Active and Reactive Power Load Profiling Using Dimensionality Reduction Techniques and Clustering
Yetkin, E. Fatih; Ceylan, Oğuzhan; Papadopoulos, Theofilos A.; Kazaki, Anastasia G.; Barzegkar-Ntovom, Georgios A. (Institute of Electrical and Electronics Engineers Inc., 2019)This paper proposes a methodology to characterize active and reactive power load profiles. Specifically, the approach makes use of fast Fourier Transform for conversion into frequency domain, principle component analysis ... -
Generic dynamic load modelling using cluster analysis
Barzegkar-Ntovom, Georgios A.; Ceylan, Oğuzhan; Papadopoulos, Theofilos A.; Yetkin, E. Fatih (IEEE, 2018)In this paper a new generic load modelling procedure is proposed based on the application of cluster analysis on load model parameters identified from measured dynamic responses. The performance of the proposed approach ... -
Two-layer earth structure parameter estimation and seasonal analysis
Papadopoulos, Theofilos A.; Ceylan, Oğuzhan; Papagiannis, Grigoris K. (IEEE, 2018)The determination of soil parameters is an important topic regarding the safe and efficient design of electrical grounding systems as well as the accurate calculation of the per-unit-length parameters of overhead transmission ...
