Multi-port solid-state transformer (SST) characterized by high scalability is expected to be widely used in AC/DC hybrid microgrid. However, the DC bus voltage deviation and dynamic response speed are two key issues its application. Therefore, a model predictive direct power control (MPDPC) of three-port SST (TPSST) proposed. Compared with traditional PI-based method, oscillation inhibited, steady-state performance improved MPDPC method. Moreover, path incorporated into system order...
Photovoltaic power generation relies on electronics and therefore does not have natural inertia damping characteristics. In order to make the capacitance of medium time scale participate in grid frequency response without adding additional equipment, this paper takes grid-connected photovoltaic system based DC voltage droop control as research object, establishes static synchronous generator (SSG) model system. The is used analyze main parameters affecting inertia, synchronization...
The heat exchanger plays a key role in the S-CO2 power cycle of generation systems based on waste and has large impact their cost control compactness. In this paper, we take channel shape microchannel as research object combine orthogonal tests numerical simulation, taking cross-section length/short-axis ratio, volume ratio filling rate independent variables, to numerically study multi-channel thermal–fluid–solid coupling explore effects different ratios, ratios rates thermal hydraulic...
In this paper, a new method of fault location based on one-terminal transient voltage traveling waves is put forward. The process caused by breaker tripping contains the information about distance. By measuring period induced tripping, distance can be obtained. Before giving principle, model analyzed. elements to affect accuracy have been discussed. Finally, was verified EMTDC simulations.
Due to its intermittent nature, integrating large quantities of wind power in systems has serious impacts on system operation. Wind increases the load variation and reserve requirements for contingencies. Utilities are especially concerned about availability during peak demand time. Conventional generation can obtain capacity credit because they produce “firm” As is it normally given zero or small credit. In this paper, multiple farms distributed Wyoming analyzed based actual data....
Abstract In view of the lack automation current material handling measures, based on a brief introduction to structure robot, this article mainly studies trajectory planning and control manipulator. First, basic manipulator is simplified, joint coordinate system robot arm established by Denavit-Hartenberg (D-H) method, then kinematics forward inverse solution model obtained analysis. The fifth-order polynomial interpolation algorithm used plan space rotating joint, Matlab applied perform...
It is well-known that the refocusing flip angles (FAs) of SPACE sequence can be optimized to generate different image contrasts, such as T1-weighted or T2-weighted. However, existing variable FA scheme unsuitable for CEST imaging whose utmost aim increase SNR during signal readout instead enforcing contrast. Here, we derived a model describe signal-to-noise ratio (SNR) sequence, and maximized by varying angles. Compared original constant protocol, yielded both resolution improvement.
<h3>Background</h3> Magrolimab is a monoclonal IgG4 antibody that binds to CD47, blocking the CD47-SIRPα checkpoint interaction. Previous clinical trials demonstrated on-target anemia mitigated by administrating low 'priming' dose of antibody.<sup>1–3</sup> While CD47 critical for RBC homeostasis and findings suggest priming affords protection, mechanism this effect unknown. Here we use human CD47/SIRPα double knock-in (DKI) preclinical model elucidate mechanisms magrolimab-induced recovery....
When solving partial differential equations (PDEs), classical numerical methods often require fine mesh grids and small time stepping to meet stability, consistency, convergence conditions, leading high computational cost. Recently, machine learning has been increasingly utilized solve PDE problems, but they encounter challenges related interpretability, generalizability, strong dependency on rich labeled data. Hence, we introduce a new PDE-Preserved Coarse Correction Network (P$^2$C$^2$Net)...
Superhydrophobic surfaces based on electrospun fibrous structures exhibit advantages of additive manufacturing and enable the passage gases. Compared to randomly deposited fibers, directionally aligned fibers improve control surface wetting by a specified fiber orientation predictable liquid–fiber contact interface. In this article, we create superhydrophobicity with adjustable adhesion understanding droplet behavior fibers. Directionally polystyrene different diameters interfiber distances...
