Published: November 2019

Thermoelectric materials, which directly convert heat into electricity based on the Seebeck effects, have long been investigated for use in semiconductor refrigeration or waste heat recovery. Among them, SnSe has attracted significant attention due to its promising performance in both p-type and n-type crystals; in particular, a higher out-of-plane ZT value could be achieved in n-type SnSe due to its 3D charge and 2D phonon transports. In this work, the thermoelectric transport properties of n-type polycrystalline SnSe were investigated with an emphasis on the out-of-plane transport through producing textural microstructure. The textures were fabricated using mechanical alloying and repeated spark plasma sintering (SPS), as a kind of hot pressing, aimed at producing strong anisotropic transports in n-type polycrystalline SnSe as that in crystalline SnSe. Results show that the lowest thermal conductivity of 0.36 Wm

at 783 K along both parallel and perpendicular directions. The combination of large isotropic power factor and low anisotropic thermal conductivity leads to a maximum ZT of 1.5 at 783 K. The high performance elucidates the outstanding electrical and thermal transport behaviors in n-type polycrystalline SnSe, and a higher thermoelectric performance can be expected with future optimizing texture in n-type polycrystalline SnSe.

PHY Research Is Sick but Curable: An Empirical Analysis

Published: November 2019

The controversy and argument on the usefulness of the physical layer (PHY) academic research for wireless communications are long-standing since the cellular communication paradigm gets to its maturity. In particular, researchers suspect that the performance improvement in cellular communications is primarily attributable to the increases in telecommunication infrastructure and radio spectrum instead of the PHY academic research, whereas concrete evidence is lacking. To respond to this controversy from an objective perspective, we employ econometric approaches to quantify the contributions of the PHY academic research and other performance determinants. Through empirical analysis and the quantitative evidence obtained, albeit preliminary, we shed light on the following issues: 1) what determines the cross-national differences in cellular network performance; 2) to what extent the PHY academic research and other factors affect cellular network performance; 3) what suggestions we can obtain from the data analysis for the stakeholders of the PHY research. To the best of our knowledge, this article is the first `empirical telecommunication research,' and the first effort to involve econometric methodologies to evaluate the usefulness of the PHY academic research.
Power Angle Small-Signal Stability Analysis of Grid-Forming Wind Turbine Inverter Based on VSM Control
Authors: Lu Liang , Göksu Ömer , Cutululis Nicolaos Antonio
Published: November 2019

This paper introduces a virtual synchronous machine (VSM) control scheme which is based on a minimized emulation of the model of a synchronous generator (SG) for a grid-forming wind turbine (WT) inverter. Based on this VSM control scheme, state-space representation and block diagram of the small-signal model for the VSM-controlled grid-forming inverter connected to an infinite bus are derived, which are used for small-signal stability analysis of the power angle in the VSM control scheme. This power angle small-signal stability (PAS) analysis is proposed as a simpler way for analyzing the influence on the rotor angle stability of power system from large share of VSM-controlled grid-forming inverters. Influence of parameters in the power loop of the control scheme on the PAS is investigated by analyzing the eigenvalue trajectories of the state matrix.

Güneş enerjisi en uygun alternatif enerji
kaynağıdır; buna ek olarak güneş enerjisi teknolojilerinin uygulanması,
elektrik enerjisi taleplerini güvenceye almanın yanı sıra çevre kirliliği ve
elektrik üretim maliyetlerini de azaltabilir. Bu çalışmada, maksimum güç
noktası takip (MGNT) sistemlerinde kullanılan üç algoritmanın değerlendirilmesi
ele alınmaktadır. Bunlar sırası ile Değiştir ve Gözetle (D&G), Artımlı
İletkenlik (Aİ) ve Bulanık Mantık (BM) tabanlı algoritmalardır. Bu algoritmalar
basitliği ve gerçekleştirme kolaylığı nedeniyle MGNT'de en çok kullanılanlar
olarak kabul edilirler. Algoritmalar Matlab/Simulink ortamında tasarlanmış ve
üç algoritmanın matematik modelleri çeşitli hava koşullarında test edilmiştir.
Benzetimler sonunda bu üç algoritma içerisinden bulanık mantık algoritmasının
diğerlerine oranla daha fazla enerji sağlayabildiği, daha az salınım yaptığı ve
değişken hava koşulları altında daha hızlı yanıt verdiği gözlenmiştir.
