonviable or unstable voltages and avoid an imminent long-term voltage instability, this paper proposes a decentralized robust emergency control strategy system with large-scale integrated via source converter based multi-terminal direct current (VSC-MTDC). Firstly, partition approach combining electrical distance network structure is proposed. The...
The urban agglomerations in the middle reaches of Yangtze River occupy an important position regional development pattern China. Grasping spatial and temporal accurately is great significance for planning agglomerations. This paper selects DMSP/OLS nighttime stable lighting data from year 1993 to 2011, extracts annual land area 33 cities city group based on threshold value, calculates total light intensity value growth rate each city. By using center gravity model statistical data, distances...
In this study, the (Fe,Cr)7C3/Fe dense ceramic layer was produced by in situ synthesis method with subsequent heat treatment. According to results of thermal analysis, as-cast specimen subjected treatment at 1186, 1208, 1230 °C for 1–5 h argon atmosphere respectively. The microstructures compound region were characterized X-ray diffraction (XRD) and scanning electron microscopy (SEM), kinetics (Fe,Cr)7C3 analyzed. show that a-Fe are predominant crystalline phases composite obtained....
The increasing proportion of renewable energy generation resources in a power grid, has resulted the capacity reduction traditional synchronous units significantly, and turn insufficient regulation capability for reactive/voltage control grid. It is particularly case grid where mainly supplied by LCC-HVDC (Line Commutated Converter based High Voltage Direct Current) links. distributed (DERs) can be alternative reserves voltage such kind In this paper, steady-state voltage-dependent models...
