Dynamic Stabilization of DC Microgrids Using ANN-Based Model Predictive Control
Alper Nabi Akpolat;Mohammad Reza Habibi;Hamid Reza Baghaee;Erkan Dursun;Ahmet Emin Kuzucuoğlu;Yongheng Yang;Tomislav Dragičević;Frede Blaabjerg
Over the past decade, the high penetration of renewable-based distributed generation (DG) units has witnessed a considerable rise in electrical networks. In this context, direct current (DC) microgrids based on DGs are being preferred due to having less complexity for the establishment and control. At the same time, they offer higher efficiency and reliability compared to their alternating current...Show More
In a microgrid, photovoltaic (PV) systems are broadly preferred with energy storage systems (ESSs) that form small-sized direct current (DC) microgrids. They are also termed local grids i.e., DC nanogrids, which feed the local consumers to some extent in the next decades. Therefore, ESSs enable the DC nanogrids more flexible and stable by preserving the intermittent nature of renewables. Yet still...Show More
Design Implementation and Operation of an Education Laboratory-Scale Microgrid
Alper Nabi Akpolat;Yongheng Yang;Frede Blaabjerg;Erkan Dursun;Ahmet Emin Kuzucuoğlu
To enable more wide-scale exploitation of renewable energy sources (RESs), distributed generations (DGs) as in microgrids have gained prominence recently. This study describes the design, modeling, implementation, and operation of a microgrid, in which a standalone hybrid power system has been installed for an education and research laboratory. The unstable nature of RESs results in power compatib...Show More
Sensorless Control of DC Microgrid Based on Artificial Intelligence
Alper Nabi Akpolat;Mohammad Reza Habibi;Erkan Dursun;Ahmet Emin Kuzucuoğlu;Yongheng Yang;Tomislav Dragičević;Frede Blaabjerg
Nowadays, DC microgrids are preferred in the field of renewable energy. The autonomous DC microgrids aim to provide smooth power flow from renewables to loads. While satisfying certain load profiles and sustaining the power as the desired level, the control of power converters is considerable. To ascend the resilience of DC microgrids, battery storage systems (BSSs) are also used as a backup unit ...Show More
AI-Aided Control of a Power Converter in Wind Energy Conversion System
2020 Innovations in Intelligent Systems and Applications Conference (ASYU)
Year: 2020 | Conference Paper |
Cited by: Papers (10)
Over the last decades, to adopt high penetration of renewable energy sources (RESs) in electrical energy systems, distributed energy resources (DERs) have become prominent. Due to easy attainability status of small wind turbines (WTs), wind energy conversion systems (WECSs) are feasible applications for small customers, especially in windy areas. The next decade is likely to witness a considerable...Show More
Modeling Photovoltaic String in PLECS Under Partial Shading
Alper Nabi Akpolat;Yongheng Yang;Frede Blaabjerg;Erkan Dursun;Ahmet Emin Kuzucuoğlu
2019 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)
Year: 2019 | Conference Paper |
Cited by: Papers (7)
The industry of solar energy and its application areas have developed and received much attention over the last two decades. Therefore, the types of photovoltaic (PV) system simulations are investigated and mostly discussed models close to the physical behaviour of a PV panel or system. Under the real conditions such as cloud coverage, the shadows of nearby objects, dusty air, and dirty surface ar...Show More
Identification of Tumor area from Brain MR Image
2016 24th Signal Processing and Communication Application Conference (SIU)
Year: 2016 | Conference Paper |
Cited by: Papers (1)
The analysis of Magnetic Resonance Image has an important role in definite detection of Brain Tumor. The shape, location and size of tumor are examined by Radiology specialist to diagnose and plan treatment. In the intense work pace, it's not possible to get results quickly. At this scheme, unnoticed information can be recovered by an image processing algorithm. In this study, at database images w...Show More
Identification of diseased leukocytes cells from blood smear
2013 21st Signal Processing and Communications Applications Conference (SIU)
Year: 2013 | Conference Paper |
Cited by: Papers (1)
The blood smear analysis has an important role in definite diagnosis of leukemia disease. The WBC's shapes and numbers in a smear area are examined by Hematology experts to diagnose leukemia. The smear stain process and microscope luminance are blinked because of the intense working tempo. At this scheme, unnoticed information about cells can be recovered by an image processing. In this study, at ...Show More
