Dr Hossein Tafti

Hossein Dehghani Tafti received the B.Sc. and M.Sc. degrees in electrical engineering and power system engineering from the Amirkabir University of Technology, Tehran, Iran, in 2009 and 2011, respectively, and the Ph.D. degree in electrical engineering from Nanyang Technological University, Singapore, in 2018.

From January 2018 to April 2020, he was a Research Fellow at Nanyang Technological University, where he worked on the control of photovoltaic systems for grid support. From May 2020 to May 2021, he was a senior research associate with the University of New South Wales, Sydney, Australia, where he worked on the modeling and testing of commercial photovoltaic inverters.

He is currently a research fellow at the Department of Electrical, Electronic and Computer Engineering, University of Western Australia, Perth, WA, where he is involved in designing a 1MVA energy storage system in conjunction with Magellan Power Pty Ltd. His research interest includes the grid integration of renewable energy sources, in particular, photovoltaics and energy storage and the design and control of multilevel power converters.

Distributed Power Reserve Control in Grid-Connected Cascaded H-Bridge Converter-Based Photovoltaic Systems

November 12, 2024 8:51 am
Grid-connected photovoltaic (PV) systems enhance grid stability during frequency fluctuations by adopting power reserve control (PRC) and contributing to frequency regulation. The cascaded H-bridge (CHB) converter is a suitable choice for large-scale photovoltaic systems. This paper introduces a distributed PRC strategy designed for CHB-based PV systems, necessitating minimal inter-module communication...Read More

Hybrid global flexible power point tracking algorithm for photovoltaic systems

October 21, 2024 2:41 pm
Frequency support in grid-connected photovoltaic systems is achieved by employing flexible power point tracking (FPPT) algorithms. Subsequently, according to the grid frequency requirements, the PV power is curtailed to a power reference, unlike the traditional method of operating the PV at the maximum power point. In practical cases, the PV...Read More

Enhanced energy storage utilization under partial shading conditions in a microgrid with flexible photovoltaic power control

July 25, 2024 2:19 pm
Flexible power point tracking (FPPT)-based photovoltaic (PV) controls are widely applied to mitigate PV power fluctuations due to intermittent irradiance changes. In dc microgrid (dcMG) systems, the utilization of a battery energy storage system (BESS) can be alleviated by adjusting the PV power generation to meet the demand. However, conventional...Read More
