Assesment of Power Quality Disturbances For Grid Integration of PV Power Plants
Bayrak, Gökay; Yılmaz, Alper (2019)Power Quality problems, which have become an important consumer issue in recent years, are defined as changes in voltage, current, or frequency in the power system. Among the factors affecting energy quality in grid-connected ... -
DWT-Based Islanding Detection Method for DFIG-typed WTs
Yılmaz, Alper; Bayrak, Gökay (Institute of Electrical and Electronics Engineers Inc., 2020)In this study, it is aimed to image the transparent objects by applying the phase shifting technique to lateral shearing digital holographic microscopy. In order to extract the phase information from interference patterns ... -
An improved automated PQD classification method for distributed generators with hybrid SVM-based approach using un-decimated wavelet transform
Yılmaz, Alper; Kucuker, Ahmet; Bayrak, Gökay; Ertekin, Davut; Shafie-Khah, Miadreza; Guerrero, Josep M. (Elsevier, 2021)Artificial intelligence (AI) approaches are usually coupled with the wavelet transform (WT) for feature extraction to classify the power quality disturbances (PQDs). Therefore, selecting a useful WT-based signal processing ... -
A new signal processing-based islanding detection method using pyramidal algorithm with undecimated wavelet transform for distributed generators of hydrogen energy
Yılmaz, Alper; Bayrak, Gökay (PERGAMON-ELSEVIER SCIENCE LTD, 2022)Machine learning-based fault detection methods are frequently combined with wavelet transform (WT) to detect an unintentional islanding condition. In contrast to this condition, these methods have long detection and ... -
A real-time UWT-based intelligent fault detection method for PV-based microgrids
Yılmaz, Alper; Bayrak, Gökay (Elsevier Science Sa, 2019)In this paper, a new un-decimated wavelet transform (UWT)-based fault detection method is proposed to overcome the limitations of WT-based methods in real-time applications. For the first time, UWT method is used to detect ... -
Signal processing-based automated fault detection methods for smart grids
Bayrak, Gökay; Yılmaz, Alper (Springer Science and Business Media Deutschland GmbH, 2020)Automated fault detection methods (AFDMs) are required to provide a more reliable and stable power system operation and protection. The faults in distributed generators (DGs) connected to the grid must be cleared on time ... -
Şebeke Bağlantılı Fotovoltaik (PV) Sistemlerin Mevcut Elektrik Şebekesi ile Entegrasyonu ve Güç Sistemine Etkileri
Yılmaz, Alper (Bursa Teknik Üniversitesi, 2018)Son yıllarda, güç sistemlerinde arıza ve güç kalitesi konuları üzerine yapılan çalışmalarda artış olsa da, hataların otomatik olarak tespit edildiği gerçek zamanlı sinyal işleme tabanlı çalışmalar sınırlı sayıdadır. ...
