“…YFK sistemlerde zaman gecikmesi dikkate alınarak kararlılık analizlerini, kararlılık gecikme pay değerlerinin hesaplanması ve denetleyici parametre tasarımı olarak çoğunlukla iki grup altında ifade edilebilir. Klasik YFK [25][26][27][28], EA içeren YFK [29][30][31][32], mikro-şebeke YFK sistemleri [34] ve DTC kontrol çevrimi içeren YFK sistemleri [35,36] için, frekans düzleminde ve zaman düzleminde yöntemler kullanılarak kararlılık gecikme payları hesaplanmış ve gecikmeye bağlı kararlılık analizleri gerçekleştirilmiştir. [35] ve [36]'da yapılan çalışmalar, bir ve iki bölgeli YFK-DTC sistemleri için frekans düzleminde kullanılan Rekasius yerine koyma yöntemi ve üstel terimlerin yok edilmesi yöntemi yardımıyla bir PI denetleyici kazanç seti için sistemin kararlılık gecikme payları hesaplamıştır.…”

Bu çalışmada, dinamik talep cevabı (DTC) ve haberleşme zaman gecikmesi içeren iki bölgeli yük frekans kontrol (YFK-DTC) sisteminin kararlılık sınır eğrisi yöntemi kullanılarak denetleyici parametre düzleminde kararlılık bölgeleri hesaplanmıştır. DTC kontrol, kontrol edilebilir yük gruplarını frekans kontrol servisine dahil ederek, üretim ve puant yük talebi arasında dengenin daha kısa sürede sağlanması ve yenilenebilir enerji kaynaklarında güç dengesizlikleri problemlerine karşı önemli bir çözüm sunmaktadır. DTC kontrol mekanizmasının yük frekans kontrol sistemlerinde kullanımı, sistemin güvenliği ve güvenilirliğini sağlamasına rağmen, haberleşme ağlarından kaynaklanan zaman gecikmeleri, denetleyici performansını ve sistemin kararlılığını olumsuz etkileyebilmektedir. Dolayısıyla, bu çalışma zaman gecikmesi içeren iki bölgeli YFK-DTC sisteminin kararlılığını garanti edecek tüm oransal-integral (PI) denetleyici kazanç değerlerini elde etmektedir. Bu amaçla, zaman gecikmeli YFK-DTC sisteminin denetleyici parametre düzleminde kararlılık bölgelerini oluşturan kompleks kök sınır (Complex Root Boundary, CRB) eğrisini ve reel kök sınır (Real Root Boundary, RRB) eğrisini bulmak için kararlılık sınır eğrsi yöntemi kullanılmıştır. Elde edilen teorik sonuçların doğruluğu, quasi-polynomial mapping root (QPmR) algoritması ve zaman düzleminde yapılan benzetim çalışmaları ile gösterilmiştir. Sonuçlar, DTC kontrol çevriminin katkısı ile zaman gecikmeli YFK sisteminin kararlılık bölgelerinin ve kararlılık payının arttığını göstermektedir.

“…Thus, this traditional method of communication is gradually being replaced by open networks (Aluko et al, 2021). However, the application of open communication networks in power systems has brought new problems such as communication delays and limited network bandwidth constraints (Yuan et al, 2021). Therefore, how to improve the utilization of network resources has been the focus of investigation on the power system in the modern communication network environment.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

Introduction: The urban distribution system plays a crucial role in efficient power distribution within urban areas. The increasing frequency and intensity of extreme events in recent years pose significant challenges to the reliable operation of urban distribution systems. While extensive research focuses on emergency frequency control strategies for large-scale power grids, there is a need for targeted attention to address the emergency frequency control challenges arising when the urban distribution system becomes isolated from the superior power grid due to extreme events.Methods: This paper aims to enhance the system's resilience to extreme events by investigating the coordinated regulation of various resources within the urban distribution system. The studied resources include synchronous generators, wind farms, battery energy storage systems, temperature control loads, and conventional load resources. A reduced-order model for the multi-resource system’s frequency response is established. Analytical expressions for key parameters, including the lowest system frequency, lowest point time, and quasi-steady state frequency, are derived.Results: To address the challenge of multi-resource coordinated regulation, an emergency frequency control strategy is proposed. This strategy takes into account the system safety frequency constraint, resource control amount constraint, and line power flow constraint. Simulations are conducted using the MATLAB/Simulink platform, considering IEEE 13 bus and IEEE 33 bus distribution systems as test cases.Discussion: Simulation results demonstrate the effectiveness of the proposed method in regulating the distribution system's resources, ensuring that the lowest frequency remains within the safety threshold of 49.8 Hz. Moreover, the proposed method minimizes control costs and limits load shedding, thereby fully leveraging the capabilities of diverse resources in the urban distribution system. This research contributes valuable insights into addressing emergency frequency control challenges in urban distribution systems during extreme events.
