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.

Observer-Based Distributed Control of Grid-Connected Cascaded Multilevel Converters

March 31, 2026 4:47 pm
The inherently modular characteristics of multilevel cascaded converters are reduced if centralized control and communication architectures are required within the converter system. In contrast, this paper presents a distributed control and communication approach for a cascaded converter, where the switching and control actions of each individual submodule (SM) are determined...Read More

Noise-Resilient Protection Algorithm in Renewable Integrated Microgrid Based on Zero-Sequence Current Detection, Differential Faulty Energy, VMD, and SVM

March 23, 2026 11:22 am
The integration of renewable energy sources into microgrids introduces significant challenges in protection, stability, and reliability. Reliable protection of renewable integrated microgrids remains a major challenge due to the presence of harmonics, switching transients, and noise contamination that compromise conventional fault detection schemes. The work in this paper suggests the...Read More

Performance Evaluation of a Flexible Power Point Tracking Strategy for Extending the Operational Lifetime of Solar Battery Banks

February 1, 2026 10:14 am
Standalone photovoltaic systems play an important role in providing reliable renewable energy in remote areas. These systems depend heavily on battery energy storage, especially lithium iron phosphate batteries, which are known for their safety and long cycle life. However, battery degradation remains a major challenge, as high charging currents, temperature...Read More

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
