Mobile energy resources (MERs) have been shown to boost DS resilience effectively in recent years. In this paper, we propose a novel idea, the separable mobile storage system (SMESS), as an attempt further extend flexibility of MER applications. "Separable" denotes that carrier and modules are treated independent parts, which allows carry multiple scatter them independently throughout DS. The constraints for scheduling SMESSs involving carriers derived based upon interactive behavior among...

Abstract Structural diversity of biomolecules leads to various supramolecular organizations and asymmetric architectures self‐assemblies with significant piezoelectric response. However, the piezoelectricity biomolecular has not been fully explored relationship between structures remains poorly understood, which hinders development biomaterials. Herein, for first time, vitamin‐based power generation is systematically explored. X‐ray diffraction studies revealed that vitamin molecules can...

In this paper, we investigate the adsorption performances of pristine and Pt-doped HfSSe (Pt-HfSSe) monolayer upon H2S SO2 molecules based on first-principles theory. Results indicate that Pt dopant preferred to be doped Se-surface with formation energy (Ef) −1.06 eV. The Pt-HfSSe has remarkably improved (Ead) SO2, calculated as −0.614 −0.918 eV respectively which are about 2.6 2.9 times than those in counterpart systems. BS DOS analysis reveal sensing mechanism for detection manifest its...

As the integration of renewable energy into regional urban power grid, guaranteeing safety oil-immersed transformers emerges as a top priority. Dissolved gas analysis by nanomaterial-based sensor is workable technique to evaluate operation status transformers. This work purposes Nb-embedded PdSe2 (Nb-PdSe2) monolayer potential upon C2H2 and C2H4, two typical dissolved gases, using first-principles theory. One Se atom pristine substituted one Nb establish Nb-PdSe2 configuration, which...

The blocking of large-capacity HVDC or the tripping AC transmission lines by accident will cause power flow transfer sharply and increase risk cascading faults in AC/DC hybrid grid. Therefore, it is needed to take reasonable safety control measures time interdict spreading accident. In this paper, a post-contingency (PPFC) strategy for grid was proposed. This brings dynamic electrothermal effects conductor into constraints fully excavate short-time overload endurance capability lines,...

The overload degree of a transmission line is represented by currents in traditional protection, which cannot reflect its safety condition accurately. sudden rise current may lead to cascading tripping under protection during power flow transfer system. Therefore, timely and accurate analysis the transient temperature overhead lines, revealing their endurance capability premise ensuring safety, coordination with system controls can effectively eliminate overloading. This paper presents...

Traditional overload protection depends on pre-set values and cannot reflect the current tolerance capability of line. If a line exceeds setting value its protection, then it will be subsequently tripped off cause power flow transferring, which may trigger cascade tripping grid. So is significant importance for to accurately evaluate real-time safety status transmission coordinate with system control eliminate overload. In this article, starting from mechanism analysis conductor heat...

Virtual Synchronous Generator (VSG) technology can be used for increasing inertia of a microgrid especially at islanded operation mode. In current VSG-controlled inverters, the characteristics DC sources are usually ignored, and VSG parameters mostly fixed, leading lower utilization power side along with undesirable frequency fluctuation during large disturbance loads. this paper, multi-parameter adaptive allocation strategy is proposed an consisting parallel photovoltaic (PV)/ Battery-VSGs...

In order to improve the performance of four wheel driver vehicle, structural characteristics inter-axle torque distribution with planetary gear are analyzed, and a dynamic model drive vehicle is established.
