EPE/TDHVL PhD student selected for Best Paper Session at 2025 Power and Energy Society general meeting
Our paper entitled “Boundary Analysis of Damping Methods for Virtual Synchronous Generators”, authored by Xi Luo (PhD student), Dr Yadala Pavankumar, Dr Stratis Batzelis and Dr Abhinav Kumar Singh from the Electrical Power Engineering (EPE) group and Tony Davies High Voltage Laboratory (TDHVL), University of Southampton, was selected for presentation in the Best Paper Session at the 2025 IEEE Power and Energy Society General Meeting (PESGM). This marks the second time our team’s work has been selected for this session within 3 years.
This work maps the stability boundaries and feasibility region of typical virtual synchronous generator and phase-locked loop damping units, exploring how control parameters interact with grid impedance. It provides a comprehensive sensitivity analysis and validation through time-domain simulations
In addition, another paper “Seamless Transition between Grid Forming and Grid Following Inverters based on Online Grid Impedance Estimation” was included in the Paper Forum Session at PESGM. This paper proposes an automatic smooth-switching strategy between grid-following and grid-forming inverters using online grid impedance estimation and hysteresis logic for enhanced operational reliability.
These papers are the outcome of a very fruitful collaboration between the University of Southampton and the National Technical University of Athens (NTUA) within the framework of UNIFORM project. The UNIFORM project focuses on fusing together grid-following and grid-forming control in inverters towards a versatile voltage/current source behaviour and enhanced stability under different grid strengths.
The 2025 IEEE PESGM was held in Austin, Texas from 27th to 31st July 2025. As a leading flagship conference in the global power industry, it brought together practicing power engineers and academics from all over the world. The conference provided an international forum for experts to share, promote, and discuss developments and challenges in electrical power engineering.
