Ms Zahra Mirbagheri
S. Zahra Mirbagheri graduated in Electronics Engineering in 2005, from Islamic Azad university of Najaf-Abad (Isfahan). Having worked in Mobarakeh steel complex on the behalves of some companies for about 4 years, started her master of engineering in University of Malaya, Kuala Lumpur, Malaysia in Electro manufacturing, 2011. She has graduated with distinction in 2013, her research project was about maximum power point tracking for a stand alone PV system. She have the experience of working in a private company in Petaling jaya, Kuala Lumpur, as an electrical engineer, for some months before she moved to Melbourne and starting her PhD in The Melbourne University. Now she is a PhD Candidate at The University of Melbourne, from September 2014.
PhD research project: Optimal control of partially shaded PV solar system in grid connected and islanding modes of operation
The aim of this research is to use a combination of conventional methods of MPPT (Incremental conductance or P&O) with artificial intelligent methods to find the best algorithm for tracking in partially shading condition. According to this method the efficiency will be improved and tracking time will be decreased. Either Inc. Cond or P&O will be used with variable step size method and AI algorithm will be applied to control the step size and PID controller. Furthermore, unlike most cases in this research simultaneously the topology of PV system is going to be modified. In one hand, there is an appropriate topology for lower power rate application; which is called “AC Modules”, in this structure inverters connect to each module directly. It removes the losses due to mismatch between modules and inverter, as well as it supports optimal adjustment between the module and the inverter. Moreover, the hot-spot risk is removed. All this together; a better efficiency may be achieved. It also includes the possibility of an easy enlarging of the system, due to the modular structure. The opportunity to become a ‘plug and play’ device, which can be used by persons without any education in electrical installations, is also an inherent feature. On the other hand, this topology is just used for lower power rate applications; the aim of this research is to improve the topology to enhance the power level rate.
