An improved nondominated sorting genetic algorithm-II (INSGA-II) has been proposed for optimal planning of multiple distributed generation (DG) units in this paper. First, multiobjective functions that take minimum line loss, voltage deviation, and maximal stability margin into consideration have formed. Then, using the INSGA-II algorithm to solve problem described detail. The strategy novel truncation based on hierarchical agglomerative clustering are utilized keep diversity population. In...
Abstract The access of large‐scale distributed generation (DG) easily leads to energy imbalance in distribution network. To deal with this issue, paper proposes an optimal schedule method for network considering the participation source‐load‐storage aggregation groups (SAGs). Firstly, system model consisting layer and SAGs is established, objectives constraints each are also given. Secondly, fluctuation on load side, a forecasting based Adaboost integrated convolutional neural networks...
Redesigning heterogeneous catalysts so that they can simultaneously integrate the efficiency and durability under reaction environments with respect to gas fuel production, such as hydrogen (H2), oxygen (O2), or carbon monoxide (CO), has proven challenging. In this work, we report successful template-assisted printing-based assembly of platinum (Pt) nanoparticles (NPs) into striped-pattern (SP) superlattices produce H2. comparison drop-casting flat Pt NPs films, SP lead higher mass...
Abstract Surface enhanced Raman scattering (SERS) has great potential in the early diagnosis of diseases by detecting changes volatile biomarkers exhaled breath, because its high sensitivity, rich chemical molecular fingerprint information, and immunity to humidity. However, two factors limit application SERS: 1) specific enrichment trace target molecules SERS hotspots; 2) stability reproducibility signals multi‐interference environments. In order accurately detect complex breath eliminate...

Under photocatalytic...
A newly developed cathode material, , was synthesized and characterized. X-ray diffraction results identified it as a cubic perovskite structure. Thermogravimetric showed that lattice oxygen loss about 2% in weight between 50 1000°C. Thermal expansion coefficient air argon were extraordinarily high, with slope changes occurring at 382 360°C, respectively. Electrical conductivity values sufficient for application the maximum of 500°C 900°C correspondingly. Both thermal electrical properties...

The objective proposed method is to minimize active power loss system decrease number switching device operations while maintaining within allowable range. Nondispatchable dispatchable are both considered method. To solve mixed...
Point cloud semantic segmentation (PCSS) is crucial for digital twins of high-speed railways. By now, the concerned subjects are confined within interior infrastructures However, surrounding environments also important safe operation. Concerning this issue, a full-range railway scanning scheme based on unmanned-aerial-vehicle-borne LiDAR utilized. massive data volume and distribution imbalance pose great challenges PCSS. To address these issues, novel PCSS framework called 3DGraphSeg...
Virtual synchronous control has been widely studied for the advantages of emulating inertia voltage source converters (VSCs).A constant dc-link is usually assumed in existing literature to estimate transient stability virtual generators (VSGs).However, actual power supply dc-side VSGs limited and different controllers are needed achieve balance between DC side AC side.Addition controller great influence on behavior VSGs, which not investigated by previous research.To fill this gap, paper...

People often associate roughness with difficulty, as a figure of speech. Studies have shown that there is metaphorical connection between the concept rough versus smooth feel and degree difficulty. However, it has not been determined whether tactile experiences influence judgments perceived task difficulty from perspective physical metaphors. This study used Stroop experimental paradigm to investigate effects haptic on perceptual tasks in two experiments. (1) There psychological reality...
