Article Citation - WoS: 201Citation - Scopus: 342Analysis and Mitigation of Power Quality Issues in Distributed Generation Systems Using Custom Power Devices(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018) Hossain, Eklas; Tur, Mehmet Rida; Padmanaban, Sanjeevikumar; Ay, Selim; Khan, ImtiajThis paper discusses the power quality issues for distributed generation systems based on renewable energy sources, such as solar and wind energy. A thorough discussion about the power quality issues is conducted here. This paper starts with the power quality issues, followed by discussions of basic standards. A comprehensive study of power quality in power systems, including the systems with dc and renewable sources is done in this paper. Power quality monitoring techniques and possible solutions of the power quality issues for the power systems are elaborately studied. Then, we analyze the methods of mitigation of these problems using custom power devices, such as D-STATCOM, UPQC, UPS, TVSS, DVR, etc., for micro grid systems. For renewable energy systems, STATCOM can be a potential choice due to its several advantages, whereas spinning reserve can enhance the power quality in traditional systems. At Last, we study the power quality in dc systems. Simpler arrangement and higher reliability are two main advantages of the dc systems though it faces other power quality issues, such as instability and poor detection of faults.Conference Object Citation - WoS: 2Citation - Scopus: 4Analysis of Feature Selection Approaches in Large Scale Cyber Intelligence Data with Deep Learning(IEEE, 2020) Ahmetoğlu, Hüseyin; Daş, ResulAğ sistemlerinin her geçen gün katlanarak büyüyen boyutu, saldırı yoğunluğunun ve türlerinin de artmasına neden olmaktadır. Ağ içerisinde bu saldırıların tespiti, ağ güvenliğinin başlıca problemlerindendir. Saldırı tespit sistemleri, bu problemle başa çıkmak için geliştirilen bir yaklaşımdır. Saldırı tespit sistemlerinde işlenen büyük boyutlu veriler beraberinde karmaşıklığ da getirmektedir. Bu çalışma, veri kümelerindeki karmaşıklığı gidermek için 6 farklı öznitelik seçme algoritmasının incelenmesini ve bu algoritmaların sınıflandırma modellerindeki performanslarının karşılaştırılmasını içermektedir. Bu performanslar, açık erişimli olarak sunulan CICIDS2017 veri seti üzerinde uygulanan Derin Öğrenme modelleri ile analiz edilmiştir. Bu işlem sırasında algoritmaların test sonuçları hem kendi aralarında hem de veri setinin orijinal haliyle karşılaştırılmıştır. Uygulama sırasında veri kümesindeki öznitelik sayıları çoklu sınıflandırma için 78’den 25’e, ikili sınıflandırma için 8’e düşürülmüştür. Elde edilen başarı oranları bütün uygulamalarda %92’nin üzerindedir.Article Citation - WoS: 15Citation - Scopus: 22Analysis of Open Circuit Voltage MPPT Method with Analytical Analysis with Perturb and Observe (P&O) MPPT Method in PV Systems(Taylor and Francis Ltd., 2023) Çakmak, Fevzi; Aydoğmuş, Zafer; Tür, Mehmet RıdaThis study conducts a comprehensive comparison between two prominent Maximum Power Point Tracking (MPPT) techniques employed in solar energy systems: the Perturb and Observe (P&O) method and the Analytical Solution Fractional Open Circuit Voltage (ASFOCV) method. To assess the effectiveness of these MPPT approaches, a simulation study was conducted using four SHARP NDQ295 model photovoltaic panels, configured as two panels in series and two in parallel. Both the P&O and ASFOCV MPPT methods were evaluated under various scenarios of radiation levels and temperature changes. The results unequivocally demonstrate the superior performance of the ASFOCV MPPT method over the P&O MPPT method. The ASFOCV method notably enhanced converter output power by up to 5% when compared to the P&O method, leading to more efficient energy production. Furthermore, the ASFOCV method exhibited rapid stabilization of output voltage during abrupt weather changes, outperforming the P&O method in this regard. This study underscores the potential of the ASFOCV MPPT method to enhance the efficiency of solar energy systems and its adaptability to fluctuating environmental conditions. Future research endeavors could focus on mitigating the ASFOCV method’s sensitivity to temperature variations and conducting real-world applications to further investigate its performance under practical circumstances.Book Part Cozguden Dugume, Dugumden Motife Bergama Halilariy(MILLI FOLKLOR, 2022) Ekinci, EsraCozguden Dugume, Dugumden Motife Bergama HalilariyArticle Citation - WoS: 5Citation - Scopus: 5How do family influence on career choices and perceived social support affect students’ life satisfaction in Turkey? The role of vocational outcome expectations as mediator(SpringerLink, 2023) Aslan, Yavuz; Koçak, OrhanThis study aimed to examine the relationships between family infuence on career choices with perceived social support, vocational outcome expectations, and life satisfaction of university students. Correlational research method was used in the study. The results showed that family infuence on career choices and perceived social support were positive and signifcant predictors of vocational outcome expectations and life satisfaction. In addition, vocational outcome expectations was a positive and signifcant predictor of life satisfaction. Vocational outcome expectations partially mediated the relationship between family infuence on career choices, perceived social support, and life satisfaction.
