Yeni Yayınım: Towards sustainable solar energy solutions: Harnessing supercapacitors in PV systems

Abstract: The  integration  of  supercapacitors  in  photovoltaic  (PV)  energy  systems  holds immense  potential  for  enhancing  energy  storage,  reliability,  and  efficiency.  This  article provides a comprehensive overview of recent advancements, challenges, and opportunities in the    utilization    of    supercapacitors    within    PV    systems.    Fundamental    principles    of supercapacitor  operation,  including  charge  storage  mechanisms  and  electrode  materials,  are discussed,  highlighting  their  unique  advantages  such  as  high  power  density  and  rapid charge/discharge  capabilities.  Various  integration  strategies,  including  parallel  and  series configurations,  as  well  as  system-level  control  algorithms, are  examined  to optimize  energy management  and  performance.  Case   studies  and  real-world  examples  demonstrate  the effectiveness  of  integrated  PV  and  supercapacitor  systems  across  different  applications  and scales.  According  to  the  results  of  the  research,  235  publications  have  been  made  on  the subject  in  the  last  fifteen  years  and  the  number  of  publications  has  doubled  in  the  last  five years. Additionally, future research directions focus on improving energy density, efficiency, and cost-effectiveness, as well as addressing challenges related to temperature sensitivity and system scalability. Overall, the integration of supercapacitors in PV systems offers promising solutions for advancing sustainable energy solutions and accelerating the transition towards a cleaner, greener future.

Abstract

This paper presents a grey-box model of a DC/DC boost converter for PV energy systems. The proposed model contains a white-box model part and a black-box model part together to prepare a better model for the PV boost converter. The white-box model part is used for knowledge of the circuit by mathematical equations since the black-box model part is used for unknown parameters such as temperature and electromagnetic interference. The black-box part of the proposed model is created by a nonlinear system identification of a real boost converter circuit with an artificial neural network. The precision of the mathematical model and the advantages of the fast prediction ability of the artificial neural network were used together. The proposed grey-box model is compared with the existing state-space and black-box models and experimental results. The results of the study showed that the average correlation between the proposed grey-box model output and the experimental results is 97.52%. Therefore, the proposed model can be used for analyzing DC/DC boost converter output characteristics before field applications.

Teaching mobility Kerim KARABACAK (Dumlupinar Univeristy)

From March 4th to March 8th, 2024, we had the honor to welcome our colleague Dr. Kerim KARABACAK, assistant professor of the Faculty of Electronics and Automation at the University of Kutahya Dumlupinar (Turkey) for a teaching mobility at UTTOP. His research work based on modelling and identification of power electronics design and control systems as well as renewable energy systems made it possible for him to conceive a course designed for our third year students. He taught the whole S5 promotion about Modelling systems during an introductory two-hour course and then applied the theory during three practical courses with simulations on the Matlab software within smaller groups of students along the week.

Thanks to Pr Mourad BENOUSSAAD who coordinated his teaching and training program, Dr. Kerim KARABACAK had the opportunity to be introduced to several lecturers of the Production Engineering Laboratory: Philippe FILLATREAU, Baptiste TRAJIN and Paul-Etienne VIDAL to discover their research on virtual reality and efficiency of electrical energy conversion systems.

IRO team, ENIT students and teachers are very happy about this fruitful collaboration that will be continued in the future.
