An algorithm for optimal sizing of the capacitor banks under nonsinusoidal and unbalanced conditions
Balcı, Murat Erhan; Abdel Aleem, Shady H.E.; Zobaa, Ahmed F.; Sakar, Selçuk (Bentham Science Publishers B.V., 2014)In non-sinusoidal and unbalanced systems, optimal sizing of the capacitor banks is not a straightforward task as in sinusoidal and balanced systems. In this paper, by means of qualitative and quantitative analysis, it is ... -
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 ... -
Increasing PV hosting capacity in distorted distribution systems using passive harmonic filtering
Sakar, Selçuk; Balcı, Murat Erhan; Aleem, Shady H.E. Abdel; Zobaa, Ahmed F. (Elsevier Science Sa, 2017)Adding new capacity expansion alternatives using distributed generation (DG) technologies, particularly penetration of renewable energy, has several economical, and technical advantages such as the reduced system costs, ... -
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 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 ... -
Optimal resonance-free third-order high-pass filters based on minimization of the total cost of the filters using Crow Search Algorithm
Aleem, Shady H.E. Abdel; Zobaa, Ahmed F.; Balcı, Murat Erhan (Elsevier Science Sa, 2017)The most common damped filters (DFs) are the second-order, third-order, C-type, and double-tuned filters. Other DFs such as the first-order and band-pass filters exist, but their high operating losses considerably diminish ...
