The development of high activity electrocatalysts that can operate stably at current density for the large-scale production hydrogen is an important but challenging task.
The hydrolysis of S ion FeNi 2 4 can promote the in-situ formation ultrathin amorphous NiFe–LDH grown in situ on crystalline , which not only improve activity but also significantly enhance stability for oxygen evolution reaction.
Promoting the reconstruction of electrocatalysts during oxygen evolution reaction (OER) is generally regarded as a promising strategy for enhanced activity. F anions with strong electronegativity are predicted to enhance this transformation. Herein, fluorine-anion doping route proposed convert well-latticed NiMoO4@MNF amorphous F-NiMoO4@MNF by facile and versatile molten salt strategy. The well-defined nanorod arrays guarantee abundant exposed active sites, rapid mass transfer, fast gas...
Abstract The large application of renewable energy generation (REG) has increased the risk cascading failures in power system. At same time REG also provides possibility new approaches for suppression such failures. However, capacity and position synchronous generator (SG) involved regulation limit speed (PRS) to overload line which is main cause failures, while PRS SG related shedding power. SGs have difficulty achieving effective cooperation under constraints system balance. Particularly,...
Receiving-end grid fault may induce DC overvoltage in the high voltage direct current-based source converter (VSC-HVDC). The existing control method has a fixed initiation threshold, and active power regulation of sending-end (SEC) receiving-end (REC) are independent, which is prone to non-essential activation SEC energy-dissipating device(EDD). By quantifying capability REC under AC current reactive constraints, concept maximum permissible duration (MPD) avoid when regulating alone its...
Fe chelated with tannic acid is precisely anchored to ultrathin Co hydroxides (TF@Co(OH) 2 - t ) through a new anodic interfacial coordination assembly.
Crystal–amorphous NiO/MoO 2 with a coupled high-density and well-dispersed heterojunction has been designed to tailor the charge distribution lower reaction energy barrier for HER.
The utilization of direct-drive permanent magnet synchronous generator-based wind turbine (DPMWT) is prevalent in mitigating unbalanced power during fault process. However, sudden variations the magnitude and phase angle grid voltage faults may result phase-locked loop transient response (PLTR) DPMWT. PLTR changes output characteristics DPMWT through converter control loop. This alteration incorporates dynamic errors presents potential hazards to frequency system. Therefore, error resulting...
Line-commuted converter-based high-voltage direct current (LCC-HVDC) has undergone extensive development in power systems. Commutation failure (CF) LCC-HVDC poses a considerable threat to the safe and stable operation of The coupling electrical quantities, including DC current, voltage, AC extinction angle (EA) an inverter station, is critical factor that makes CF difficult suppress effectively. Existing methods adopt preset fixed control parameters single target. demand recovery typically...
The accumulation of imbalanced power during the fault leads to a rapid rise in DC voltage, which threatens security voltage source converter-based high direct current (VSC-HVDC). Existing studies use dynamic braking resistor, regulation sending-end grid, or reactive control avoid overvoltage support grid voltage. However, interaction between active and relationship receiving-end converter (REC) duration are ignored, resistor could be triggered unnecessarily, not supported effectively. An...
