Impact of Loads on Synchronization Stability of Grid-Tied Inverters using Dynamic Phasors
Authors: Maulik Sugoto 
Published: August 2023

<p>The integration of renewable energy resources is a prevailing trend in modern power systems. Wind and solar energy are key among these renewables, linked to the grid via power electronic converters. These converters require precise synchronization of their output with the grid, achieved through a phase-locked loop (PLL). The PLL’s ability to accurately track the grid voltage phase directly impacts synchronization stability. Moreover, stability relies on the converter’s controller, loads, and grid stiffness. The inclusion of these cross-linked dynamics culminates in a complex analytical model. However, commonly used reduced-order models often omit load dynamics, limiting the obtained insights. Addressing these limitations, this paper introduces a comprehensive method to model a 3- phase grid-tied inverter with an SRF-PLL and local loads, utilizing dynamic phasors. The approach evaluates the impact of system parameters, especially load configuration, on synchronization stability via eigenvalue analysis of the linearized state-space model. This model is apt for investigating weak grids and islanded distributed generation (DG) with diverse local loads. The model showcases stability boundaries, aiding the design of robust renewable energy systems.<br>

Influence of the Self-Interference Channel Model on the Performance of a Full-Duplex MIMO System
Authors: Chen Xuan , Savaux Vincent , Savelli Patrick 
Published: August 2023

<p>In this paper, we study the behavior of a multiple-input multiple-output (MIMO) full-duplex (FD) system according to two different models of the self-interference (SI) channel inherent to the FD communication strategy: the spherical wave model (SWM) and the planar wave model (PWM). More precisely, we evaluate the received SI power at the receiver antenna array by changing the relative geometrical position of the transmitter antenna array in respect to the latter. Our study shows a significant difference between the two models. In particular we theoretically show as well as through simulation that the SWM for the SI channel is more precise than the PWM, and should then be considered for practical applications of the FD concept.</p>
On a conjecture for the algebraic transfer in generic families of internal degrees
Authors: Võ Phúc Đặng 
Published: August 2023

<p>Let $\mathbb F_2$ denote the binary field. Write $\mathscr A$ for the Steenrod ring over $\mathbb F_2.$ In this paper, we study Singer's conjecture \cite{Singer} for the algebraic transfers of ranks 5 and 6 in the generic families of internal degrees. The Singer algebraic transfer stands as a valuable instrument for unraveling the intricate structure of the cohomology ${\rm Ext}_{\mathscr A}^{s,k} := {\rm Ext}_{\mathscr A}^{s}(\mathbb F_2, \Sigma^{k}\mathbb F_2)$ of the (mod-2) Steenrod ring. Remarkably, we have shown that the indecomposable element $y\in {\rm Ext}_{\mathscr A}^{6,44}$ is not in the image of the sixth algebraic transfer. </p>

KI-Einsatz in KMU: Einstiegshürden ausräumen/Clearing entry hurdles for AI deployment in SMEs – Artificial intelligence for German SMEs
Authors: Heider Imanuel , Yu Huitian , Krischke Nikolai , Wirth Benjamin , Fleischer Jürgen 
Published: August 2023

Anwendungen künstlicher Intelligenz (KI) bieten für die Produktionstechnik enorme Potenziale. Diese sind vor allem in kleinen und mittelständischen Unternehmen (KMU) nicht umfassend ausgeschöpft. Ein Grund dafür ist, dass die Umsetzung von KI-Projekten Ressourcen benötigt, welche die KMU oft nicht eigenständig bereitstellen können. Vorgestellt wird ein Konzept, um das Deployment von KI-Modellen im Produktionsumfeld zu begleite. Es ist einsetzbar unter verschiedensten Randbedingungen und mit geringem Eigenentwicklungsanteil.

Artificial intelligence (AI) holds enormous potential for application in the field of production engineering. SMEs, in particular, are not ready to fully exploit these opportunities. One reason is that implementing AI projects requires resources that SMEs often are not able to provide on their own. This paper presents an approach to accompany the deployment of AI models in the production environment. It can be applied with various boundary conditions and a low proportion of in-house development.
