An algorithm for estimating derating of induction motors supplied with under/over unbalanced voltages using response surface methodology
Şen, Merve; Balcı, Murat Erhan; Aleem, Shady H. E. Abdel (Inst Engineering Technology-Iet, 2017)One of the adverse effects of unbalanced three-phase voltages on the induction motors (IMs) is overheating of the windings. The IMs should be loaded at less than their rated power in case of unbalanced supply voltages to ... -
Effective utilization of cables and transformers using passive filters for non-linear loads
Aleem, Shady H. E. Abdel; Balcı, Murat Erhan; Sakar, Selçuk (Elsevier Sci Ltd, 2015)In the literature, it is well known that transformers and cables have excessive losses or overheating under non-sinusoidal current conditions. Accordingly, they have reduced current carrying capabilities (or loading ... -
Hosting capacity assessment and improvement for photovoltaic-based distributed generation in distorted distribution networks
Sakar, Selçuk; Balcı, Murat Erhan; Aleem, Shady H. E. Abdel; Zobaa, Ahmed F. (IEEE, 2016)In this paper, the hosting (or maximum allowable) capacity of a photovoltaic (PV)-based distributed generation (DG) unit for a typical two bus distorted distribution system, is analyzed. The harmonic constraints, total and ... -
Integration of large- scale pv plants in non-sinusoidal environments: considerations on hosting capacity and harmonic distortion limits
Sakar, Selçuk; Balcı, Murat Erhan; Aleem, Shady H. E. Abdel; Zobaa, Ahmed F. (Pergamon-Elsevier Science Ltd, 2018)Distributed generation (DG) penetration in a system may affect power quality, and energy efficiency, if it exceeds a particular value, known as the system's hosting capacity (HC). In this work, a comprehensive overview of ... -
Optimal design and analysis of anti-resonance c-type high-pass filters
Lamlom, Ahmed; Ibrahim, Ahmed; Balcı, Murat Erhan; Karadeniz, Alp; Aleem, Shady H. E. Abdel (IEEE, 2017)Harmonic distortion is a matter of interest in all sectors of power system networks with their different voltage levels, particularly with the spread of harmonic-source nonlinear loads among all industrial, commercial, and ... -
Optimal design of single-tuned passive filters using response surface methodology
Sakar, Selçuk; Karaoğlan, Aslan Deniz; Balcı, Murat Erhan; Aleem, Shady H. E. Abdel; Zobaa, Ahmed F. (IEEE, 2015)This paper presents an approach based on Response Surface Methodology (RSM) to find the optimal parameters of the single-tuned passive filters for harmonic mitigation. The main advantages of RSM can be underlined as easy ... -
Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions
Aleem, Shady H. E. Abdel; Balcı, Murat Erhan; Zobaa, Ahmed F.; Sakar, Selçuk (IEEE, 2014)Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current. In this ... -
Power conditioning using dynamic voltage restorers under different voltage sag types
Saeed, Ahmed M.; Aleem, Shady H. E. Abdel; İbrahim, Ahmed M.; El-Zahab, Essam E. A.; Balcı, Murat Erhan (Elsevier Science Bv, 2016)Voltage sags can be symmetrical or unsymmetrical depending on the causes of the sag. At the present time, one of the most common procedures for mitigating voltage sags is by the use of dynamic voltage restorers (DVRs). By ...
